            Skipping a method execution using Mockito
            Asked 2022-Mar-21 at 09:41

            I’m using Mockito for unit testing and I want to skip the execution of a method.

            I referred to this ticket Skip execution of a line using Mockito. Here, I assume doSomeTask() and createLink() methods are in different classes. But in my case, both the methods are in the same class (

            You must always use your spy class when calling method().



            Mockito can not mock Random in Java 17
            Asked 2022-Feb-08 at 16:20

            Trying to update my project from Java 11 to Java 17 and got an unexpected error from Mockito in a specific test.



            Answered 2022-Feb-08 at 16:20

            The issue here is mockito (via ByteBuddy) is trying to use an inaccessible type at runtime (via reflection). From Java 9 onwards, not all modules are accessible unless you explicitly export/open them.

            As this is a runtime issue, you can add --add-opens as a JVM arg/CLI option to make this type accessible.

            As per the Oracle guide here, --add-opens does the following.

            If you have to allow code on the classpath to do deep reflection to access nonpublic members, then use the --add-opens runtime option.

            If you want to export internal types available in compile time as well, you can use --add-exports.

            To solve your specific issue; use the following.

            --add-opens java.base/jdk.internal.util.random=ALL-UNNAMED.

            ALL-UNNAMED means, a specified package is available in the entire codebase.

            However, mocking types that don't belong to you is not a good practice. Maybe, you can simplify this if there's an alternative.



            Java generics from Kotlin when verifying using Mockito?

            Mockito vs Mocktail in Flutter
            Asked 2022-Jan-19 at 16:49

            I am new on Flutter. I have started to writing tests. I saw mockito and mocktail as the most used testing libraries. I couldn't find any question/articles that explains differences between them. If there is a experienced developers -who used both of them- can you explain differences/advantages/disadvantages of them? Which one should I prefer?

            Thanks in advance!



            Answered 2022-Jan-19 at 16:49

            1. Assuming that you are new with Flutter, it would be probably easier for you to utilize the mocktail package.

            The main "inconvenience" with the mockito package is that you need to generate the mocks running flutter pub run build_runner build, define meta-annotations like @GenerateMocks, and imports like xxx.mocks.dart, and an extra build_runner dev dependency at your pubspec.yaml.

            The mocktail package simplifies mocking: you just need to extend the Mock class. That's it. Without code-generating, annotations, "magic" xxx.mocks.dart imports.

            2. Also, you have to keep in mind that the mocktail package is very new and has a stable history of just 10 months. The mockito package is a proven by time and developers library that has almost 8 years of history of stable releases: the library is well-known and is widespread among the Flutter and Dart community.

            With the experience, you will better understand which library better fits your projects' needs.

            PS: you can take a look at the code snippets of both packages.

            Unit testing retry in Spring Webflux with mocked response
            Asked 2022-Jan-19 at 15:18

            During unit testing retry the response of the mock seems cached, or most probably I am doing something wrong.

            I am trying to request something, if error happened then retry twice with delay of 1 second.



            Answered 2022-Jan-19 at 15:18

            someInjectedService.doSomething(...) will indeed technically be called only once.

            You could use Mono.defer(() -> someInjectedService.doSomething(someParam)) instead, to ensure the method is effectively called again, which should make your test pass.



            How to write Junit test for methods with local variables
            Asked 2022-Jan-14 at 12:00

            I have written a method which asks user to press enter to continue and timeouts after some time. I am facing difficulty in writing Junit tests for this method use Mockito. Below is the method.



            Answered 2022-Jan-14 at 11:58

            I would say you need to slightly change your method, take the callable object out of method and pass it as a parameter, this should solve your problem with mocking.



            How to mock JWT token to use it with Mockito and Spring Boot
            Asked 2021-Dec-26 at 05:59

            I have a controller which gives the user a 403 response unless they are authenticated with a JWT token which is passed as a Bearer token via the authorization header. I'm looking for resources on how to test this with Mockito but I'm not very successful so far as most of them tell me to use the @WithMockUser annotation, which I understand is for Spring security yes, but does not include the mocking for a JWT token. I've tried to mock a few objects such as the UserDetailsClass and the JwtFilter and even hardcoding the bearer token but I think there should be more to it.
