Instantiating the test component within an NgZone will let us track async tasks in event handlers and change detection.
We can also do auto change detection when triggering events through dispatchEvent and not have to do fixture.detectChange() manually in the test.
New API:
ComponentFixture.autoDetectChanges() - This puts the fixture in auto detect mode that automatically calls detectChanges when the microtask queue is empty (Similar to how change detection is triggered in an actual application).
ComponentFixture.isStable() - This returns a boolean whether the fixture is currently stable or has some async tasks that need to be completed.
ComponentFixture.whenStable() - This returns a promise that is resolved when the fixture is stable after all async tasks are complete.
Closes#8301
Remove FunctionWithParamTokens.
All test wrappers async, fakeAsync and inject now return just a Function instead of FunctionWithParamTokens. This makes them directly consumable by the test framework. Also the test framework code does not have to handle a union of Function and FunctionWithParamTokens everywhere.
The Function returned by the above methods are considered asynchronous by the test framework if they return a Promise, synchronous otherwise.
Closes#8257
When a component uses a list of directives, such as `ROUTER_DIRECTIVES`,
make `TestComponentBuilder#overrideDirective` work properly for members
of the list.
Closes#7397Closes#8217
Update the version of zone.js to @0.6.12 that contains the new FakeAsyncTestZoneSpec.
The new fakeAsync zone handles errors better and clearPendingTimers() is no longer required to be called after handling an error and is deprecated.
The fakeAsync test zone will now throw an error if an XHR is attemtped within the test since that cannot be controlled synchronously in the test(Need to be mocked out with a service implementation that doesn't involve XHRs).
This commit also allows fakeAsync to wrap inject to make it consistent with async test zone.
BREAKING CHANGE:
inject can no longer wrap fakeAsync while fakeAsync can wrap inject. So the order in existing tests with inject and fakeAsync has to be switched as follows:
Before:
```
inject([...], fakeAsync((...) => {...}))
```
After:
```
fakeAsync(inject([...], (...) => {...}))
```
Closes#8142
Instead of using injectAsync and returning a promise, use the `async` function
to wrap tests. This will run the test inside a zone which does not complete
the test until all asynchronous tasks have been completed.
`async` may be used with the `inject` function, or separately.
BREAKING CHANGE:
`injectAsync` is now deprecated. Instead, use the `async` function
to wrap any asynchronous tests.
Before:
```
it('should wait for returned promises', injectAsync([FancyService], (service) => {
return service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
}));
it('should wait for returned promises', injectAsync([], () => {
return somePromise.then(() => { expect(true).toEqual(true); });
}));
```
After:
```
it('should wait for returned promises', async(inject([FancyService], (service) => {
service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
})));
// Note that if there is no injection, we no longer need `inject` OR `injectAsync`.
it('should wait for returned promises', async(() => {
somePromise.then() => { expect(true).toEqual(true); });
}));
```
Closes#7735
BREAKING CHANGE:
- Renderer:
* renderComponent method is removed form `Renderer`, only present on `RootRenderer`
* Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
now take the DebugInfo directly.
- Query semantics:
* Queries don't work with dynamically loaded components.
* e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
* 1. dirty check component inputs
* 2. dirty check content children
* 3. update render nodes
Closes#6301Closes#6567
Adds tests for public Dart and TS frameworks to make sure that
components with templateUrl can be created by the TestComponentBuilder.

Before #5375, injectAsync would check the return value and fail
if it was not a promise, to help users remember that they need to
return a promise from an async test. #5375 removed that with the
introduction of the testing zone.
This un-deprecates `injectAsync` until we can resolve
https://github.com/angular/angular/issues/5515.
To be clear, this means that `inject` and `injectAsync` are now
identical except that `injectAsync` will fail if the test
does not return a promise, and `inject` will fail if the test
returns any value.
Closes#5721
The component fixture returned from the test component builder
now exports `nativeElement` and `componentInstance` members
directly. They are also still available on the `debugElement`.
See #5385
Change beforeEachBindings to beforeEachProviders but preserve the
@deprecated method beforeEachBindings, in order to keep a working
deprecation warning
Use a zone counting timeouts and microtasks to determine when a test
is finished, instead of requiring the test writer to use
injectAsync and return a promise.

All common directives, forms, and pipes have been moved out of angular2/core,
but we kept reexporting them to make transition easier.
This commit removes the reexports.

Currently, core depends on the browser, which means that other platforms (e.g., NativeScript or webworker) cannot use the bootstrapping logic core provides.
This PR extract makes bootstrapping logic in core completely platform-independent. The browser-specific code was moved to "angular2/platforms/browser".
BREAKING CHANGE
A few private helpers (e.g., platformCommon or applicationCommon) were removed or replaced with other helpers. Look at PLATFORM_COMMON_PROVIDERS, APPLICATION_COMMON_PROVIDERS, BROWSER_PROVIDERS, BROWSER_APP_PROVIDERS to see if they export the providers you need.

This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
The test injector now uses an XHR implementation based on DOM.getXHR,
which allows the current DOM adapter to dictate which XHR impl should
be used.
To prevent the changes to DOM adapter from introducing undesired new
dependencies into the benchmarks, separate the async facade into
a promise facade which is reexported by facade/async.
