MsTestTrxLogger
Logger implementation for vstest.console.exe that replicates the TRX format of mstest.exe.
Background
The tool for running MsTest unit tests from the command line used to be mstest.exe.
Later that was replaced by vstest.console.exe, and mstest.exe is now considered deprecated.
The output format of mstest.exe was an XML format called TRX. On the other hand, vstest.console.exe supports multiple loggers, of which one is called "trx", which is supposed to produce the same format as mstest.exe did.
However, there are a couple of differences between the old mstest.exe output, and the vstest.console.exe trx logger output.
These differences can cause some problems, one that I encountered is that SpecFlow cannot generate its HTML report properly any more (details here).
The logger implemented in this repository replicates the format of the old TRX produced by mstest.exe.
(Some more information on the background can be found in this blog post.)
Usage
In order to use the logger, you need to copy its binaries to the Extensions folder depending on your Visual Studio version.
- Before VS2017 the folder is
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\Extensions(where you have to modify the 12.0 version number to the version of thevstest.console.exeyou're using (12.0 is for Visual Studio 2013)); - And starting from VS2017 it should be
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\Extensions\TestPlatform\Extensions.
Then you have to specify the logger to use when executing the tool with the Logger parameter.
vstest.console.exe ... /Logger:MsTestTrxLogger
Optional parameter for MsTestTrxLogger: LogFileName, for if you want to specify the name and path of the output .trx file.
vstest.console.exe ... /Logger:MsTestTrxLogger;LogFileName=<NameOfTestResultsFile.trx>
Getting the binaries
You can get the binaries either by cloning this repo and building the project, or by downloading them from the Releases page.
