Question

After looking around I can t find a simple answer to this problem.

I am trying to create an MSBuild file to allow me to easily use SpecFlow and NUnit within Visual Studio 2010 express.

The file below is not complete this is just a proof of concept and it needs to be made more generic.

<Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

    <PropertyGroup>
        <BuildDependsOn>
            BuildSolution;          
            SpecFlow;
            BuildProject;           
            NUnit;
        </BuildDependsOn>
    </PropertyGroup>

    <PropertyGroup>
        <Solution>C:UsersCraigDocumentsMy DropboxCellsCells.sln</Solution>
        <CSProject>C:UsersCraigDocumentsMy DropboxCellsConfigurationConfiguration.csproj</CSProject>
        <DLL>C:UsersCraigDocumentsMy DropboxCellsConfigurationinDebugConfiguration.dll</DLL>
        <CSFile>C:UsersCraigDocumentsMy DropboxCellsConfigurationSpecFlowFeature1.feature.cs</CSFile>
    </PropertyGroup>

    <Target Name="Build" DependsOnTargets="$(BuildDependsOn)">
        <Message Text="Build Started" Importance="high" />
        <Message Text="Build Ended" Importance="high" />
    </Target>

    <Target Name="BuildSolution">
        <Message Text="BuildSolution Started" Importance="high" />
            <MSBuild Projects="$(Solution)" Properties="Configuration=Debug" />
        <Message Text="BuildSolution Ended" Importance="high" />
    </Target>

    <Target Name="SpecFlow">
        <Message Text="SpecFlow Started" Importance="high" />
            <Exec Command= SpecFlow generateall "$(CSProject)"  />
        <Message Text="SpecFlow Ended" Importance="high" />
    </Target>

    <Target Name="BuildProject">
        <Message Text="BuildProject Started" Importance="high" />
            <MSBuild Projects="$(CSProject)" Properties="Configuration=Debug" />
        <Message Text="BuildProject Ended" Importance="high" />
    </Target>

    <Target Name="NUnit">
        <Message Text="NUnit Started" Importance="high" />
            <Exec Command= NUnit /run "$(DLL)"  />
        <Message Text="NUnit Ended" Importance="high" />
    </Target>
</Project>

The SpecFlow Task looks in the .csproj file and creates a SpecFlowFeature1.feature.cs. I need to include this file when building the .csproj so that NUnit can use it.

I know I could modify (either directly or on a copy) the .csproj file to include the generated file but I d prefer to avoid this.

My question is: Is there a way to use the MSBuild Task to build the project file and tell it to include an additional file to include in the build?

Thank you.

Answer 1

I found no way of doing it without editing the project file.

So I made an MSBuild file to:

Copy the project files
Run the copies through SpecFlow
Add the new .cs files to the copied projects
Compile the projects
Debug Run each of the compiled DLLs through NUnit
Clean up - Delete the copied projects

I ve blogged about how to use it here:

(It s version 1, I d like to improve the script)

Answer 2

I couldn t think of any way to achieve without any modification to the .csproj file.

The approach I d suggest would look like this.

In your .csproj you Import a container target file

...
<Import Project="SpecFlow.target" />
<Import Project="$(MSBuildToolsPath)Microsoft.CSharp.targets" />
...

just above the CSharp.targets.

Specflow.targets would look like this

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <ItemGroup>
        <Compile Include="@(Compile)" />
    </ItemGroup>
</Project>

so it doesn t harm while building the project from VS.

You could then use the Output of your SpecFlow Exec and add it to the SpecFlow.targets file

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <ItemGroup>
        <Compile Include="@(Compile)" />
        <Compile Include="SpecFlowFeature1.feature.cs" />
    </ItemGroup>
</Project>

...

and clean SpecFlow.targets after building your .csproj.
