MockK Description
Mocking is a method to make testing code more readable and manageable. In the following articles, I will explain the features, quirks, and basics of the MockK library. It is an open-source library (github repositories) that aims to make mocking in Kotlin great. Injection matches properties first by name, then by superclass or class. For customization, check the lookupType parameter. Even if the private option is used, properties are still injected. The greatest number of arguments is considered to be the most important.

Karate
Karate is the only open source tool that combines API test automation, mocks and performance-testing into a single framework. Cucumber's BDD syntax is language-neutral, making it easy for non-programmers. You can run parallel tests for speed and have assertions and HTML reports built-in. For teams that are not familiar with Java, there is a standalone executable that can be run on any platform. You don't need to compile code. You can simply write tests in a simple and readable syntax - designed for HTTP, JSON GraphQL, XML, and GraphQL. You can also mix UI and API test automation in the same test script. It is worth noting that JSON is a first-class citizen' syntax. This means that you can express your payload and expected data without using double-quotes. You also don't have to include JSON field names within quotes. You don't need to 'escape" characters as you would in Java or other programming languages.

JUnit
JUnit 5 will be the next generation of JUnit. The goal is to provide a solid foundation for JVM-side testing. This includes Java 8 and higher, as well as allowing many styles of testing. We need your support as our users to keep the pace going. No matter how many donations we receive, we will continue to work on JUnit. Your support would allow us to focus more on JUnit and not just on weekends or in our spare moments. We want to meet regularly and have colocated work for a few days so that we can get more done in face-toface design and coding sessions. Your donations will make this a reality!

Catch2
Catch2 is a unit testing framework in C++. However, it also offers basic micro-benchmarking and BDD macros. Catch2's greatest advantage is its simplicity and natural use. Test names don't have to be valid identifiers. Assertions look like regular C++ boolean expressions. Sections provide a convenient way to share setup and tear down code in tests. The v3 version is currently being developed and you are on the devel branch. v3 introduces a lot of changes. The most significant is that Catch2 is no more a single-header library. Catch2 behaves like a normal library with multiple headers and a separately compiled implementation. It's quick and easy to get started. You only need to download two files and add them to your project. No external dependencies. As long as C++14 can be compiled and the C++ standard library is available. You can write test cases using self-registering functions (or methods, depending on your preference).

PowerMock
Writing unit tests can be difficult and sometimes, good design must be sacrificed in order to ensure testability. Sometimes testability is synonymous with good design. However, this is not always true. Final classes and methods can't be used, private methods may need to be protected, or unnecessarily transferred to a collaborator. Static methods should be avoided entirely due to the limitations of existing frameworks. PowerMock is a framework which extends other mock libraries like EasyMock with greater capabilities. PowerMock employs a custom classloader, bytecode manipulation, and allows mocking of static methods and constructors. Private methods can also be used, as well as removal of static initializers. A custom classloader is not required to be modified to the IDE or continuous Integration Servers. This simplifies adoption.
