To mock a static method powermock giving an exception while expect().
@Test
public void testRegistrarService()
{
mockStatic(IdGenerator.class);
expect(IdGenerator.generateNewId()).andReturn(42L);
long actualId=serTestObj.registerService();
replay(IdGenerator.class);
verify(IdGenerator.class);
assertEquals(42L,actualId);
}
public class ServiceRegistrator
{
public long registerService()
{
long id = IdGenerator.generateNewId();
return id;
}
}
public class IdGenerator
{
public static long generateNewId()
{
return System.currentTimeMillis();
}
}
Exception is:
java.lang.IllegalStateException: no last call on a mock available
