Smoke testing Vs Sanity Testing | Difference | Comparison

In addition to determining whether the code is eligible for more tests, smoke and sanity testing are both quick to check the code's fundamental functionality. Smoke testing verifies that program-critical functionalities operate without error. While sanity testing verifies that the proposed functionality performs as expected. The majority of the time we mix up smoke testing and sanity testing. Let's learn the difference between the two methodologies in more depth about this misunderstanding. Let's debate Smoke testing vs sanity testing to better understand more about it.

What is Smoke testing?

Smoke testing is a kind of software testing used after a software build to ensure that the important features of the product function properly. It is run ahead of any comprehensive functional or regression test. Smoke testing is mostly used to reject software applications that have bugs so that the QA team won't waste time testing them.

What is Sanity testing?

Sanity testing is a type of software testing carried out following the delivery of a software build with minor code or feature modifications to ensure that the bugs have been fixed and no new problems have been brought about as a result of these changes. the objective is to establish that the proposed functionality performs essentially as anticipated.

Smoke testing Vs Sanity Testing | Difference between smoke testing and sanity testing:

  • Smoke testing seeks to validate stability, whereas sanity testing seeks to validate sanity.
  • The developer typically conducts sanity testing, whereas the quality assurance team typically performs smoke testing.
  • Sanity testing is not programmed or recorded, but smoke testing is.
  • On first builds, smoke testing is carried out, whereas sanity testing is done on builds that are generally reliable.
  • The system is currently undergoing smoke testing. A finished system is subjected to sanity testing.
  • Smoke testing was done by a developer or teaser of software. whereas sanity testing is carried out solely by the tester.
  • After a system enters production, smoke testing is conducted. Prior to a system entering production, sanity testing is conducted.
  • Basic testing includes smoke testing, whereas regression testing includes sanity testing.
  • Despite the fact that both tests are meant to be completed fast, sanity checks often take less time than smoke tests.
  • Smoke testing aims to find all flaws, even the smallest ones. Sanity testing looks for significant flaws.
  • Typically, smoke testing is carried out after each new build release. However, sanity testing is scheduled when there is not enough time for extensive testing.
  • While sanity testing resembles a specialist health checkup, smoke testing is comparable to a comprehensive physical.
  • Smoke testing is done to make sure the system will function in actual use. More sanity testing is done to demonstrate that the system will function.
  • Sanity testing is used to confirm new functionality, such as bug fixes, while smoke testing is used to confirm a system's essential features.
  • Only one element of the system is evaluated for sanity during the sanity testing process. During a smoke test, the entire system is validated.
  • During smoke testing, the software build could be either stable or unstable. At the time of sanity testing, the software build is largely stable.
  • Sanity testing verifies the system's precise functionality. Smoke testing examines the system's overall makeup.
  • Critical flaws are found via smoke testing, a more thorough method of testing. Basic functionality is often tested using sanity testing, a lighter, quicker type of testing.
  • Sanity testing is a focused and in-depth kind of testing. Smoke testing is a superficial and inclusive method of testing.
  • Smoke testing is performed to make sure the build is sound enough to be taken into consideration for conducting comprehensive testing. Sanity testing is carried out to make sure that a certain component or functionality of the program is functioning properly following a new repair.
