What are the different testing techniques and how do they compare?

There are several testing techniques, including unit testing, integration testing, system testing, and acceptance testing. Each serves a different purpose in the software development lifecycle.

Can you explain unit testing and its advantages?

Unit testing focuses on individual components of the software to ensure they work as intended. Its advantages include early bug detection and easier code maintenance.

How does integration testing differ from unit testing?

Integration testing evaluates the interaction between different modules or services, while unit testing focuses on individual components. Integration testing helps identify issues in the way components work together.

What is system testing and when should it be performed?

System testing assesses the complete and integrated software to ensure it meets the specified requirements. It should be performed after integration testing and before acceptance testing.

Can you summarize the key differences between these techniques?

Sure! Unit testing checks individual components, integration testing checks interactions, system testing checks the entire system, and acceptance testing verifies the software meets user needs.
