A set of useful helper for ember-cli acceptance tests. Includes
expectComponent, expectElement, and clickComponent.
expectComponent(componentName, count, options)
Passes when the component exists in the container and is in the DOM.
count optional, defaults to null. null means 'at least one'.
If an integer count is provided, there must be exactly that many components in the DOM.
If options.contains is set, the expectation only passes if the
component is in the DOM and contains the string from options.contains.
expectComponent can also be used in component integration tests. See expect-component-hbs-integration-test.js for an example.
Note that ember-qunit version 0.4.7 or greater is required to make the component integration tests work properly.
clickComponent(componentName, selector)
Clicks the CSS selector inside the component(s) of type componentName
in the DOM.
expectElement(selector, count, options)
Expect that count instances of the selector are in the DOM.
count is optional and defaults to 1.
If options.contains is set, the expectation will only pass if there
are exactly count instances of the selector that include the string
value of options.contains.
If options.message is set, the message will be displayed in the test results instead of the default, Found 0 of '.selector' but expected 1.
expectNoElement(selector, options)
A convenience for expectElement when the count is 0.
options can include a contains and/or a message key.

- Run
ember generate ember-cli-acceptance-test-helpers - Commit any file changes made if your application is under source code management
The generator makes changes to files assuming the structure of them has not changed much from the default version created during the initial Ember application creation. If too many changes have been made you will need to manually make the changes below instead:
- Add ember-test-helpers to your package.json:
npm install --save-dev ember-cli-acceptance-test-helpers- import the registerTestHelpers function in your
tests/helpers/start-app.js: - Add this line to to the top of
start-app.js:import registerAcceptanceTestHelpers from './201-created/register-acceptance-test-helpers';
- Register the test helpers:
- Add this line to
start-app.jsbeforeApp.injectTestHelpers registerAcceptanceTestHelpers();
- Add this line to
- Update your
tests/.jshintrcfile to notify it of the new globals that these helpers have added. Add the following lines to thepredefarray (after "currentRouteName"):
"expectComponent",
"clickComponent",
"expectElement",
"expectNoElement",
- You may need to restart your ember server so that it picks up the new .jshintrc file.
- Create an npm user if you don't have one using
npm adduser - ask a team member to add your user to npm for this project
- update the version in
package.json npm publish- Visit https://www.npmjs.com/package/ember-cli-acceptance-test-helpers and confirm the correct version number
If you have errors running npm adduser, you may have previously set your npm registry to a read-only or non-standard URL.
- Run this command to check
npm config get registry - Run this command to reset:
npm config set registry https://registry.npmjs.org/
- clickLink
- test/document
hasClassoption - a
within(selector/component, block&)helper - every expectation only adds 1 expectation, so it's easy to use
expect(X)
