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: process_test.go
    path of file: ./repos/jsii/packages/@jsii/go-runtime/jsii-runtime-go/internal/kernel/process
    
    the code of the file until where you have to start completion: package process

import (
	_ "embed"
	"fmt"
	"io/ioutil"
	"os"
	"os/exec"
	"runtime"
	"strings"
	"testing"
)

//go:embed jsii-mock-runtime.js
var mockRuntimeSource []byte
var mockRuntime string

	file, _ := ioutil.TempFile("", "jsii-mock-runtime.*.js")
	if _, err := file.Write(mockRuntimeSource); err != nil {
		panic(err)
	}
	file.Close()
	mockRuntime = file.Name()

	status := m.Run()

	// Clean up temporary file
	os.Remove(mockRuntime)

	os.Exit(status)
}

// TestVersionCheck ensures the version check logic works correctly. As a side
// benefit, it validates we are correctly launching custom JSII_RUNTIME processes
// as this relies on a mock implementation.
