Golang: tests and working directory

go, unit-testing, working-directory

Solution

You may be able to use the Caller to get the path to the current test source file, like this:

package sample

import (
    "testing"
    "runtime"
    "fmt"
)

func TestGetFilename(t *testing.T) {
    _, filename, _, _ := runtime.Caller(0)
    t.Logf("Current test filename: %s", filename)
}

Problem

I'm writing some unit tests for my application in Go. The tests fail however because it cannot find the configuration files. Normally the binary looks for the configuration files in the working directory under the path `conf/*.conf`. I figured that browsing to the directory that has `conf/` and running `go test` in it would solve it, but it still reports that the file system cannot find the path specified. How can I tell `go test` to use a certain directory as the working directory so that the tests may actually be executed?
