function inject(tokens: any[], fn: Function): () => any;
Description
Allows injecting dependencies in beforeEach()
and it()
.
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) => { ... });
