Debugging is hard - this is a fact of life. Unfortunately, it’s never planned nor expected. It takes too much time, time we could have spent doing cool stuff - like developing new features for our customers. But while there are many articles and productivity tools aimed at writing better code – faster, it seems as though it’s impossible to find resources that teach you how to effectively debug your code. In this talk we’ll explore Visual Studio’s more powerful but lesser known debugging capabilities. We’ll also showcase OzCode and explain how it helps finding and fixing bugs faster.

Beer & Beta by Flockler - Feb 4th 2016
This document discusses how to move fast and fix things by removing fear through automated testing, easy access to browsers and devices from any location, and error notifications. It recommends using CircleCI to automatically run tests before deployment, BrowserStack for remote testing on actual devices from any location, and Opbeat for real-time error reporting with details to help fix issues. The overall message is that these tools can help developers deploy code quickly through continuous integration and testing, while also quickly catching and fixing bugs in production.

Intro to automated testing
This document introduces automated testing as a way to test software in a less time-consuming and error-prone manner than manual testing. It discusses challenges with manual testing like not testing all code paths and missing unintended effects. Automated testing involves writing code to test other code, allowing testing of all code paths more thoroughly. Test-driven development is introduced as an approach where tests are written before code to specify its behavior, with the code then written to pass those tests. Benefits of testing like loose coupling and avoiding unnecessary code are discussed. Frameworks for writing automated tests are also introduced.
Becoming a better programmer - unit testing
This document discusses unit testing and provides tips for programmers to write better unit tests. It begins by defining unit testing as writing tests for specific parts of code or systems, with a unit being the smallest testable part. It then explains why unit testing is important for faster debugging, development and testing. The document recommends writing unit tests after reading design requirements and refactoring tests along with code changes. It provides guidelines for writing good unit tests, such as setting up conditions, calling the method, verifying results, and cleaning up. Overall, the document advocates for unit testing to improve code quality.

Code review
This document discusses how to improve software quality through code reviews. It begins by stating the goals of code review, such as improving code quality, sharing knowledge, and educating developers. It then discusses classification of code reviews from less to more formal. The document outlines some best practices for code reviews, including having a reviewer and author, choosing reviewers strategically, and driving the review in different ways. It provides answers to common questions about organizing effective code reviews and leaves with tips, such as tracking reviewers, using checklists, and ensuring comfortable conditions for all.
How to be proud when you are done
Although all of us speak the same language, each of us uses different meaning of words "soon”, "fine” and "done”. That’s why for one developer "I’m done” means that just a moment ago the part of the code with implemented functionality has been successfully executed, while for another developer it means that code has been committed to repository but without checking if build is green or not on continuous integration server. At the same time "done" of developer-perfectionist means totally refactored and optimized code. And only for "black swan”-developer phrase "I'm done“ means that all tests were passed, new functionality was documented on wiki and a new feature was verified by customer on the demo server.
So if you want to decrease a risk of misunderstanding inside a team or between team and customer you should make agreement about common vision of “definition of done“ and then start using it on a daily basis. In order to prevent losing your time and stepping on the hidden rake during discussion of your done criteria we will share our knowledge about creating compact and most effective “definition of done“. We will talk about lifecycle of this document and about approaches that help you to add important items to it. We will discuss doneness on different levels (preplanning, user story and task development, sprint). And of course we won’t forget to tell you how to create “Definition of Done“ which will satisfy not only your team but your customer as well.

Introductie presentatie behorende bij de workshop TestCafe. Voor workshop zie: https://github.com/jvdieten/testcafe-meetup-malmberg
NYC MeetUp 10.9
William Josephson is the co-founder of Solano Labs, which provides automated testing services. Solano Labs has helped several customers significantly reduce their testing times - for example, reducing tests that previously took 18 hours down to 13 minutes. Automated testing allows organizations to deploy code much more frequently and have fewer failures. It reduces costs by finding bugs quicker and allows engineers to make changes more freely.
The four generations of test automation
A quick presentation comparing the main five test automation frameworks:
Record and Playback
- Data Driven
- Keyword Driven
- Function Driven
- Behaviour Driven
Then presentation separates the frameworks into generation 1 to 3 and rates them against the goal of test automation.
1. Improve Software quality
2. Early detection of bugs (Defects)
3. Reduce (not introduce) project risk
4. Easy to write and maintain by BA, Testing and technical resources
5. Reduced cost and time of development
Humans by the hundred
This document discusses how scaling teams to support big data growth at Yelp can negatively impact deployment speed due to an exponential increase in the probability of failures as the number of developers increases. It proposes service-oriented architecture and focusing on mean time to recovery rather than just preventing failures as ways to mitigate these risks and maintain rapid iteration. Continuous delivery, reliable but not exhaustive testing, and treating all processes as distributed are also recommended to support scaling teams while preserving deployment speed.

Who let the robot out? - Building high quality software with Continuous Integ...
The document discusses the benefits of continuous integration (CI) for building high-quality software. It outlines the assumptions and realities of software development without CI. CI implements basic practices like not breaking the build and fixing issues quickly. The document then provides examples of tools and techniques for CI, including tests, code analysis, performance testing, documentation, and notifications. Implementing CI aims to deliver software that is on time, on budget, bug-free, maintainable, and high-quality.
Enterprise Workflows When You Aren't Enterprise
This document discusses enterprise workflows for software projects and provides recommendations for adopting more enterprise-like practices when resources are limited. It recommends establishing source control, continuous integration, managed environments with separate development, testing, and production stages, and a project management approach like modified waterfall, Scrum, or Kanban. Automating processes and deployments through tools can help achieve continuous deployment even on smaller projects.
Boston MeetUp 10.10
This document discusses automated testing, continuous integration, and continuous deployment. It highlights how automation can speed up testing from hours to minutes. Continuous integration involves testing every code change to catch bugs early. Continuous deployment uses automation to automatically release validated changes, making software releases a non-event. These practices allow organizations to deploy code much more frequently and with fewer failures.
Presentation_TDD
TDD is a process where test code is written before or alongside production code to drive the design and development of a project. It involves writing automated unit tests to force decoupling of dependencies and provide comprehensive testing. TDD helps think through requirements and design before coding to catch early bugs. It is an incremental process where tests are written and run continuously to build confidence with each new feature added. The key steps are to write a test, make it compile even if it fails, run it to failure, implement the code to pass the test, then refactor and repeat the process.
5 top pain points of test automation
Working in many companies as consultant, delivery manager or tech lead I have always seen the same mistakes made in test automation process. I could count successful cases on fingers of one hand. Sometimes people don’t understand the true value of test automation, sometimes just could not organize this process spending lots of money and time without any significant result. I want to share 5 top mistakes aggregated from whole my practice and solutions I recommend for them.
"I’ve heard you know infrastructure"
The document discusses the role and skills of a DevOps engineer. It notes that a DevOps engineer combines software engineering skills like coding with operations tasks like deploying, running, maintaining, monitoring and logging infrastructure. The document traces the evolution of a software developer who gains these additional operational skills to become a DevOps engineer. It emphasizes that DevOps engineers work to solve problems through skills like infrastructure as code and progressive learning. The document promotes leaving one's comfort zone and focusing on identifying real problems to solve.
Selenium as a trend
The document summarizes some key points about using Selenium for test automation:
1. Common traps to avoid include choosing Selenium solely based on trends, automating all tests without consideration for test types, and initiating automation late in the development cycle.
2. An example project story describes using Selenium with Java, Jenkins, and a page object pattern for tests of a PHP ecommerce site.
3. Issues that can arise include tests becoming difficult to maintain over time and new features breaking many existing tests. This leads to wasted effort and unhappy stakeholders.
TDD & Effective Software Development
This presentation explains WHY Test Driven Development matters and what are some of the infinite advantages of this great technique for programming a cleaner and higher quality code.
Test Driven Development and Automation
This document discusses test driven development (TDD) and automation for PHP projects. It covers what TDD is, why it should be done, where tests should run, who should adopt TDD, and why unit testing, code coverage, code sniffing and Selenium are important. It also discusses tools for PHP TDD like Xdebug, PHPUnit, PHP_CodeSniffer and IDEs. The document provides examples of writing test cases with the red-green-refactor process and integrating TDD into a build system with automated testing on every code change.

Bringing Quality Design Systems to Life with Storybook & Applitools
** Full webinar recording: https://youtu.be/R6WnEzlMHac **
Bringing design systems and component libraries to life can be a large, challenging process without the right tools. On top of that, maintaining a high level of quality throughout those systems brings its own challenge.
While there’s no shortage of ways to manually create a design system from scratch, doing so can be time consuming and can lead to technical debt when the system itself isn’t itself in a structure.
Storybook is a tool for developers that helps bring design systems and component libraries to life, providing structured tooling and a web dashboard. It gives those developers, and even designers, a way to focus on each individual component while being able to see the system from a higher perspective.
On top of that, Applitools is an automated Visual Testing solution that easily stacks right on top of Storybook with the Storybook Eyes SDK. With a single command, Applitools provides full test coverage for each component of your design system.
Join Developer Advocate, Colby Fayock, as he walks through:
How to take advantage of using Storybook to build scalable design systems
How Applitools makes automating the testing of those components easy
How to focus on building great experiences while automating quality checks with visual testing
Navigating the xDD Alphabet Soup
TDD, BDD, ATDD are all methodologies that enable incremental design that is suitable for Agile environments. It seems that every day a new xDD methodology is born with the promise to be better than what came before. Should you use behaviour-driven tests or plain old unit tests? Which methodology is better? And how exactly would it benefit the development life cycle?
In this session, Dror will help to sort out the various methodologies – explaining where they came from, the tools they use, and discussing how and when to use each one. Here we will once and for all answer the question as to whether or not there’s one “DD” to rule them all.
Unit testing patterns for concurrent code
Getting started with unit testing is not hard, the only problem is that most programs are more than a simple calculator with two parameters and a returns value that is easy to verify.
Writing unit tests for multi-threaded code is harder still.
Over the years I discovered useful patterns that helped me to test multi-threaded and asynchronous code and enabled the creation of deterministic, simple and robust unit tests.
Come learn how to test code that uses concurrency and parallelism – so that the excuses of not writing unit tests for such code would become as obsolete as a single core processors.

Unit tests & TDD
A session I did at Rupin Academic Center.
Part of modern software engineering course for bachelor degree in computer science.
Test Driven Development
The document discusses test-driven development (TDD). TDD involves writing tests before writing code to specify desired functionality, then writing just enough code to pass each test. This process of red-green-refactor evolves the system design through tests. TDD results in decoupled, well-designed code and provides benefits like confidence, documentation, and safe refactoring. The document also provides tips for writing better tests, such as keeping tests small, expressive, isolated, and automated.
Bdd - history and myths

Building unit tests correctly
This document discusses best practices for writing unit tests. It emphasizes that unit tests should be easy to understand, trustworthy, and robust. A good unit test only fails if a bug is introduced or requirements change. The document provides examples of well-written unit tests and discusses how to avoid common problems like fragile tests. It stresses the importance of testing only specified functionality, using isolation frameworks to mock dependencies, and not putting test logic in the test. Overall, the document promotes writing "clean tests" to avoid brittle tests and minimize maintenance overhead.

Similar to Visual Studio tricks every dot net developer should know
Debugging with visual studio beyond 'F5'
Debugging is part of any development process, but unfortunately it’s never planned or expected. On top of that, it’s rarely approached in a structured way, and while many modern IDEs have powerful debugging tools – most developers are not aware of how they can be used to reduce the time and pain of debugging. The whole act of debugging is done as an ad-hoc, time consuming activity, which is considered less interesting then developing new features or investigating the latest and greatest technology. But while there are many articles and productivity tools aimed at writing better code – faster, it seems as though it’s impossible to find resources that teach you how to effectively debug your code. In this lecture, we will discuss how to approach a debugging session, and show the latest power debugging capabilities Visual Studio has to offer. These will help you save time and pain by first understanding the problem and then fixing the bug that caused it.
Test-Driven Development In Action
This document provides an overview of test driven development (TDD), including what TDD is, an example unit test, the TDD process, benefits of TDD such as more maintainable code and fewer bugs, and resources for learning and practicing TDD such as books and training courses. TDD involves writing automated tests before implementation code to help ensure code quality and catch errors early. The process involves writing a test, seeing it fail, then writing just enough code to make it pass and refactoring as needed.
Amanda Cinnamon - Treat Your Code Like the Valuable Software It Is
2018 Women in Analytics Conference
https://www.womeninanalytics.org/
Data analysts create millions of lines of elegant, powerful code every year. However, because software development is not seen as their primary role, best practices of software engineering often fall to the wayside. Many data analysts are self-taught programmers who haven’t been exposed to tools like version control software, unit testing suites, and System Development Life Cycle (SDLC) processes. Popular software engineering concepts such as Don’t Repeat Yourself (DRY), design patterns, and modularization can vastly improve the quality and efficiency of analytics projects. This talk will provide a high-level introduction to these topics, and will focus on providing resources for additional learning.

That worked before
This document discusses the benefits of JUnit testing and test-driven development (TDD) for XPages applications. It encourages testing from both a user and developer perspective to ensure functionality and catch errors. The TDD mantra of writing a test first, making it fail, then fixing the code to pass the test is explained. An example of a test for currency conversion is provided. OpenNTF's JUnit plugin for XPages is recommended to allow testing. Benefits of TDD like catching errors quickly, understanding requirements, and relaxing because code is tested are outlined. The talk concludes by recommending a book on TDD by example.
Automated tests
There are many types of automatic tests, testing tools, libraries and approaches.
Automatic tests can save you a lot of stress but can also became a kind of a nightmare.
This presentation is an overview of what's available and how to use and not to use them to make them really useful.
Examples taken from PHP world. You might be surprised how many tools is available.
Joe Cisar - Everything I Know About TDD - Agile Midwest 2019
The document discusses test-driven development (TDD). TDD is a software development process where test cases are created to specify requirements before code is written to pass those tests. This ensures code meets requirements. Benefits of TDD include fewer bugs due to comprehensive testing, and ability to refactor code without breaking functionality. The document provides examples of different types of tests and outlines best practices for getting started with TDD.
iOS Test-Driven Development
Lightening Talk I gave at Inaka in April 2014.
I was in charge of investigating test-driven development for our iOS mobile team. Since I realized it was such a big concept, after having gathered enough information and having played with it enough, I decided to introduce my fellows on the topic by presenting it in a formal talk with slides. The aim was teaching them a different way of developing, which, for us, at that moment, was completely new and controversial.
Tdd
Test-driven development (TDD) is a software development process that relies on the repetition of short development cycles called red-green-refactor cycles. In TDD, tests are written before code to define desired functionality, and then code is written to pass those tests; this is followed by refactoring. The benefits of TDD include producing code that is robust, well-designed, and with fewer bugs due to comprehensive test coverage. While TDD requires discipline, it helps ensure code works as intended and allows refactoring with confidence that changes don't break existing functionality. Some potential vulnerabilities of TDD are that it may not prevent wrong solutions if requirements are unclear, can be difficult for UI or database-dependent programs
Agile Methodologies And Extreme Programming - Svetlin Nakov
1. Agile development and Extreme Programming (XP) are methodologies that focus on iterative development, collaboration, and adaptability.
2. XP consists of 12 key practices including simple design, test-driven development, pair programming, and small releases. It aims to improve quality, reduce risks, and adapt to changing requirements.
3. While XP works well for some projects and teams, its practices may not be suitable or flexible enough for all situations. Developers should understand the principles behind XP and tailor practices as needed for their specific projects.
Agile Methodologies And Extreme Programming
The document discusses Agile development and Extreme Programming (XP). It provides an overview of 12 key practices of XP, including planning games, small releases, test-driven development, pair programming, collective ownership, continuous integration and 40-hour work weeks. It also discusses how XP aims to solve software engineering problems through intensive teamwork, handling changes and staff turnover, and involving customers.
TDD and Simple Design Workshop - Session 1 - March 2019
The document discusses test-driven development (TDD) and simple design. It introduces TDD and some of its core practices, including test-driven development, simple design, refactoring, and pair programming. It provides an agenda for a workshop that will cover these topics over three sessions, including extreme programming (XP), the four elements of simple design, test doubles, outside-in TDD, and SOLID principles. The workshop aims to communicate best practices for using technical practices to succeed with agile development.
Effective TDD - Less is more
The document discusses techniques for making test-driven development (TDD) more enjoyable. It provides examples of conversations where a programmer asks if they can have quality assurance write tests, and whether tests are needed if code is working. The creator of TDD notes that tests should be written to reach a high level of confidence, not just to print "OK". Several rationalizations for not writing tests are debunked. The document advocates designing programs by writing tests first, and making initial tests fail on purpose in order to have the short-term goal of fixing them. This focuses effort and makes the process more fun. Less testing is needed than achieving 100% coverage; tests should be written when most useful, such as for new code
Usable Software Design
How to improve software design by using UX mindset, techniques and practices, given that the user of software design is the developer.
Continuous Integration
Continuous Integration (CI) is a development practice where developers integrate code changes daily with the main codebase. It helps reduce risks in software development by catching bugs early, improving team cohesion, and increasing code quality. To implement CI, teams should commit code changes frequently, have an automated build that runs tests on each change, and monitor build metrics to identify issues quickly. CI can help teams build better software faster and with more confidence.
Code Review
Code review is an inspection process where developers examine code samples to identify and fix defects. It helps ensure good code quality by allowing experienced developers to share knowledge with less experienced ones. Benefits include more stable products with fewer bugs due to improved code structure, standards and focus on new features rather than fixing issues. Issues that can arise include developers not following through on review comments, lack of buy-in, unrealistic expectations and peer fear. Various review types and tools can help address these issues.
A modern architecturereview–usingcodereviewtools-ver-3.5
For any project that is critical to the business, it’s important to do ‘Modern Architecture Reviews’. Being an architect is fun, you get to design the system, do ongoing code reviews, and play the bad ass. It is even more fun when using modern cool tools.
Software Testing Basic Concepts
The document discusses testing concepts such as code with tests vs without tests, test-oriented development, and different types of testing including unit testing, integration testing, and acceptance testing. It provides examples of test-driven development (TDD) and behavior-driven development (BDD) processes. The document also discusses tips for testing, including only testing what is necessary and identifying the appropriate types of testing for an application. Frameworks and tools for test automation and continuous integration are also mentioned.
Code smells and Other Malodorous Software Odors
This document discusses code smells, which are surface indications in source code that typically correspond to deeper problems in the system. It defines several common code smells such as duplicate code, large methods, magic numbers, dead code, and speculative code. The document provides explanations of these smells and recommendations for addressing them, such as extracting duplicated code into methods, breaking large classes into smaller focused classes, and avoiding checking in experimental code. It notes that code smells often arise from issues like haste, apathy, and ignorance when developing code.
Test Driven Development
TDD is a software development practice where tests are written before production code to define requirements. It follows three rules: 1) Write a test that fails without production code. 2) Write just enough production code to pass the test. 3) Refactor code without changing external behavior. This ensures code is properly tested and reduces bugs through frequent integration and refactoring enabled by the test suite. TDD results in testable, loosely coupled code and faster delivery times.

Unit testing patterns for concurrent code
Getting started with unit testing is not hard, the only problem is that most programs are more than a simple calculator with two parameters and a returns value that is easy to verify. Writing unit tests for multi-threaded code is harder still. Over the years I discovered useful patterns that helped me to test multi-threaded and asynchronous code and enabled the creation of deterministic, simple and robust unit tests. Come learn how to test code that uses concurrency and parallelism – so that the excuses of not writing unit tests for such code would become as obsolete as a single core processors.
The secret unit testing tools no one ever told you about
There are more to unit testing than using a unit testing framework - in order to succeed you want to use the right tools for the job. There are a few tools that almost no one talks about - some enabling creating of top-notch, robust unit tests. Some will help you run your tests better and faster. In this session I'll explain about the inevitable maintainability problems developers face when writing and maintaining huge unit testing suits and how unit level BDD, AutoMocking, and Continuous Execution can help take control over your tests.
From clever code to better code
Every software developer enjoys finding new and clever ways to solve problems. Writing code using his/her wits, intelligent and creativity. However, sometimes being too clever can lead to hard to track bugs, maintainability issues and impossible to understand code. Is all cleverly written code good code, or is it a problem just waiting to happen? In this session, I will show you real world examples of cleverly written code. And show you how we can use clean code principles, refactoring and design patterns, to transform that code from clever code to good code – one that your peers and future self would thank you for writing.

A software developer guide to working with aws
This document provides guidance for software developers working with AWS. It begins by recommending steps for getting started with AWS, including creating an AWS account and user, and not using the root account for security. It then discusses considerations for deciding on compute types, networking configurations, architecture for high availability, storage and database options, and how to test services locally before deploying to AWS. The document demonstrates calling AWS services from code and provides resources for learning more about AWS services and costs.

The role of the architect in agile
In Agile development, architects still play an important role by setting constraints and principles to provide guidance and boundaries for development teams. While Agile values working software over documentation, architects can document architecture decisions and provide guidance through code examples. On Agile teams, the architect acts as an owner who facilitates architectural decisions, explores new technologies, and evolves the architecture over time based on learnings. The architect also helps align development across teams when needed.
Harnessing the power of aws using dot net core
In the past AWS and C# seemed to belong to two different eco-systems. One was a leading cloud platform while the other a widely used, powerful programming platform.
Does it mean that a developer that needs to provide a solution in the cloud must choose between the two? Not anymore.
In this talk, I will show how to write C# code that runs in a dockerized container in the cloud or as an AWS Lambda and harness, the popular AWS services.
Developing multi-platform microservices using .NET core
In the past, C# developers’ could only look in envy as the world moved to container based micro services and cloud deployment – until now.
With the new ASP.NET Core a C# developer can write REST based microservices using the latest and greatest Visual Studio and deploy them in a different OS - or the cloud using Docker, quickly and effortlessly.

C++ Unit testing - the good, the bad & the ugly
C++ is a powerful language when used by a seasoned developer. It is being used everywhere from operating systems and compilers to cross platform mobile apps development.
But this power comes with a cost - C++ programming is not simple nor easy – with memory leaks, stack overflows and strange exceptions, a software developer needs all of the power he can use.
By harnessing the power of unit tests a software developer can find defects quickly, avoid regression and speed up development time.
In this talk I’ll show how to use the right unit testing tools and practices available that will help you get your C++ code under control and even test legacy code which no one ever want to touch.
Working with c++ legacy code
The document discusses strategies for working with legacy C++ code, including gaining control over legacy code through iterative refactoring while ensuring existing functionality is maintained. It emphasizes learning what the code does, making sure it continues functioning properly, and making gradual improvements. Specific techniques mentioned include writing tests, creating fake objects to inject into code under test instead of real dependencies, and using templates or friendship to fake classes that are otherwise difficult to mock.

Electronics 101 for software developers
These days it seems as if everybody talks about the internet of things (IoT). With a cheap Arduino, Raspberry PI (or another microcontroller) every developer has the power to control the real world.
Suddenly confronted with resistors, digital inputs, analog interfaces and a weird bread board full of holes – a developer is reminded that the world of hardware can be confusing and sometimes downright frustrating.
Who’s afraid of WinDbg
This document introduces WinDbg, a debugger tool that can be used for post mortem crash analysis, memory leak detection, and deadlock discovery. It discusses how to load crash dumps and symbols, and provides an overview of basic commands like listing processes and threads. Crash analysis commands for .NET like !analyze, !printexception, and !clrstack are presented. Commands for investigating memory issues like !dumpheap and !gcroot are also highlighted. The document concludes with discussing deadlock detection using commands like !dlk and !mwaits.
Designing with tests
Unit tests are great, they help a developer gain control over his code and catch bugs and regression issues.
Test Driven Development is a methodology that uses unit tests but it's not about writing unit tests - in fact the tests are only a design tool.
TDD is a methodology that solves problems in an iterative way, it's about emergent design that creates a maintainable solution.
In this session I'll talk about common mistakes and misconceptions, how to benefit from TDD and show how to design your code using unit tests.

Building unit tests correctly with visual studio 2013
Unit testing is now considered a mainstream practice, but that does not mean it is as common, pervasive or as well understood as it could or should be. Many programmers struggle with the quality of their tests and with the focus of their code. In this session we’ll learn how to write good unit testing code.
Writing clean code in C# and .NET
Maintaining the product is one (if not the most) expensive area of the overall product costs. Writing clean code can significantly lower these costs, making it more efficient during the initial development and results in more stable code. In this session participants will learn how to apply C# techniques in order to improve the efficiency, readability, testability and extensibility of code.
Using FakeIteasy
Using FakeItEasy allows creating fake objects to use in tests. It is a .NET dynamic fake framework that provides a fluent interface to define fake object behavior and assertions. FakeItEasy fakes objects by creating derived classes, so only virtual, abstract, and interface methods can be faked. It handles default behavior and parameter handling to reduce test code. Dependency injection helps pass fake objects to production code under test.
