As there we specified in previews posts, we already talked about Regression Testing and Smoke Testing. Since for a lot of people it kind of sounds pretty similar here are some key differences we wanted to highlight, hope it helps
Purpose:
- Smoke testing checks the current build for the application / web site is stable enough for further testing.
- Regression testing ensures that new changes do not negatively impact existing functionalities, that might be impacted but he newest updates.
Timing (when are Smoke testing and Regression Testing executed):
- Smoke testing normally occurs at the beginning of testing, often after a new build is released.
- Regression testing is performed after making changes to the software, during the testing process, or before releasing a new version.
Scope:
- Smoke testing focuses on the critical features to identify show-stopping issues.
- Regression testing covers a broader set of test cases to ensure existing features remain intact by the new additions / fixes / changes.
Regression Testing Vs Smoke Testing Examples
Suppose a software development team has just completed the development of a web application for an e-commerce website. They have a new build of the application ready for testing. Before proceeding with comprehensive testing, the team decides to perform a smoke test to ensure the build is stable.
Assume that Smoke testing passes, and changes are now ready to release an updated version of the e-commerce web application. Before doing so, as a team we perform a regression testing to ensure that the bug fixes and new changes haven't affected the existing functionalities.
