Which of the following best describes integration testing?

To answer this question, the user needs to know the definition of integration testing. Integration testing is a type of testing that verifies the interactions between different components of a system after they have been integrated.

Now, let's go through each option and explain why it is right or wrong:

A. Testing performed to expose faults in the interfaces and in the interaction between integrated components. This option is correct. Integration testing is performed to identify defects in the interfaces and interactions between integrated components.

B. Testing to verify that a component is ready for integration. This option is incorrect. This is not the purpose of integration testing. This type of testing is done before integration testing to ensure that individual components are functioning appropriately.

C. Testing to verify that the test environment can be integrated with the product. This option is incorrect. Integration testing is not concerned with testing the environment, but rather the interactions between different components.

D. Integration of automated software test suites with the product. This option is incorrect. This is not the purpose of integration testing. Automated testing is a separate process from integration testing.
