Hi Team, I need to execute an endurance test in Azure Load Testing (ALT) for a duration of 48 hours. However, I’m unable to configure the test duration beyond 24 hours in the current settings.

Could you please help me with the required steps or configuration changes to enable a 48-hour test run?
It is urgent can someone look into it on Priority.

    Hi ,

    Thanks for reaching out to Microsoft Q&A.

    Azure load testing does not support a single continuous test run beyond 24 hrs. That limit is fixed and cannot be overridden through configuration.

    If you must run for 48 hours, the only workable approach is:

    1. Split the test into two 24/hour runs.
    2. Use a pipeline (azure devops or github actions) to trigger the 2nd run automatically when the first finishes.

    Aggregate results across both runs in your observability tool (Log analytics, app insights, grafana, etc.).

    There is no native way to run a single 48 hour ALT test.
