Hello friends! today we will be studying about smoke testing. It is one of the most confused term in software testing and that is why it is also the most commonly asked question during interview. In this tutorial, we will get to know about smoke testing, its features and advantages.
Smoke testing is a type of testing in we execute the most crucial tests to make sure that the application can be considered for further exhaustive testing or not. It is also known as build verification testing.
It is performed right after the testing team receives the build. A subset of test cases is run over the build covering the most important functionalities. The functionality covered by the smoke tests are crucial, failing of which results in rejection of build.
Example- Smoke tests for some application like GMail will include test cases that are very critical to the app e.g. user should be able to login to the application, inbox should be populated with received mails, user should be able to compose and send mail etc.
Smoke testing got its name from testing of electrical appliances. In the past, the first thing to do while testing an electrical device was to plug it to a power outlet and see if it emits smoke or not. If there is no smoke then it means that the electrical circuits are not faulty and device can be tested for its functionality.
Same is the case with "Software Smoke testing", we check that the bare minimum functionality is working or not, in order to make a choice as to whether thorough testing needs to be done or not.
