Monitoring coverage in Atlassian Bamboo

The following XSLT will transform OpenCover's XML output to the old NCover 1.x format understood by Atlassian's Bamboo Continuous Integration Server.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="xml" indent="yes" standalone="yes"/>
  <xsl:template match="/CoverageSession/Modules">
    <coverage>
      <xsl:for-each select="Module[not(@skippedDueTo)]">
        <module name="{ModuleName}">
          <xsl:for-each select="Classes/Class">
            <xsl:if test="count(Methods/Method) &gt; 0">
              <class name="{FullName}">
                <xsl:variable name="className" select="FullName" />
                <xsl:for-each select="Methods/Method">
                  <method class="{$className}">
                    <xsl:for-each select="SequencePoints/SequencePoint">
                      <seqpnt visitcount="{@vc}" />
                    </xsl:for-each>
                   </method>
                </xsl:for-each>
              </class>

Example MSBuild target.

    <CoverageFiles Include="$(TestsDir)\*.opencover" />
  </ItemGroup>

  <XslTransformation XmlInputPaths="%(CoverageFiles.Identity)" 
    XslInputPath="$(MSBuildProjectDirectory)\opencover_to_ncover.xslt" 
    OutputPaths="$(TestsDir)\%(CoverageFiles.FileName).ncover.xml" />
