Top 23 Testing Open-Source Projects

• puppeteer

  33 69,024 9.2 TypeScript

  Headless Chrome Node.js API

  Project mention: Programmatically audit with Lighthouse and performance budgets | dev.to | 2021-03-02

  The example implementation uses Puppeteer, as this would allow us to interact and navigate before beginning the audit. The audit method returns the results including metrics that have not met the budget requirements, allowing us to fail a build and/or report metrics.

• storybook

  19 58,775 10.0 TypeScript

  Project mention: Breaking down a very large re-design project. What's your process? | reddit.com/r/UI_Design | 2021-03-02

  Since you've already done the work to create a design system, I would encourage the client to allocate engineering resources towards implementing your design system in a generalized way as a component library, even going so far as to create some component documentation like storybook. This way, the redesign of each flow will be quick, painless, and without need for pixel perfect designs. This should make some redesigns so obvious they won't need your intervention. Others might only need wireframes, and only a few should require a full design. It will also enforce good design with code, even after you move on, by making it hard to break rules and easy for lazy engineers to use good design rather than building their own creations.

• jest

  16 34,306 9.5 TypeScript

  Delightful JavaScript Testing.

  Project mention: How do you test a design system? | dev.to | 2021-02-25

  In the past I've worked on React component libraries and used tools like Storybook to develop them. Testing these is pretty easy - I tend to use mostly react-testing-library and jest.

• PHPT

  11 29,483 10.0 C

  The PHP Interpreter

  Project mention: Web based application | reddit.com/r/webdev | 2021-02-25

  The PHP manual at www.php.net tip, as you are learning and you see a function you are not sure what it will do, try just adding the function after that url. ie. What does sprintf() do? www.php.net/sprintf will take you to the page for it, and most have very good information with examples

  Simple JavaScript testing framework for browsers and node.js

  Project mention: Mobile e2e tests using WebdriverIO and Appium | dev.to | 2021-02-28

  So this is new for me. I normally write posts explaining things I've been doing in a daily basis for many years. However, I started working for a new client somethings like a month ago. I'll talk about the team organization at some point, in another post, because I really like how these guys work. However, this post is about end-to-end tests. In the team I'm now taking part of, everyone is responsible for writing e2e tests for iOS/Android/Web. I've never done that before, I have to confess. I've done Unit tests many many times, but I've never written so many integration tests. Appium, WebdriverIO and Jasmine are the tools this team has chosen to write these tests, and for good reasons. Let's first distinguish briefly among the different types of automated tests. Particularly between e2e and unit tests.

  Project mention: How To Find Performance Issues Before Deploying | reddit.com/r/sre | 2020-12-29

  Not OP, but that is the idea. I use this tool for it, as it is dead-simple to get running and fairly configurable: https://github.com/buger/goreplay

• Mockito

  1 11,530 8.8 Java

  Most popular Mocking framework for unit tests written in Java

  Project mention: Prefer Fakes Over Mocks | dev.to | 2020-10-13

  According to the original definitions introduced by Gerard Meszaros, a mock is a very specific type of substitutes which is used to verify interactions between the system under test and its dependencies. Nowadays, however, the distinction has become a bit blurry, as this term is commonly used to refer to a broader class of objects created with frameworks such as Moq, Mockito, Jest, and others.
