Línea de trabajo

Comienza con com.appland.appmap.process.hooks.test.TestNG.testng y la ruta de Recorder.start mostrada en el stack trace; después, inspecciona RecordingSupport.startRecording y TestSupport.startRecording. Reproduce el fallo con TestNG parallel="methods" o parallel="tests" y determina si las sesiones pueden aislarse por hilo o si es necesario deshabilitar el paralelismo. Se considera terminado cuando la ejecución en paralelo ya no provoca ActiveSessionException y las grabaciones siguen completándose.

Descripción

A user running TestNG tests with the appmap-java agent is encountering an ActiveSessionException, which causes the recording to fail. We suspect this is due to TestNG's parallel execution feature, which the AppMap agent's Recorder may not currently support.

When multiple tests run concurrently, each test thread appears to trigger the AppMap TestNG hook (com.appland.appmap.process.hooks.test.TestNG.testng) and attempts to call startRecording. The first test succeeds, but subsequent concurrent tests fail when the Recorder detects that a session is already active, throwing the exception.

Error Log & Stack Trace

The key error message from the user's log is:

Requested Action
  1. Investigate: Please confirm if appmap-java's TestNG support is compatible with parallel test execution (e.g., parallel="methods" or parallel="tests" in the testng.xml suite).
  2. Remediate:
    • Ideally: If possible, update the agent to properly support parallel TestNG execution, perhaps by managing recording sessions on a per-thread basis.
    • Alternatively: If parallel support is not feasible or as an interim solution, please add logic to detect when TestNG parallelism is enabled and automatically disable it (force serial execution) when the AppMap agent is attached. This would prevent the crash and allow users to generate AppMaps, albeit with a slower test run.
