Summary
In this chapter, we covered three important topics related to testing in Angular: method stubs and spies, TestBed providers, and handling async operations and complex scenarios.
Firstly, we explored the concept of method stubs and spies, which allowed us to monitor and control the calls to dependencies in our tests. We learned how to create method stubs using Jasmine’s spyOn
function, which enabled us to replace a method’s implementation with our own custom behavior. This allowed us to test our code in isolation and ensure that it behaved as expected.
Next, we delved into TestBed providers, which are used to inject mocked dependencies into our tests. We learned how to use the TestBed.configureTestingModule
method to configure our test module and provide mocked instances of dependencies. This technique allowed us to control the behavior of dependencies and focus on testing specific scenarios without relying on real implementations.
Lastly, we tackled the...
