You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: k8s_test.go
    path of file: ./repos/linkerd2/pkg/k8s
    
    the code of the file until where you have to start completion: package k8s

import (
	"testing"
)

func TestGetConfig(t *testing.T) {
	t.Run("Gets host correctly form existing file", func(t *testing.T) {
		config, err := Ge
    
func TestGetConfig(t *testing.T) {
	t.Run("Gets host correctly form existing file", func(t *testing.T) {
		config, err := GetConfig("testdata/config.test", "")
		if err != nil {
			t.Fatalf("Unexpected error: %v", err)
		}

		expectedHost := "https://55.197.171.239"
		if config.Host != expectedHost {
			t.Fatalf("Expected host to be [%s] got [%s]", expectedHost, config.Host)
		}
	})

	t.Run("Returns error if configuration cannot be found", func(t *testing.T) {
		_, err := GetConfig("/this/doest./not/exist.config", "")
		if err == nil {
			t.Fatalf("Expecting error when config file does not exist, got nothing")
		}
	})
}
