Could not find data collector 'XPlat Code Coverage' when targetting .dll #1118

> dotnet add package coverlet.collector dotnet test my.csproj --collect:\"XPlat Code Coverage\" works. great!

dotnet test bin/debug/netcoreapp3.1/test.dll --collect:\"XPlat Code Coverage\"

Data collection : Unable to find a datacollector with friendly name 'XPlat Code Coverage'.
Data collection : Could not find data collector 'XPlat Code Coverage'

What am i missing here? Im writing a tool that integrates with coverage so i would like to support both scenarios.

dotnet --version = 5.0.101

Can you try with

dotnet vstest bin/debug/netcoreapp3.1/test.dll --collect:\"XPlat Code Coverage\"

As explained in guide for published project https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/VSTestIntegration.md

Can you explain why I cant use dotnet test ?

None of the examples here use vstest ?

Like i said, Im writing a tool that is supposed to let users execute any test written by any test framework. My understanding was dotnet test facilitated this.

It's an implementation detail of test platform, we don't load collectors we implement one, you should open an issue and ask here https://github.com/microsoft/vstest/issues
