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
Before, all test framework wrappers (internal for dart and js/ts,
angular2_test for dart and testing for js/ts) had similar logic to
keep track of current global test injector and test provider list.
This change wraps that logic into one class managed by the test
injector.
Closes#5819
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.
See #5322
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}'.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
