* Revert "exclude test folder from codecov. (#2227)"
This reverts commit eed91b988f.
* Use a fake target path to avoid tonerdo/coverlet#318
* Manually apply codecov flags through multiple uploads
Eventually codecov.io should support the automatic application of flags
based on directory structure. In the meantime, upload the coverage
report twice and allow the server to filter and apply the desired flags.
* Show production code numbers when coverage is reported
