What is Mockito and what are its top alternatives?

Mockito is a popular Java framework used for creating mock objects in automated unit tests. It provides a simple and clean API for writing test cases and verifying behavior through mock objects. Mockito allows developers to simulate interactions with dependencies without the need for complex setups or external frameworks. However, one limitation of Mockito is that it does not support mocking of final classes or methods.

  1. PowerMock: PowerMock extends Mockito and other testing frameworks to allow mocking of final classes and static methods. Key features include support for mocking final classes and methods, integration with Mockito, JUnit, and TestNG, and compatibility with popular build tools. Pros include flexibility in mocking final classes and methods, but cons include increased complexity and potential for misuse.
  2. JMockit: JMockit is a mocking framework that offers advanced features for creating mock objects and verifying behavior. Key features include support for mocking final classes and methods, integration with JUnit and TestNG, and built-in support for code coverage analysis. Pros include powerful mocking capabilities, but cons include a steeper learning curve compared to Mockito.
  3. Mockk: Mockk is a mocking framework for Kotlin that provides a concise and expressive syntax for creating mock objects and stubbing behavior. Key features include support for Kotlin DSL, integration with popular testing libraries, and compatibility with Android development. Pros include Kotlin language support, but cons include limited documentation and community support compared to Mockito.
  4. EasyMock: EasyMock is a Java mocking framework that focuses on simplicity and ease of use for creating mock objects. Key features include support for creating mock objects with minimal code, integration with JUnit and TestNG, and compatibility with popular IDEs. Pros include simplicity in creating mock objects, but cons include less flexibility compared to Mockito.
  5. Spock Framework: The Spock Framework is a testing and specification framework for Java and Groovy that offers built-in mocking capabilities. Key features include support for writing specification-based test cases, integration with JUnit and TestNG, and a concise syntax for creating mock objects. Pros include expressive test case syntax, but cons include a learning curve for developers new to the framework.
  6. WireMock: WireMock is a standalone stubbing and mocking web service for testing HTTP-based APIs. Key features include support for creating mock HTTP endpoints, request matching and response stubbing, and integration with popular testing frameworks. Pros include comprehensive support for testing web services, but cons include setup and configuration overhead compared to Mockito for unit testing.
  7. PowerMockito: PowerMockito combines PowerMock and Mockito to provide enhanced mocking capabilities for final classes and static methods in Java tests. Key features include support for mocking final classes and methods, integration with Mockito, JUnit, and TestNG, and compatibility with popular build tools. Pros include extended capabilities for mocking final classes and methods, but cons include potential for misuse and increased complexity.
  8. WireMock.Net: WireMock.Net is a port of the WireMock HTTP stubbing and mocking web service for .NET applications. Key features include support for mocking HTTP endpoints, request matching and response stubbing, and integration with popular testing frameworks in the .NET ecosystem. Pros include the ability to test HTTP-based APIs in .NET applications, but cons include setup and configuration overhead compared to Mockito for unit testing.
  9. MockitoKotlin: MockitoKotlin is an idiomatic Kotlin wrapper for Mockito that provides a more Kotlin-friendly API for creating mock objects in tests. Key features include extension functions for Mockito classes, null safety in Kotlin, and seamless integration with Kotlin test frameworks. Pros include Kotlin language support and improved syntax for Mockito in Kotlin projects, but cons include the need for additional dependencies in Kotlin projects.
  10. Mockito2: Mockito2 is the latest version of the Mockito framework, which includes new features and improvements over the original Mockito library. Key features include enhanced mocking capabilities, improved error messages, and better integration with Java 8 features. Pros include continued support and updates for the Mockito framework, but cons include potential compatibility issues with existing Mockito codebases.

      We use JUnit for our Java Unit and Integration tests in Version 5. Combined with @JMockit2 and @truth (from Google) we perform all kinds of tests on our minecraft, standalone and microservice architecture.

      We prefer JUnit over TestNG because of the bigger community, better support and the generally more agile development. JUnit integrates nicely with most software, while TestNG support is a little more limited.

        Looking for some advice: we are planning to create a hybrid app for both iOS and Android; this app will consume a REST API. We are looking for a tool for this development with the following attributes:

        • Shallow learning curve; easiness to adopt (all team is new into mobile development, with diverse backgrounds: Java, Python & AngularJS),

        • Easiness to test (we discarded Angular-based tools already: creating a unit test in Angular we considered time-consuming and low value. At this point of the project, we cannot afford UI testing with Selenium/Appium based tools).

        • So far, we are not considering any specific capability of the device. Still, in the mid/long term, we would require the usage of GPS (geolocalization) and accelerometer (not sure if it's possible to use it from a hybrid app). Suggest any other tool if you wish.

        I chose WebdriverIO and Appium to implement a E2E tests solution on a native mobile app. WebdriverIO goes well beyond just implementing the Selenium / Appium protocol and allows to run tests in parallel out of the box. Appium has the big advantage of supporting iOS and Android platforms, so the test codebase and tools are exactly the same, which greatly reduces the learning curve and implementation time.

                    I'm working as one of the engineering leads in RunaHR. As our platform is a Saas, we thought It'd be good to have an API (We chose Ruby and Rails for this) and a SPA (built with React and Redux ) connected. We started the SPA with Create React App since It's pretty easy to start.

                    We use Jest as the testing framework and react-testing-library to test React components. In Rails we make tests using RSpec.

                    Our main database is PostgreSQL, but we also use MongoDB to store some type of data. We started to use Redis  for cache and other time sensitive operations.

                    We have a couple of extra projects: One is an Employee app built with React Native and the other is an internal back office dashboard built with Next.js for the client and Python in the backend side.

                    Since we have different frontend apps we have found useful to have Bit to document visual components and utils in JavaScript.

                    In 2012 we made the very difficult decision to entirely re-engineer our existing monolithic LAMP application from the ground up in order to address some growing concerns about it's long term viability as a platform.

                    Full application re-write is almost always never the answer, because of the risks involved. However the situation warranted drastic action as it was clear that the existing product was going to face severe scaling issues. We felt it better address these sooner rather than later and also take the opportunity to improve the international architecture and also to refactor the database in. order that it better matched the changes in core functionality.

                    PostgreSQL was chosen for its reputation as being solid ACID compliant database backend, it was available as an offering AWS RDS service which reduced the management overhead of us having to configure it ourselves. In order to reduce read load on the primary database we implemented an Elasticsearch layer for fast and scalable search operations. Synchronisation of these indexes was to be achieved through the use of Sidekiq's Redis based background workers on Amazon ElastiCache. Again the AWS solution here looked to be an easy way to keep our involvement in managing this part of the platform at a minimum. Allowing us to focus on our core business.

                    Rails ls was chosen for its ability to quickly get core functionality up and running, its MVC architecture and also its focus on Test Driven Development using RSpec and Selenium with Travis CI providing continual integration. We also liked Ruby for its terse, clean and elegant syntax. Though YMMV on that one!

                    Unicorn was chosen for its continual deployment and reputation as a reliable application server, nginx for its reputation as a fast and stable reverse-proxy. We also took advantage of the Amazon CloudFront CDN here to further improve performance by caching static assets globally.

                    We tried to strike a balance between having control over management and configuration of our core application with the convenience of being able to leverage AWS hosted services for ancillary functions (Amazon SES , Amazon SQS Amazon Route 53 all hosted securely inside Amazon VPC of course!).

                    Whilst there is some compromise here with potential vendor lock in, the tasks being performed by these ancillary services are no particularly specialised which should mitigate this risk. Furthermore we have already containerised the stack in our development using Docker environment, and looking to how best to bring this into production - potentially using Amazon EC2 Container Service

                          For our digital QA organization to support a complex hybrid monolith/microservice architecture, our team took on the lofty goal of building out a commonized UI test automation framework. One of the primary requisites included a technical minimalist threshold such that an engineer or analyst with fundamental knowledge of JavaScript could automate their tests with greater ease. Just to list a few: - Nightwatchjs - Selenium - Cucumber - GitHub - Go.CD - Docker - ExpressJS - React - PostgreSQL

                          With this structure, we're able to combine the automation efforts of each team member into a centralized repository while also providing new relevant metrics to business owners.
