Study Notes
Regression Testing
Definition
- Regression testing is a type of software testing that involves re-executing a subset of test cases to ensure changes made to the software have not introduced new bugs or affected existing functionality.
Purpose
- Verifies that changes made to the software have not introduced new defects
- Ensures that existing functionality of the software remains unaffected
- Provides confidence that the software still meets required standards and specifications
Types of Regression Testing
- Unit Regression Testing: Focuses on individual units of code, such as functions or methods
- Integration Regression Testing: Focuses on the integration of multiple units of code
Approaches to Regression Testing
- Retest All: Re-executes all test cases to ensure changes have not affected the entire system
- Regression Test Selection: Selects a subset of test cases based on changes made to the software, reducing time and effort required for testing
Techniques for Regression Testing
- Test Case Prioritization: Prioritizes test cases based on risk, complexity, or business value
- Test Case Minimization: Minimizes the number of test cases required to achieve adequate coverage
- Test Case Selection: Selects a subset of test cases that cover changes made to the software
Tools for Regression Testing
- Test Automation Frameworks: Selenium, Appium, or TestNG
- Test Management Tools: JIRA, TFS, or TestRail
- Continuous Integration/Continuous Deployment (CI/CD) Tools: Jenkins, GitLab CI/CD, or CircleCI
