JS Unit Testing

ILIAS is using Mocha as test framework for Javascript unit tests. The esm extension allows to use ES6 modules seamlessly. Chai is being used as assertion library.

Install

(not necessary as long as we keep npm modules in our git repo)

> npm i --save-dev mocha
> npm i --save-dev esm
> npm i --save-dev chai

package.json changes

{
  ...
  "scripts": {
    "test": "mocha --require esm"
  },
  ...
}

Run tests

> npm test

Example

Your tests should be located in a subdirectory test.

See js-unit-test-example/test/component.test.js.
