Solution

To understand what the JUnit assertion assertFalse(x1 <= x2) returns when x1 is greater than x2, let's break down the logic:

  1. Understanding assertFalse: The assertFalse(condition) method in JUnit asserts that the given condition is false. If the condition evaluates to true, the assertion fails, and the test will be marked as failed.

  2. Evaluating the Condition: The expression x1 <= x2 will evaluate to:

    • True if x1 is less than or equal to x2.
    • False if x1 is greater than x2.

  3. Case Analysis:

    • Given that x1 is greater than x2, the expression x1 <= x2 evaluates to False.
    • Consequently, when assertFalse(false) is called, it means that the assertion passes.

Final Answer

The assertion assertFalse(x1 <= x2) will return True when x1 is greater than x2, indicating that the assertion passed successfully.
