Smoke testing? Well, the phrase can be a little confusing but let’s make it easy for you. Consider that you are making a dessert. You must ensure the food is fully cooked before taking it out from the oven. Otherwise, you run the risk of becoming ill, ruining your design, and squandering time and money. So, simply put, software testing uses the same concept. The program must go through an initial validation procedure to ensure that it is reliable and free of any defects or vulnerabilities before being submitted for testing. Smoke testing, as tedious and time-consuming it may seem, is really quite worthwhile. However, you can automate your smoke tests with Selenium.

Smoke testing, the first stage of testing, is an excellent technique to determine if your basic operations are reliable. Naturally, no one loves the thought of doing more examinations. This little action may save a great deal of aggravation in the future and eventually result in better goods and more seamless product delivery.

12 Things You Should Know About Smoke Testing

Below-mentioned is a list of 12 things, that we have specially curated for you, that we think can be of great significance to you – when it comes to smoke testing, starting from basic to advance.

  1. The idea behind smoke testing is quite similar to how it sounds: just imagine, adding smoke to an airtight container and then inspecting for leaks. When smoke is seen exiting, you may be sure that something is amiss. Although it is not its intended use, it may not explain much about what is wrong or why. It just serves to notify you that there is a basic issue. Similar to smoke testing in software, it is a fast and sloppy approach to verify that your essential functionality continues to operate after making modifications to your codebase. It is frequently referred to as “surface level testing” or “build verification testing” since its primary goal is to simply show that an application continues to perform as anticipated, as opposed to thoroughly testing individual modules or functionalities.

Smoke testing is used when new modifications are performed to ensure that your core functionality continues to operate as intended. This kind of testing is akin to regression testing. Regression testing, on the other hand, often goes deeper and tests against certain modules. It is often inappropriate for a short “first pass” round of testing since it typically takes longer to run (by many orders of magnitude for suitably developed projects). Regression testing is significantly more in-depth than smoke testing and is meant to swiftly identify whether anything is incorrect at the surface level.

  1. To avoid wasting time and money on additional testing of broken software, the majority of QA teams employ smoke testing to identify significant software flaws as early as feasible. Before beginning more thorough testing, whether it be hardware testing, regression testing, or integration testing, they will first ensure that each software build can pass the smoke testing procedure. Additionally, when they lack the resources to run their whole regression suite as often as they would like, some teams employ smoke testing as a workaround. Smoke testing could be performed after submitting each new piece of code if they can only run the entire regression suite once a week to detect any significant flaws as soon as they are introduced. Teams may refer to smoke testing as “build acceptance testing” or “build verification testing” when it is utilized for this purpose.

Setting up a few tests to run on your live site periodically is another method to utilize smoke testing (such as every hour). This offers you the chance to identify problems as they arise and ensures that crucial processes are always operating as intended.

  1. Smoke testing is done to provide a quick indicator of whether or not anything has gone wrong. You know that an application has to be returned to the developers if it fails smoke testing.

Smoke testing does not, however, prove that there are no problems with an application; rather, it just shows that nothing significant stands out from the norm at first inspection. Because smoke testing may be completed significantly more quickly than other methods of testing, it is preferred. It’s a “early warning” approach designed to detect breaking changes and significant problems before longer test suites may deliver information on straightforward problems affecting the core functionality.

Simply said, smoke testing is crucial since it swiftly detects serious problems and show-stoppers. This enables developers to get feedback immediately and address any problems as soon as they arise.

  1. Smoke testing is superior to other testing methods. This can be proved in a variety of ways. Some of which have previously been noted, such as its speed compared to more formal tests. Smoke testing has a lot of other advantages, such as: They are very affordable and simple to operate. Smoke tests are fast and inexpensive to do, but they are not particularly thorough. Smoke tests are a particularly cost-effective method of revealing significant problems in code updates when the objective is to ensure that the overall functionality operates as planned. They don’t use a lot of time or resources to operate. They aid in early bug detection.

Typically, smoke tests are done as a preliminary check before more extensive testing is carried out. Bugs discovered during smoke testing are deal breakers that prohibit your application from functioning correctly. Smoke testing is ideal for detecting these kinds of serious problems as soon as they are discovered. In a nutshell, smoke testing increases QA effectiveness. This kind of testing may identify urgent issues without making you wait hours for whole test suites to execute. Your QA team won’t have to wait hours for a test suite to complete in order to find a significant problem by conducting smoke tests before other kinds of tests.

  1. Smoke testing aids in early bug discovery. Test frequently and early, as the adage goes. Finding flaws, aka bugs, in your program is made much easier by using smoke testing. You can prevent future rework and improve the likelihood of deploying better software if you find issues in software before it enters the testing process.
  1. Smoke testing is designed to be quick and affordable to do. You should think about reducing the number of tests you run if your smoke test suite is taking hours to complete. You need to strike a balance between running enough tests to adequately cover the essentials and not running so many that your test suite takes many hours to run. You should aim for somewhere between 20 and 50 tests as a very basic suggestion. If you have too many tests, your test suite will take too long to run against new code changes and you will likely miss some important ones if you have too few.
  1. This point is for you if you are debating between manual and automated smoke testing. Organizations often begin with manual smoke testing. This means making sure that navigational choices don’t adversely affect fundamental operations. If there are any vital glitches with the navigation pathways, the program should be returned to the creators for further revisions. Up till the program passes the test, the procedure is repeated. After you design a set of smoke tests, automation often enters the picture later on in the process. You may speed up the testing process before the product is sent to QA by automating smoke tests, which allows you to run several tests at once.
  1. The kind of tests that are likely to be included in a smoke test suite should also be taken into account when automating smoke testing. Your smoke tests will probably consist mostly of functional UI tests since smoke tests are a surface-level sort of testing meant to draw attention to significant functionality concerns. These tests are notoriously unstable since user interface elements are often moved around, frequently disrupting automated testing. It defeats the point of having a rapid and inexpensive set of tests in the first place if your developers spend time repairing faulty smoke tests prior to every release.
  1. Smoke testing is helpful for creating and executing a rapid set of tests to find any fundamental bugs or breaking changes that impact an application’s basic functioning in new code. Although they are designed to be fast and inexpensive to execute, smoke tests may be challenging to automate since they are often front-end functional UI tests.
  1. If any issues are discovered during smoke testing, the development team may begin debugging and doing root cause analyses much sooner rather than waiting for the results of the whole test suite. This is a result of smoke testing suites’ large coverage and short depth. Consider this test suite as a rough map of the application’s quality. If the build is only partially functional, it will be more efficient for developers to resolve any smoke-test errors while QA continues to do regression testing on that build. The developers may then focus on correcting any issues that QA discovered during the regression testing after addressing those bugs.
  1. Getting ready for the test plans is very advantageous since it will keep an eye on any potential tests that could continue to run on the system. It should be a document that is created at the same time the project is being developed. A test plan guarantees that every functional and design requirement will be carried out exactly as stated in the document.

A test plan acts as a manual for testing throughout the whole development cycle. If regression testing is performed later, the whole test plan may be reused. To ensure that no crucial component is left out, it should also contain regions of the program that are prone to errors. While creating the test cases, there should be consensus across all business stakeholders, project and product managers, developers, and QAs. It might be noted in the test plans as test requirements. The management will use this documentation primarily to understand the test scope and determine whether the appropriate areas are examined or not. In order for trainees to learn how to produce effective documentation, it is also helpful to them.

  1. In order to ensure that the quality criteria are met, the QA team often writes a document with the exact components for testing methods. Every organization, should seek for the greatest testing methods as well as the best procedures to use while conducting tests. In addition to this, organizations should create a thorough strategy and define objectives. These are the ideal practices to follow while doing smoke testing for your application in order to minimize manual labor.


The testing procedure is handled automatically using automation testing technologies. When we need to run a number of automated tests simultaneously and check the build right away once a bug is discovered, we conduct automated smoke tests.

Smoke testing may significantly cut down on testing time. Smoke testing may be completed in a matter of minutes if these tests are automated. Automating smoke tests can allow QA testers to provide quicker input on test builds if developers often produce builds or use continuous testing.

Lambda Test is quite a popular tool that may be used for automated smoke testing. With the help of the cross-browser testing platform Lambda Test, you can perform automation testing at scale across a virtual farm of more than 3,000 browsers and OS systems.
