Which of the following is usually performed after a build or version of the software is received, to ensure that the most crucial functions work as expected?

Correct option is D

Sanity Testing is a type of testing performed after receiving a software build to verify that the most crucial functionalities are working as expected before moving to more rigorous testing phases.
Important Key Points:
1. Sanity Testing is typically a quick, cursory check to ensure that the build is stable enough to proceed with further, more detailed testing.
2. It is usually conducted after minor changes or updates to verify the correctness of new features or bug fixes without conducting exhaustive tests.

· Unit Testing: Focuses on individual components or units of the software, ensuring each piece works correctly.
· Integration Testing: Tests combined modules to ensure they interact correctly.
· System Testing: Tests the entire system as a whole, including both functional and non-functional testing.
· Load Testing: Tests the system's performance under expected load conditions to determine its behavior under stress.
