                      QUESTION

                      Mockito Long not Zero ArgumentMatcher

                      Asked 2022-Apr-09 at 22:45

                      I am trying to refactor very old Java legacy tests using Mockito (mockito-core)1.10.19 to Mockito 4.

                      I have in the legacy the following matcher

                       private static long nonZeroLong() {
                          return longThat(not(0L));
                        }
                      

                      that should provide arg matchers for the following mock

                      doAnswer(invocation -> {
                            Runnable originalTask = invocation.getArgumentAt(0, Runnable.class);
                            Runnable runnable = () -> {
                                   /*
                                      LOCK is need here to emulate waiting on ConcurrentHashMap.compute method.
                                      It is uses `synchronized` block internally, so any technique which can throw
                                      interrupted exception for waiting can't be used here
                                   */
                              synchronized (LOCK) {
                              }
                              originalTask.run();
                              scheduledFutureExecuted.set(true);
                              futureExecutedSignal.countDown();
                            };
                            invocation.getArguments()[0] = runnable;
                            ScheduledFuture res = (ScheduledFuture) invocation.callRealMethod();
                            scheduledFutureRef.set(res);
                            return res;
                          }).when(pool).schedule(any(Runnable.class), nonZeroLong(), any());
                      

                      I am not mockito-guro but on a very first place I am not sure at all that this original way was suitable at all for this invocation, however it is the original way was done.

                      Since in Mockito 4 this argument matcher does not exist anymore I refactored it as :

                      private static long nonZeroLong() {
                          return  longThat(argument -> argument != 0);
                        }
                      

                      However I am still not sure what I provide will be the same as the original matcher in the legacy version.

                      My question is - will my matcher provide same logic as the original one?

                      Behaviour is the same.
                      But in your case, you created the custom ArgumentMatcher.
                      Better to use mockito Additional Matchers not(eq(value))

                          private static long nonZeroLong() {
                              return not(eq(0L));
                          }
                      

                      At least they improve readability of errors output and they have flexible implementation for any type.
                      Mokito matcher output:

                      Argument(s) are different! Wanted:
                      bean.print(not(0L));                                // We see actual problem 
                      -> at TestObject.testZeroMathers(TestObject.java:28)
                      Actual invocations have different arguments:
                      bean.print(0L);
                      -> at TestObject.testZeroMathers(TestObject.java:26)
                      

                      Custom matcher output:

                      Argument(s) are different! Wanted:
                      bean.print(<custom argument matcher>);              // We do not see actual problem
                      -> at TestObject.testZeroLongThat(TestObject.java:35)
                      Actual invocations have different arguments:
                      bean.print(0L);
                      -> at TestObject.testZeroLongThat(TestObject.java:33)

                      Install matchers

                      You can download it from GitHub, Maven.
                      You can use matchers like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the matchers component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .

                      Support

                      New matchers are welcomed as pull requests, as long as they are properly unit tested. If you add new matcher classes, be sure to add @Factory annotations to the static factory methods, and remember to add the new class to the matchers.xml file. This will ensure that the factory methods will be accessible in the common com.nitorcreations.Matchers class.
