Demand analysis

1. In the process of step-by-step incremental performance stress testing using step-by-step threads, because the result generated by the aggregation report is a summary result, the test results will not be summarized in step-by-step mode, which leads to the failure to compare the changing trends of tps, response reality and error under different step-by-step modes according to the generated aggregation report.

2. Based on the above requirements, the following effects need to be achieved. For example, under 1-50 concurrent users, the current stress test results are summarized into 1-50 thread groups, and under 51-100 concurrent users, the current stress test results are summarized into 51-100 thread groups.

3. After research, this effect can be achieved by getting the current active thread. This demonstration uses 15 threads.

Add a ladder thread group

Test Plan "add" Threads "jp@gc-Stepping Thread Group (deprecated)

Ladder mode specific thread setting

Right-click the thread group "add" Sample "BeanShell Sampler this time's java statement to get the total number of active threads, then assign a value to a thread based on the total number of active threads, and finally call the transaction name. The java statement is as follows

Then add various requests and place them in a transaction controller, which invokes the variable

2. Perform pressure test tasks

1. This stress test uses 5 users per 30s for a total of 15 users. The execution results are as follows: real-time results with 1-5 users

Real-time results with 6-10 concurrent users

Real-time results with concurrent users of 11-15

According to the output log, we can know that the effect is in line with the expectation.
