To create regression test cases, start by analyzing recent changes in the application to identify affected areas, highlighting interconnected features and critical workflows. Focus on areas prone to issues, test edge cases, and include scenarios that validate both intended improvements and overall system stability. Tailor the test set to ensure it thoroughly reflects the application’s current state and business priorities.
How to choose regression test cases?
Choose regression test cases by focusing on critical features, areas impacted by recent changes, and functions with high user activity or a history of bugs. Include tests that cover key workflows and dependencies to ensure stability and minimize risk.
How to do regression testing manually?
Manual regression testing is best performed after a build is completed and before its release, but it often becomes iterative due to evolving requirements. Assigning dedicated testers can increase focus and accuracy.
- Identify and rank code changes based on their impact.
- Define clear entry and exit criteria for testing.
- Develop a test schedule to organize execution.
- Set measurable pass/fail standards.
- Execute tests methodically and document outcomes.
How to improve regression testing?
Successful regression testing requires a clear strategy that combines automation, proper planning, and smart prioritization. Here’s a summary of the best practices:
- Automate Regression Testing: Use automation for repetitive and stable test cases to raise productivity. This saves time and resources, allowing manual testing to focus on more complex areas.
- Avoid the Pesticide Paradox: Rework and update your regression test suite regularly. Sticking to the same old test cases will stop revealing new defects. As the application evolves, new test cases should be added, and outdated ones should be refined or discarded.
- Impact Analysis: Identify which areas of the application are most affected by code changes. Work closely with developers and analysts to pinpoint these areas so that only the relevant sections are tested.
- Risk-Based Testing: Prioritize tests based on the critical functionality of the application. Focus on the most frequently used features and those that are business-critical, especially when time and resources are limited.
- Retest Defects: Retesting fixed defects from previous cycles is essential, as old bugs often resurface after updates. Confirm that past issues do not reoccur in the new release.
- Plan Regression Testing: Treat regression testing as a key part of the release cycle, not an afterthought. Without a clear plan and prioritization, it’s easy to overlook its importance. Establish a well-defined process to handle regression testing effectively.
