What did the process of testing the new feature look like?

The process of testing a new feature typically includes the following stages:

1. Requirements and specifications analysis — understanding what exactly has been implemented and the acceptance criteria.

2. Test plans and test cases preparation — creating a set of scenarios covering functionality, including positive and negative cases.

3. Test environment setup — preparing the environment, data, necessary for testing.

4. Functional testing — verifying that the feature works according to the requirements.

5. Regression testing — ensuring that the new feature has not broken existing functionality.

6. Performance and security testing (if applicable).

7. Test automation — writing automated tests for reuse and speeding up verification.

8. Reporting and bug tracking — documenting found defects and interacting with developers.

9. Retesting and verification of fixes — checking the fixed bugs.

10. Release preparation — final testing and confirmation of readiness.

An important aspect is close interaction with the development team and constant communication to quickly identify and resolve issues.
