Sanity Testing Vs Smoke Testing Difference Between Them

However, there are always risks that the build might not work in your environment. 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. There are different types of software testing which includes unit testing, integration testing, system testing, sanity testing, smoke testing, interface testing and many more. Among these testing methods, smoke testing plays an important role as it is performed on each new build to check if the build is broken or can be moved to further testing.

Another theory states that the term ‘smoke testing’ originated from the hardware testing, where a device when first switched on is tested for the smoke from its components. In PractiTest, you can initiate the run of smoke tests, either in manual or automated ways. In Figure 4, you can see an example of smoke tests that are ready to run. A good starting point for building a more robust and complete set of tests is a set of simple smoke tests. Suppose, we have a large web application to test with thousands of test cases.

Software Testing MCQ

A new test category I’ve just become aware of is the canary test. A canary test is an automated, non-destructive test that is run on a regular basis in a live environment, such that if it ever fails, something really bad has happened. For details, You can even check out test automation strategies and methodology concepts with the Automation testing training. Also, in Figure 3 we also see regression and confirmation tests after release.

With black box testing you only know what the input is and what the output should be. Historically a developer or technical QA would write these tests using various tools such as Postman, SoapUI, JMeter and other tools like Testim. Taking the example of the first mobile banking app test, let’s see how a sample smoke test case look as implemented in PractiTest. A regression test might include both true and false sides of a business rule, user story or requirement.

Unit Test Vs Functional Test

If a piece of software passes a smoke test, quality assurance (QA) teams then proceed with further testing. A failure means the software must be handed back to the development team. Smoke Testing is a testing technique that is inspired from hardware testing, which checks for the smoke from the hardware components once the hardware’s power is switched on.

When a new project is released, the QA team decides the primary functionality of the application in order to do smoke testing. The QA team looks for show-stoppers in the app that is being tested. It is a basic test that indicates whether or not the product is ready to be tested.

Why Do We Do Smoke Testing?

By conducting smoke tests, you can promptly identify mission-critical failures and address them early in the development process, before diving into more intricate details. This proactive approach enables you to ensure the smooth functioning of your software and enhance its overall quality. This type of testing checks the stability of the code for each sprint with new code deployed. This testing method is executed before any detailed functional or regression testing is taken up as this testing process requires very less time to get an overview of the new code stability.

Regression tests target specific operations of software, taking a few hours to complete. This broad initial test is a more effective strategy to improve software code than if the team conducted specific and rigorous tests this early in the software development process. smoke test definition Sanity test is carried in a development environment on the software to check the accuracy of the application before submitting the build to QA. It is a procedure that ensures the application under construction satisfies its fundamental functional criteria.

Another example is how a plumber might inject smoke into a plumbing system to find leaks without the risk of water damage to walls. Smoke testing in software makes more sense when we see how the term originated. Another example of a smoke test could be the testing of if an item can be added to a cart in an e-shop. Again, a tester would launch a specified page and attempt to add the item to their cart. A successful test would see the item added to the cart, while a failure would result in an item not getting added to the cart.

  • The first thing you will check the car contains are for example if it’s four tires, a staring, headlight, or all other basic things.
  • Smoke Testing is also known as Confidence Testing or Build Verification Testing.
  • Sanity testing is the surface level testing where QA engineer verifies that all the menus, functions, commands available in the product and project are working fine.
  • Also, in Figure 3 we also see regression and confirmation tests after release.
  • In simple terms, we’re ensuring that the most important features are working and there aren’t any major problems in the code being tested.

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. The table below lists the main differences between smoke testing and sanity testing. Smoke testing is a software testing technique intended to ensure that essential features of a software application are functioning correctly. A smoke test is designed to identify any major issues that would prevent further testing of the software. Smoke Testing is a type of software testing which is usually performed on initial software builds to make sure that the critical functionalities of the program are working absolutely fine.

Then the test lead will instruct the testing team to do smoke testing and send the reports after performing the smoke testing. Once the testing team is done with smoke testing, they will send the smoke testing report to the test lead. As mentioned above, Smoke Testing focuses on the workflow of core applications so; we choose test case suits that covers the major functionality of the application. The number of test cases should be minimized as much as possible and time of execution must not be more than half an hour. In the smoke testing, we only focus on the positive flow of the application and enter only valid data, not the invalid data. In smoke testing, we verify every build is testable or not; hence it is also known as Build Verification Testing.

– The user should be able to log in to the application.– The inbox should be populated with received mail.– The user should be able to compose and send mail, etc. Any error signals that the system must be returned to the development team. We do Smoke Testing whenever there is a modification in the production to assure reliability. In layman’s words, we’re making sure that all of the critical features are operational so that there are no stumbling blocks in the current release.

PractiTest is recognized in Forrester’s Continuous Automation Testing Platforms report

The test cases are developed manually and test scripts can be created to perform automation. Delivers faster feedback which is a great advantage as this testing takes very less time and ensures whether the build can be progressed for further testing process. If we do not conduct smoke testing in the early phases, problems may be discovered later on when it is more costly.
