Ember.Test Class packages/ember-testing/lib/test.js:14

Clicks an element and triggers any actions triggered by the element's click event.

Example:

1
2
3

click('.some-jQuery-selector').then(function() {
  // assert something
});

Returns the current path.

Example:

1
2
3
4
5

function validateURL() {
equal(currentPath(), 'some.path.index', "correct path was transitioned into.");
}

click('#some-link-id').then(validateURL);

Returns the currently active route name.

Example:

1
2
3
4
5

function validateRouteName() {
equal(currentRouteName(), 'some.path', "correct route was transitioned into.");
}

visit('/some/path').then(validateRouteName)

Returns the current URL.

Example:

1
2
3
4
5

function validateURL() {
equal(currentURL(), '/some/path', "correct URL was transitioned into.");
}

click('#some-link-id').then(validateURL);

Fills in an input element with some text.

Example:

1
2
3

fillIn('#email', 'you@example.com').then(function() {
  // assert something
});

Finds an element in the context of the app's container element. A simple alias for app.$(selector).

Example:

1

var $el = find('.my-selector');

Like find, but throws an error if the element selector returns no results.

Example:

1

var $el = findWithAssert('.doesnt-exist'); // throws error

This injects the test helpers into the helperContainer object. If an object is provided it will be used as the helperContainer. If helperContainer is not set it will default to window. If a function of the same name has already been defined it will be cached (so that it can be reset if the helper is removed with unregisterHelper or removeTestHelpers).

Any callbacks registered with onInjectHelpers will be called once the helpers have been injected.

Example: App.injectTestHelpers();

Simulates a key event, e.g. keypress, keydown, keyup with the desired keyCode

Example:

1
2
3

keyEvent('.some-jQuery-selector', 'keypress', 13).then(function() {
 // assert something
});

Used to register callbacks to be fired whenever App.injectTestHelpers is called.

The callback will receive the current application as an argument.

Example:

1
2
3
4
5
6
7
8
9

Ember.Test.onInjectHelpers(function() {
  Ember.$(document).ajaxSend(function() {
    Test.pendingAjaxRequests++;
  });

  Ember.$(document).ajaxComplete(function() {
    Test.pendingAjaxRequests--;
  });
});

Pauses the current test - this is useful for debugging while testing or for test-driving. It allows you to inspect the state of your application at any point.

Example (The test will pause before clicking the button):

1
2
3
4

visit('/')
return pauseTest();

click('.btn');

This returns a thenable tailored for testing. It catches failed onSuccess callbacks and invokes the Ember.Test.adapter.exception callback in the last chained then.

This method should be returned by async helpers such as wait.

registerAsyncHelper is used to register an async test helper that will be injected when App.injectTestHelpers is called.

The helper method will always be called with the current Application as the first parameter.

For example:

1
2
3

Ember.Test.registerAsyncHelper('boot', function(app) {
  Ember.run(app, app.advanceReadiness);
});

The advantage of an async helper is that it will not run until the last async helper has completed. All async helpers after it will wait for it complete before running.

For example:

1
2
3
4
5
6
7
8
9

Ember.Test.registerAsyncHelper('deletePost', function(app, postId) {
  click('.delete-' + postId);
});

// ... in your test
visit('/post/2');
deletePost(2);
visit('/post/3');
deletePost(3);

registerHelper is used to register a test helper that will be injected when App.injectTestHelpers is called.

The helper method will always be called with the current Application as the first parameter.

For example:

1
2
3

Ember.Test.registerHelper('boot', function(app) {
  Ember.run(app, app.advanceReadiness);
});

This helper can later be called without arguments because it will be called with app as the first parameter.

1
2
3

App = Ember.Application.create();
App.injectTestHelpers();
boot();

This allows ember-testing to play nicely with other asynchronous events, such as an application that is waiting for a CSS3 transition or an IndexDB transaction.

For example:

1
2
3

Ember.Test.registerWaiter(function() {
  return myPendingTransactions() == 0;
});

The context argument allows you to optionally specify the this with which your callback will be invoked.

For example:

1

Ember.Test.registerWaiter(MyDB, MyDB.hasPendingTransactions);

This removes all helpers that have been registered, and resets and functions that were overridden by the helpers.

Example:

1

App.removeTestHelpers();

Replacement for Ember.RSVP.resolve The only difference is this uses an instance of Ember.Test.Promise

This hook defers the readiness of the application, so that you can start the app when your tests are ready to run. It also sets the router's location to 'none', so that the window's location will not be modified (preventing both accidental leaking of state between tests and interference with your testing framework).

Example:

1

App.setupForTesting();

Triggers the given DOM event on the element identified by the provided selector.

Example:

1

triggerEvent('#some-elem-id', 'blur');

This is actually used internally by the keyEvent helper like so:

1

triggerEvent('#some-elem-id', 'keypress', { keyCode: 13 });

Remove a previously added helper method.

Example:

1

Ember.Test.unregisterHelper('wait');

unregisterWaiter is used to unregister a callback that was registered with registerWaiter.

Loads a route, sets up any controllers, and renders any templates associated with the route as though a real user had triggered the route change while using your app.

Example:

1
2
3

visit('posts/index').then(function() {
  // assert something
});

Causes the run loop to process any pending events. This is used to ensure that any async operations from other helpers (or your assertions) have been processed.

This is most often used as the return value for the helper functions (see 'click', 'fillIn','visit',etc).

Example:

1
2
3
4
5
6
7
8

Ember.Test.registerAsyncHelper('loginUser', function(app, username, password) {
  visit('secured/path/here')
  .fillIn('#username', username)
  .fillIn('#password', password)
  .click('.submit')

  return app.testHelpers.wait();
});
