Smoke Testing vs. Sanity Testing in Functional Testing

Focus Keyword: Smoke Testing and Sanity Testing

When it comes to functional testing, it is essential to distinguish between smoke testing and sanity testing, two crucial testing techniques.

Smoke Testing:

Smoke testing is a preliminary testing approach that focuses on ensuring that the most critical functionalities of the software are working as expected. It is typically performed after a build to quickly identify any major issues that may prevent further testing. The goal of smoke testing is to determine if the software build is stable enough for more rigorous testing.

Sanity Testing:

Sanity testing, on the other hand, is a subset of regression testing that verifies specific functionalities after changes have been made in the code. It is more focused than smoke testing and aims to check if the particular features or functionalities impacted by the code changes are working as intended. Sanity testing helps ensure that recent code changes have not adversely affected the core functionalities of the software.

In summary, while smoke testing is a broad test to ensure the overall stability of the software build, sanity testing is a specific test to validate particular functionalities after changes are made. Both testing techniques play a crucial role in ensuring the quality and reliability of software products.
