The following action is to compile the documents needed for their smoke test. Using the command line, a user of Perforce’s smoke testing tool would download many test files to the local disc. Often, smoke testing is known as build verification or confidence testing. It refers to a similarly fundamental form of testing where a build passes the test if it doesn’t “catch fire” on the first turn-on — hence the term smoke. With smoke testing, we simplify the detection and correction of major defects.

  • If the software fails the initial smoke test, the software is handed back to the development team, where it is fixed and then sent back to QA.
  • The benefit is that if there are any errors in the sanity test cases, then errors can be reported sooner rather than later.
  • You have a few initial builds that are ready to be released for testing.
  • Additionally, smoke testing is not just confined to automated and manual testing.
  • To do this, one must prepare the test cases and test scripts and modify their approach to the tests they have selected .
  • A test suite that covers the main functionality of a component or system to determine whether it works properly before planned testing begins.

By frequently smoke testing your software, you can keep it relatively free of bugs. You can promise your users that any potentially harmful errors have been caught before they impact their experience. It applies to different software testing types, including integration, system, and acceptance testing. Smoke tests are build verification tests generally used at the start of any testing cycle for new builds. Smoke tests check to ensure that the primary requirements will be met; if not, they stop the build from being deployed. They should be carried out as soon as any new build is deployed or if there is any change.

Advantages of Regression Testing

The difference between smoke testing and sanity testing is, developers carry out smoke testing in the initial phase of the software development life cycle. Testers perform sanity testing after the smoke testing to ensure the software works correctly after code changes, bug fixes, or new functionality is added. Evaluate whether the software is ready for the next level of testing.

Where smoke testing ensures the working of software core functionality, it does not conduct in-depth testing. Even after Smoke testing the entire application, essential integration and system testing flaws may surface. Because of this, minor bug issues might go unnoticed in the software.

Tips by Experts for Smoke Testing

According to Wikipedia, the term ‘smoke testing” likely originated in the plumbing industry. Plumbers usually would use smoke to test for leaks and cracks in pipe systems. Smoke testing is just one example of how testing is woven through all of 3Pillar Global’s product development processes. Examples of major functions include logging in, adding records, deleting records, and generating reports. A test suite that covers the main functionality of a component or system to determine whether it works properly before planned testing begins. Smoke Testing does not cover all the functionality in the application.

Other than that, it does a quick evaluation of new software releases to ensure whether it’s ready or not for the next level of testing. It helps developers save time and energy by not passing the broken software for the next level of testing. A smoke test can be performed manually or by using automated tools.

What Does Smoke Testing Mean?

This prevents a QA team from attempting to run a full test of software that can’t complete basic functions. The process of automation typically involves yet another software engineering project. The most popular tools for building new testing automation focus on browser automation.

A smoke test can also be run as part of the build process in concert with a more thorough test when the build is a release candidate. With years of experience at our disposal, our testers have learned how to employ smoke testing strategically. Our in-depth knowledge of various testing procedures helps us find hidden issues in different components of the software and deliver the best solution for your business.

#1 Use Smoke Tests during the early stages of a project or product

Sanity testing is done during the release phase to check the main functionalities of the application without going deeper. Whenever a new software build is readied for release, pre-recorded smoke tests are performed in concurrence with the construct rather than performing the tests manually. A smoke test suite should include a modest number of tests that run quickly, even if fully automated, to be effective and purpose-built. At its core, smoke testing is used to establish whether the released software build is reliable or not.

And it all depends on how much ‘new’ stuff you’re putting into your product, and at what rate. In Extreme Agile environments, and if you have Continuous Integration and DevOps, well, go for as many smoke tests as you like or need. Smoke testing is usually performed manually, but it may also be performed through automation.


Smoke Testing comes into the picture at the time of receiving build software from the development team. The purpose of smoke testing is to determine whether the build software is testable or not. It is done at the time of “building software.” This process is also known as “Day 0”. To write the appropriate test cases, identify all of the areas of your product that you think a smoke test should touch and write out their core functionality step-by-step. Smoke testing occurs when a new program version is created and integrated with an already-deployed build in a QA or staging environment.

When you smoke test your foundational code, you increase the reliability of your builds. You also integrate new builds more easily because they will be relatively clean of significant issues. Smoke testing is a limited kind of testing with a small number of test cases.

Software Development

Fixing the identified issues becomes the programmer’s top priority. Once you have your suite of smoke tests defined, you’re going to want to think about automation. Given that the point of smoke testing is to determine quickly the state of the release and its readiness for full QA, you don’t what is smoke test want your suite to take more than a few minutes to execute. If you’re running 50 tests, and it takes half a day to run these tests, then your testing cycle is going to be too slow. A common first step for companies who want to build a suite of smoke tests is to first start with manual QA.
