A simple collection of small JavaScript exercises to practice software testing.
This is the side material for my workshop on software testing for the Microsoft Reactor Stockholm sessions for beginners. It's a collection of small JavaScript exercises to practice software testing. The activities are designed to be simple and easy to understand so you can focus on the testing part.
You can check my small slide presentation here (in English). There are not many slides because the session was a hands-on workshop, so I recommend you try the exercises yourself because the slides will only provide some context on concepts and initial understanding.
You'll have to install Node.js version 18 or later since we'll be using the experimental test runner. I won't show how this is installed here because there's plenty of content about it on the Internet.
Some exercises will not need any external dependencies, and some will be run with test runners aside from Node's native one (like Jest), so you'll need to run npm install inside those folders so the test runner can be executed.
Your journey starts in this branch.
The repository is divided into exercise folders; each folder has a number in front to show which order they should be done. They go from the most basic to more advanced examples as you progress.
Be aware that, in some folders, there's also a
package.json, if this is the case, runnpm installinside the directory to install the packages
- Assertions: Exercises in this folder will show how to assert different types of expressions; it's meant to be executed with the default node
assertlibrary - Test suites: Exercises here will show how to use test grouping to make tests easier to read, for now, you'll use only Node.js native test runner; the tests can be executed with
node --test <file-name> - Test runners: Here you'll need to run
npm install jestinside de folder to install the Jest test runner. All subsequent testing can be done with thenpm testcommand - Test doubles: From now on, we'll be using Jest as the test runner. This directory has some more advanced testing cases to teach the use of test doubles
- TDD: This directory contains a simple code, but the idea is to get the descriptions of functions and features you should create using the TDD approach in the challenge docs.
The solved exercises can be seen in the resolved branch.
Challenges are sets of questions that will defy your knowledge, they don't have an answer in the resolved branch which means you'll have to do it by yourself! Good luck.
If you want to contribute with more exercises and add more tests, feel free to do so opening a PR with your new test files, just make sure that they're following the same code conventions as the other files.
