Hello Gophers!

1. go version go1.4.1 darwin/amd64
2. OS X Yosemite, amd64.
3. Ran go test -cover . in a package with import cycle in the tests.
4. It should fail to compile the tests.
5. It didn't fail and hang instead.

to reproduce

Fetch repository github.com/aybabtme/hangcover and run ./reproduce.sh.

$ ./reproduce.sh
GOROOT=$(go env GOROOT)
go env GOROOT
GIT_DIR="$GOROOT/.git" git rev-parse --verify HEAD
886b02d705ffb1be8b4974ac4c355d480a24e3ec

go version
go version go1.4.1 darwin/amd64
go test -cover github.com/aybabtme/hangcover
^C⏎

description

If a test file has the same package name as the package it tests,
and if that test file imports the package it tests:

// hangcover.go
package hangcover

// hangcover_test.go
package hangcover

import "github.com/aybabtme/hangcover"

Then running go test github.com/aybabtme/hangcover will fail with an import cycle error:

# github.com/aybabtme/hangcover
./hang_test.go:4: import "github.com/aybabtme/hangcover" while compiling that package (import cycle)
FAIL    github.com/aybabtme/hangcover [build failed]

But running go test -cover github.com/aybabtme/hangcover will hang:

go test -cover github.com/aybabtme/hangcover
^C⏎
