I have a function in Go that I want to unit test but that function
contains os.Hostname().Hence i thought of mocking os.Hostname.
Example:
func F(){
hostname, _ := os.Hostname()
}
I tried something like this:
var osHostname = os.Hostname
func TestF(t *testing.T) {
expected := "testing"
defer func() { osHostname = os.Hostname }()
osHostname = func()(string, error) { return "testing", nil }
actual := F()
assert.Equal(t,expected,actual)
}
But this doesn't work.Can someone please point me in the right direction?
Thanks,
Nitish
