Testcomplete not executing interactive tests when triggered with TestComplete plugin .

From your logs, this warning stands out:

[WARNING] The node is connected via Java Web Start (JNLP). In this mode, the "Run interactive user session" property of the TestComplete Test step is ignored.

This usually happens because JNLP agents in Jenkins cannot create or unlock a desktop session, which is required for interactive TestComplete or TestExecute tests (like UI automation). So even though your pipeline includes:

useActiveSession: true useTCService: true

These settings are ignored in JNLP mode, and TestExecute can only run in the currently active session — assuming it's already unlocked and ready. That’s likely why your interactive tests aren’t running as expected.

✅ Recommended Fix: Switch to Windows Service Launch

To allow TestComplete to run interactively, the Jenkins agent should be configured to run as a Windows service instead of using JNLP.

Steps:

1. In Jenkins:
   • Go to Manage Jenkins > Manage Nodes and Clouds > [Your Agent] > Configure
   • Change Launch method from:
   • “Launch agent via Java Web Start (JNLP)”
     to:
     “Launch agent via Windows Service”
2. On the agent machine:
   • Install the Jenkins agent as a Windows service (if not already).
   • Run the service as a real user account (not Local System) — ideally the same user that runs TestExecute.
   • Ensure that user is logged in and the desktop is unlocked when the test runs.

🔧 Optional Config Update (Recommended)

Here’s a cleaned-up version of your testcompletetest step with a few adjustments:

testcompletetest(
  actionOnErrors: 'FAIL',                    // Fails the build if test fails
  credentialsId: 'UTAAdmin_User_Pass',
  executorType: 'TE',
  executorVersion: '15.40',                  // Match installed version exactly
  generateMHT: true,
  sessionScreenResolution: '1680x1050',
  suite: "${env.Pjs}",
  useTCService: true,
  useActiveSession: true,
  timeout: '21600',                          // 6 hours
  useTimeout: true
)

💡 Tip:

If you’re not tied to a specific TestExecute version, you can omit executorVersion entirely, and the plugin will automatically select the most recent installed version. This can help avoid mismatches if the machine has been updated.

🧪 Diagnostic Steps (If Test Still Fails or No Results Are Generated)

On the agent machine:

• ✅ Does the test run correctly when executed manually using TestExecute?
• ✅ Does it run in the currently logged-in user’s interactive session?
  • Run the test manually (outside Jenkins) and confirm it interacts with the desktop (e.g., opens windows, clicks UI elements).
  • If it doesn’t, there may be issues with the TestExecute configuration, user permissions, or session access.
• ✅ Are .mht or other result logs being generated at all?
• 🔍 Check the default TestComplete log folder "C:\Users\{your-user}\Documents\TestComplete 15\Log" or any custom results directory you’ve configured.

In Jenkins:

• 📁 Use this step to archive the .mht logs for post-job inspection:

archiveArtifacts artifacts: '**/*.mht', allowEmptyArchive: true

• ⚠️ Ensure that no cleanup steps (like cleanWs()) are deleting test results before they’re read.
• 🧾 Review the Jenkins console log for signs of early termination or issues with launching the interactive session.

Looking at the messages that you have posted - Jenkins cannot create a new user session, like logging into the desktop, because JNLP connects within the currently logged-in user's session. Therefore, any "Run interactive user session" setting in the Jenkins TestComplete plugin is ignored. TestComplete or TestExecute will simply run in the current desktop session.

This is just a warning, not an error, but it means TestComplete will only run properly if the desktop is available and unlocked, since JNLP cannot create sessions.
