Assignment Week 4

Writing Testable Code for ABAP 

When open SQL statements are performed in the code under test

When a currently failing depended-on component is created in the constructor

When do you need to change the product code first before you can write isolated tests?

The test double implements the interface of the depended-on component.

Test double inherits from the depended-on component and redefines unwanted methods.

The test double implements the test double interface.

The test double inherits from the CL_ABAP_UNIT_ASSERT class and redefines unwanted methods.

The test double implements all interfaces defined in the same package as the code under test.

Which test double implementations were shown in the course?

The innocent output of the code under test passed to the next test

The direct output from the code under test which is passed back to the test code

The indirect output of the code under test passed to the depended-on components

The asymmetric output which is passed from the code under test to the depended-on component and the code under test simultaneously

What kind of output of a code under test can a test case verify?

It focuses on recording the direct output of the code under test.

It focuses on recording the indirect output of the code under test.

It reports information about the depended-on component to the ABAP runtime for performance optimization.

Replace the depended-on components with test doubles.

Replace the code under test with a test double.

Replace the test with the code under test.

How can you limit the possible error locations discovered by unit tests?

With "lazy instantiation", depended-on components are not created if they are not needed in a specific use case.

With "lazy instantiation", depended-on components are created in the CONSTRUCTOR.

With "lazy instantiation", depended-on components are never created.

With "lazy instantiation", depended-on components are automatically created by the ABAP runtime.

Which of the following statements describes the technique of "lazy instantiation" for depended-on components?
