Mockito features and specs

Ease of Use
Mockito provides a clean and simple API that makes it easy to create mock objects and set expectations on them, which reduces the learning curve for new users.
Flexible Stubbing
Allows defining behavior for mock objects, including different outcomes for different inputs, which provides detailed control over the mocked behavior.
Enhanced Readability
The use of clear, human-readable language in test cases helps improve the clarity and maintainability of tests.
Integration with JUnit
Mockito integrates seamlessly with JUnit, a popular testing framework, leveraging annotations and runners for cleaner and more structured test code.
Active Community and Support
Backed by a large and active user community, ensuring constant updates, improvements, and plentiful resources for troubleshooting.

Possible disadvantages of Mockito

Limited Deep Mocking
Mockito can struggle with deep mocking scenarios where you need to mock chained or deeply nested calls, which can add complexity to test setup.
Static Method Limitations
Mockito does not natively support mocking of static methods, requiring additional tools or alternative approaches to handle such cases.
Potential Overuse
Extensive use of mocking might indicate poor design choices, such as tight coupling, and can lead to fragile tests that require significant maintenance.
Requires Understanding of Best Practices
Without understanding or adhering to best practices, developers might misuse Mockito, leading to over-mocking or inappropriate test setups.
Advanced Features Require Careful Use
Advanced features such as answers, spies, or argument captors can increase test complexity and require a deeper understanding to avoid introducing flaky tests.

How to improve third-party libraries with Kotlin extensions
The extensions are not particularly useful in this scenario because the described functionality can be incorporated into the Host class. On the other hand, they flourish in test frameworks like Kotest and enable the rapid development of useful add-ons like custom matchers. Extending third-party libraries with utility functions is another prevalent use case. In the next sections, we'll zero in on this specific aspect. - Source: dev.to / over 2 years ago

Effective Strategies for Writing Unit Tests with External Dependencies like Databases and APIs
For database interactions, tools like Mockito for Java or unittest.mock for Python allow you to create mock objects that return predefined responses or simulate specific behaviors like database query results or error conditions. This is especially useful for testing edge cases without needing to rely on a live database. - Source: dev.to / 7 months ago
Top 10 Java Testing Tools Every Developer Should Know
Mockito simplifies creating mock objects in unit tests, making it popular for behavior-driven development (BDD) in combination with frameworks like JUnit and TestNG. - Source: dev.to / 7 months ago
Tutorial: Build a Java SDK based on OpenAPI Spec
Testing is critical to maintaining the reliability of your SDK. For Java, tools Like JUnit and Mockito are Standard for unit testing and mocking. JUnit provides a simple, structured way to write tests, while Mockito allows you To mock objects in tests, which is particularly useful for API-driven SDKs where you need to simulate API responses. - Source: dev.to / 9 months ago
I build CRUDS as an intern. My boss told me my tests were ok, but too slow, so he modified them to run in a specific order to reuse the app context on all tests. Is that a good practice though?
I would say no. Mocking is generally creating a mock object. Like with Mockito. https://site.mockito.org. Source: about 2 years ago
