Ignore coverage for a file but need the code to be available to use

Hi Team,

We have a file say ExportedFunctions.go in PkgA which is kept to export a few functions from PkgA for coverage purpose…for our test framework in PkgB. Now if I include the build tag in ExportedFunctions.go to exclude it from the build, the functions won’t be available for use as the file will be ignored while the build process.
If I don’t use the build tag, the file will be shown in the coverage report which is not required.

Now how can I ignore the file from the coverage report and still be able to call functions from ExportedFunctions.go file?

Kindly suggest. Any help would be much appreciated.
