xUnit jMockitのトリッキーな使い方

   @Test
   public void someTestMethod(@Mocked final DependencyAbc abc)
   {
      new NonStrictExpectations() {{
         abc.intReturningMethod(anyInt, null);
         result = new Delegate() {
            int aDelegateMethod(int i, String s)
            {
               return i == 1 ? i : s.length();
            }
         };
      }};

      new UnitUnderTest().doSomething();
   }

   @Test
   public void verifyExpectationWithArgumentValidatorForEachInvocation(
      @Mocked final Collaborator mock)
   {
      // Inside tested code:
      new Collaborator().doSomething(0.5, new int[2], "test");

      new Verifications() {{
         mock.doSomething(anyDouble, null, null);
         forEachInvocation = new Object() {
            void validate(double d, int[] i, String s)
            {
               assertTrue(d > 0.0);
               assertEquals(2, i.length);
               assertTrue(s.length() > 1);
            }
         };
      }};
   }
