I am facing the same issue. I have go binary running in a docker container (built using -cover -covermode=atomic) I am doing API testing by calling HTTP / grpc endpoints to the service (and comparing the response - an independent tool is doing this using curl / grpcurl)
I see that covmeta file is created, but when tests are running, covcounter are not generated. Now, for graceful shutdown, I tried docker compose down - but this is not working. Would someone be able to help? On Wednesday, July 12, 2023 at 5:48:31 PM UTC+5:30 savita juyal wrote: > Thank you so much Brian for helping me identify the problem.
