Troubleshooting performance testing

Consult the list of common errors and debugging failed scenarios.

Selector not found

Solution: Update UI selectors and validate in Studio.

Package mismatch

Solution: Upgrade to supported package versions and redeploy.

Robot connection issues

Solution: Check Orchestrator configuration and credentials.

Debugging failed scenarios

Solution: Use application logs, drill into HTTP error details, and analyze infrastructure usage charts to isolate root causes.

Troubleshooting Missing PT Metrics (Port 5671 Blocked)

If Performance Testing charts are empty or metrics are missing, it may be caused by a firewall blocking Port 5671, which is required for communication with Azure Event Hub. The Robot uses this port to send performance metrics to the PT Service. If the port is blocked, metrics cannot be transmitted.

Solution:
  1. Run the following command on the Robot machine using Windows PowerShell.
    Test-NetConnection -ComputerName <http://tmh-prod-tmh-eus-ehn.servicebus.windows.net|tmh-prod-tmh-eus-ehn.servicebus.windows.net> -Port 5671Test-NetConnection -ComputerName <http://tmh-prod-tmh-eus-ehn.servicebus.windows.net|tmh-prod-tmh-eus-ehn.servicebus.windows.net> -Port 5671
  2. Interpret the results.
    • Port is open (Expected). This means the Robot can successfully communicate with Azure Event Hub.
      TcpTestSucceeded : TrueTcpTestSucceeded : True
    • Port is blocked. This indicates that the firewall is blocking outbound communication on Port 5671.
      WARNING: TCP connect to (x.x.x.x : 5671) failedWARNING: TCP connect to (x.x.x.x : 5671) failed
      TcpTestSucceeded : FalseTcpTestSucceeded : False

      Allow the following outbound connection (firewall rule).

      ProtocolPortDestinationTCP5671*.<http://servicebus.windows.net|servicebus.windows.net>ProtocolPortDestinationTCP5671*.<http://servicebus.windows.net|servicebus.windows.net>
