go selenium较好的库

在go+selenium 上踩了不少坑，推荐下面这个比较完善的库
https://github.com/tebeka/selenium
支持chrome、safari、firefox、IE

另外还有：
https://github.com/sclevine/agouti
https://github.com/sourcegraph/go-selenium

放在一起的例子：

package main

import (
	agwd "github.com/sclevine/agouti"
	tbwd "github.com/tebeka/selenium"
	"log"
	sgwd "sourcegraph.com/sourcegraph/go-selenium"
)

// Helper for sourcegraph/go-selenium
type fatalfer struct{}

func (fatalfer) Fatalf(fmt string, v ...interface{}) {
	panic([]interface{}{fmt, v})
}

var errorhandler fatalfer

// Helper for tebeka/selenium and agouti
func checkError(err error) {
	if err != nil {
		panic(err)
	}
}

func main() {
	defer func() {
		r := recover()

		// Catch the errors from the tebeka/selenium and agouti helpers
		err, is_error := r.(error)
		if is_error {
			log.Fatal(err)
		}

		// Catch the errors from the sourcegraph/go-selenium helper
		arr, is_array := r.([]interface{})
		if is_array {
			fmt := arr[0].(string)
			v := arr[1].([]interface{})
			log.Fatalf(fmt, v...)
		}
	}()

	//sourcegraphExample()
	//tebekaExample()
	//agoutiExample()
}

func sourcegraphExample() {

	// Pro: .T
	// Con: Doesn't report the full error

	var err error
	wdRaw, err := sgwd.NewRemote(sgwd.Capabilities(map[string]interface{}{"browserName": "chrome"}), "http://localhost:4444/wd/hub")
	checkError(err)
	driver := wdRaw.T(errorhandler)
	defer driver.Quit()

	// Make sure the debug panel doesn't overlay the login
	driver.ResizeWindow(driver.CurrentWindowHandle(), sgwd.Size{1200, 500})
