Re: [go-nuts] where is GOROOT set?

[Brian Candler]

Your error comes from the spurious import of "treesort" in 
treesort_test.go.  (You are already inside package treesort; there is 
nothing to import)

With this line:

$ go test .
# example.com/blah
treesort_test.go:11:2: package treesort is not in GOROOT 
(/usr/local/go/src/treesort)
FAIL    example.com/blah [setup failed]
FAIL

Without this line: it works, once I've completed the code.

$ cat treesort_test.go

package treesort

import (
        //"fmt"
        "math/rand"
        //"sort"
        "testing"
)

func TestSort(t *testing.T) {
        data := make([]int, 50)
        for i := range data {
                data[i] = rand.Int() % 50
        }
}

$ go test .
ok      example.com/blah    (cached)
