what is a .trx file?

A Visual Studio test results file is created by a software from Microsoft that can be used to create Microsoft Windows applications, and this software is the Visual Studio program, also developed by Microsoft. A Visual Studio test results file is integrated with encoding specifications proprietary to Microsoft for the TRX file format, also proprietary to Microsoft. Affixed with the .trx extension, the content of a Visual Studio test results file contains results associated to particular tests done by a user in the Visual Studio software. This is because the Visual Studio program is implemented with a set of features that can be used to simulate the functionalities coded into a Microsoft Windows application development project to pinpoint certain issues and problems that the Visual Studio software may encounter during the simulation of those application-specific functionalities. This also means these Visual Studio test results files are used for debugging certain problems in a Microsoft Windows application project created with the Visual Studio program, as well as for improving those functionalities. The data stored in these Visual Studio test results files are also used by the Visual Studio application to display in the GUI (Graphical User Interface) of the program the results of certain tests implemented by the user for a Visual Studio application development project.

applications that open a .trx file

Microsoft Visual Studio

Microsoft Visual Studio

Microsoft Visual Studio is an integrated development environment (IDE) produced by Microsoft. It has a code editor that supports syntax highlighting and code completion using IntelliSense for not only variables, functions and methods but also language constructs like loops and queries; includes a debugger that works both as a source-level debugger and as a machine-level debugger; includes a host of visual designers to aid in the development of applications and other tools. Visual Studio permits developers to write extensions for Visual Studio to expand its capabilities. These extensions are linked to Visual Studio and extend its functionality. Extensions come in the form of macros, add-ins, and packages. Macros represent repeatable tasks and actions that developers can write programmatically for saving, replaying, and distributing; add-ins gives access to the Visual Studio object model and can interact with the IDE tools; and packages can create designers and other tools, as well as integrate other programming languages.
Microsoft MSTest

Microsoft MSTest

MSTest is a command line function that executes unit tests created in Visual Studio 2005, Visual Studio 2008 or Visual Studio 2010 and was developed by Microsoft; also called the Visual Studio Test Result. It is integrated with the TRX file format, and contains results associated to the test done by the user.MSTest.exe is the command used to run the test. This command has a number of options the user can use to modify the test run and user can utilize many of these options in conjunction with one another. User can specify these options in any order on the MSTest.exe command line. These Visual Studio test results files are utilized for debugging some problems in a Microsoft Windows application project created with the Visual Studio program, as well as for improving those functionalities. The data saved in these Visual Studio test results files are also used by the Visual Studio application to be shown in the GUI (Graphical User Interface) of the program the results of certain tests implemented by the user for a Visual Studio application development project.

a word of warning

Be careful not to rename the extension on .trx files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .trx. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
