But now this broke me again for the opposite reason: The go binary in my $PATH is a script which uses the right go binary for the GOROOT I'm currently testing:

bradfitz@laptop http$ which go
/Users/bradfitz/bin/go
bradfitz@laptop http$ cat $HOME/bin/go
#!/bin/sh

exec $GOROOT/bin/go "$@"

And the error locally:

bradfitz@laptop http$ go test -v -run=TestCmdGoNoHTTPServer
=== RUN   TestCmdGoNoHTTPServer
--- FAIL: TestCmdGoNoHTTPServer (0.08s)
        http_test.go:71: go tool nm: exit status 1: open /Users/bradfitz/bin/go: unrecognized object file
FAIL
exit status 1
