JUnit 5 introduces functional interfaces like Executable, ThrowingConsumer, and ThrowingSupplier which streamline writing and understanding tests. These interfaces allow handling exceptions more efficiently in test scenarios, reduce repetitive code, and enhance the readability and maintenance of tests. By using these interfaces, you can test code paths that may throw exceptions, validate inputs, and ensure timely execution of operations.
