Best Test Automation Frameworks for Java

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!

Selenium automates browsers. That's all there is to it! It's up to you what you do with this power. It is primarily used to automate web applications for testing purposes. However, it is not limited to that. Boring web-based administration tasks are also possible (and should) be automated. Selenium WebDriver is a collection language-specific bindings that allows you to drive a browser the way it was intended to be driven. It will allow you to create robust browser-based regression automation suites, tests, scale, and distribute scripts across multiple environments. Selenium WebDriver is a Chrome and Firefox addon that allows you to quickly create bug reproduction scripts or scripts to assist in automated exploratory testing. It will record and playback all interactions with the browser. You can scale by running tests on multiple machines and managing multiple environments from one central point.

You don't have to know how to shut down browser, handle StaleElement exceptions and timeouts, or search for relevant log lines when debugging your tests. Selenide is so easy that you don’t need to read a lot of documentation. Selenium WebDriver can be a great tool but it is not a tool for testing. It is a tool for browser manipulation. Selenium WebDriver has many testing libraries. However, they don't seem to address the main issues of UI testing. Instabilities of tests due to dynamic content, JavaScript and Ajax, as well as timeouts, etc. Selenide was designed to solve these problems. Selenide is a stable test solution that resolves (almost all) Ajax/timing problems.

Validating REST services in Java can be more difficult than in dynamic languages like Ruby and Groovy. REST Assured brings the simplicity and ease of these languages to the Java domain.

Playwright supports all modern rendering engines, including Chromium and WebKit. You can test on Windows, Linux, or macOS. Playwright waits for the elements to become actionable before he can take any actions. It also offers a wealth of introspection events. Combining the two reduces artificial timeouts, which is the main cause of flaky tests. Playwright assertions were created for the dynamic web. Checks are automatically retried until all conditions are met. To eliminate flaky bits, configure test retry strategy, capture execution trace and screenshots. Browsers can run web content from different origins in different ways. Playwright is compatible with modern browser architectures and runs tests out of-process. Playwright is free from the limitations of in-process test runners.

Mockito is a mocking tool that tastes great. It allows you to write beautiful tests using a simple API. Mockito won't leave you feeling hungover. The tests are easy to read and produce clear verification errors. Learn more about the features and motivations. The top 10 Java libraries across all libraries, and not just the testing tools. An analysis of 30.000 GitHub projects was done in late 2013. Mockito was ranked 9th in the main report. However, mockitocore and mockito all are the same tool so Mockito's actual position is number 4, just above Spring and Guava. This study is an indicator of the huge impact Mockito has on Java unit tests.

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.

Robot Framework is an open-source automation framework. It can be used to automate test automation as well as robotic process automation (RPA). Robot Framework Foundation supports Robot Framework. Robot Framework Foundation supports many industry-leading companies in their software development. Robot Framework is extensible and open-source. Robot Framework can be used in conjunction with almost any other tool to create flexible and powerful automation solutions. Robot Framework is available for free without any licensing fees. Robot Framework uses human-readable keywords and a simple syntax. Libraries that are written in Python, Java, or other programming languages can extend its capabilities. Robot Framework is part of a rich ecosystem that includes libraries and tools, each developed in its own projects.

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.

Serenity BDD makes it easier to write automated acceptance and regression test scripts that are more manageable and easy to maintain. Serenity BDD also uses test results to create illustrated, narrative reports that describe and document your application's functionality and operation. Serenity will tell you not only which tests were executed but also what requirements were tested. Serenity BDD has the advantage that you don't have to spend time building and maintaining your automation framework. Serenity's goal is to make it simple to quickly create well-structured and maintainable automated acceptance criteria using your favorite BDD or traditional testing library. You can work with Behaviour-Driven-Development tools like Cucumber or JBehave, or simply use JUnit. You can integrate with requirements stored outside (such as JIRA, or any other test case management tool), or use a simple directory-based approach for organizing your requirements.

Framework for automated integration testing that supports a wide variety of data formats and message protocols! A typical scenario is where the system under test runs on a test infrastructure and interacts with Citrus via various messaging transports. Citrus can act as both client and consumer during the test, exchanging real request/response message messages over the wire. Each test step allows you to validate the messages exchanged with expected control data, including attachments, message headers and body content (e.g. XML, Json, ...). The test provides a Java fluent API for specifying the test logic and can be fully automated. The repeatable test is nothing more than a JUnit or TestNG standard test and can be easily run in an integration test within a CI/CD pipeline. Kamelets are Camel-K route snippets which act as event sources and sinks in an event-driven architecture.

Using the most popular Page Objects template, you can describe all page objects. To describe specific pages for your app (Web, IOS and Android), you can reuse the Custom Type Page Factory. You can make a cool test by adding Verification Logic to your combined PageObjects. That's it. We support Data Driven Approach as we want you to get the data you need from any source. You can have your test run on both Android and IOS platforms by adding some platform specifics. Code will be reused at 80% avg. There are many options for test execution. You can use either local or CI environments. You can also include multiple platforms and have reports sent to multiple third-party tools. The best part is that you can use any external or internal Selenium Hub Providers such as SauceLabs BrowserStack, TestingBot, Zebrunner Engine, SauceLabs and BrowserStack. Multithreading allows you to quickly get the testing results.

Spock is a specification and testing framework for Java and Groovy apps. Its beautiful and expressive specification language is what makes it stand out among the rest. Spock can be used with all IDEs, build tools and continuous integration servers thanks to its JUnit runner. Spock was inspired by JUnit, RSpec and jMock. Spock Web Console allows you to view, edit, run and publish Spock specifications instantly. It's the ideal place to play with Spock without any commitments.

Gauge is an open-source framework that allows you to write and run acceptance tests. Gauge tests can be written in Markdown, which makes it easier to maintain and write them. Reuse specifications and robust, refactoring will reduce duplication. A test suite that is less code and has readable specifications will save you time and effort. Gauge can be used with multiple languages, CI/CD tools, and automation drivers. To get your test automation tool working for you, you don't need to learn a new language. Gauge's plugin architecture and ecosystem is robust. Gauge can be easily extended to support IDEs, drivers and datasources. Do not waste your time looking through stacktraces. Gauge will take a screenshot of a test failure to give you a clear picture of what went wrong. Reports can be accessed in multiple formats (XML and JSON, HTML).
