How to write a unit test suite with ember.js?

@lizzie 

In Ember.js, unit tests are typically written using the QUnit testing framework. To write a unit test suite in Ember.js, follow the steps below:

1. Install QUnit and ember-qunit: If you haven't already, install QUnit and ember-qunit by running the following commands in your Ember.js project directory:

1
2

npm install --save-dev qunit
npm install --save-dev ember-qunit

1. Create a new test file: Create a new file in your tests directory (e.g. tests/unit/my-test.js) to write your unit tests.
2. Import the necessary modules: In your test file, import the necessary modules such as Ember and ember-qunit:

1
2

import { module, test } from 'qunit';
import { setupTest } from 'ember-qunit';

1. Set up your test module: Use the module and test functions to define test modules and individual tests:

1
2
3
4

module('Unit | MyModule', function(hooks) {
  setupTest(hooks);

  test('it exists', function(assert) {
    // Write your test code here
  });
});

1. Write your test cases: Write your test cases inside the test functions using the assert object to make assertions:

1

assert.ok(true, 'Test passed!');

1. Run your tests: To run your unit tests, use the following command in your project directory:

1

ember test --server

Your unit tests should now run and display the results in the command line. Make sure to write tests for all the relevant functions and components in your Ember.js application to ensure its stability and reliability.
