Baseline

In software testing, a baseline refers to a formally agreed-upon version or state of a product, document, or set of requirements that serves as a reference point for future development and testing. It is used to monitor progress, identify deviations, and ensure consistency throughout the software lifecycle.

Baselines are crucial for managing changes, enabling traceability, and providing a foundation for comparison during various testing phases.

Types of Baselines in Software Testing

1. Requirements Baseline:
   • A finalized and approved set of requirements that serve as a foundation for designing and testing.
   • Ensures that all stakeholders have a shared understanding of project goals.
2. Code Baseline:
   • The initial version of the source code used as a reference during development and testing.
   • Helps track changes and verify the stability of new builds.
3. Test Baseline:
   • A snapshot of the test artifacts (e.g., test cases, test plans, or results) at a specific stage.
   • Ensures consistency in test execution and evaluation across releases.
4. Performance Baseline:
   • Defines the system’s performance metrics (e.g., response time, throughput) under normal conditions.
   • Used to compare and measure the impact of updates or optimizations.

How Baselines are Used in Testing

1. Regression Testing: compare the current build with the baseline to ensure new changes haven’t introduced defects in existing functionality.
2. Performance Testing: measure performance improvements or degradations by comparing results with the baseline.
3. Verification and Validation: use baselines to confirm that changes meet the agreed-upon requirements and standards.
4. Audit and Compliance: establish baselines to demonstrate compliance with regulations or contractual agreements.
