What is Smoke Testing?

It refers to software testing for determining the stability of the deployed build. The main objective of Smoke Testing is to verify that the QA team can process further testing. This testing is a minimal set of tests run on every build. It is a method where the software build is used for the QA environment and is tested for ensuring the stability of the application. Apart from it, It is also known as “Build Verification Testing” or “Confidence Testing.” In the smoke testing, testers can verify the essential feature is working, and there are no issues in the build. In other words, it also refers to a mini or rapid regression test of significant functionality.

What is Smoke Testing?

It is an easy test that shows the product is completely ready for the testing. It helps to determine if the build is flawed as to make any further testing a waste of time and resources. It must be performed on every build in Software Engineering without fail because it helps for finding errors in the early stages. Smoke test action is a final step before the software build registers the system stage. In software engineering, smoke tests should be performed on every build that is set to testing. Smoke tests apply to the new development and major or minor releases of a particular system. The QA team must ensure the correct build version of the application under test, and it should be done before performing smoke testing. It is an easy process that takes the least time for testing the stability of the application. It helps to minimize test effort and can increase the quality of the application. Most importantly, It can be done manually or by automation, but it depends on the client and the organization.

Process

In the smoke testing the build covers all data files, reusable modules, and libraries, engineered components that are needed for implementing one or more product functions.

Features

  • It helps to identify the business-critical functionalities, which satisfy the needs of a product.
  • Designing and executing the basic functionalities of the application.
  • It ensures that the smoke test passes each build to proceed with the testing.
  • Smoke Tests allow uncovering simple errors which save time and effort of the testing team.
  • The smoke Testing process can be manual as well as automated.

Aim

It aims:

  • For detecting any new defects in a software product.
  • For demonstrating system stability.
  • For demonstrating conformance to specifications.
  • For ensuring that the critical functionalities of the program are working fine.
  • For measuring the stability of the software product through performing testing.
  • For testing all over the function of the software product.

Who performs Smoke Testing?

It is performed after delivering the build to the QA environment, and it is by QA engineers. When there is a new build, the QA team determines the primary functionality in the application for performing smoke testing. QA team tests for showstoppers in a particular application that is under testing. Testing is done in the development environment on the code to ensure the correctness of the application before publishing build to QA, It is also known as Sanity testing.  Sanity testing defines the completion of the development stage and makes a choice to pass or not to pass software product for further testing stage.

Process

It is usually done by the manual platform, but there is a possibility of achieving the same through automation. It can differ from organization to organization. So let’s discuss this process in brief so that you can understand easily.

1. Manual Smoke testing:

As we know that smoke testing is done manually. This approach varies as per the needs and processes in an organization. The smoke testing is conducted for ensuring the navigation of necessary paths is as required and does not hamper the functionality. After the \ build is deployed to QA, then high priority functionality test cases are to be taken, and they are tested for finding the critical defects in a system. In case the test passes, then the tester continues the functional testing, or if the test fails, then the build is rejected and shipped back to the development team for the correction. For correction, QA starts smoke test with the new build version. It is performed on the new build, and then it will get integrated with the old builds for maintaining the correctness of that system. The QA team must check for the correct build versions before performing smoke testing. 

Smoke Testing by automation

It by automation is used for the regression testing but Tester can also use the set of automated test cases for running against Smoke Test. By the automation tests, developers or testers can check the build quickly, when a new build is ready for the deployment. It verifies whether the major functionalities still work correctly. If the test fails, then they can improve the build and redeploy the build quickly. By this, testers can save time and guarantee a quality build to a QA environment. By using an automated tool, the test engineer records all of the manual steps that are performed in the software build.

Smoke Testing cycle

The flowchart below explains the execution of Smoke Testing. After the build is deployed in QA, then smoke tests are proceeding for functional testing. In case the smoke test fails, then the tester can exit testing until the issue in the build is fixed.

Benefits

  • Simple to perform testing 
  • Imperfections will be distinguished in the early stages. 
  • Improves the nature of the framework 
  • Diminishes the hazard 
  • Progress is simpler to get to. 
  • Spares test exertion and time 
  • It runs rapidly 
  • Limits combination risks

Conclusion

Smoke Test is software testing for determining the stability of deployed build. The main objective of this testing is to verify that the QA team can process further testing. This testing is a minimal set of tests run on every build. In this article, we have discussed it completely regarding the overview, process,  and types so that you can understand every aspect of this testing.
