What are some advanced unit testing techniques in Angular?
Advanced unit testing techniques in Angular include using spies, mocking services, and testing asynchronous code with fakeAsync.
Can you explain how to use spies in my tests?
Sure! Spies allow you to track calls to a function and can be used to mock dependencies. You can create a spy using Jasmine's spyOn
method.
What about testing asynchronous code?
For asynchronous code, you can use the fakeAsync
and tick
functions from Angular's testing utilities to simulate the passage of time.
Are there any best practices for writing these tests?
Yes! Some best practices include keeping tests isolated, using descriptive names, and ensuring tests are fast and reliable.
