• Test case ID and description
• Preconditions
• Test steps
• Expected results
• Actual results
• Status (Pass/Fail)

Test Scenarios: These are high-level descriptions of what needs to be tested. While test cases are detailed, test scenarios provide the broader context. For example, "Test user registration functionality" is a scenario that might include multiple test cases.

Defect/Bug Lifecycle: Understanding how bugs are reported, tracked, and resolved is essential. The typical lifecycle includes:

1. New: Bug is discovered and reported
2. Assigned: Bug is assigned to a developer
3. Fixed: Developer resolves the issue
4. Retest: Tester verifies the fix
5. Closed: Bug is confirmed as resolved

Testing Levels: Manual testing occurs at different stages:

• Unit Testing: Testing individual components
• Integration Testing: Testing combined components
• System Testing: Testing the complete system
• Acceptance Testing: Testing from user perspective
