Differences between Sanity and Smoke testing

SMOKE TESTING:

1. Smoke testing originated in the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch fire and smoke. In software industry, smoke testing is a shallow and wide approach whereby all areas of the application without getting into too deep, is tested.
2. A smoke test is scripted, either using a written set of tests or an automated test
3. A Smoke test is designed to touch every part of the application in a cursory way. It’s shallow and wide.
4. Smoke testing is conducted to ensure whether the most crucial functions of a program are working, but not bothering with finer details. (Such as build verification).
5. Smoke testing is normal health check up to a build of an application before taking it to testing in depth.

SANITY TESTING:

1. A sanity test is a narrow regression test that focuses on one or a few areas of functionality. Sanity testing is usually narrow and deep.
2. A sanity test is usually unscripted.
3. A Sanity test is used to determine a small section of the application is still working after a minor change.
4. Sanity testing is a cursory testing, it is performed whenever a cursory testing is sufficient to prove the application is functioning according to specifications. this level of testing is a subset of regression testing.
5. Sanity testing is to verify whether requirements are met or not, checking all features breadth-first.

Hope these points will help you to clearly understand the Smoke and sanity tests and will help to remove any confusion.

How can smoke testing be applied to mobile testing?

Smoke testing can be done on a Mobile once the latest build has been released to the testing team. Smoke test or build verification is nothing but just the basic functionality check for all the applications, test scope parameters that are involved in mobile application testing, testing very basic and important features of the mobile and also testing the showstopper issues at a higher priority level.
