The .trx file format refers to files that represent test results using Microsoft Visual Studio. Programmers use Microsoft Visual Studio to create applications that will run on Microsoft Windows operating system, Windows Mobile, .NET Framework, and Silverlight. They also use the IDE software in developing websites and Web programs.
Before setting a program or an application for the end-user utilization, programmers and designers are required to run multiple tests to identify any issues that have something to do with the viability and feasibility of the programs and applications they created. They consistently test the instructions and features of the newly- made programs before opening it for system wide use. The test results generated in the examinations and quality assessment are saved in Microsoft Visual Studio, tagged with TRX file extension.
The .trx file is a container file type, but its contents after prompting/opening are usually in .xml format. TRX files can also be opened using MS MSTest.
