Fine code coverage is not visible
I'm using Microsoft Visual Studio Professional 2019 Version 16.11.18 . i have created a simple google test project in c++. in the test explorer 1 test case is getting passed, but fine code coverage summary is showing all as 0

After setting RunMsCodeCoverage to Yes, i'm getting the below error. Please help to solve that error

No, i tried setting the environment variable VSTEST_CONNECTION_TIMEOUT to 6000. Still the coverage is not getting generated
Can you post your generated run settings from directoty \Debug\fine-code-coverage\coverage-tool-output
Perhaps you can check this too https://learn.microsoft.com/en-us/visualstudio/test/troubleshooting-code-coverage?view=vs-2022
Can we use fine code coverage to generate a coverage for C project having cunit test framework?
Attached is the runsettings generated Sample-Test1-fcc-mscodecoverage-generated.txt
Can we use fine code coverage to generate a coverage for C project having cunit test framework?
I believe ms code coverage is C# or C++. Did you mean C++ ?
from https://learn.microsoft.com/en-us/visualstudio/test/writing-unit-tests-for-c-cpp?view=vs-2022 Visual Studio includes these C++ test frameworks with no additional downloads required:
Microsoft Unit Testing Framework for C++ Google Test Boost.Test CTest You can use the installed frameworks, or write your own test adapter for whatever framework you want to use within Visual Studio. A test adapter integrates unit tests with the Test Explorer window. Several third-party adapters are available on the Visual Studio Marketplace. For more information, see Install third-party unit test frameworks.
So cunit would need a test adapter.
Thanks for the information.
Currently i'm using google test framework for which i have attached runsettings earlier.

Hello, is it supporting branch coverage for C++, I tested it with VS2022 and the line coverage works well, but the branch coverage always shows 0.
Given that C++ worked for me ( admittedly on a very simple project ) and for the user above - closing as VSTEST_CONNECTION_TIMEOUT is a vstest issue and not FCC related.
