Junit Testing with Mockito Part 6 in Tamil | Springboot | Java | DinaTechy

In this course, we will take you through the fundamental concepts of JUnit testing and Mockito, and show you how to apply them effectively in a Spring Boot environment. JUnit is a powerful testing framework that enables developers to write automated unit tests, while Mockito is a widely-used mocking framework that simplifies the creation of test doubles. Mocking Exception Behavior: 1. We use doThrow(new RuntimeException("Database error")) to simulate an exception being thrown by employeeRepository.findById(employeeId). Testing the Catch Block: 2. The exception causes the catch block in checkEmployee to be executed, and the method returns "Failure". Assertions: 3. assertEquals("Failure", result); checks that the correct value is returned after the exception is caught. 4. verify(employeeRepository, times(1)).findById(employeeId); ensures that findById was called exactly once.
