Which one is done earlier Smoke or Functional Test
#701143 - 03/12/12 10:27 AM

Hi as I know that Smoke Testing is done to check that Application's Core Functionality and as well as Critical Functionality are working right as per the specified requirements.I know when we don't have so much time to execute all Test Cases and Client is demanding application to deliver at his side. So we just check application functionality at core level whether it is working properly or not.
So please tell me according to this Scenario, Smoke Testing is done after doing Functional Testing. But Some of my friends told me that Smoke Testing is done first in most of the companies. Please guide me if smoke testing is done before the Functional Testing,then what is the reason behind doing smoke Testing First,why ?

Please share your experience.

Thanks & Regards,
Robin Tyagi

Keep in mind Functional Testing is a broad category, so I'll take it to assume you are talking about testing the new functionality.

Usually smoke tests are quick tests that can be performed right after a build is complete to give a quick thumbs up or thumbs down to wheter it gets delievered to QA at all. If something doesn't pass a smoke test, then you don't want to waste time testing it because it'll never be a release candidate nor do you want to waste any time regression testing it.

Smoke Test
A subset of all defined/planned test cases that cover the main functionality of a component or system, to ascertain that the most crucial functions of a program work, but not bothering with finer details. A daily build and smoke test is among industry best practices. [ISTQB]

Most places where I have worked, a Smoke Test is the first thing executed after handing over a new build to the test team.

If the Smoke Test indicates that the build is badly broken, then it is rejected. Otherwise, further testing then takes place.

Thanks dlai and joe for sharing your experience. Both of you give me a clear view regarding when we do Smoke Testing and why we do it firstly.

Thanks & Regards,
