/**
|
|
* Wraps a test function in an asynchronous test zone. The test will automatically
|
|
* complete when all asynchronous calls within this zone are done. Can be used
|
|
* to wrap an {@link inject} call.
|
|
*
|
|
* Example:
|
|
*
|
|
* ```
|
|
* it('...', async(inject([AClass], (object) => {
|
|
* object.doSomething.then(() => {
|
|
* expect(...);
|
|
* })
|
|
* });
|
|
* ```
