How to merge two or more dotnet test code coverage files

Question

I have a .Net solution with two dotnet core class libraries and its associated unit test projects in it.

When I run dotnet test **\\*.Tests.csproj --collect "Code Coverage" command then it generates separate .coveragexml files for each unit test project.

My requirement is to merge all the .coveragexml files into one single file and use that to get the total coverage matrix for a whole solution.

Is there any tool or script to achieve this?

Note:

• I am not using Coverlet.
• I am using built-in vstest.console.exe to run tests and generate .coveragexml file.
• I am using Customize code coverage analysis

如果不需要合并的结果仍然是 .coveragexml 格式，您可以使用 ReportGenerator ( https://github.com/danielpalme/ReportGenerator ) 作为合并工具。
