+## How does Bootstrap's test suite work?
+
+Bootstrap uses [QUnit](https://qunitjs.com/) and [Sinon](http://sinonjs.org/). 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, jQuery and Sinon).
+* `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
+
+To run the unit test suite via [Karma](https://karma-runner.github.io/), run `npm run js-test`.
+
+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](https://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 `npm run js-test` 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`](https://api.qunitjs.com/assert/expect/) to ensure that the expected assertions are run.
+* Each test should follow the project's [JavaScript Code Guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#js)
+
+## Code coverage
+
+Currently we're aiming for at least 80% test coverage for our code. To ensure your changes meet or exceed this limit, run `npm run js-compile && npm run js-test` and open the file in `js/coverage/lcov-report/index.html` to see the code coverage for each plugin. See more details when you select a plugin and ensure your change is fully covered by unit tests.
+
+### Example tests
+
+```js
+// Synchronous test
+QUnit.test('should describe the unit being tested', function (assert) {
+  assert.expect(1)
+  var templateHTML = '<div class="alert alert-danger fade show">' +
+        '<a class="close" href="#" data-dismiss="alert">×</a>' +
+        '<p><strong>Template necessary for the test.</p>' +
+        '</div>'
+  var $alert = $(templateHTML).appendTo('#qunit-fixture').bootstrapAlert()
+
+  $alert.find('.close').trigger('click')
+
+  // Make assertion
+  assert.strictEqual($alert.hasClass('show'), false, 'remove .show class on .close click')
+})
+
+// Asynchronous test
+QUnit.test('should describe the unit being tested', function (assert) {
+  assert.expect(2)
+  var done = assert.async()
+
+  var $tooltip = $('<div title="tooltip title"></div>').bootstrapTooltip()
+  var tooltipInstance = $tooltip.data('bs.tooltip')
+  var spyShow = sinon.spy(tooltipInstance, 'show')
+
+  $tooltip.appendTo('#qunit-fixture')
+    .on('shown.bs.tooltip', function () {
+      assert.ok(true, '"shown" event was fired after calling "show"')
+      assert.ok(spyShow.called, 'show called')
+      done()
+    })
+    .bootstrapTooltip('show')
+})
+```
