Let's examine each option for clarity:

• Unit testing is typically conducted by the developer. This is accurate because developers have in-depth knowledge of the module's functionality, making them ideal for performing unit tests, often using assert methods.

• Integration testing is a form of white-box testing. This statement is incorrect. Integration testing is actually a type of black-box testing, focusing on the interactions between modules rather than their internal workings. Unit testing, on the other hand, is considered white-box testing.

• The internal workings of a module must be understood during Unit testing. Correct, as unit testing involves creating both positive and negative test cases based on the module's known functionality.

• Integration testing follows Unit testing in the testing sequence. True, as integration testing begins only after each module has been individually tested (unit tested) to ensure they work correctly together.

• Different modules can undergo Unit testing at the same time. This is possible because unit testing is performed independently on each module, allowing for simultaneous testing across different modules.
