Ember-test-helpers NPM

ember-test-helpers

A test-framework-agnostic set of helpers for testing Ember.js applications.

Usage

This library is best used by way of a test-framework-specific wrapper, such as ember-qunit or ember-mocha.

Test Helpers

TestModule

The TestModule class is used to configure modules for unit testing different aspects of your Ember application. This class can be extended to create modules focused on particular types of unit tests.

TestModule is intended to be used in conjunction with modules specific to a test framework. For instance, you could create QUnit-compatible modules with a method such as:

function moduleFor(name, description, callbacks) {
  let module = new TestModule(name, description, callbacks);

  QUnit.module(module.name, {
    beforeEach() {
      return module.setup();
    },
    afterEach() {
      return module.teardown();
    }
  });
}

TestModule(name [, description [, callbacks]])

name - the full name of the test subject as it is registered in a container (e.g. 'controller:application', 'route:index', etc.).
description (optional) - the description of the test module as it should be displayed in test output. If omitted, defaults to name.
callbacks (optional) - an object that may include setup and teardown steps as well as the other units needed by tests.
callbacks.resolver (optional) - a Resolver instance to be used for the test module. Takes precedence over the globally set Resolver.

TestModuleForComponent

TestModuleForComponent extends TestModule to allow unit testing of Ember Components.

TestModuleForComponent(name [, description [, callbacks]])

name - the short name of the component that you'd use in a template (e.g. 'x-foo', 'color-picker', etc.).

TestModuleForModel

TestModuleForModel extends TestModule to allow unit testing of Ember Data Models.

TestModuleForModel(name [, description [, callbacks]])

name - the short name of the model that you'd use in store operations (e.g. 'user', 'assignmentGroup', etc.).

Miscellaneous Helpers

getContext / setContext - access the context to be used in each test.
setResolver - sets a Resolver globally which will be used to look up objects from each test's container.
isolatedContainer - creates a new isolated container for unit testing.
