    Karate

    Karate

    Karate

    Karate is the only open-source tool to combine API test automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. There’s also a cross-platform stand-alone executable for teams not comfortable with Java. You don’t have to compile code. Just write tests in a simple, readable syntax - carefully designed for HTTP, JSON, GraphQL and XML. And you can mix API and UI test automation within the same test script. It is worth pointing out that JSON is a ‘first-class citizen’ of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes. There is no need to ‘escape’ characters like you would have had to in Java or other programming languages.

    EarlGrey

    EarlGrey

    EarlGrey

    With the EarlGrey framework, you have access to enhanced synchronization features. EarlGrey automatically synchronizes with the UI, network requests, and various queues; but still allows you to manually implement customized timings, if needed. EarlGrey’s synchronization features help to ensure that the UI is in a steady state before actions are performed. This greatly increases test stability and makes tests highly repeatable. EarlGrey works in conjunction with the XCTest framework and integrates with Xcode’s Test Navigator so you can run tests directly from Xcode or the command line (using xcodebuild). The EarlGrey documentation for users is located in the EarlGrey/docs folder. To get started, review the EarlGrey features, check for backward compatibility, and then install/run EarlGrey with your test target. After everything is configured, take a look at the EarlGrey API and start writing your own tests.

    Serenity BDD

    Serenity BDD

    Serenity BDD

    Serenity BDD helps you write cleaner and more maintainable automated acceptance and regression tests faster. Serenity also uses the test results to produce illustrated, narrative reports that document and describe what your application does and how it works. Serenity tells you not only what tests have been executed, but more importantly, what requirements have been tested. One key advantage of using Serenity BDD is that you do not have to invest time in building and maintaining your own automation framework. The aim of Serenity is to make it easy to quickly write well-structured, maintainable automated acceptance criteria, using your favourite BDD or conventional testing library. You can work with Behaviour-Driven-Development tools like Cucumber or JBehave, or simply use JUnit. You can integrate with requirements stored in an external source (such as JIRA or any other test cases management tool), or just use a simple directory-based approach to organise your requirements.

    Galen Framework

    Galen Framework

    Galen Framework

    Layout testing seemed always a complex task. Galen Framework offers a simple solution: test location of objects relatively to each other on page. Using a special syntax and comprehensive rules you can describe any layout you can imagine. Galen Framework runs well in Selenium Grid. You can set up your tests to run in a cloud like LambdaTest, or Sauce Labs, or BrowserStack so that you can even test your responsive websites on different mobile devices. Galen can run multiple tests in parallel which is also a nice time saver. Galen Framework is designed with responsiveness in mind. It is easy to set up a test for different browser sizes. Galen just opens a browser, resizes it to a defined size and then tests the page according to specifications. Using Galen Specs Language you are able to describe any complex layout including different screen sizes or browsers. It's not only easy to write, it is also easy to read it if you are unfamiliar with the language.

    behave

    behave

    Behavior-driven development (or BDD) is an agile software development technique that encourages collaboration between developers, QA and non-technical or business participants in a software project. We have a page further describing this philosophy. Behavior-driven development (or BDD) is an agile software development technique that encourages collaboration between developers, QA and non-technical or business participants in a software project. It was originally named in 2003 by Dan North as a response to test-driven development (TDD), including acceptance test or customer test driven development practices as found in extreme programming. BDD is a second-generation, outside–in, pull-based, multiple-stakeholder, multiple-scale, high-automation, agile methodology. It describes a cycle of interactions with well-defined outputs, resulting in the delivery of working, tested software that matters.

    Selenide

    Selenide

    Selenide

    You don't need to think how to shut down browser, handle timeouts and StaleElement Exceptions or search for relevant log lines, debugging your tests. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. Selenium WebDriver is a great tool, but it’s not a tool for testing. It’s a tool for browser manipulation. There are several testing libraries around Selenium WebDriver. But it seems that they do not resolve the main problems of UI tests. Namely, instability of tests caused by dynamic content, JavaScript, Ajax, timeouts etc. Selenide was created to resolve these problems. First of all, Selenide makes your tests stable by resolving (almost) all Ajax/timing issues. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. The whole work with Selenide consists of three simple things!

    StepZen

    StepZen

    StepZen

    StepZen provides a unique low code approach to creating GraphQL APIs for any data source—REST, SQL, NoSQL, SOAP/XML, and GraphQL. With one command, you can specify your backend; StepZen introspects it and generates the schema for you. Then, with a few lines of code and powerful directives (@rest, @dbquery), you can quickly customize a schema—or write one from scratch. Another directive (@materializer) lets you stitch graphs together, seamlessly scaling GraphQL across teams and domains. In addition, by using @materializer, you avoid managing concerns across subgraphs, writing stubs of types, and other complexities. Whether you deploy a single graph or a federated graph-of-graphs, with one command, you deploy it to StepZen's highly available cloud. Automatic parallelized execution, security and control of your APIs and data, and performance and reliability optimizations are built-in. So we keep your GraphQL infrastructure secure and stable so you can focus on your business.

    Elixir

    Elixir

    Elixir

    Elixir is a dynamic, functional language for building scalable and maintainable applications. Elixir leverages the Erlang VM, known for running low-latency, distributed, and fault-tolerant systems. Elixir is successfully used in web development, embedded software, data ingestion, and multimedia processing, across a wide range of industries. Check our getting started guide and our learning page to begin your journey with Elixir. All Elixir code runs inside lightweight threads of execution (called processes) that are isolated and exchange information via messages. Due to their lightweight nature, it is not uncommon to have hundreds of thousands of processes running concurrently in the same machine. Isolation allows processes to be garbage collected independently, reducing system-wide pauses, and using all machine resources as efficiently as possible (vertical scaling). Processes are also able to communicate with other processes running on different machines in the same network.

    Forth

    Forth, the computer language was created for programming embedded and real-time applications. Today, it is available for developing applications on Windows, DOS, and variants of Unix that include macOS. Additionally, commercial-grade Forth cross-compilers generate highly optimized code that runs on a variety of microprocessors and microcontrollers and proves themselves very capable in custom-hardware environments. Forth is a high-level programming language, although most versions include an assembler. Fourth-system providers often include software tools to help application code make good use of system resources. Forth is interactive. It is conducive to developing modular, well-tested code in shorter development times. It can also result in very concise code. Some programmers are not accustomed to languages with such brevity, directness, and (apparent) simplicity. Forth has a reputation for rapid development, lean code, and superb performance.
