5 Open Source Web Testing Tools

JMeter

JMeter is an open-source pure Java-based application used to test and measure the performance and load. It comes with a beautiful user-friendly Graphical User Interface (GUI). Through GUI you can test and debug quickly. By using this tool testing can be done on static and dynamic resources such as Perl Scripts, Java Objects, files, Database, Queries, Servlets, FTP server, etc. Statistics of severe load can be select through the pluggable timer. It can be used to test the performance of different loads by simulating a load on the server. It provides personalization and extensibility through data analysis plugins.

Grinder

The grinder is an open-source Java-based load testing framework. It is a very easy-to-run web testing tool that used different injector machines. This tool was developed by Paco Gomez and is maintained by Philip Aston. The grinder has two main parts, one is Grinder Console and the second is Grinder Agents. Grinder Console is based on Graphical User Interface(GUI) and it is used to monitor the real-time results and control the number of agents. Grinder Agents are headless load generators. The main purpose of these headless agents to create the load through a number of workers. It used TCP proxy to record the network activities and save this activity into the Grinder test script. By using this you can increase the number of agent instances.

Multi-Mechanize

Multi-Mechanize is an open-source framework used for load testing and web performance. This web testing tool used simultaneous Python scripts to produced load against the website or web service. This web testing tool we commonly used for scalability testing and for web performance. It is a very scalable tool it can also be used to produced workload against remote API accessible from Python. Report of test output is saved as an HTML. It is a free tool and runs on multiple frameworks. The code of this tool is written in Python and it automatically generates reports. To generate simultaneous virtual users it used a multi-process and multi-thread engine.

Selenium

Selenium is an open-source portable software testing framework for web applications. We can say that it is used for testing web applications and automates browsers. It is used for cross-platform like Windows, Linux, and Macintosh. Selenium provides a record playback tool for testing and no need to learn scripting language. It can be deployed on Firefox extension and provide the facility to edit, record and debug tests. It also provides the API and gives the facility of tests that can be written in various programming languages like Java, C#, Groovy, Perl, PHP, Python, and Ruby. Selenium Grid server allows you to test web browser instances running on remote machines. It has been released under the Apache 2.0 license.

OpenSTA

OpenSTA is an open-source web-based testing architecture tool. It is used to perform scripted HTTP and HTTPS load tests with performance measurements. It is run on Window based operating systems. Scripts are written in SCL language.SCL is a proprietary language and it is a very simple language which supports different function and variable scopes. By using this web tool you can gather statistics and results by automatic and through user-controlled mechanisms. Because OpenSTA is free and open-source and its source code is publicly open and available on the SourceForge site. It provides the freedom to customize OpenSTA according to your needs. It has been released under GNU General Public License 2.0.
