nGrinder is a platform for stress tests that enables you to execute script creation, test execution, monitoring, and result report generator simultaneously. The open-source nGrinder offers easy ways to conduct stress tests by eliminating inconveniences and providing integrated environments.

Want to know what's changed from the original grinder platform?

You can find out what nGrinder looks like with screen-shot.

nGrinder consists of two major components.

  • a web application that enables the performance tester to create a test script and configure a test run

nGrinder agent

  • a virtual user generator that creates loads.

Features

  • Use Jython script to create test scenario and generate stress in JVM using multiple agents.
  • Extend tests with custom libraries(jar, py). It's unlimited practically.
  • Provide web-based interface for project management, monitoring, result management and report management.
  • Run multiple tests concurrently. Assign the pre-installed multiple agents to maximize each agent's utilization.
  • Deploy agents on multiple network regions. Execute tests on various network locations
  • Embed Subversion to manage scripts.
  • Allow to monitor the state of agents generating stress and target machines receiving stress
  • Proven solution which is used to test huge systems having more than 100 million users in NHN.
