Testing with JUnit 5 and Mockito

Testing with JUnit 5 and Mockito 

• Early bug detection: Test automation allows developers to catch bugs and issues early in the development cycle. By writing automated tests alongside their code, developers can quickly identify and fix problems before they propagate further into the software.
• Faster feedback loops: Automated tests can be executed rapidly, providing developers with immediate feedback on their code changes. This allows for quicker identification and resolution of issues, leading to faster iterations and more efficient development.
• Code refactoring and maintenance: Test automation provides a safety net for developers when refactoring or modifying existing code. Automated tests help ensure that changes made to the codebase do not introduce regressions, providing confidence to developers as they make modifications and improvements.
• Increased code coverage: Automated tests encourage developers to write more comprehensive test cases, increasing the overall code coverage. This helps in identifying edge cases, corner cases, and potential errors, leading to more robust and reliable software.
• Regression testing: Test automation is particularly valuable for regression testing. Developers can quickly run automated regression tests to ensure that previously implemented functionalities still work correctly after new changes are made. This helps prevent the reintroduction of previously fixed bugs.
• Collaboration and communication: Automated tests serve as a clear and executable specification of the expected behavior of the code. This helps improve collaboration between developers and other team members, facilitating effective communication and reducing ambiguity about system requirements.
• Continuous integration and delivery: Test automation integrates seamlessly with continuous integration and delivery (CI/CD) pipelines. Developers can incorporate automated tests into the build process, ensuring that changes pass all tests before being merged or deployed. This promotes a more agile and streamlined development workflow.
• Confidence in code changes: Automated tests provide developers with confidence in their code changes. By having comprehensive test coverage and passing test results, developers can be assured that their modifications have not adversely affected existing functionality.
• Time savings: While there is an initial investment in writing automated tests, it ultimately saves time for developers. Automated tests can be executed repeatedly without manual intervention, freeing up developers to focus on other critical tasks.
