  • How to Confidently Write Unit Tests using React Testing Library
    7 projects | | 1 Dec 2022
    We cannot only use the testing library alone, but we also need to install Jest which exposes extensively used global expect function and other things which help to make assertions in our test cases.
  • How I go with react native in late 2022
    33 projects | | 27 Nov 2022
    There's nothing better than jest and testing-library/react-native in react-native. these tools are suitable for unit and integration tests and they have great community support, utils, and helper functions.
  • Adding Tests for ESM using Jest framework
    2 projects | | 25 Nov 2022
    Jest is a testing framework for Javascript projects. It ensures that the implemented core functionality of the codebase is not prone to errors by allowing developers to write convenient tests.

    4 projects | | 20 Nov 2022
    However, while running the tests using jest would result in a pass, the expectations would actually fail and the failure result would show up after the tests have already ended. I was confused as to why was happening for a while. Eventually, I noticed this in the file:
  • Auto-run Tests: Test Via Continuous Integration
    2 projects | | 17 Nov 2022
    There was another repo I tried to add test for, and it uses the same setup as mine. It uses JavaScript and achieve CI via GitHub Action, except that it also run test for version 14.x and 16.x of Node.js. Given both repo use Jest for testing, It's pretty easy to write test for the repo. I needed to spend time to understand the code and then run test coverage and see the existing tests to see what's needed to be done.
  • Making sure izyum is fresh

    Two testing engines are usually used for testing purposes in the ECMAScript world which are jest and mocha. I had previous experience with both of them and to be honest I don't see big differences between them on the basic level. I decided to go with it just because it is more popular and I did use it with typescript before so I did know it had good types of support.
  • Conditional Logging to the JavaScript Console
    4 projects | | 14 Nov 2022
    The console created by createDebugConsole will not be active in unit tests, so you won't be able to use it to prevent logging in your test environment. If you use jest you can silence console methods with the jest CLI.

  • JavaScript testing with Jest
    3 projects | | 13 Nov 2022
    I chose Jest, as it is one of the most used testing frameworks for JavaScript and most of my tool's logic is written in JS. It was developed by Facebook and is open-source. Jest also has CLI option for checking coverage which is very great, it shows which lines of code have been tested and not and prints a beautiful report.
