Testing - Mini

Topics:

• Mocha
• Chai
• Sinon
• Assert
• Expect

Project Description

• The objective is to get you exposed to unit testing with Mocha/Chai and Sinon.
• You will be writing tests for the code inside of src/app.js.

Initialize Project

• cd into repo and run yarn install or npm install

Pre Set Up

• You'll notice we have two directories src and test. Inside of src/app.js & src/functions.js you'll see all the code that we want to test, being exported out of the given files.
• Go ahead and run yarn test or npm test and it will execute the testing suites.
• We have installed a watch command that will re run on save.

Steps for implementing Tests

• Step 1: You have a broken test suite already, go ahead and change each test assertion such that it passes the expected test. Everything begins on line 14 inside of tests/types.test.js begin there.
• Step 2: After you have all of your tests passing inside of types.test.js you can start testing the functions found in the src/functions.js file.
  • Write your testing code for these functions inside of tests/functions.test.js
