This document discusses the importance of testing code through various methods like unit tests, integration tests, and acceptance tests. It recommends that developers write tests for their code, run tests frequently during development and before each commit. It also advises measuring code coverage to identify parts of the code that are not adequately tested so those risks can be addressed. Regular testing provides confidence in the code, helps with collaboration, and ensures code quality.

Developers on test
Testing is important for project quality and reliability. Unit tests check individual code units for correct functionality, are fast and independent. Behavior-driven development (BDD) applies business needs through scenarios defined in Gherkin. Test doubles replace code to independently test objects like dummies, fakes, stubs and mocks. Integration tests check connections between components while acceptance tests check overall project behavior from the user perspective, ensuring expected functionality but are slower and require more maintenance.

As the Salesforce1 World Tour moves to London on May 22nd 2014, Force.com MVP's Chris Lewis and Simon Lawrence present the 15:00 Developer Stage Session on Testing Best Practices for the Salesforce.com Platform.
TDD
Test Driven Development (TDD) is an approach where test cases are written before functional code to think about how components should work. It follows the principles of Red-Green-Refactor, writing a test (Red), then the functional code to pass the test (Green), then refactoring the code. TDD leads to well-designed, loosely coupled code with full test coverage that is easy to maintain and refactor with confidence in changes. While it may initially take longer, TDD finds bugs earlier and reduces bugs by 45-90%, saving significant time versus fixing issues late in development.
Testing 101: Three Rules for Testing at Ombu Labs
In this presentation we talk about three rules that we follow every week to deliver high quality code. We prefer to write tests in this order: Integration tests first, unit tests later.
We don't do TDD religiously but it is a good idea when you're facing a very complex problem.
Think about your code as a black box and think about all the possible inputs and outputs, all the possible paths that a user might take, all the possible ranges that the user may enter.
Don't test only the happy path, keep in mind the odd cases.

Agile Engineering Best Practices by Richard Cheng
By Richard Cheng, Certified Scrum Trainer and Training Business Unit Lead, Excella Consulting
21st Century IT development requires building quality into our development practices yet many software teams fail to implement technical practices that are necessary for long term success. Practices like automated builds, automated tests, automated deployments, continuous integration, and continuous delivery are now considered essential for the success of any software development project. Without these practices, the quality of software goes downhill and teams can no longer sustain their initial high levels of productivity.
However, understanding and implementing the practices can seem daunting. This session presents an easy to understand roadmap for implementing engineering best practices for non-technical audiences.
Though this topic is about engineering best practices, attendees do not have to be technical to get value from this session. The session gives a non-technical look at a technical concept and is great for any person in the organization managing, working with, or working on IT teams/programs.

The document discusses Test-Driven Development (TDD). Some key points:
- TDD involves writing automated tests before writing code to ensure tests fail initially and then passing the tests by writing just enough code. This prevents writing extra code and helps design code structure.
- TDD provides benefits like confidence in code quality, catching errors early, and giving feedback on changes. Unit tests should initially fail, test individual components, and not be for finding bugs which is done through manual testing.
- The basic TDD process is to create a failing test, write just enough code to pass the test, refactor code, and repeat the process for each new feature or change. This helps integrate TDD into
Fault tolerance - look, it's simple!
The ability of a system to respond gracefully to an unexpected hardware or software failure.
There are many levels of fault tolerance, the lowest being the ability to continue operation in the event of a power failure. Many fault-tolerant computer systems mirror all operations -- that is, every operation is performed on two or more duplicate systems, so if one fails the other can take over.
In most cases it could be achieved by redundancy in application design and set of patterns and approaches to software design.

Examples of good practices include writing unit tests with code, focusing prototypes on solving problems, getting customer feedback, and testing at production scale. Examples of bad practices include writing unit tests long after code, not isolating dependencies, failing to use the product as intended, and load testing in different configurations than production. The overall message is that testing effectiveness depends on matching the test to the
Software Engineering Culture - Improve Code Quality
It's usually not enough time for improving comfort of code writing and product monitoring. But this is an important thing for making software products with high quality. IT society even made awesome tools for making our life easier and culture of software engineering continue growing.
An Introduction to Unit Testing
Unit testing involves writing automated tests to test code. Automated tests are repeatable and help catch bugs before deploying code. The main benefits of unit testing are that it allows developers to test code frequently and in less time, catch bugs before deploying, deploy with confidence, reduce bugs in production, and refactor code with confidence.
There are different types of tests including unit tests, integration tests, and end-to-end tests. Unit tests isolate a unit of code without external dependencies and execute fast but provide less confidence. Integration tests involve external dependencies and provide more confidence but take longer. End-to-end tests drive the application through its UI and provide great confidence but are slow.

Historias para recordar
En las Olimpiadas Especiales de Seattle, nueve participantes con discapacidad mental compitieron en los 100 metros. Un niño tropezó y comenzó a llorar, pero los otros ocho corredores se detuvieron, regresaron y lo ayudaron a levantarse, caminando juntos hasta la línea de llegada para apoyarlo. El estadio entero los aplaudió por su muestra de compañerismo y ayuda mutua, enseñando que lo más importante es apoyarnos los unos a los otros.

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.
Testing As A Bottleneck - How Testing Slows Down Modern Development Processes...
We often claim the purpose of testing is to verify that software meets a desired level of quality. Frequently, the term “testing” is associated with checking for functional correctness. However, in large, complex software systems with an established user-base, it is also important to verify system constraints such as backward compatibility, reliability, security, accessibility, usability. Kim Herzig from Microsoft explores these issues with the latest webinar on test Huddle.
Understand release engineering
Release engineering involves managing the delivery of high quality software releases through processes like release planning, branch management, building, testing, and source code control. It aims to make releases predictable and of high quality by facilitating activities such as compiling code, verifying functionality, controlling branching/merging of codelines, and following best practices.

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
This document discusses definitions, principles, and best practices of test-driven development (TDD). It defines different types of TDD like test-oriented development, test-driven design, acceptance TDD, and developer TDD. The key principles of TDD discussed are red-green-refactor cycles, writing tests before code, and values like improved design, code quality, and maintenance. Guidelines around trustworthy, maintainable and readable unit tests are also provided.
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.
Quality Loopback
The ability to deliver software to production speedily and reliably is critical to supporting a disruptive business landscape and covering implementation gaps. A key factor inhibiting this is testing. DevOps practices encourage shifting left, i.e., testing more during development using unit and component test rather than with QA using end-to-end tests. However, unit and component testing lack functional coverage that may exist in QA end-to-end tests. Shifting left with a domain focus may lead to component and unit tests that don't just guarantee that the software is built right but also that the right software is build.
Test Driven Development
The document outlines an upcoming programming workshop that will cover various JetBrains IDEs like PyCharm, IntelliJ IDEA, and PhpStorm. It then discusses Test Driven Development (TDD), including what TDD is, the development cycle used in TDD, and benefits like encouraging simple designs and confidence. Different types of software tests are also listed like unit tests, integration tests, acceptance tests, and others. Specific testing techniques like unit testing, integration testing using bottom-up and top-down approaches, and acceptance testing are then explained at a high level. Finally, some important notes on testing like trusting tests and prioritizing maintainability are provided.
Requirements Based Testing
The document discusses various software failures and errors through case studies such as Disney's Lion King software issue in 1994-1995, the Intel Pentium Floating-Point Division Bug in 1994, the NASA Mars Polar Lander crash in 1999, and the Patriot Missile Defense System failure in 1991. It then covers testing definitions, principles, and the role of testing in the software development lifecycle through topics like requirements testing, ambiguity reviews, and change control tools. The goal of testing is to increase the probability that software will behave correctly under all circumstances by meeting requirements through systematic testing activities.

It outlines 30 tips for writing tests, including writing tests before code, treating tests like code, minimizing asserts per test, using data providers, and allocating time for testing in estimates. Testing helps catch bugs, improve code quality, and ensure stability. The document emphasizes that automated testing is key and should test everything that could break an app.
Empirically Detecting False Test Alarms Using Association Rules @ ICSE 2015
Applying code changes to software systems and testing these code changes can be a complex task that involves many different types of software testing strategies, e.g. system and integration tests. However, not all test failures reported during code integration are hinting towards code defects. Testing large systems such as the Microsoft Windows operating system requires complex test infrastructures, which may lead to test failures caused by faulty tests and test infrastructure issues. Such false test alarms are particular annoying as they raise engineer attention and require manual inspection without providing any benefit. The goal of this work is to use empirical data to minimize the number of false test alarms reported during system and integration testing. To achieve this goal, we use association rule learning to identify patterns among failing test steps that are typically for false test alarms and can be used to automatically classify them. A successful classification of false test alarms is particularly valuable for the product teams as manual test failure inspection is an expensive and time-consuming process that not only costs engineering time and money but also slows down product development. We evaluating our approach on system and integration tests executed during Windows 8.1 and Microsoft Dynamics AX development. Performing more than 10,000 classifications for each product, our model shows a mean precision between 0.85 and 0.90 predicting between 34% and 48% of all false test alarms.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
