Smoke testing is a type of software testing that is used to quickly verify that the most important functions of a software application or system are working correctly. It is a shallow and narrow testing effort that is focused on determining if the system is stable enough to proceed with further testing.
Smoke testing is typically performed after a build or release of a software application or system, and is intended to provide a quick check that the system is functioning correctly and is ready for further testing. The goal of smoke testing is to quickly identify any major defects that would prevent the system from being tested further.
Smoke testing is often performed by developers or testers who are responsible for building and releasing the software, as they are in the best position to understand the changes that have been made to the system. It is typically a quick and informal testing process that is focused on verifying the stability of the system.
