I am following the getting starting steps and running the first test

I have local config file setup for my pi zerow:

targets:
  main:
    resources:
      RawSerialPort:
        port: "/dev/ttyUSB0"
    drivers:
      ManualPowerDriver:
        name: "example"
      SerialDriver: {}
      ShellDriver:
        prompt: 'pi@\w+:[^ ]+ '
        login_prompt: 'raspberrypi login: '
        username: 'pi'
        password: 'password'

I have verified the port /dev/ttyUSB0 is correct using dmesg

When I run the test using:

pytest --lg-env local.yaml test_shell.py

I consistently get this timeout error:

**ERROR test_shell.py::test_shell - pexpect.exceptions.TIMEOUT: Timeout of 4.93 seconds exceeded or connection closed by peer**

I also see this error in dmesg after test is run (bold):

[670927.706302] usb 1-7: new full-speed USB device number 72 using xhci_hcd
[670927.866892] usb 1-7: New USB device found, idVendor=067b, idProduct=2303, bcdDevice= 4.00

[670980.558787] pl2303 ttyUSB0: error sending break = -32

I am using the pl2303 to convert serial/usb

One last thing to note is that when the test is over and I minicom to the pi I can see that it did indeed login successfully:

Please run the pytest command with -vvv and post the complete output.

Thanks - here is the output when I run with -vvv:

Judging from the line numbers and code snippets from the traceback, you are not testing #975.

Instead of testing the PR, could you check if changing the ShellDriver's prompt in your environment config to '\x1b\[\?2004hpi@\w+:[^ ]+ ' works reliably for you?

This is where HEAD is pointing for that last run:

(venv) fermi-4@fermi4-MS-7A67:~/labgrid$ git log --oneline -n 5
5e038e6 (HEAD -> testing_pr) driver/shelldriver: handle bracketed-paste mode
f30264b (origin/master, origin/HEAD, master) Merge pull request #960 from Bastian-Krause/bst/siglent

25d6663 Merge pull request #972 from jluebbe/openocd-st-link-3
60807bd Merge pull request #965 from Bastian-Krause/bst/uboot-idle-console

I did not recreate first test though after checking out that commit - so that is probably why it looks unchanged.

After updating my local.yaml to:

    ShellDriver:
        prompt: '\x1b\[\?2004hpi@\w+:[^ ]+ '

I get a passing test run with warning (HEAD still pointing at same commit as above):
