Java Unit Tests Notes

Mockito

Mock a static method in a class

PowerMockito.mockStatic(StaticFactory.class);

PowerMockito.when(StaticFactory.create("Client")).thenReturn(client);

Mock a final class

In case you need a test with a mocked final class use annotations:

import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;
import org.powermock.core.classloader.annotations.PrepareForTest;

@RunWith(PowerMockRunner.class)
@PrepareForTest(FinalClass.class)
