Beginners Guide: Test Driven Development (TDD) with Mocha and Chai (Using Node Js)

[devpatel58]

Today, we’ll talk about the process of conducting Test Driven Development with Mocha and Chai in Node JS. Let’s get started.

What is Test Driven Development (TDD)?

It is a process where you write your unit test first, watch it fail, and then implement the necessary code to the module you’re creating until the test passes. That’s it!

How should it be done?

• Unit tests should be specific and should test particular components and algorithms of the code you wish to test
• The data used in the testing should be static or variable and not shouldn’t be subject to change from external API calls. For example, a specific output should be expected

After writing your unit tests and implementing the code for them, if they all pass, you’re done!
Tests are one of the main steps of the Software Development Life Cycle (SDLC) before the end product can be deployed and used.
Different kinds of testing are done on the product to ensure quality and confidence, like Unit Testing. There are popular frameworks that can test scripts, maintain test suites, and populate test results.
