JMeter - Stop thread after error, but allow retries

Question

I have a JMeter script which makes requests to 5 different endpoints. If there's an error, that thread should be stopped.

However, I would like to retry the request to the 3rd endpoint 3 times before stopping the thread.

Here is what my script looks like:

Thread Group (with Stop thread selected)
- HTTP Request (1st endpoint)
- HTTP Request (2nd endpoint)
- Transaction Controller
  - While Controller
    - HTTP Request (3rd endpoint)
      - JSR223 PostProcessor (to save the response code in a variable for the while controller to check)
    - Counter (to keep track of the retry count)
  - JSR223 Assertion (to set the result as successful, so the first failed retries don't count)
- HTTP Request (4th endpoint)
- HTTP Request (5th endpoint)

Since I checked option Stop thread under Thread Group, if the first request to the 3rd endpoint fails, the thread stops and no retries are made.

If I check Continue, then the retries to the 3rd endpoint work as intended, but the thread doesn't stop if the requests to the other endpoints fail.

I also tried to add the following Groovy script to the JSR223 PostProcessor, but it didn't work:

if (prev.isStopThread()) {
    prev.setStopThread(false)
}

I'd appreciate any help I can get.

Thank you!

Just set "Action to be taken after a Sampler error" to Continue in the Thread Group to prevent threads from stopping.

If you decide to stop the thread you can do it in 2 ways:

Via Flow Control Action Sampler (in conjunction with the If Controller)
Via any of your JSR223 Test Elements as
```
prev.setStopThread(true)
```

You don't even need a counter, since JMeter 5.0 While Controller exposes current iteration via __jm__While Controller__idx pre-defined variable
