How to Generate the Test Studio Application Log

Test Studio application logging records all events triggered from the tool while recording tests, executing these or maintaining elements and tests in the project. It is a powerful source of information, which helps to investigate any sort of issues.

The log is a plain text file stored in the Logs sub-folder under the product's installation one C:\Program Files (x86)\Progress\Test Studio. By default logging is disabled and if you need to generate it, you first need to enable it.

The topics in this article guides you through the different options to access the logging:

When to Generate Application Log?

The application log is a set of records, which are useful for analyzing all sort of inconsistent behavior while working on a project in Test Studio. The application log is useful for unexpected occurrences such as:

  • a crash in the product;
  • unexpected termination of a test run, which might prevent generating the execution log;
  • inconsistent behavior while working with the project components (Elements Explorer, Project Explorer, Properties pane, configuring/using the Source Control integration, configuring the Scheduling services, etc.);

The steps below describe the recommended approach for generating the application log so that it contains the details for the encountered error:

  • Clear the log file;
  • Ensure logging is enabled;
  • Reproduce the misbehavior to be investigated;
  • Once the observed inconsistency is present, open the application log from the 'View Log' option;
  • The logging records are opened in a text editor file (usually Notepad);
  • You can revise the logged messages yourself and try to find a solution based on the error message.
  • Or you can contact the Test Studio Support Team and send the zipped log file via a support thread describing the experienced issue.

Operate with Logging in Scheduling Configuration

Test Studio Scheduling setup allows you to connect multiple machines for test execution remotely. When such setup is configured you can find a list of all included machines in the Machine status view accessible from your local computer. From this list you can access the logging options (enable, view, clear, disable) for the Scheduling server machine and for each of the execution machines.

  1. Open the Machine status view and select the Magnifier icon in the Scheduling server section.

Enable Logging through the Registry Editor

Enabling the logging creates a key in the registry with specific value. If you don't have access to any of the above sources, or you use the Telerik Testing Framework, you can enable the logging directly in the Windows Registry Editor.

Start Regedit and browse to the Test Studio folder. The path for default installation is:

  • Computer\HKEY_CURRENT_USER\Software\Wow6432Node\Telerik\Test Studio


Find (or create) the TraceLogEnabled key in this folder. Double click it and change the Value data to 1. The TraceLogPath value is where the log gets stored. Ensure to isnert the file full path with name and file extension like this C:\Temp\TraceLog\log.txt.
