File Type 1Visual Studio Test Results File
What is a TRX file?
Test results file created by Visual Studio, a Microsoft application used to develop Windows software; contains test results stored in an XML format; used to display test results in Visual Studio as well as save historical test case results.
TRX files may also be created using Microsoft MSTest, a command-line utility that runs unit tests created in Visual Studio 2005 and later. The program executable file MSTest.exe has various command-line options that can be used to customize the output of tests.
NOTE: Test results remain in memory in Visual Studio until they are explicitly written to disk into a TRX file. They can be saved by using the "Export Test Run Results" option in Visual Studio.
