@singhsarab @ShreyasRmsft Any one working on this issue? Can I try?

[singhsarab]

@krishnaanaril Sure, feel free to give it a shot.

@CSmith1111 While going through the source code I found that it is possible to provide filename by adding <CoverageFileName>YourName.coverage</CoverageFileName>in the *.runsettings file.

what if a runsettings file isn't used, is it possible to supply this at the command line? I mean, is it as simple as /p:CoverageFileName=output.coverage? I tried something just as a guess at the prompt and it didn't work as I am supposing here.

All properties from *.runsettings can be specified through command line with [-- <RunSettings arguments>]

Examples:
vstest.console.exe *.dll /EnableCodeCoverage -- DataCollectionRunSettings.DataCollectors.DataCollector.Configuration.CoverageFileName="my.coverage"

For .NET Core:
dotnet test --collect:"Code Coverage" -- DataCollectionRunSettings.DataCollectors.DataCollector.Configuration.CoverageFileName="my.coverage"
