Hi, thanks for reporting this.

However, I'm unable to reproduce. gopherjs test works as expected for that input:

$ go test
PASS
ok      github.com/shurcooL/play/31 0.018s
$ gopherjs test
gopherjs: Source maps disabled. Use Node.js 4.x with source-map-support module for nice stack traces.
PASS
ok      _/Users/Dmitri/Go/src/github.com/shurcooL/play/310.504s
$ gopherjs test -v
gopherjs: Source maps disabled. Use Node.js 4.x with source-map-support module for nice stack traces.
=== RUN   TestNil
--- PASS: TestNil (0.00s)
PASS
ok      _/Users/Dmitri/Go/src/github.com/shurcooL/play/310.503s
$ ls
gotest.go   gotest_test.go
$ cat gotest.go 
package jstest
$ cat gotest_test.go 
package jstest

import "testing"

func TestNil(t *testing.T) {

}

Using:

go version go1.5.3 darwin/amd64
GopherJS version 0faf2ef97c0ada75462340a914f01fec80521216

Yes I can't reproduce it in a docker container. I'll see if there's something wrong with the setup of my Mac.

OK, this is what I've done:

Rebooted Mac
Deleted $GOPATH/src, $GOPATH/bin, $GOPATH/pkg
Upgraded Go to 1.5.3
Downgraded Node to 4.3.0
go get github.com/gopherjs/gopherjs
go get github.com/davelondon/jstest

Still has the same error. Can you think of anything else to try?

I'll close this issue and continue trying to resolve this myself. I'll post again here when I find the solution.

I'm seeing this as well using 00f306e, and node 6.6.0

nullstyle@8d4d6d0 illustrates a hackish workaround I did to resolve the issue for me. I don't yet know enough about the internals of gopherjs to find the correct way to solve the underlying os.Exit() error.
