What is the significance of the async and fakeAsync utilities in Angular testing?
- async is used for asynchronous unit tests
- async is used for promise-based asynchronous tests
- fakeAsync is used for simulating asynchronous operations
- fakeAsync is used for synchronous unit tests
In Angular testing, the **async** utility is used to handle promise-based asynchronous tests, while the **fakeAsync** utility is used for simulating asynchronous operations in a synchronous manner.
