Since, at the moment of writing, there is an issue with an incorrect branch coverage being shown in a specific case by Coverlet, I decided to try to collect coverage with Microsoft's coverage collector instead. I have a test.runsettings file:
<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
<DataCollectionRunSettings>
<DataCollectors>
<DataCollector friendlyName="Code Coverage" uri="datacollector://Microsoft/CodeCoverage/2.0" assemblyQualifiedName="Microsoft.VisualStudio.Coverage.DynamicCoverageDataCollector, Microsoft.VisualStudio.TraceCollector, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<Configuration>
<CodeCoverage>
<ModulePaths>
<Include>
<ModulePath>Example.dll</ModulePath>
</Include>
</ModulePaths>
</CodeCoverage>
</Configuration>
</DataCollector>
</DataCollectors>
</DataCollectionRunSettings>
</RunSettings>
that I use like this:
dotnet test --results-directory t --settings:test.runsettings
Then the binary coverage file is converted to an XML report like this:
CodeCoverage.exe analyze /output:c.xml "[...]\example.coverage"
and the final HTML report is generated like this:
reportgenerator -reports:c.xml -targetdir:"report" -reporttypes:Html
The final report—as well as, it seems, the c.xml file—contain only line coverage, and no indications about branch coverage.
How do I get branch coverage as well?
