What are the main stages involved in the quality assurance process during software development?

The quality assurance process in software development typically includes the following main stages:

1. Test Planning — defining the objectives, scope, methods, and resources for testing.
2. Test Documentation Development — creating test cases, scenarios, and test data.
3. Test Environment Preparation — setting up the necessary hardware, software, and data.
4. Test Execution — running tests, collecting results, and identifying defects.
5. Analysis and Reporting — evaluating test results, documenting found errors.
6. Regression and Re-Testing — verifying fixed defects and the impact of changes on the system.

These stages help ensure product quality and minimize the number of errors in the final software.
