Types of Traceability Matrix

Forward Traceability:
- Purpose: Ensures that all requirements are mapped to corresponding test cases.
- Description: It traces the test cases from the requirements to ensure that every requirement has been tested.
- Example: Starting from the requirements and checking if the test cases cover them.
Backward Traceability:
- Purpose: Ensures that no unnecessary test cases are included and all test cases trace back to valid requirements.
- Description: It traces from the test cases back to the requirements to ensure that the test cases are aligned with the requirements.
- Example: Starting from test cases and checking which requirements they validate.
Bidirectional Traceability:
- Purpose: Combines both forward and backward traceability.
- Description: Ensures that each requirement is covered by a test case (forward) and that each test case maps back to a requirement (backward).
- Example: Ensuring each requirement has associated test cases, and each test case is connected to a requirement.

Summary:

Forward Traceability: From requirements to test cases.
Backward Traceability: From test cases to requirements.
Bidirectional Traceability: Both forward and backward tracking.

Compatibility testing is a non-functional software testing process that checks whether an application works correctly across different environments—such as various browsers, devices, operating systems, hardware, networks, and databases. Its main goal is to ensure a consistent and seamless user experience, regardless of where or how the software is accessed1 2 4.

Types of Compatibility Testing

Software Compatibility: Verifies the application works on different operating systems (Windows, Mac, Linux), databases, and device types (mobiles, tablets, desktops)1 2 5.
Hardware Compatibility: Ensures the software functions properly with different hardware configurations (RAM, processor, graphics card, etc.)1 5.
Browser Compatibility: Checks the application's behavior across various web browsers and their versions1 5.
Network Compatibility: Tests performance and functionality over different network types, speeds, and conditions5.
Forward Compatibility: Confirms the software works with newer versions of platforms or environments1 5.
Backward Compatibility: Ensures the software remains functional with older versions of platforms or environments1 5.

Compatibility testing helps catch environment-specific bugs early, improves user satisfaction, and reduces the risk of issues after product launch1 2 4.
