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: plugin_executor_test.go
    path of file: ./repos/botkube/pkg/execute
    
    the code of the file until where you have to start completion: package execute

import (
	"testing"

	"github.com/stretchr/testify/assert"
)

func TestPluginExecutor_GetCommandPrefix(
    
func TestPluginExecutor_GetCommandPrefix(t *testing.T) {
	testCases := []struct {
		Name     string
		In       []string
		Expected string
	}{
		{
			Name:     "Single command",
			In:       []string{"kubectl"},
			Expected: "kubectl",
		},
		{
			Name:     "Single verb",
			In:       []string{"kubectl", "get"},
			Expected: "kubectl get",
		},
		{
			Name:     "Multiple args",
			In:       []string{"kubectl", "get", "pods", "-n", "default"},
			Expected: "kubectl get",
		},
		{
			Name:     "Multi-word verb",
			In:       []string{"doctor", "can I ask a question"},
			Expected: "doctor {multi-word arg}",
		},
	}

	for _, tc := range testCases {
		t.Run(tc.Name, func(t *testing.T) {
			p := &PluginExecutor{}

			// when
			out := p.GetCommandPrefix(tc.In)

			// then
			assert.Equal(t, tc.Expected, out)
		})
	}
