What is Smoke Testing? Definition and Examples

Instead of diving into the nitty gritty of the software code, it looks for fundamental problems that could cause severe failure. Passing the smoke test successfully is essential https://www.globalcloudteam.com/ to building a software application ready for release. That is why it has to be high up on your DevOps lifecycle’s continuous integration/continuous delivery (CI/CD) pipeline.

smoke testing definition

This tests whether a new software version is compatible with previous versions. This ensures new versions do not break the functionality of older versions and that data and files created with older versions can be used with the new version. Beyond the testing types that fall under function or non-functional testing, software testers can also implement several other software testing techniques. This is one smoke testing definition of the software testing types in software engineering conducted in-house by developers or testers to evaluate an application before it is released to the public. This involves integrating components one at a time and testing them as they are integrated. This helps to identify bugs early in the development process as you can tell if a component works correctly before integrating it with other components.

System Testing

This ensures software applications meet quality standards and work as expected. It helps collate information on user experience, functionality, and application performance. Feedback can then be used to identify issues or bugs to improve the user experience. This type of software testing evaluates whether the primary or critical features of a software application work as expected and whether the application is stable enough for further testing. This prevents time or resources being wasted on an unstable or faulty situation. Often this is done by software developers during the development phase, and it can be performed manually or with automated testing tools.

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. Smoke testing is carried out to test the system or product’s stability. Sanity testing is done to evaluate the system’s or product’s logic through testing.

How does Smoke Testing work?

In a CI flow, this is an automated process to keep pace with daily or even more frequent builds. Smoke testing in the practice of software development and software testing has become a commonly used technique for the early and continuous detection of software defects. There are many ways that smoke testing can be applied in software applications and systems. In this article, we explore some interesting history of how the term “smoke testing” originated, and then use that history as an analogy for finding defects in software and systems.

But, typically sanity testing does not have any specific test cases or test scripts. The identified smoke tests should be used to create test cases around them. The test cases are developed manually and test scripts can be created to perform automation. This sort of build verification testing is an effective process and is a verification method that can ensure that the product is stable and fully functional. Moreover, if a product fails this testing, then there is no point in further testing the product. If you run smoke tests on production, you can also catch bugs that earlier tests missed.

Automation Testing using TestComplete 11.0

When you don’t have a good smoke testing protocol, you’ll notice its absence in your bug rates. Remember, working on bugs when the critical portions of a program don’t work is a waste of time. Sarah saw the relevance of this as soon as she walked into BobCo. In the first month, while trying to get to know the team, she realized that they spent a lot of time working on bugs and solving them. Not just that, they were ignoring problems that some people would recognize as critical bugs.

Smoke test results have the unique requirement of rapid reporting. When a new build fails when smoke tests are performed, the failures must be reported and fixed immediately. In Figure 5, we see the status of smoke tests that are being performed as shown in PractiTest. We can see immediately in both of these definitions that smoke testing is typically not achieved in a single test case, but rather in a collection of tests. This collection of tests may vary in number, depending on the item being tested, but the goal remains the same – to find basic defects early before other work occurs on the item. Smoke tests can minimise test effort, and can improve the quality of the application.

thought on “Smoke Testing”

For example, configuration, code, regression, or environmental issues could exist. So the first build is subjected to smoke testing before sending it to other testing levels. Smoke testing targets key functionalities, and if key features aren’t working or major bugs haven’t been fixed, there’s no need to invest time in further testing. Smoke testing is a type of test that aims to confirm whether the basic functionalities of your software are working as intended. Smoke testing is done on one of the initial software builds when the software is at its most unstable phase. The results of smoke testing can give you a good idea of what’s working and what’s not in your app, allowing you a smooth transition into regression testing in the future.

A subset of test cases is run over the build covering the most important functionalities. The functionality covered by the smoke tests is crucial, failing which results in the rejection of the build. – Smoke testing is mostly used to check critical functionalities of a software build while sanity testing focuses on minor areas or minor functionalities. Smoke test has got its name from hardware repair systems wherein a smoke test is performed on pipelines to know whether they are working or not. Also there are rumours that smoke testing is a subset of regression testing.

Why we do smoke testing?

This could literally be one function in a code which computes a value based on some inputs. This function is part of several other functions of the hardware/software codebase that makes up the application. We may, however, utilize a collection of automated test cases to perform against Smoke Test. Whenever a new build is available for distribution, developers may use automated tests to validate it right away. The smoke tests certify the construction for more rigorous testing.

In this analogy, the pipes represent the functional process being tested. And, the faucets represent the controls often seen in systems to select or restrict certain functions. Any failure indicates a need to handle the system back to the development team.

Who will do Smoke Testing

Hopefully, by now, you have the basic knowledge of what smoke testing is. In conclusion, smoke tests offer a simple, straightforward yet supremely effective option to speed up finding bugs. Developers and others alike can use smoke tests in software projects, and can dramatically improve code quality.
