This tool lets us re-write TypeScript sources before entering the emit pipeline.
For example, we lower Decorators to the tree-shakable Annotation form.
These worked in Dart because they were effectively exported even without the export keyword.
Without exporting these symbols, they are not produced in .metadata.json files, which leaves
dangling references from the Decorators that use them.
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
The filename contains the module name as resolved by users, so the top-level module name is uneeded.
Module names on references are replaced by capturing the import syntax from the module.
This allows readers of the metadata to do the module resolution themselves.

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
Introduces `ref-` to give a name to an element or a directive (also works for `<template>` elements), and `let-` to introduce an input variable for a `<template>` element.
BREAKING CHANGE:
- `#...` now always means `ref-`.
- `<template #abc>` now defines a reference to the TemplateRef, instead of an input variable used inside of the template.
- `#...` inside of a *ngIf, … directives is deprecated.
Use `let …` instead.
- `var-...` is deprecated. Replace with `let-...` for `<template>` elements and `ref-` for non `<template>` elements.
Closes#7158Closes#8264
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
Pure pipes as well as arrays and maps are
implemented via proxy functions. This is
faster than the previous implementation
and also generates less code.
BREAKING CHANGE:
- pipes now take a variable number of arguments, and not an array that contains all arguments.
