Final answer:
Unit testing, integration testing, and system testing should be included in object class testing.
Step-by-step explanation:
The tests that should be included in object class testing are:
- Unit testing: This is used to test individual methods or functions within a class to ensure they are working correctly.
- Integration testing: This is used to test how different objects or classes interact with each other.
- System testing: This is used to test the behavior of the entire system or application.
Acceptance testing is not typically included in object class testing as it focuses more on the overall functionality and usability of the system from the end user's perspective.
