|
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) => { ... });`
