由于在当前版本的 Safari 和 safaridriver 中检测元素可见性的问题，如此处所述，我尝试使用 Safari Technology Preview 启动我们的测试。电话在这里：

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

这似乎有效，因为它会在测试开始时启动 Safari Technology Preview。但是，在它启动后，什么也没有发生，我收到以下信息：

Error: ConnectFailure (Connection refused)

完整的堆栈跟踪在这里：

注意：如果我使用 Safari 的当前发行版本，我不会收到此错误。

我已经使用 Selenium 3.0.1 在 dotnet 中实现了代码。我正在使用 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”。我已经手动运行过 /Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver 一次。

关于如何使它工作的任何想法？

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")

您可能还想看看： https ://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/safari/SafariOptions.html

在这里：https : //github.com/SeleniumHQ/selenium/issues/3506 lmtierney 说：

这将取决于您使用的语言绑定。您应该能够在某处传递可执行路径，它将是 /Applications/Safari Technology Preview/Contents/MacOS/safaridriver。某些语言绑定允许标志自动使用技术预览版 safaridriver。

我希望这是有帮助的。:)
