Let me analyze of how distributed load testing can be done with a handy tool, AdventNet QEngine 6.9. As quality matters everywhere high attention has to be paid in those areas. As far as an application, few metrics have to taken into account before delivered into the market. Response time analysis and load capacity of the application must be done. We cannot make calculation over rough paper for these metrics manually everytime. Suppose if the application is to be tested with load capacity of 5 users, we can try for it. What happens when we need to load test the application for 1000 or 10000 users?. Testing tool like LoadRunner, QEngine, Neoload etc., can be helpful in this scenario. QEngine costs low comparing with other competitors. The tool is user-friendly too. Let me analyze on the tool QEngine of how to distribute the load test of your application in your environment. Let us assume, you have purchased the license of 5000 Virtual User on QEngine and you have to test your application with 5000 user load. You cannot go with testing such high load on a single server machine. You can install the license on the server machine and the virtual user load can be distributed through several machines(Agents). The recommended Virtual user configuration from QEngine for a 1GB machine is 500 virtual users. The agent has to be configured in the server machine with their IP address and Load test user credential. The Distributed agent has to be started from the configured agents by selecting the ‘Start -> Programs >AdventNet QEngine WebPerformance -> Start Distributed Agent’.After starting the distributed agents in all agents, the application which was recorded previously configured with Virtual user specification can be load tested by hitting the ‘Start Load Test’ button.
Hope this discussion help you,
