Software testing is carried out at various levels to ensure the quality and functionality of a software product. The different levels of software testing include:

1. Unit Testing: Testing individual units or components of a software application in isolation.
2. Integration Testing: Testing the interaction between integrated components or modules.
3. System Testing: Testing the complete software system as a whole.
4. Acceptance Testing: Testing the software against the user's requirements.
5. Regression Testing: Testing to ensure that new code changes do not adversely affect existing functionality.
6. Performance Testing: Testing the performance and scalability of the software under different load conditions.

Each level of testing plays a crucial role in ensuring the overall quality and reliability of the software product.
