Regression Testing Task

A Regression Testing Task is a testing task that validates system functionality remains intact after system changes through test re-execution.

• AKA: Regression Test, Non-Regression Testing, Verification Testing Task, Stability Testing Task.
• Context:
  • It can typically detect unintended side effects introduced by system modifications through test execution.
  • It can typically maintain quality baselines by comparing current behavior against expected outcomes.
  • It can typically utilize test frameworks for efficient re-testing of test suites.
  • It can often prioritize critical path testing based on risk assessment and change impact analysis.
  • It can often integrate with change management systems for automatic triggers upon system updates.
  • It can often employ test selection techniques to optimize execution time while maintaining coverage.
  • It can range from being a Unit Regression Test to being a System Regression Test, depending on its scope level.
  • It can range from being a Selective Regression Test to being a Complete Regression Test, depending on its coverage extent.
  • It can range from being a Manual Regression Test to being an Automated Regression Test, depending on its execution method.
  • It can range from being a Functional Regression Test to being a Non-Functional Regression Test, depending on its quality focus.
  • ...
• Examples:
  • Software Regression Testing Tasks, such as:
    • API Regression Testing Task for interface contract validation.
    • UI Regression Testing Task for user interface stability.
  • Hardware Regression Testing Tasks, such as:
    • Circuit Regression Testing Task for electrical behavior validation.
    • Firmware Regression Testing Task for embedded system stability.
  • Process Regression Testing Tasks, such as:
    • Manufacturing Process Regression Testing for production quality maintenance.
    • Business Process Regression Testing for workflow integrity verification.
  • Domain-Specific Regression Testing Tasks, such as:
    • Agentic System Regression Testing Task for AI agent behavior validation.
    • Database Regression Testing Task for data integrity verification.
  • ML Model Regression Testing Tasks, such as:
    • Model Performance Regression Testing for accuracy maintenance.
    • Model Fairness Regression Testing for bias stability verification.
  • ...
• Counter-Examples:
  • New Feature Testing Task, which validates new functionality rather than existing behavior.
  • Exploratory Testing Task, which discovers unknown issues rather than known functionality.
  • Acceptance Testing Task, which validates requirements rather than stability.
