Sanity testing is a narrow and focused testing to ensure core functionalities work, while smoke testing is a broader testing to check if the build is stable enough for further testing.

• Sanity testing is a subset of regression testing, focusing on specific areas of the application to ensure they still work after changes.

• Smoke testing is a preliminary testing to check if the build is stable enough for further testing, covering basic functionalities.

• Sanity testing is usually perf...read more

Regression testing is testing the entire application after a change, while retesting is testing a specific bug fix.

• Regression testing involves testing the entire application to ensure that new changes have not affected existing functionality.

• Retesting is testing a specific bug fix to ensure that the issue has been resolved.

• SDLC helps ensure that the software meets the requirements of the stakeholde...read more

STLC stands for Software Testing Life Cycle, which is a series of activities performed during the testing process.

• STLC consists of phases like requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has specific goals and deliverables to ensure the quality of the software.

• STLC helps in identifying defects early in the development cycle, reducing the cost of fixing them later.

• It ensures that the software meets the specified requirements an...read more
