Final answer:
The correct answer is '4) All of the above', as the components of a test case include test input (data), test oracle (expected output), and comparator, which all work together to validate the system under test.
Step-by-step explanation:
The components of a test case typically includeTest input (data), which is the set of data that is fed into the system under test.Test oracle (expected output), which provides the expected result that the test is designed to produce.Comparator, a mechanism or step in the process that compares the actual output of the system with the expected output provided by the test oracleAll of these components together ensure that the system is tested thoroughly.
So, the correct answer to the student's question would be '4) All of the above' encompassing test input, test oracle, and comparator as integral parts of a test case.The components of a test case include:Test input (data): This is the input or data that is used for the test case.Test oracle (expected output): This is the expected output or result that the test case should produceComparator: This is the tool or method used to compare the actual output with the expected outputTherefore, the correct answer is 4) All of the above, as all of these components are necessary for a complete test case.
