CodeCoverage reports lines out of range for the test file

FakeIt 2.0.5
Build Tools: MSBuild, VSTest, CodeCoverage

I tried to use FakeIt to creat a new unit test with a mock. Language standard is set to stdcpp17.

The file with the test using FakeIt has 104 lines (including commented lines). When I analysed CodeCoverage xml output file I fould several blocks referencing to the file. The first block seems to be ok, all start_lines are in the range of my test method.

But there are additional blocks with line numbers out of range for this file, e.g.

    <function id="1809028" name="LongLongSub" type_name="" block_coverage="0.00" line_coverage="0.00" blocks_covered="0" blocks_not_covered="5" lines_covered="0" lines_partially_covered="0" lines_not_covered="8">

    <range source_id="52" covered="no" start_line="8204" start_column="0" end_line="8204" end_column="0" />

    <range source_id="52" covered="no" start_line="8228" start_column="0" end_line="8228" end_column="0" />
  </ranges>
</function>

  <ranges>
    <range source_id="52" covered="no" start_line="105" start_column="0" end_line="105" end_column="0" />
  </ranges>
</function>

    <range source_id="52" covered="no" start_line="105" start_column="0" end_line="105" end_column="0" />
  </ranges>
</function>

These lines out of range caused crashes in the subsequent processing of the xml file in my tool chain.

Why do you run the coverage on your tests files ?

[milbrandt]

I want to import the code coverage from Visual Studio to SonarQube/SonarCloud. And there only the xml format is supported.
see at sonar.cfamily.vscoveragexml.reportsPath: Note that the .coveragexml report format offered by Visual Studio is not supported.

[FranckRJ]

You should exclude your tests from the code coverage, there is not point of analyzing them : https://docs.microsoft.com/en-us/visualstudio/test/customizing-code-coverage-analysis?view=vs-2019#include-or-exclude-assemblies-and-members

The filter of test projects is done on SonarQube side. So it was possible to run the complete CI pipeline without the neeed of a runsettings file.
