What basic principles of programming can be used when developing and executing tests?

When developing and executing tests, it is useful to apply basic programming principles such as:

• Modularity — dividing tests into independent parts so that each test checks a specific functionality.
• Code reuse — creating common functions and utilities to reduce duplication.
• Readability and clarity — writing tests in a way that they are easy to understand and maintain.
• Isolation — tests should be independent of each other so that the result of one does not affect another.
• Exception handling — proper management of errors and non-standard situations in tests.

These principles help create reliable, scalable, and maintainable test suites.
