Assertions & Test Organisation — quiz

You call assertEquals(expected, actual) and the test fails. Which statement about the failure message is true?

• JUnit 5 always shows 'expected: <X> but was: <Y>' automatically — no extra argument is needed
• JUnit 5 shows 'expected: <X> but was: <Y>' automatically, and you can prepend a custom message as the first argument to aid diagnosis
• You must always provide a failure message string as the first argument; otherwise JUnit 5 shows no details
• The message parameter is not supported in JUnit 5 — use assertThat with Hamcrest instead
