The success and failure times of performance test results are inaccurate

[mashuangwei]

1. Describe the bug 🐞

The success and failure times of each performance test result are inaccurate. For example, my pressure test interface inserts data. After 5 minutes of performance test, the performance test result succeeds 30000 times, and 30000 pieces of data are not inserted into the actual database. The same problem applies to the number of failures.

A clear and concise description of what the bug is.

2. Reproduction steps

1. Create performance test plan

2. Perform a 5-minute test

3. Check the performance test results to verify whether the success and failure times are accurate'

3. Environment

• Controller
  • OS: centos7
  • Browser: chrome 93
  • JDK version: 8
  • Controller version: 3.5.5 && 3.5.5-p

4. Screenshots

If necessary, add screenshots to help explain your problem.

I think it's not the bug but your script problem.
To be clear, please post the script you used.

I think it's not the bug but your script problem. To be clear, please post the script you used.
It should be a defect. The test report shows that the number of executions is 23835, and the actual amount of data inserted into the application database is 24369. That is, the number of executions shown in the test report is less than the actual number
