What is Smoke testing?

Smoke testing is a software testing process that confirms whether an installed version of software is stable or not. This testing method is designed to test the basic functionality of the new version, and if the smoke test fails, it is very likely that the QA team will immediately reject the construction. As QA teams are involved in this process, the test is performed in a QA environment, to ensure that the product is stable and fully functional. It is also known as “build verification testing” or “confidence testing “.


Why Smoke testing matters?

Smoke testing is an integral part of the software development life cycle because it provides security in the correctness of the system in the initial phase.

It helps save a lot of time.

If the QA team approves the initial design, only then will further testing steps follow.

The smoke test puts the system in a better condition

It eliminates many errors in the initial phase.

Smoke testing reveals flaws in application functionality caused by new code changes or the addition of new functionality


What are the approaches of smoke testing?

Manual Smoke testing is performed to ensure that critical navigation is as expected and does not interfere with functionality.

Once development is released to QA teams, high-priority cases are checked to identify key deficiencies in the system. If the test passes, the teams move on to functional testing, and if the test fails, the build is rejected and returned to the development team for corrections.

QA teams are again performing smoke testing on the new version. It then integrates with older versions to maintain the correctness of the system.


Automated Smoke testing can be performed using a set of automated test cases. With the recording and playback function, the recorded smoke test cases can be reused whenever a new software version is applied.

Checks whether the main functionalities are working properly or not. If the test fails, corrections are done and bulid is redeployed immediately. Helps save team time and effort.


How to do smoke testing step by step?

Identify cases of smoke test:
This is a very important step in conducting a smoke test. It is necessary to identify a minimum number of test cases to cover key product functions so that they can be performed quickly. Select the necessary test cases that the developers have already identified.


Create a smoke test:
 An identified smoke test can be used to build test cases around them. Test cases are developed manually and test scripts can be created to perform automation.


Run a smoke test:
 Once smoke tests are created, they can be run to compile and analyze the results.


Analyze the smoke test:
Upon completion of the smoke test, the results can be analyzed to determine whether the build is a pass or a failure. If the test is successful, it is sent for functional testing, and if it is unsuccessful, it is returned to the development teams for re-build.



Smoke testing is the type of testing executed on every build without fail as it helps to find out defects in the early stages. This activity is the final step before a software build enters into a system stage. Mainly, applied to each build and only applied to new development as well as to the major and minor release of the system. It minimizes a test effort and improves the quality of an application. It’s conducted manually or by automation depending on the client and the organization.
