Have you ever talked about testing scenarios you created or used?

Yes, in my practice I have created and used various testing scenarios. For example:

• Functional testing: I checked the correctness of individual application functions by creating tests with different input data and expected results.

• Boundary testing: I created scenarios to test the system's behavior at minimal, maximal, and limit values.

• Regression testing: I used sets of tests to verify that new changes did not break existing functionality.

• Automated tests: I wrote scripts for automatic test execution, which sped up the testing process and increased reliability.

For example, for a web application, I created scenarios that tested user registration with different data combinations, including valid and invalid options.
