| <p>Using <a class="reference external" href="http://cobertura.github.io/cobertura/">Cobertura</a> as the coverage generation within your multi-module |
| Java project can generate a series of XML files.</p> |
| <p>The Cobertura Coverage parser expects to read the coverage data from a |
| single XML file which contains the coverage data for all modules. |
| Cobertura has a program with the ability to merge given <code class="docutils literal"><span class="pre">cobertura.ser</span></code> files |
| and then another program to generate a combined XML file from the previous |
| merged file. For command line testing, this can be done by hand prior to |
| CTest looking for the coverage files. For script builds, |
| set the <code class="docutils literal"><span class="pre">CTEST_COVERAGE_COMMAND</span></code> variable to point to a file which will |
| perform these same steps, such as a <code class="docutils literal"><span class="pre">.sh</span></code> or <code class="docutils literal"><span class="pre">.bat</span></code> file.</p> |
| <div class="highlight-cmake"><div class="highlight"><pre><span></span><span class="nb">set</span><span class="p">(</span><span class="s">CTEST_COVERAGE_COMMAND</span> <span class="s">.../run-coverage-and-consolidate.sh</span><span class="p">)</span> |

| <p>where the <code class="docutils literal"><span class="pre">run-coverage-and-consolidate.sh</span></code> script is perhaps created by |
| the <span class="target" id="index-0-command:configure_file"></span><a class="reference internal" href="../command/configure_file.html#command:configure_file" title="configure_file"><code class="xref cmake cmake-command docutils literal"><span class="pre">configure_file()</span></code></a> command and might contain the following code:</p> |
| <div class="highlight-bash"><div class="highlight"><pre><span></span><span class="ch">#!/usr/bin/env bash</span> |
| <span class="nv">CoberturaFiles</span><span class="o">=</span><span class="s2">"</span><span class="k">$(</span>find <span class="s2">"/path/to/source"</span> -name <span class="s2">"cobertura.ser"</span><span class="k">)</span><span class="s2">"</span> |

| --format xml <span class="nv">$SourceDirs</span> |
| </pre></div> |
| </div> |
| <p>The script uses <code class="docutils literal"><span class="pre">find</span></code> to capture the paths to all of the <code class="docutils literal"><span class="pre">cobertura.ser</span></code> |
| files found below the project’s source directory. It keeps the list of files |
| and supplies it as an argument to the <code class="docutils literal"><span class="pre">cobertura-merge</span></code> program. The |
| <code class="docutils literal"><span class="pre">--datafile</span></code> argument signifies where the result of the merge will be kept.</p> |
| <p>The combined <code class="docutils literal"><span class="pre">coberturamerge.ser</span></code> file is then used to generate the XML report |
| using the <code class="docutils literal"><span class="pre">cobertura-report</span></code> program. The call to the cobertura-report |
| program requires some named arguments.</p> |
| <dl class="docutils"> |
| <dt><code class="docutils literal"><span class="pre">--datafila</span></code></dt> |
| <dd>path to the merged <code class="docutils literal"><span class="pre">.ser</span></code> file</dd> |
| <dt><code class="docutils literal"><span class="pre">--destination</span></code></dt> |
| <dd>path to put the output files(s)</dd> |
| <dt><code class="docutils literal"><span class="pre">--format</span></code></dt> |
| <dd>file format to write output in: xml or html</dd> |
| </dl> |
| <p>The rest of the supplied arguments consist of the full paths to the |
| <code class="docutils literal"><span class="pre">/src/main/java</span></code> directories of each module within the source tree. These |
| directories are needed and should not be forgotten.</p> |
