LoadRunner is a performance testing software, through the simulation of real user behavior, through the load, concurrency and performance of real-time monitoring and completion of the test report, analysis of the system may exist bottlenecks, LoadRunner one of the most effective means is concurrency control, through the console settings, In order to achieve the same business while simulating thousands of users to operate. We can see that LR is a software owned by HP, and the software belongs to the commercial software, as a commercial software, LR is very powerful in terms of functionality, especially test report after testing and real-time monitoring of performance is very good, the small part of the trial version here for everyone to explain.

After the installation completes LoadRunner enters the LoadRunner initial interface, first makes a simple introduction to this interface: On the left side of the interface has three items respectively, Create/edit scripts creates or edits the script, Before you introduce the LR is a performance testing software simulating user behavior, then how to simulate it? Of course, it is by recording the script, so that the operator can do whatever they want to record the operation. Create a script below run load tests literally everyone should guess is running a load test, how to run the load test, which requires the pre-recorded script. At the bottom of the test results are analyzed for analyze test results, so readers are aware of the three major steps of performance testing, namely, business recording, load running, and result analysis?
