Performance testing tools are indispensable to ensure that an application performs well. A good performance tester must have the ability to put stress on the tested application, to observe its behavior under adverse conditions, and to respond quickly to changes in the tested application’s behavior. Performance testing is crucial for avoiding unpleasant surprises at launch time. These best open source performance testing tools for web applications will help you perform effective tests of your applications.
This document is a collection of the best open source performance testing tools for web applications. It is designed to be a practical guide to help engineers and architects find, evaluate and install appropriate tools on a limited budget or schedule.
nGrinder
nGrinder has been developed to be one of the enterprise-level performance engineering solutions. It was created to make stress testing simple and to offer a platform that offers you to develop, perform and observe tests. The main features are:
· Automatic gathering test outcomes from distributed agents after tests
· Permits you to observe the condition of your performance agents load generation
· Prolong test with customer libraries such as py and jar
· You can scribble your tests incorporating Groovy and Jython
LoadView
This is very famous for performance testing services. This is a completely managed and on-demand stress testing and load testing tool. This is very different from the other load testing tools. In this tool, testing is done in real browsers. The outcome is close emulation of highly accurate and actual user data. It permits developing multi-step scripts pretending user interaction with website or app. Some of the key features are:
· Backs advanced loading features such as real browser testing, click scripting, and cloud-based infrastructure
· Permits easy and immediate development of test scripts without coding requirement
· Backs rich internet apps incorporating PHMP, Silverlight, Ruby, HTML5, Flash, and Java
· More than twelve worldwide cloud locations supported by Amazon web services and cloud platform
· Dzone has test compatibility with browsers, mobile devices, and desktops
· Simple to share performance reports and metrics
· Pinpoint bottleneck and backs scalability
Taurus
This tool plays an imperative role in hiding the difficulties related to performance testing. The power of this tool enables you to write your tests in YAML.
This helps you to describe a completely blown script in approximately ten lines. This provides teams the ability to elaborate tests in JSON or YAML files. YAML is edible readable and human that allows you to explain a test in an easy text file. The main features are:
· Permits more members of your team to participate in performance tests. In addition to this, your test cases are written in YAML. Hence, the tests are comparatively very readable. This makes it easier to perform code reviews.
· Taurus fundamentally embeds performance testing in the continuous integration and the continuous delivery pipeline in a much efficient manner.
· Taurus offers a type of abstraction layer on top of JMeter and other tools like Selenium, Grinder, Gatling, and Locust.
Load Impact – LoadImpact, soon to rebrand as k6 Cloud, is a cloud service used to load test the performance of websites, apps, and APIs
LoadImpact is a cloud service to load test the performance of websites, apps, and APIs that has specifically focused on API load testing in the new k6.io app, with a completely revamped Test Builder. Plus, they have an improved browser session recorder and an improved results page.
A standout component of this software is it’s easy to support of various ‘cl technologies’. Additionally, the reporting, graphs, and pictures are aesthetically pleasing and very readable.
This tool would benefit in some better help sections/training documents in order to outline the different components of the software and website. They lost a few marks in the evaluation for Usability but this certainly isn’t a deal-breaker, as many aspects of the tool are intuitive anyways.
Load Impact starts at $99/month and has a free trial.
LoadFocus – No-code testing to find out how many users your website or API can handle; easily run tests within the browser from multiple locations
An easy and cost-effective way to test your websites, mobile and web applications, web services and APIs with features like load testing, website speed testing, mobile emulation, automated website testing, SEO/PWA/speed monitoring, and software consultancy services.
LoadFocus has a very reasonable price-per-month, scoring them favorably in the Value for Cost section of the evaluation review as far as paid load testing tools are concerned.
One weakness of the tool is that communication between the user and the LF team could be clearer and better implemented. For example, there have been some complaints about not receiving confirmation emails and other expected communication items.
LoadFocus starts at $22.60/month and has a free 14-day trial.
Parasoft Load Test – Load testing module that enables users to take SOAtest functional test projects and leverage them for performance testing
Parasoft Load Test enables users to take SOAtest functional test projects and leverage them for performance testing. The Load Test Continuum (LTC) web-based reporting app makes performance testing a part of the CI/CD process and implements performance test automation.
One of the best parts of the software is that minimal experience/training is needed to get started. Users can easily pull from Excel or XML files, as well, and automating the APIs is intuitive.
With a rather hefty up-front cost, Parasoft Load Test lost a few marks in the Value for Cost section of the evaluation criteria, as the price tag may deter some. It is important to note that the cost listed below includes the enterprise edition, desktop licenses, and training for a team of 5.
Parasoft Load Test starts at $50,000 and has a free trial.
SmartMeter.io
SmartMeter.io is the preferred option for performance testing services who want to address the drawbacks of JMeter. The tool supports the creation of a simple scriptless test environment with its Recorder. It provides test reports and has features like automatic test criteria assessment and test runs trend and comparison analysis. The tool offers full support for CI/CD integration. Its key features are as follows:
- Create a scriptless test environment
- Advanced response body extractor
- Real-time results and GUI test runs
- Comprehensive reporting, automatic assessment, and test execution comparisons
- Supports CI/CD integration
The SmartMeter.io supports the following protocols – HTTP, FTP, LDAP, JDBC, JMS, and SOAP. There is no need for browser plugin or proxy setup. It has excellent capabilities in CI integration, distributed testing, and provides unmatched performance testing support when it comes to validating apps.
Conclusion
Performance testing tools is very important for web application performance and the most important thing that we want for them is getting better results. different tests can be categorized into two major types they are load testing tools and stress testing tools. The best open source performance testing tools which i am going to describe in this article makes my work easy and convenient and I can perform my test quickly and with better results.
