An example of an AI chatbot conversation about JUnit test assertions and their usage.
What are some examples of assertions in JUnit tests?
JUnit provides various assertion methods to validate test results. For example, you can use assertEquals(expected, actual) to check if two values are equal.
Can you give me more examples of assertions?
Sure! Here are a few more:
- assertTrue(condition) - checks if the condition is true.
- assertFalse(condition) - checks if the condition is false.
- assertNull(object) - checks if the object is null.
- assertNotNull(object) - checks if the object is not null.
How do I use assertArrayEquals?
You can use assertArrayEquals(expectedArray, actualArray) to compare two arrays for equality. It checks if both arrays have the same length and contain the same elements.
What happens if an assertion fails?
If an assertion fails, JUnit will throw an AssertionError, and the test will be marked as failed. You can see the failure message in the test report.
