What are some examples of using EasyMock in Java?

EasyMock is a powerful mocking framework for Java. You can use it to create mock objects for unit testing. For example, you can mock a service class to test a controller without relying on the actual service.

Can you show me a code snippet for mocking a service?

Sure! Here's a simple example:

import static org.easymock.EasyMock.*;

public class MyServiceTest {
    public void testService() {
        MyService mockService = createMock(MyService.class);
        expect(mockService.doSomething()).andReturn("Mocked Result");
        replay(mockService);

        // Call the method under test
        String result = mockService.doSomething();
        assertEquals("Mocked Result", result);
        verify(mockService);
    }
}

What if I want to verify that a method was called a specific number of times?

You can use the times(int) method in EasyMock. For example:

expect(mockService.doSomething()).andReturn("Mocked Result").times(2);

This will verify that doSomething() was called exactly two times.

Are there any limitations to using EasyMock?

Yes, EasyMock works best with interfaces and abstract classes. It may not work well with final classes or methods, as they cannot be mocked.
