![]() ![]() The open source tool delivers results and statistics during test runs through a variety of automatic and user controlled mechanisms such as scripted timers, SNMP data, Windows Performance Monitor stats and HTTP results & timings. ![]() The tool has been developed to help testers detect deadlocks and slowdowns in web applications and has the capability to scale up testing across several servers.įreely available under the GNU GPL license, OpenSTA is designed for undertaking scripted HTTP and HTTPS heavy load tests with performance measurements from Win32 platforms. The latest version of the open source tool supports arbitrary branching and looping, makes test results directly available to the test script, supports multiple protocols, and enables flexible parameterization. Who is it for? The Grinder is best suited for web application testers who prefer using dynamic test scripts to carry out load testing. Test scripts on The Grinder can be written in Jython and Clojure and the tool supports distributed tests using many load injector machines but with centralized script editing and distribution.

The fact that it is compatible with all major browsers such as Chrome, Safari, Firefox, Microsoft Edge, and Opera has powered widespread adoption of Selenium by developers worldwide. Developers can customize the code to modify predefined functions and classes to add new test parameters as per their requirements. Who is it for? Selenium is perfect for testers and developers who need to web-test hundreds of websites within a short timeframe. As a standalone open source tool, Selenium lets web testers write test scripts in Ruby, Java, NodeJS, PHP, Perl, Python, C#, and other programming languages which are then run by the Selenium WebDriver automatically. ![]() It saves enormous time and resources in terms of running hundreds of tests and pinpointing the source of errors and bugs. Automation testing has become commonplace now as it helps automate repetitive testing tasks and runs test scripts automatically to compare actual performance results of applications with expected results. Selenium is the leading open source tool for automation testing web browsers and applications. Who is it for? Available on an Apache license and working at the protocol level, JMeter runs as a desktop application, helping web testers carry out automated functional testing, create test plans using text editors, measure the performance of web applications using graphs and tables, and regression testing applications by creating test scripts with assertions. Among its principal features is the ability to extract data from HTML, JSON, XML or any textual format and the ability to load tests from Java-compatible operating systems such as Linux, Windows, and Mac OSX. Based on Java, it simulates heavy loads on groups of servers, and networks to test the performance of applications. JMeter is the most popular and widely-used open source tool for load testing web applications and analyzing the overall performance of applications under different load types. With open source being the key disruptive factor, we list down top 10 open source web testing tools for 2020 based on key features, use cases and developer adoption that every QA engineer and tester should know. Of late, web testing has evolved to cover connected devices with IoT testing expected to become a $1.3 billion industry by 2021. Modern web testing tools are used for testing the functionality, security, usability, and accessibility of websites and applications.
