Smoke Testing vs Sanity Testing: What Are the Differences?

Smoke testing and sanity testing are two essential techniques in software testing that ensure the reliability and stability of applications. While both aim to identify major issues early, they differ in their objectives, execution, and focus areas. Smoke testing is performed after a new build release to verify critical functionalities and determine if it's stable for further testing. In contrast, sanity testing focuses on specific functionalities, ensuring their correctness after changes or additions. These tests can be executed using various automation tools like Selenium, Playwright, Cypress, Appium, and LambdaTest.
