There is only one file type that uses the .TESTRUNCONFIG extension:
Visual Studio Test Run Configuration File
Test settings file used by Microsoft Visual Studio 2008 and earlier; contains configuration information for running a suite of tests; used for defining the test parameters when running collections of test cases, such as unit tests.
NOTE: Microsoft replaced the TESTRUNCONFIG file type with .TESTSETTINGS files in Visual Studio 2010.
