Golang: tests and working directory

Issue

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?

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)
}
