• Data visualization and analysis plugins for personalization and extensibility
• Functions to provide dynamic test input or data manipulation
• Scriptable samplers in JSR223-compatible and BSF-compatible languages

3. HP LoadRunner

Hewlett Packard’s LoadRunner is a purchasable web performance testing tool that can 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 enables you to gather all performance-related and infrastructure-based information.

LoadRunner consists of various separate tools: Virtual User Generator, Load Generator and Analysis, and Controller. It works by creating a scenario that contains the script that is to be executed. The number of virtual users needed is also generated, along with other prerequisites for running the test and generating the expected results. The number of virtual users to be 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 series of actions to be performed are recorded onto the virtual user script. A load generator is then used to run the users, generating the necessary level of 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.

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 their web applications can accommodate the required user loads.

5. NeoLoad

NeoLoad by France-based Netosys is a Java-based web performance testing tool that can be used for measuring and analyzing a website’s performance. It can also be used to analyze further steps to be taken 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 performance of the application under heavy load. You get to understand the capacity of the application and how many users it can handle simultaneously. Written in Java, NeoLoad is available in French and English. It simulates user activity in web and mobile applications as well, and monitors the infrastructure behavior. You can choose from cloud-based load generators for the performance test.
