Milliseid meetodeid ja lähenemisviise kasutad testide väljatöötamisel nende tõhususe tagamiseks?

To develop effective tests, I use the following methods and approaches:

• Requirement planning and analysis — I clearly understand what exactly needs to be checked.
• Coverage of main scenarios and boundary cases — to make the tests as useful as possible.
• Dividing tests into levels: unit tests for logic, integration tests for component interaction, end-to-end tests for verifying user scenarios.
• Using mocks and stubs — to isolate tested components.
• Automating tests — so they can be run regularly and provide quick feedback.
• Updating tests — when changes are made to the code.

Example: when writing a unit test for a discount calculation function, I create tests with different input data, including zero and negative values, to verify the correctness of the function.
