Why are test cases needed?

Test cases are needed for:

• Structuring testing: They provide a systematic approach, covering all necessary scenarios.
• Documentation: They serve as a formal description of steps and expected results, making reproduction and defect tracking easier.
• Repeatability: They allow the same checks to be performed multiple times with predictable results.
• Communication: They help the entire team (developers, managers, other testers) understand what and how is being tested.
• Traceability: They link requirements with test scenarios, ensuring coverage.
• Progress tracking: They enable monitoring which checks have been completed, passed, or not.
• Training: They can be used for onboarding new team members.

Key elements of a test case:

• ID (Unique identifier)
• Title
• Description
• Preconditions
• Steps to execute
• Expected result
• Actual result (after execution)
• Status (Passed/Failed/Blocked)
• Priority
• Related requirements/features
