3. HP LoadRunner
Hewlett Packard’s LoadRunner is a purchasable web performance testing tool to understand and determine the performance of a system under load. A key advantage of this tool is that it can handle and generate thousands of users simultaneously. It also enables you to gather all performance-related and infrastructure-based information.
LoadRunner consists of various tools: Virtual User Generator, Load Generator and Analysis, and Controller. It works by creating a scenario containing the script to run. The number of virtual users and other prerequisites for running the test and generating the expected results are also determined. The number of virtual users generated could range from a few hundred to a few thousand.
The scenario could be manual or goal-oriented, in which the tool automatically generates the scenarios based on previously specified goals by the tester. The virtual user script records the action to perform. A load generator runs the users, generating the necessary load on the system. The processes to be measured are represented as transactions. Once the load is generated, the system behavior is monitored and analyzed.
4. Rational Web Performance Tester
The Rational Performance Tester from IBM is an automated web performance testing tool for web and server-based applications. There is an input and output process in this tool. The tool generates a demo of the original transaction process, gathering and analyzing statistical information to increase efficiency. This tool identifies and rectifies any server or website leakage for creating an error-free, effective cloud computing service.
The tool can identify the presence and root cause of bottlenecks in system performance. It combines several ease-of-use features along with detailed analysis, simplifying test creation, lead generation, and data collection processes to ensure that its web applications can accommodate the required user loads.
NeoLoad by France-based Netosys is a Java-based web performance testing tool that measures and analyzes a website’s performance. It analyzes further steps to take based on the performance of the website and end result of the tests. This, in turn, helps improve and optimize the performance of your web application.
The tool works by increasing the traffic on your website and then analyzing the application’s performance under heavy load. You get to understand the application’s capacity and how many users it can handle simultaneously. Written in Java, NeoLoad is available in French and English. It also simulates user activity in web and mobile applications and monitors the infrastructure behavior. You can choose from cloud-based load generators for the performance test.
NeoLoad can be used for automating the complete Web 2.0 suite, which includes Flex, Silver Light, Web Services, Web, and Multimedia. The user can determine the number of load generators needed and the LAN’s LGs. They can also choose to simulate 2G-4G and WiFi mobile networks with variations in signal strengths.
This tool integrates with third-party tools like Dynatrace, App Dynamics, Introscope, and Site Scorpion for a deep dive analysis on servers. However, SLA configuration is unavailable on this tool for analyzing the results. Ultimately, it is a performance-testing solution for mobile and web applications that can be used for running cloud-based tests. If you or your performance team need a tool to analyze and co-relate test results with raw data, NeoLoad would be a great choice. The tool is compatible with operating systems Solaris, Linux, and Windows.
The next open source stress test and web performance testing tool in this list is LoadUI, yet again for measuring the performance of a web application. The tool works well when integrated with the soap UI functional testing tool. It is one of the most interactive and flexible testing tools. This tool allows you to create, update, and configure your application during testing. It gives a visual aid tool for the user with a drag-and-drop feature.
LoadUI is far from a static performance tool. It offers advanced features for generating reports and analysis. You can also examine the actual performance of the web application by adding new data even as the application is being tested. You do not have to restart the tool every time you change or modify the application. LoadUI is automatically updated in the interface. It is a cross-platform tool that should work for any major operating system. In fact, it is also free to use.
This web performance testing tool is for intranet applications and websites. WAPT is short for Web Application Performance Tool, and it acts as a scale or analyzing tool for measuring the output and performance of a web application and related interface.
