What is TDD in Java and how does it relate to integration testing?

TDD, or Test-Driven Development, is a software development process where tests are written before the code itself. In Java, this means you write a test case for a specific functionality, run it to see it fail, and then write the minimum code necessary to pass the test. Integration testing in TDD ensures that different modules work together as expected after individual unit tests.

Can you explain the steps involved in TDD?

Sure! The steps in TDD typically include: 1) Write a failing test for a new feature, 2) Write the minimum code to pass the test, 3) Refactor the code while keeping the tests green, and 4) Repeat the process for new features.

How do I implement integration tests in a TDD approach?

To implement integration tests in TDD, you would first write integration tests that cover the interactions between different components. After that, you can follow the same TDD cycle: write a failing integration test, implement the necessary code to pass it, and then refactor.

What tools can I use for TDD in Java?

Popular tools for TDD in Java include JUnit for unit testing, Mockito for mocking dependencies, and Spring Test for integration testing. These tools help streamline the TDD process.
