Selenium offers superb compatibility with various popular browsers, operating systems and programming languages. It comes with a wide range of libraries containing different languages and commands from Selenium API. It also supports various testing frameworks like FluentLenium, QAF, Capybara, etc.
You can add Selenium IDE to your browser extension and employ ultrafast bug identification without even learning any scripting language. Besides, you can run performance software testing on several machines and manage them from a central point.
WatiN
Written in C#, WatiN allows you to test web applications through browsers with ease. Since it is a .NET library, you can develop your own test project using .Net compatible language. Watin offers better features than other .NET solutions, making it a popular user interface and user acceptance testing tool.
Watin uses DOM manipulation through browser interaction. However, Watin 2.0 supports writing crossbrowser tests. Writing tests is a time-consuming task; it comes with a feature to record tests for future reference. Moreover, it supports both modal and modeless HTML dialogs and frames like iframes and cross-domain.
Appium
Appium framework is an excellent tool for mobile apps that covers both native and hybrid applications but running it requires some development skills. Its cross-platform supports makes it perfect for performance testing for Android, iOS and windows. It features a web driver API that allows you to run a web driver API for multiple test runners and frameworks. It further comes with adaptable HTTP client libraries with extended APIs support for testing apps in a mobile environment.
JMeter Testing Tool
Apache JMeter is a java-based load testing tool developed with an initial intention to run a test web application, later expanded to test other applications. Not only it supports testing static and dynamic resources, but it also allows testing of dynamic web applications. It features a command-line mode, allowing you to load tests from any java compatible OS such as Windows, Mac OS, Linux, etc.
Thanks to its visualization plugins, you can customize Jmeter for your various business requirements. Made from a multithreading framework, it supports simultaneous function sampling across a diverse range of threads. Moreover, the caching feature allows you to cache test results, display and replay them offline.
OpenTest
As the name suggests, OpenText is used for automated testing of web-based programs, mobile apps, and APIs. Thanks to its user-friendly interface, you don’t need to learn any coding skills to use it. On top of it, it supports all popular web browsers and supports cloud servers to execute multiple test cases.
Its keyword testing feature allows you to implement unique keywords on test cases, reducing test complexity and increasing maintainability. Its HTTP API will enable you to integrate your code with third-party applications like Jira, Jenkins, etc. Besides, you can embed your javascript codes anywhere in your test that helps to deal with complex scenarios.
Gatling
Gatling open-source test automation tool is better used for detecting errors in the early stage of the software development cycle. Its superb source code can predict whether a test case would crash or not adhered to its response time. It offers a simulation of millions of users and essential utilities such as recording test playback, reports, etc. Although it comes laden with advanced metrics and automation features, this tool is not a complex affair.
Citrus Framework
If you need a test management tool that simulates both the client and the server, then the citrus framework is the right tool for you. It is highly beneficial for complex integration testing such as force crashing and timeout. It supports extensive database content for executing queries in database tests. Further, it allows you to send and receive control messages for validation and save the message content for reuse.
Citrus open-source test management tool acts upon both the client and the server simulating request during the test run. This tool is helpful for complex integration testing involving the force crashing and timeout situation.
WebDriverIO
WebdriverIO is a javascript-based testing tool for mobile apps and browsers. It uses Webdriver protocol, allowing you to perform across various popular browsers. You can automate applications written in angular and polymer frameworks and integrate an extensive range of community plugins as per your business needs.
