i'm using junit in conjunction mockito. used mockito's verify method + junit assertion complete verification. not desirable? should use 1 or other not both?
there's nothing wrong using both.
mockito's verify used assert expect method(s) called expected value(s) on given mock(s).
junit's assertxyz used assert result desired result.
both valid verifications, , if both relevant, both should used.
for example, consider following (admittedly artificial) situation:
you have interface performs mathematical calculation:
public interface valueproducer { public int getvalue(int val); } and class doubles result produced it:
public class doubler { public static int doublethatresult (valueproducer producer, int val) { return 2 * producer.getvalue(val); } } testing require assert 2 things:
- that
getvaluecalled - that result doubled
so, e.g.:
public class doublertest { @test public void testdoublethatresult() throws exception { int value = 7; // or other value int returnmock = 13; // or other value valueproducer producermock = mock(valueproducer.class); when(producermock.getvalue(value)).thenreturn(returnmock); int actual = doubler.doublethatresult(producermock, value); verify(producermock); assertequals(26, actual); } }
