當使用Safari Technology Preview運行safaridriver時出現「錯誤：ConnectFailure（連接被拒絕）」

Question

由於在當前版本的Safari和safaridriver中檢測元素可見性的問題，如here所述，我嘗試使用Safari技術預習。呼叫是在這裏：

return new SafariDriver("/Applications/Safari Technology Preview.app/Contents/MacOS/"); 

這似乎是工作，因爲它推出Safari瀏覽器技術預覽版測試開始時。然而，在啓動之後，什麼也沒有發生，我收到以下：

Error: ConnectFailure (Connection refused) 

完整的堆棧跟蹤是在這裏：

注意：如果使用當前版本的版本我沒有得到這個錯誤的Safari。

我在DOTNET使用Selenium 3.0.1執行代碼。我正在使用Safari Technology Preview v。22，macOS Sierra 10.12.3。在「顯影」菜單中選中「允許遠程自動化」。我手動運行/ Applications/Safari技術Preview.app/Contents/MacOS/safaridriver。

有關如何使這項工作的任何想法？

Answer 1

在Python，這裏是我做過什麼：

driver = webdriver.Safari(port=0, executable_path="/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver") 
driver.get("https://www.google.com") 

您可能還需要查看： https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/safari/SafariOptions.html

在這裏：https://github.com/SeleniumHQ/selenium/issues/3506 其中lmtierney說：

That would depend on the language bindings you're using. You should be able to pass the executable path somewhere and it would be /Applications/Safari Technology Preview/Contents/MacOS/safaridriver. Some language bindings allow a flag to automatically use the tech preview safaridriver.

我希望這是有幫助的。 :)
