## How does the test suite work?
|
||
|
||
Bootstrap uses [QUnit](http://api.qunitjs.com/), a powerful, easy-to-use JavaScript unit test framework. Each plugin has a file dedicated to its tests in `unit/<plugin-name>.js`.
|
||
|
||
* `unit/` contains the unit test files for each Bootstrap plugin.
|
||
* `vendor/` contains third-party testing-related code (QUnit and jQuery).
|
||
* `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
|
||
|
||
To run the unit test suite via [PhantomJS](http://phantomjs.org/), run `grunt test-js`.
|
||
|
||
To run the unit test suite via a real web browser, open `index.html` in the browser.
|
||
|
||
|
||
## How do I add a new unit test?
|
||
|
||
1. Locate and open the file dedicated to the plugin which you need to add tests to (`unit/<plugin-name>.js`).
|
||
2. Review the [QUnit API Documentation](http://api.qunitjs.com/) and use the existing tests as references for how to structure your new tests.
|
||
3. Write the necessary unit test(s) for the new or revised functionality.
|
||
4. Run `grunt test-js` to see the results of your newly-added test(s).
|
||
|
||
**Note:** Your new unit tests should fail before your changes are applied to the plugin, and should pass after your changes are applied to the plugin.
|
||
|
||
## What should a unit test look like?
|
||
|
||
* Each test should have a unique name clearly stating what unit is being tested.
|
||
* Each test should test only one unit per test, although one test can include several assertions. Create multiple tests for multiple units of functionality.
|
||
* Each test should begin with [`assert.expect`](http://api.qunitjs.com/expect/) to ensure that the expected assertions are run.
|
||
* Each test should follow the project's [JavaScript Code Guidelines](https://github.com/FezVrasta/bootstrap-material-design/blob/master/CONTRIBUTING.md#js)
|
||
|
||
### Example tests
|
||
|
||
```javascript
|
||
// Synchronous test
|
||
QUnit.test('should describe the unit being tested', function (assert) {
|
||
assert.expect(1)
|
||
var templateHTML = '<div class="alert alert-danger fade in">'
|
||
+ '<a class="close" href="#" data-dismiss="alert">×</a>'
|
||
+ '<p><strong>Template necessary for the test.</p>'
|
||
+ '</div>'
|
||
var $alert = $(templateHTML).appendTo('#qunit-fixture').bootstrapAlert()
|
||
|
||
$alert.find('.close').click()
|
||
|
||
// Make assertion
|
||
assert.strictEqual($alert.hasClass('in'), false, 'remove .in class on .close click')
|
||
})
|
||
|
||
// Asynchronous test
|
||
QUnit.test('should describe the unit being tested', function (assert) {
|
||
assert.expect(1)
|
||
var done = assert.async()
|
||
|
||
$('<div title="tooltip title"></div>')
|
||
.appendTo('#qunit-fixture')
|
||
.on('shown.bs.tooltip', function () {
|
||
assert.ok(true, '"shown" event was fired after calling "show"')
|
||
done()
|
||
})
|
||
.bootstrapTooltip('show')
|
||
})
|
||
```
