Needs analysis
1, in a stepped ramp, threads measuring performance during compression, since the polymerization results are reported to generate a summary of the results of sub-step mode is not the measurement results are summarized pressure, which causes the polymerization can not compare different reports generated in accordance with step mode, TPS, in response to the actual, the error trend
2, the above requirements, it is necessary to achieve the following effects, such as 1 to 50 concurrent users to the current pressure measurement results are summarized in a thread group to 1-50, 51-100 concurrent pressure measured at the user, the current pressure measurement results are summarized in the 51-100 thread group
3, after careful study, the effect can be achieved by getting the currently active thread, this demo uses 15 threads
First, add a ladder thread group
- Test Plan "add" Threads "jp @ gc - Stepping Thread Group (deprecated)
- Thread ladder mode specific settings
- Right-click the Thread Group "Add" Sample "BeanShell Sampler
- The realization of java statements to obtain the total number of active threads, and then assigned to a thread based on the total number of active threads, and finally to the transaction name calling, java statement is as follows
- The realization of java statements to obtain the total number of active threads, and then assigned to a thread based on the total number of active threads, and finally to the transaction name calling, java statement is as follows
- Then add various requests, the transaction request is placed in a controller, the controller calls the transaction variable
Second, perform pressure measurement task
1, this pressing load measured using 30S 5 per user, total of 15 users, perform the following results- 1-5 concurrent users of real-time results
- 6-10 concurrent users of real-time results
- 11-15 concurrent users of real-time results
- According to the log output, you can know that this effect in line with expectations
- 1-5 concurrent users of real-time results
