@ember/test-helpers

What is @ember/test-helpers?

@ember/test-helpers is a package that provides a set of utilities to facilitate testing in Ember.js applications. It offers a variety of helpers to interact with the DOM, handle asynchronous operations, and manage application state during tests.

What are @ember/test-helpers's main functionalities?

Rendering Helpers

Rendering helpers allow you to render components or templates in the test environment. This is useful for testing the output and behavior of your UI components.

import { render } from '@ember/test-helpers';
import { hbs } from 'ember-cli-htmlbars';

await render(hbs`<MyComponent />`);

DOM Interaction

DOM interaction helpers enable you to simulate user interactions such as clicking buttons or filling in input fields. This helps in testing how your application responds to user actions.

import { click, fillIn } from '@ember/test-helpers';

await click('.my-button');
await fillIn('.my-input', 'new value');

Asynchronous Helpers

Asynchronous helpers like `settled` ensure that all asynchronous operations have completed before proceeding with the test. This is crucial for testing asynchronous behavior in your application.

import { settled } from '@ember/test-helpers';

await settled();

Routing Helpers

Routing helpers allow you to navigate to different routes within your application during tests. This is useful for testing the behavior of your application in different states and routes.

import { visit } from '@ember/test-helpers';

await visit('/my-route');

Other packages similar to @ember/test-helpers

ember-qunit

ember-qunit provides QUnit-specific helpers for testing Ember.js applications. It integrates seamlessly with @ember/test-helpers and offers additional utilities for setting up and tearing down tests.

ember-mocha

ember-mocha offers Mocha-specific helpers for testing Ember.js applications. Similar to ember-qunit, it works well with @ember/test-helpers and provides a Mocha-based testing environment.

ember-cli-page-object

ember-cli-page-object is a library for creating page objects in Ember.js tests. It provides a higher-level API for interacting with your application's UI, making tests more readable and maintainable.

@ember/test-helpers

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

Usage

The exports of this library are intended to be utility functions that can be used to bring the standard Ember testing experience to any testing framework.

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

Full documentation can be found in API.md.
