Debugging in Selenium Using Telemetry Logs

TestMu AI Automation allows you to perform parallel test execution through a standalone mode that connects to the Selenium server, where each test can have multiple requests.

To trace each request, you can use Selenium 4 and OpenTelemetry integration to achieve greater visibility into request tracing and event logs. Tracing enables the monitoring of a request's life cycle and stores essential information about the request's critical operations. You can use this information to identify issues and optimize the performance of your web applications.

Managing several requests, tracing logs, and troubleshooting request failures in a distributed environment can be challenging. In such instances, you can integrate Telemetry logs with Jaeger - a distributed tracing system - to quickly visualize and query traces.

Supported Operating Systems

Telemetry logs are available on these operating systems.

Windows 11
Windows 10
macOS Ventura
macOS Catalina
macOS Mojave

Enabling Telemetry Logs

Pass the seTelemetryLogs and selenium_version capabilities to activate telemetry logging.

Note

TestMu AI Automation supports Telemetry logs on Selenium versions above 4.2.0.

By default, Telemetry logs are disabled for Selenium automation on TestMu AI. To enable them in your test sessions:

Pass the seTelemetryLogs capability in your test scripts and set it to true.

caps.setCapability("seTelemetryLogs", true);

Pass the selenium_version capability in your test scripts and set it to 4.2.0.

caps.setCapability("selenium_version", "4.2.0");

Visualizing Telemetry Logs Using Jaeger

Integrate Jaeger to visualize request traces from your test sessions.

Jaeger is an open-source, end-to-end distributed tracing system to monitor and troubleshoot distributed systems. Using Jaeger, you can visualize the request traces of your tests run on TestMu AI.

Here are the steps to integrate Jaeger with your test suites:

Download Jaeger from its official website.
Extract the compressed (.tar.gz or .zip) Jaeger file to the directory where your test script resides. You will now have several Jaeger files like jaeger-query, jaeger-collector, etc., in your test script directory.
Download Telemetry logs of your test session from the Telemetry Logs tab of your TestMu AI Automation Dashboard.
