With New Test Create (NTC), we are introducing the Debug Test feature.

Note: The Debug Test feature is new to the V4 (version 4) update and replaces the now-deprecated V3 sandbox feature.  Debug Tests are only available in V4.  Please check out our guide on the Benefits & Advantages of Blazemeter's New Infrastructure and UI for more details.

Run a Debug Test

To run a this test option, just click the blue "Debug Test" button:

Then, it creates a low-scale test run that you can use to validate your configuration:

Rather than alter your test configuration, this feature makes a logical copy of your test, and runs it at a lower scale. The test will run with 10 threads, and for a maximum of 5 minutes or 100 iterations, whichever occurs first.

Any test initiated by clicking the "Debug Test" button, will be considered as 'free', and will not charge a credit or VUH (Virtual User Hours) for the test run.

Notice: Did you encounter the following error when starting a debug test:

Viewing Detailed Request/Response Data

Detailed request and response information can be found in the 'trace.jtl' file, which is added to the artifacts.zip file for "Debug Test" runs. 

NOTE: These "Debug Test" runs do not appear in test trends, the Reports drop-down menu, or "Show All Reports" lists.  Also, they do not enforce, or display a "Passed/Failed" status. Last, the data for "Debug Test" runs is deleted after 30 days.
