What are the basics of assertions in JUnit 5?
JUnit 5 provides a powerful assertion library that allows you to verify expected outcomes in your tests. The basic assertions include methods like assertEquals, assertTrue, and assertFalse.
Can you give me an example of using assertEquals?
Sure! Here's a simple example: assertEquals(expected, actual); This checks if the expected value matches the actual value.
What happens if the assertion fails?
If an assertion fails, JUnit will throw an AssertionError, and the test will be marked as failed, providing feedback on what went wrong.
Are there any other assertion methods I should know about?
Yes, besides assertEquals, you can use assertNotNull, assertThrows, and assertArrayEquals, among others, to cover various testing scenarios.
