XUnit and MSBuild

Recently I needed to execute xUnit tests with MSBuild, so I've spent some time for creating a MSBuild project running the tests. Luckily xUnit already have MSBuild tasks so I just needed to hook it up.
I wanted to search for all xUnit unit test dlls inside a folder and run the tests there. So I'm searching for xunit.core.dll file to get all the folders eventually containing such dlls and then search all these folders for a pattern - *.Tests.dll. When the tests dlls are found xunit task is run for all of them. So here's the result .proj file:
<?xml version="1.0" encoding="utf-8"?>


    <UsingTask TaskName="GetAssemblies" TaskFactory="CodeTaskFactory" AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll">
            <Path ParameterType="System.String" Required="true" />
            <XUnitFileName ParameterType="System.String" Required="false"/>
            <TestsSearchPattern ParameterType="System.String" Required="false"/>
            <Assemblies ParameterType="System.String[]" Output="true" />
            <Code Type="Fragment" Language="cs">
                    var xUnitFileName = XUnitFileName ?? "xunit.core.dll";
                    var testsSearchPattern = TestsSearchPattern ?? "*.Tests.dll";
                    // get all the directories containing xUnit dlls
                    var directories = System.IO.Directory.GetFiles(Path, xUnitFileName, System.IO.SearchOption.AllDirectories)
                        .Select(file => System.IO.Path.GetDirectoryName(file));

                    var assembliesList = new List<string>();

                    foreach(string directory in directories)
                        // get all test dlls from the given paths
                        assembliesList.AddRange(System.IO.Directory.GetFiles(directory, testsSearchPattern, System.IO.SearchOption.TopDirectoryOnly));

                    Assemblies = assembliesList.ToArray();

    <Target Name="Test">
        <GetAssemblies Path="$(BuildRoot).">
            <Output PropertyName="TestAssemblies" TaskParameter="Assemblies"/>
        <xunit Assemblies="$(TestAssemblies)" />

Git History tool

This is a small tool getting history for a path in a given local git repository and exporting it using RazorTemplates

The tool get all the changes between revisions or to a revision of a local git repository and pass the commits to a Razor template which then outputs the result in a given file. The commits can be filtered by a given pat in the repository. 

UsageGitHistory.App.exe [-gitRepo] [-templateFile] [-outputFile] [-endRevision ] [-gitInstallationFolder ] [-includeMerges] [-pageTitle ] [-pathInRepo ] [-startRevision ] 

To use the tool you can pass the following arguments:

  • gitRepo(or just r) - The local path to the git repository 
  • templateFile(or just t) - The path to the Razor template file that will be used for tansforming the list of commits 
  • outputFile(or just o) - The path to the file where the result content will be saved 
  • startRevision(or r or revision) - This argument is optional and is needed if you want to get the changes in a range or to a revision 
  • endRevision(or just er) - Optional argument that specifies the end revision 
  • includeMerges(or just im) - Whether or not the merge commits to be included in the output 
  • gitInstallationFolder(or just gi) - The path to the git executable if it is not set in the Path environment variable 
  • pathInRepo(or just p) - The relative path inside the local repository where you want to get the changes for 
  • pageTitle(or just pt) - This can be used for presentation purposes only. Can be passed to the command line and then output in the result 
You can find the tool on github here. Example usage(example.bat) and razor(example.razor) files inside the project folder.
