From submission to issuance, what intermediate stages can you mention?

The intermediate stages from submission to release can be represented as follows:

1. Requirements analysis — understanding what exactly needs to be tested.
2. Test environment preparation — setting up the environment, data.
3. Test case development — creating scenarios to verify functionality.
4. Test execution — manual or automated testing.
5. Defect registration — documenting found bugs.
6. Regression — retesting after fixes.
7. Reporting — preparing reports on quality and coverage.

This cycle helps ensure product quality from the start of development to release.
