We have some internal proxies for all of the Jasmine functions, as well as some other helpers. This code hasn't been touched in more than 5 years, it can lead to confusion and it isn't really necessary since the same can be achieved using Jasmine.
These changes remove most of the code and clean up our existing unit tests.
PR Close#42177
Introduces an **internal**, **experimental** `profiler` function, which
the runtime invokes around user code, including before and after:
- Running the template function of a component
- Executing a lifecycle hook
- Evaluating an output handler
The `profiler` function invokes a callback set with the global
`ng.ɵsetProfiler`. This API is **private** and **experimental** and
could be removed or changed at any time.
This implementation is cheap and available in production. It's cheap
because the `profiler` function is simple, which allows the JiT compiler
to inline it in the callsites. It also doesn't add up much to the
production bundle.
To listen for profiler events:
```ts
ng.ɵsetProfiler((event, ...args) => {
// monitor user code execution
});
```
