What is Smoke Testing? Introduction to Smoke Testing

It is of little use to do integration testing or other adavanced testing if the application fails to do some of the elementary things required for these advanced testing. For instance we have a web based application and we do smoke test to ensure we can load all the web pages, lets users to login/logout etc. These are the basic things that should work with the application to make it testable.

  • However, we can also use a set of automated test cases to run against Smoke Test.
  • To measures the stability of the software product by performing testing.
  • It’s valuable to be able to verify the stability of your builds early on.
  • Once the build has been delivered to QA, prioritized functionality test cases must be selected and examined in order to identify major flaws in the system.
  • If improving competency is one of your goals, then you shouldn’t skip smoke testing.
  • Automation smoke testing allows you to test batches of initial builds.

And the Defect found in later stages can be show stoppers where it may affect the release of deliverables. When you’re running smoke tests multiple times per day, it becomes especially important that you can triage test results very quickly. To learn more about choosing which test cases to include in your regression suite, read this article on automation test coverage. You can also learn more about software regression testing here. Sanity testing and regression testing are two other types of testing that often get confused with smoke testing.

This is why it’s easy to get the impression that these types of testing are interchangeable, and if you perform one, you can skip the others. Others think of regression testing as being the most important one, while the other two can be skipped without consequences. If any of the key features or functions of the software aren’t working, then the build is immediately rejected or redone.

There is another term, known as sanity testing, that is often misunderstood for smoke testing. You can even check out the details of the testing methodologies tool with the Software testing course online. Detect potential failures — Your smoke testing should capture areas with functionality issues. If you see an automation failing to enter data into all fields of an online form, that’s a sign that the application is not ready for more detailed regression testing. Smoke testing allows you to avoid spending time testing software that’s not ready for prime time. Smoke testing, sanity testing, and regression testing happen nearly at the same time in the software development life cycle.

Key Differences Between Smoke Testing and Regression Testing

Smoke Testing is also known as Confidence Testing or Build Verification Testing. Smoke testing is sometimes called “sanity testing”, “build verification testing” or “BVT”. The purpose of smoke testing is to find defects in software at a very basic level of functionality early after some form of integration.

You might also want to gather all your files for testing beforehand and ensure your smoke testing software works perfectly well. Smoke testing lets you uncover issues and save your development team time and money. To optimize smoke testing, make sure you know all of its characteristics and process steps. For example, in testing APIs, failures are often seen due to very basic defects.

Time and resources savings

Smoke tests frequently run quickly, giving benefits of faster feedback, rather than running more extensive test suites, which would naturally take longer. While repairing a hardware component, if the equipment works with no smoke, the component is said to have passed the test.

Smoke testing will be used to identify all of the glaring oversights in the release. Any error signals that the system must be returned to the development team.

Smoke testing is often referred to as “build verification testing”, and this term is pretty self-explanatory. To perform smoke testing, select a set of high-level test cases covering the critical features of the software. Execute these tests to ensure the major functionalities are working correctly. Also called regression testing, the automated method of smoke testing compares already recorded tests against a new software to catch and eliminate bugs and errors quickly. And, a perfect automation session can do more than test the software’s functionalities.

Find more bugs, faster, without adding headcount

When a build fails smoke testing, it means that the product has significant problems with quality which, when left unchecked, can lead to bigger issues, including loss of profit. It might take a long time to perform smoke testing for big projects in the case of manual smoke testing. Some organizations use test automation tools to perform smoke testing. Conducting smoke tests early on helps you ensure the quality of your programs.

Smoke Testing is a software testing method that determines whether the employed build is stable or not. It acts as a confirmation of whether the quality assurance team can proceed with what is smoke test further testing. Smoke testing is a process where the software build is deployed to a quality assurance environment and is verified to ensure the stability of the application.

Why Do We Call it Smoke Testing?

The software build may be stable or unstable during the smoke testing procedure. The software build is relatively reliable throughout sanity testing. Sanity testing is often carried out manually, without any automation techniques, compared to smoke testing, which can be carried out manually or by using automation tools.

Moreover, you can use this tool to perform manual testing easier, as well. Smoke testing and sanity testing are two different approaches to software testing. Although they both have the same goals—to ensure that your software is high quality, minimizes integration risk, and saves time—the approaches differ in subtle ways.

Unlike other QA tests that are exhaustive and check the overall code, smoke tests are fast and targeted. They are used to test new builds and ensure that the core or critical functions of the written program are working properly. As an example of how sanity and smoke testing compare, in a project’s first release, a development team releases the build for testing. Smoke testing involves testing the build for the first time in order to accept or reject the build. To build a smoke test, the test team first determines which parts of the application make up the high-level functionality. The team then develops automated procedures for testing the major parts of the system.
