To effectively use Mockito for Java unit testing, you must first add Mockito dependencies, add mockito-core dependencies in the Maven project, and add testImplementation'org.mockito:mockito-core:5.7.0' to the Gradle project; then create mock objects through @Mock annotation (combined with @ExtendWith(MockitoExtension.class)) or mock() method; then use when(...).thenReturn(...) and other methods to stub the method behavior of the mock object, or you can also configure different

This article explores how to effectively simulate external libraries or global properties defined on window objects in Jasmine and Karma unit testing environments. For common simulation failure attempts, the article proposes and elaborates on best practices for creating temporary mock objects using the beforeEach and afterEach lifecycle hooks, ensures test isolation, and provides code examples and considerations to help developers build robust unit tests.

I wrote about this a few years ago, but not in much detail. This is a more refined version of the same idea. Introduction Unit testing is both a blessing and a curse for developers. They allow quick testing of features, readable usage examples, scenarios for components involved in rapid experimentation. But they can also become messy, requiring maintenance and updates every time the code changes, and if done lazily, you can't hide the error instead of revealing it. I think the reason unit testing is so difficult is that it is related to testing, not code writing, and that unit testing is written in the opposite way to most other code we write. In this post, I will provide you with a simple pattern for writing unit tests that will enhance all benefits while eliminating most of the cognitive loss with normal code
