What can cause a test case for a decision table to fail after modifications? (Choose Two)

When considering what can cause a test case for a decision table to fail after modifications, the returned values used in the decision table is indeed a significant factor. If the values that the decision table is expected to return are altered—either intentionally or unintentionally—then any test case that relies on those expected outputs will fail. This is particularly critical because test cases are designed to validate the functionality against specific expected outcomes. Hence, any changes to those expectations (the returned values) can lead to discrepancies when the test cases are executed.

Furthermore, the output conditions of the decision table can also cause test cases to fail after modifications. These conditions dictate the precise circumstances under which certain values are returned, and any change to these conditions could alter the logic flow, resulting in different outputs than those anticipated when the tests were created. If the logic intended to handle specific inputs changes, then the associated test cases crafted under the previous logic framework may no longer yield the same results, leading to a failure in the tests.

Both of these aspects—returned values and output conditions—are essential in maintaining the integrity of test cases for a decision table. Changes to either can directly impact the overall correctness of the decision-making process encapsulated within the table and hence the success or failure of
