"no test files" when all tests require a build tag about gocov HOT 3 CLOSED

Argh. So apparently you can't attach arbitrary files to github bugs. How annoying. Anyways, the reproduction is in http://gerg.ca/covtags.zip . Download that file and then:

unzip covtags.zip
cd covtags
export GOPATH=`pwd`
go install -v github.com/axw/gocov/gocov
go install -v -tags=optional mylib
go test -v -tags=optional mylib

So far I've just demonstrated that the package builds and passes its tests. Yes, there is a copy of gocov in there: it was the easiest way to make a self-contained test case.

And now the bug:

./bin/gocov test -v mylib
instrumenting package "mylib"
failed to instrument package(mylib): no test files

Expected outcome: it should run my tests and print the coverage data in json format. It would be entirely reasonable to require that I run gocov test -tags=optional -v mylib in this case.

Thanks for reporting this. Indeed, you should be able to add -tags to gocov test.

Working on a patch. Looks doable...
