What is the difference between integration testing and isolation testing?

What is the difference between integration testing and isolation testing?

Integration testing focuses on verifying the interactions between different modules or services, while isolation testing checks individual components in isolation.

Can you give me examples of when to use each type of testing?

Sure! Use integration testing when you want to ensure that different parts of your application work together, like when integrating a payment gateway. Use isolation testing when you want to test a specific function or module without external dependencies, like testing a utility function.

Which one is more important for software quality?

Both are important! Integration testing helps catch issues in interactions, while isolation testing ensures individual components are reliable. A balanced approach is best.

How do I implement these testing strategies in my project?

You can implement integration testing using frameworks like JUnit or TestNG for Java, and isolation testing can be done using mocking libraries like Mockito. Start by defining your test cases and gradually build your test suite.
