BREAKING CHANGE:
`ComponentFixture` will be moving out of `@angular/compiler/testing` to `@angular/core/testing` in
this release. For now, it is deprecated from `@angular/compiler/testing`.
Previously, we were exporting internal mocks and helpers. Move these
to core/testing/testing_internal or remove them if they were
never used.
Remove deprecated items - injectAsync, clearPendingTimers.
BREAKING CHANGE:
Remove the following APIs from `@angular/core/testing`, which have been deprecated or were
never intended to be publicly exported:
```
injectAsync
clearPendingTimers
Log
MockAppliacationHref
MockNgZone
clearPendingTimers
getTypeOf
instantiateType
```
Instead of `injectAsync`, use `async(inject())`.
`clearPendingTimers` is no longer required.
BREAKING CHANGES:
`containsRegexp` is no more exported from `@angular/core/testing`. It should not have been part of the public API in the first place.
