Golang flag provided but not defined

Hi I am using a flag when testing in go:
file_test.go var ip = flag.String("ip", "noip", "test")

I am only using this in one test file. And it works fine when only testing that one test file, but when I run: go test ./... -ip alle of the other test file saying: flag provided but not defined.

Have you seen this?


flag.Parse() is being called before your flag is defined.

You have to make sure that all flag definitions happen before calling flag.Parse(), usually by defining all flags inside init() functions.
