Code review at large scale
When you work in a small collocated team many engineering practices and approaches are relatively easy to use and adapt. In large project with many teams working on the same product this task is not so simple. I want to share experience report in implementing Code Review practice in big product development team (more than 150 people, 10+ feature teams). In this talk we will review what approaches works in such setup and what don’t work, what tools and additional practices are needed to support Code Review and make it more effective, what difficulties and blockers will you probably see in the real life cases, what useful metrics could be produced by this practice.
The Essentials Of Test Driven Development
Test Driven Development is the fastest method to get software onto the market. Being one of the most used methods in the present business world, here is why the method is essential.
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.
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.
Helping Programmers Write Better Tests
The document discusses ways to help programmers write better tests, such as starting a quality culture, running TDD/refactoring competitions, joining code reviews, and pairing/mob programming. It notes common problems with tests like unclear names, complex setups, and lack of teardown. Testers can help by focusing tests on one thing, using clear data, and writing tests a customer would understand. Challenges include applying skills to real code and some programmers not wanting to pair.
TDD- Test Driven Development
Test Driven Development (TDD) is a technique where tests are written before code to define desired functionality, with the cycle of writing a test, seeing it fail, then writing code to pass the test while refactoring code for quality. TDD ensures requirements are met, forces clean code principles like isolated and decoupled components, and leads to improved test coverage and faster debugging. For effective TDD, tests should be clean, self-documented, have single asserts, run fast, be independent, and have boolean outputs. While it may initially slow development time, TDD provides long term benefits.
Continuous delivery test strategies
A high level introduction why and how to test within in a continuous delivery or continuous integration process
XP Injection
Nikolay Alimenkou and Aleksey Solntsev will show how to migrate from Ant project to Maven2 project and start using full power of XP engineering practices: CI, TDD, refactoring.

Code Review
This document discusses best practices for code reviews. It provides guidelines for conducting effective code reviews, including reviewing no more than 400 lines of code at a time and taking 60-90 minutes for reviews. It also lists fundamentals to check like warnings, unused code, and naming conventions. Popular code review tools are mentioned. Conducting code reviews can improve code quality, catch bugs earlier, share knowledge, and mentor junior developers.
Test Driven Development - Overview and Adoption
Test-driven development (TDD) is a software development technique where unit tests are written before code to define desired functionality. Writing tests first helps produce code with better design, lower maintenance costs, and fewer bugs. Key principles of TDD include writing code only to pass failing tests and eliminating duplication. Benefits include better test coverage, easier refactoring, and preventing regressions. TDD helps developers act as users to define behavior through interactions between system components.
When you get lost in api testing #ForumPHP
If you are not writing tests yet, you should start. Tests will improve the quality of your code, reduce bugs and probably force you to think more about design and quality. Actually, the hardest thing is to start and figure out which type of tests to write.
So you start researching and you find a lot of different materials and get even more confused.Even when you decide what type of tests to use, it can be hard to decide how to test some specific logic in your app.
Don’t give up! We have some tips we learned along the way that will hopefully make your life easier. In this talk you will hear about different test types and when to use them. We’ll also show some tools for checking quality of your test.
Funny stories and anti-patterns from DevOps landscape
During last several years DevOps became strong buzzword used almost in every project, team and company. But almost everywhere it is used in very funny and strange context. For example, existing ops guys are renamed to DevOps just to sell them to the client for more money. Or DevOps is used as new job title for some magically powerful person who is able to operate cloud environment and modern infrastructure related tools, leading team of old school ops and participating in management meetings. In this talk I’m going to review all different anti-patterns and bad practices in DevOps landscape using stories from my personal experience as Delivery Manager and independent consultant.
ReportWriterCertification
The document contains 5 practice questions for an expert report writer certification. The questions cover topics like the limit on view components that can be added to a view in View Editor 2.0, how to pass data between main and sub-views, syntax that would cause a SQL error, calculating total fees and disbursements for a report, and common areas that cause inaccurate report line items. A bonus question asks about considerations for the counter used in an AfterSelect loop to delete rows from the result set.
Myths and reality about software testing
Most of the people might say that software test engineers do not write code. Testers normally need completely different skill set which could be a mix of Java, C, Ruby, and Python.
That is not all you require to be a successful tester. A tester requires having a good knowledge of the software manuals and automation tools.
Depending on the complexity of a project, a software testing engineer may write more complicated code than the developer.

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.
Agile Testing 20021015
This document discusses agile testing and its principles. It defines agile testing as testing practices that follow the agile manifesto and treat development as the customer of testing. The key principles of agile testing are that individuals and interactions are valued over processes, working software is valued over documentation, and responding to change is valued over following a plan. It also discusses specific agile development methodologies like extreme programming and the role of testing in agile projects.
Developer + tester = quality++
With Agile adoption many things have changed in quality assurance and tester role. Ourdays the whole team is responsible for product quality. But not so many people understand how such high level approaches work in practice, how developer interacts with tester, what stages each task passes on the way from requirements specification to customer acceptance, who is doing what at each stage.
I have met only few teams, where developer and tester work closely together on a daily basis. Some projects try to same money on developer's time, others try to have independent testing team without influence from developers side. Developers also don't understad how tester could help them in practice. But this pair is able to significantly improve product quality and avoid many common issues.
In this talk we will cover motivation behind pair work of develoeper and tester, concrete practices and approaches at different stages, and advantages that both sides could achieve from such work style.
Test-Driven Development Reference Card
This document discusses Test-Driven Development (TDD). It defines TDD as writing unit tests before writing any production code. TDD helps ensure code is consistently refactored for better design. The document outlines the TDD process of writing a test, seeing it fail, writing code to pass the test, then refactoring. It discusses using TDD with legacy code by refactoring code to be testable. Sample unit tests are provided to demonstrate testing default constructor values. Benefits of TDD include better code design, earlier defect detection, and fewer defects in production releases.

TDD for Testers Workshop
This document discusses test driven development (TDD) for testers. It provides an overview of TDD, including writing tests before code, different types of tests, and the testing roles of developers versus testers. Developers are said to be "solution space" people who write unit and integration tests to drive code design, while testers are "problem space" people who focus on exploring potential problems and edge cases without limitations. Both developers and testers should work to avoid redundant testing and place the right types of tests in the right locations.
Automation and Technical Debt
Technical debt can accumulate when teams prioritize quickly delivering features over maintaining quality. This leads to slower development and more bugs over time. Automation helps reveal technical debt through continuous integration tests, code inspections, and trend analysis. As teams automate their build, deployment, and testing processes, they often discover previously unknown issues. Both direct testing and the learning from automation efforts help teams understand and address technical debt. Managing technical debt through automation provides benefits at both the team and enterprise levels.
Code review in practice
This document provides an overview of code review practices. It discusses why code review is important to improve code quality, readability and maintainability. It describes different types of code review including over-the-shoulder, pair programming, automated and various time-based methods. Tools for facilitating code review are also presented, such as Review Board, Gerrit, Fisheye/Crucible and SmartBear CodeCollaborator. The goal of the document is to educate about best practices for conducting code reviews.
How to successfully grow a code review culture
As a team grows, code ownership is distributed. Code review becomes increasingly important to support the maintainability of complex codebases. An effective code base is on that can be worked on collaboratively by a team.
In this talk we'll discuss how to introduce a successful code review culture to your development team that will foster the idea of shared ownership. This in turn will result in a happy and healthy code base.

Code Review tool for personal effectiveness and waste analysis
Usually it is hard to analyze personal effectiveness and detect wastes in development process because developer’s work decomposition is not transparent and available for analysis. As a good sample of ineffective process imagine developer, who spends 1 day on task implementation and then reimplements it several times according to code review notes during next 2 days. Or another developer, who is waiting for code review during 2 days, switching context to other tasks, finally gets notes and switches back to initial task, trying to refresh all details in his head. And so on and so forth…
Code review tool usage helps to aggregate lots of useful information about any code change at any stage (static analysis, code review, rework, acceptance, integration into main branch). In this talk I’m going to demontrate how this information could be used for detailed analysis of development effectiveness and wastes detection. Based on mentioned analysis you could implement many improvements for your development process and then measure their success.

What is Unit Testing
This document discusses unit testing and its benefits. It begins by outlining some questions about unit testing, then compares unit tests to UI tests. Unit tests are faster, test individual functions, and make code easier to change and refactor. The document provides an example of unit testing a password validation function in PHP Laravel. It discusses that while test coverage is a quality metric, high coverage alone does not guarantee high quality. It argues that internal quality through practices like unit testing does not require tradeoffs with development speed, and can actually improve productivity by reducing unnecessary tasks and lead time. Maintaining clean code through practices like unit testing is important for both quality and speed.
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.

Test driven development
Unit testing involves writing code to test individual units or components in isolation to determine if they are functioning as expected. Writing tests first, before production code (test-driven development or TDD) can lead to higher quality code, easier debugging, and increased confidence in changes. The TDD process involves writing a failing test, then code to pass the test, and refactoring code as needed. To apply TDD effectively, tests should focus on logical code, avoid duplications, and isolate dependencies to keep tests simple and maintainable. Both server-side and client-side code need testing, focusing on things like business rules, view models, repositories, and UI logic.
Test-Driven Development
Test-driven development involves writing unit tests before code to validate functionality. Unit tests help manage changes by continuously validating code correctness and allowing code to be changed safely. While some myths exist around unit testing, it can save significant time compared to finding and fixing bugs later. Setting up projects with separate code and test folders allows tests to run independently.

The document discusses various quality practices in Agile, including test-first development, acceptance test-driven development, continuous integration, and defining "done". It provides details on processes like writing tests before code, executing tests with each build, and criteria for completing stories. An experiment found that while test-first development took more time initially, it resulted in higher quality code and more test cases compared to test-last development. Continuous integration helps keep all code integrated through frequent builds and supports releasing high quality code.

Test driven development
Test-driven development (TDD) is a software development process where unit tests are written before code to define desired functionality through a series of short cycles: write a test, see it fail, write minimum code for it to pass, refactor code. Key benefits include more modular/extensible code, catching defects early, and increased confidence through thorough test coverage. Shortcomings include lack of full functional testing and risk of false sense of security if tests have same blind spots as code.

Best pratice
The document discusses several important topics for software development including unit testing, clean coding principles, design patterns, and useful development tools. It emphasizes that tests are important for preventing bugs and should be included in all projects. Clean coding principles like DRY, KISS and SRP help produce code that is easier to read, change and maintain. Design patterns provide solutions to common problems and a shared vocabulary for developers. Useful tools include IDEs, version control systems, code analysis tools and text editors which can help programmers work more efficiently if used properly.
xUnit and TDD: Why and How in Enterprise Software, August 2012
“A comprehensive suite of JUnit tests is one of the most import aspects of a software project because it reduces bugs, facilitates adding new developers, and enables refactoring and performance tuning with confidence. Test-driven development (TDD) is the best way to build a suite of tests. And the Dependent Object Framework is the best way to test against database objects.” This presentation covers the benefits of TDD along with practical advice on how to implement TDD in complex projects.

Understanding Unit Testing
Unit testing is a method to test individual units of source code to determine if they are fit for use. A unit is the smallest testable part of an application. Unit tests are created by programmers during development. Test-driven development uses tests to drive the design by writing a failing test first, then code to pass the test, and refactoring the code. Unit tests should be isolated, repeatable, fast, self-documenting, and use techniques like dependency injection and mocking dependencies. Benefits of unit testing include instant feedback, promoting modularity, acting as a safety net for changes, and providing documentation.
Clean code: understanding Boundaries and Unit Tests
This document discusses principles of clean code and unit testing. It covers boundaries when using third-party code, such as writing learning tests to understand external APIs. Tests should be kept clean like production code so they remain maintainable as the code evolves. Tests that are readable, use the BUILD-OPERATE-CHECK pattern, and have one assertion per test help achieve this. The document also advocates writing tests before production code according to the Three Laws of TDD and principles of FAST tests.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

- 5. Should you be your own judge? Do you really need to write a code to test a code when you already have a team dedicated to checking for problems?
- 6. Unit Test A unit test is code that tests as small a piece of functionality (the unit) as possible, in isolation. Tests ensure: 1. The code meets expectations and specifications: Does what it says it should do. 2. The code continues to meet expectations over time: Avoiding regression. 6
- 7. 7 we don’t do testing for production, we make code predictable, scalable & changeable tackle the defects in user workflow, in the full spectrum of application functionality
- 8. ● Problem solving ● Writing code ● Thinking & handling edge cases
- 9. So, what? Why it matters? 9
- 10. Confidence is a key 10 Changing already tested code is both risky and costly. If we have unit tests in place, then we can proceed for refactoring confidently.
- 11. Testable code 11 Trouble writing tests? The problem's not in your test suite. It's in your code.
