Performance Testing is the process of determining the speed, effectiveness, reliability, scalability and interoperability of the system, computer, network, program or application. The process can also check two or more application to compare system speed, data transfer rate, bandwidth, efficiency, and reliability.
Below is a hand-picked list of Top Web Performance Testing Tools-
1) LoadUI Pro
LoadUI Pro by Smartbear allows you to quickly create scriptless sophisticated load tests, distribute them on cloud using load agents and monitor performance of your servers as you increase load on them. You can access detailed reports and quickly automate your load tests on Jenkins, Bamboo, TFS and other automation frameworks – If you are using SoapUI already, you can convert the test cases into load tests with just 3 clicks– all without writing a single line of script.
- Scriptless Load test creation
- Preconfigured load test templates like spike, baseline, stress, smoke
- Drag and drop load tests on distribution agents on cloud
- Sophisticated analytics and statists features for reporting
- Quick conversion of functional tests from SoapUI as load tests
- HTTP, REST, SOAP, JSON ,JMS, Swagger, RAML , IODocs,
- API Blueprint, JSON Schema, XML Schema, MQTT, CoAP, WSDL,WADL
StresStimulus targets application scenarios that are difficult to test with other tools. It automatically fixes playback errors thanks to its proprietary autocorrelation. StresStimulus records user actions and replays them to emulate variable usage patterns. It also monitors load impact on application responsiveness and server infrastructure. The result analyzer finds hidden concurrency errors left unexposed by functional testing and includes detailed application performance metrics.
- End-to-end Test Wizard covers all steps from recording to test results, which reduces the learning curve
- On-premise or cloud testing supported with multiple load generators
- Works as a stand-alone tool or Fiddler add-on
- Exports script to Visual Studio test format to help with scenarios that fail when recorded in Visual Studio directly
- Manual scripting is not required but available; supports three scripting languages
3) Load View
LoadView by Dotcom-Monitor is a powerful, cloud-based load testing tool that uses real browsers to load test your website or web application and can perform testing that scales to thousands of simultaneous users. The test results are recorded, aggregated and available in real-time online graphs. It provides detailed reports to help track the response time of your website as the number of simultaneous users increases. One major difference between LoadView and most other load testing tools is the ability to run multi-step, scripted user interactions using a real browser.
- Create tasks that range from simple calls to download content, to complex interactions simulating real users interacting with your web application
- Record dynamic scripts with no coding knowledge using the EveryStep Scripting Tool
- Over 40 different browsers, you can choose from to record a script that also includes mobile devices
- Real-time results that include session wise data on individual page and session response times
Browser Web Transitions, JS, HTTP, HTTPS, REST, SOAP, JSON, XML, WebSocket, WebAPI
NeoLoad is an innovative performance testing platform designed to automate test design, maintenance, and analysis for Agile and DevOps teams. NeoLoad integrates with continuous delivery pipelines to support performance testing across the life cycle - from component to the full system-wide load tests.
- Automated test design enabling 10x faster test creation and update than traditional solutions
- Integration with CI servers for automated test runtime
- Collaboration: shared test scripts and reports, in real -time and after test completion through an on-premise or SaaS web interface
- Hybrid on-premise and cloud load generation from over 70 global localizations
5) Apache Jmeter
JMeter is an open source tool that can be used for performance and load testing for analyzing and measuring the performance of a variety of services. This tools mainly used for web and web service applications.
This tool doesn't demand state of the art infrastructure for load testing and supports multiple load injectors managed by a single controller
