refactor(testing): remove wrapping of Jasmine functions (#9564)
Instead, the async function now determines whether it should return a promise
or instead call a done function parameter. Importing Jasmine functions
from `@angular/core/testing` is no longer necessary and is now deprecated.
Additionally, beforeEachProviders is also deprecated, as it is specific
to the testing framework. Instead, use the new addProviders method directly.
Before:
```js
import {beforeEachProviders, it, describe, inject} from 'angular2/testing/core';
describe('my code', () => {
beforeEachProviders(() => [MyService]);
it('does stuff', inject([MyService], (service) => {
// actual test
});
});
```
After:
```js
import {addProviders, inject} from 'angular2/testing/core';
describe('my code', () => {
beforeEach(() => {
addProviders([MyService]);
});
it('does stuff', inject([MyService], (service) => {
// actual test
});
});
```

/**

* Wraps a test function in an asynchronous test zone. The test will automatically
|
|
|

|
|
|
|
|
* to wrap an {@link inject} call.
