Usage

Add new assertions to test/assertions. Then use on the assert object in your test suite.

For example:

// tests/assertions/contains.js
export default function(context, element, text, message) {
  message = message || `${element} should contain "${text}"`;
  let actual = context.$(element).text();
  let expected = text;
  let result = !!actual.match(new RegExp(expected));
 
  this.pushResult({ result, actual, expected, message });
}
 
// tests/acceptance/foo-test.js
test('foo is bar', function(assert) {
  visit('/');
 
  andThen(function() {
    assert.contains('.foo', 'Foo Bar');
  });
});

Note: hyphenated file names like tests/assertions/double-trouble.js will be camelized: assert.doubleTrouble

Blueprint

You can generate a new assertion by using the assertion blueprint:

ember g assertion double-trouble

Assertion

A context is always injected as the first argument. You don't need to pass a context when calling the assertion.

// good
assert.contains('.foo', 'Foo bar');
 
// bad
assert.contains(app, '.foo', 'Foo bar');

Setup

You must inject the assertions to use them in tests.

New testing API

import { module, test } from 'qunit';
import { setupTest } from 'ember-qunit';
import setupCustomAssertions from 'ember-cli-custom-assertions/test-support';
 
module('default setup', function(hooks) {
  setupTest(hooks);
  setupCustomAssertions(hooks);
 
  test('can inject custom assertions', function(assert) {
    assert.contains('.foo', 'Foo bar');
  });
});

Old testing API

// ...
import { assertionInjector, assertionCleanup } from 'ember-cli-custom-assertions/test-support';
 
module('Acceptance | foo', {
  beforeEach: function() {
    var application = startApp();
    assertionInjector(application);
  },
 
  afterEach: function() {
    Ember.run(application, 'destroy');
    assertionCleanup(application);
  }
});
