Error: NaN is less than min_coverage 95 - Unexpected NaN coverage value

[Archie-Elvie]

Describe the bug
While running the action it reports NaN coverage, while lcov it self reports 100%.

Reading tracefile code-coverage/lcov.info
            |Lines       |Functions  |Branches    
Filename    |Rate     Num|Rate    Num|Rate     Num
==================================================
[/workspaces/project/src/]
bar.cpp     | 100%      4| 100%     2|    -      0
==================================================
      Total:| 100%      4| 100%     2|    -      0

To Reproduce
Steps to reproduce the behaviour:

Use the following lcov.info

lcov.info

TN:
SF:/__w/project/project/src/bar.cpp

Thanks for the issue @Archie-Elvie , sorry for the late reply. Is this still an issue?

[Archie-Elvie]

Yeah I still get NaN whenever I try and use it

[alestiago]

I've been able to reproduce this issue on v2.1.0.

A sample can be found here and a pull request with the action failing here.

@Archie-Elvie by any chance do you have a reference to the exact tool you're using to generate the lcov file and the tool you are using to report the lcov file result?

[renancaraujo]

It seems like this is an invalid lcov file, at least from the parser standpoint. There is no data on found/hit for functions and lines, which we use for calculating code coverage.

Closing as a wontfix since there is not much we can do here in this case with the info we have.
