.l-main-section h2(class="function export") inject p <code>(tokens: List, fn: Function)</code> p.location-badge. exported from <a href="/angular2/test.html">angular2/test</a> :markdown Allows injecting dependencies in `beforeEach()` and `it()`. Example: ``` beforeEach(inject([Dependency, AClass], (dep, object) => { // some code that uses `dep` and `object` // ... })); it('...', inject([AClass, AsyncTestCompleter], (object, async) => { object.doSomething().then(() => { expect(...); async.done(); }); }) ``` Notes: - injecting an `AsyncTestCompleter` allow completing async tests - this is the equivalent of adding a `done` parameter in Jasmine, - inject is currently a function because of some Traceur limitation the syntax should eventually becomes `it('...', @Inject (object: AClass, async: AsyncTestCompleter) => { ... });`
