What are the main criteria that test scenarios prepared at your previous workplace should meet?

Main criteria for test scenarios:

• Requirements coverage: scenarios should verify all functional and non-functional requirements.
• Repeatability: tests should produce the same result when run again under the same conditions.
• Clarity and unambiguity: scenario descriptions should be understandable and unambiguous.
• Isolation: each test should verify a specific aspect without dependencies on other tests.
• Reproducibility of errors: when a defect is found, the test should allow easy reproduction of the problem.
• Priority: critical functions are tested first.
• Automatability (if applicable): scenarios should be suitable for automation.

For example, a registration form test scenario should verify input correctness, error handling, and successful registration, be clearly described, and allow repeated testing without external influences.
