Smoke Testing Vs. Regression Testing: What’s Different?

What is Smoke testing?

It is a testing method that verifies whether a deployed software build is stable or not. It makes sure that the application’s crucial functionalities are working fine or not. A preliminary check of the software is done using this testing method, after a build and before a release. This testing method is performed whenever the software’s new functionalities are developed and integrated with an existing build that is deployed in the staging/QA environment.

What is Regression testing?

It is a testing method that ensures the new changes and updates that have been done to the code do not alter or modify the existing functionalities of the software application. Whenever there are new features being added or changes made in the code, regression testing is performed. These code changes could include updating a current feature, fixing bugs and adding new features. Already executed test cases are partially or fully selected and are re-executed to make sure that the existing functionalities are working just fine.

Difference between smoke testing and regression testing:

Smoke testing

  1. Developers and testers are responsible to perform this testing method
  2. Documentation is given due importance and is carried out effectively
  3. It is less expensive and can be managed under the budget allotted for software testing
  4. Only non-functional verification is carried out
  5. It is shallow/non-exhaustive by nature
  6. It is a surface level testing, wherein the stability of the system is verified
  7. This testing method is always followed by regression testing
  8. Less amount of time and manpower is required to perform this testing method
  9. It is performed on the software that has been newly developed
  1. The QA team is responsible to perform this testing method
  2. Documentation does not happen
  3. It is an expensive testing method and hence needs to be decided thoughtfully
  4. Both functional and non-functional verification is carried out
  5. It is in-depth by nature
  6. It is a deep level testing, wherein the rationality of the system is verified
  7. This testing method is performed throughout the software testing phase
  8. More amount of time is required to perform this testing method
  9. It is performed to make sure whether the changes made to the code do not alter or modify the existing features/functionalities of the application
