Using NCover/NCoverExplorer from MsBuild

February 1, 2008

In my previous post I mentioned how easy it is to incorporate code coverage into TeamCity using NCover/NCoverExplorer. I'm using the NCoverExplorer Extras package that can be downloaded here.

On popular demand, here is a sample from my MsBuild file:

<UsingTask 
TaskName="NCoverExplorer.MSBuildTasks.NCover"
AssemblyFile="NCoverExplorer.MSBuildTasks.dll"/>

<UsingTask 
TaskName="NCoverExplorer.MSBuildTasks.NCoverExplorer"
AssemblyFile="NCoverExplorer.MSBuildTasks.dll"/>

<Exec Command="regsvr32 /s 
    $(tools_dir)\NCover\CoverLib.dll"/>

<NCover 
Assemblies="@(CodeCoverage_Assemblies)"
CommandLineArgs="@(UnitTest_Assemblies, ' ')" 
CommandLineExe="$(tools_dir)\NUnit\nunit-console.exe"
CoverageFile="$(CodeCoverageResultsXmlFile)"
LogLevel="Quiet"
ToolPath="$(tools_dir)\NCover\"/>

<NCoverExplorer 
CoverageFiles="$(CodeCoverageResultsXmlFile)"
FailMinimum="false" 
HtmlReportName="CodeCoverage.html" 
OutputDir="$(ProjectPath)" 
ProjectName="$(ApplicationName)" 
ReportType="ModuleClassSummary" 
SatisfactoryCoverage="60" 
ToolPath="$(ToolsDir)\NCoverExplorer\"/>

<Exec Command="regsvr32 /u /s 
    $(toolsdir)\NCover\CoverLib.dll"/>

Still a lot of XML, but it works. The regsvr32 command before and after the NCover/NCoverExplorer task is to make sure that NCover is  working correctly. This because I've put the NCover/NCoverExplorer binaries in my Subversion repository. The CoverLib.dll file must be registered.

If you and your team want to learn more about how to write maintainable unit tests and get the most out of TDD practices, make sure to have look at our trainings and workshops or check out the books section. Feel free to reach out at infonull@nullprincipal-itnull.be.
