Getting "Error: ConnectFailure (Connection refused)" when running safaridriver using Safari Technology Preview
Getting "Error: ConnectFailure (Connection refused)" when running safaridriver using Safari Technology Preview
由于在当前版本的 Safari 和 safaridriver 中检测元素可见性的问题，如前所述 ，我尝试使用 Safari Technology Preview 启动我们的测试。电话来了：
return new SafariDriver("/Applications/Safari Technology Preview.app/Contents/MacOS/");
这似乎可行，因为它会在测试开始时启动 Safari 技术预览。然而，启动后，什么也没有发生，我收到以下信息：
Error: ConnectFailure (Connection refused)

注意：如果我使用当前发行版的 Safari，则不会出现此错误。
我已经使用 Selenium 3.0.1 在 dotnet 中实现了代码。我使用的是 Safari Technology Preview v. 22，macOS Sierra 10.12.3。在“开发”菜单中选中“允许远程自动化”。我有 运行 /Applications/Safari 技术预览。app/Contents/MacOS/safaridriver 一次手动。
关于如何让它工作有什么想法吗？
在 Python 中，这是我所做的：
driver = webdriver.Safari(port=0, executable_path="/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver")
driver.get("https://www.google.com")

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.
希望对您有所帮助。 :)
