What is the importance of isolation testing in software development?

Isolation testing is crucial as it allows developers to test individual components independently, ensuring they function correctly before integration.

Can you explain how it differs from integration testing?

Sure! Isolation testing focuses on testing a single component in isolation, while integration testing checks how multiple components work together.

What are some common tools used for isolation testing?

Common tools include JUnit for Java, NUnit for .NET, and pytest for Python, which help automate the testing process.

How does isolation testing improve software quality?

It improves software quality by identifying bugs early, reducing the complexity of debugging, and ensuring each component meets its requirements.

Are there any drawbacks to isolation testing?

Yes, it can sometimes lead to a false sense of security if components are tested in isolation but fail when integrated due to unforeseen interactions.
