In case you have to mock String, perhaps you can add a function only visible for testing via
import com.google.common.annotations.VisibleForTesting;
And in this function, mock the String type's value.
For Example:
class MyService {
private String name = "myservice";
@VisibleForTesting
void forTest(String mockName) {
this.name = mockName;
}
}
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.mockito.runners.MockitoJUnitRunner;
public class MyServiceTest {
private MyService myService;
@Before
public void setUp() {
myService = new MyService();
myService.forTest("mockName");
}
}
