Whether you should choose smoke testing or regression testing depends on your testing goals. Smoke testing proves the stability or fallibility of software before doing further testing, but regression checks provide insights into software performance after some functionalities have been changed or added. 


Both testing methods are quite useful in their own right, having been deployed at different SDLC stages. That means both have unique sets of requirements and features, and there are vast discrepancies between what they can do. Still, however, there are varied reasons you might want to execute one ahead of the other during the building of your application.

Pitting smoke testing vs. regression testing, testers at UTOR take a look at the respective strengths of the testing types, so you can rightly decide the order of things or the right one to implement at a particular stage of the software development.

Explaining Smoke Testing

How does one really confirm that a build in its preliminary stage is stable? At this point, a confirmation test is mandatory. Hence, we define it as a confirmation of the pre-release quality of software. Smoke tests should be quick and frequent during the development stages.

Testers or developers attempt to flog the pre-production software: they test to flush out problems and fix them. They want to resolve issues promptly before moving to the next steps. To do this, developers usually spend a few minutes.

This test’s main purpose is to reduce errors initially, so no futile efforts are made in advanced testing. No evidence of anomaly means a PASS and that additional tests can proceed.
