Parameters
tokens any[]
fn Function

Description

Example:

beforeEach(inject([Dependency, AClass], (dep, object) => {
  // some code that uses `dep` and `object`
  // ...
}));

it('...', inject([AClass], (object) => {
  object.doSomething();
  expect(...);
})

Notes:

  • inject is currently a function because of some Traceur limitation the syntax should eventually becomes it('...', @Inject (object: AClass, async: AsyncTestCompleter) => { ... });
