Selenium 驱动程序：-Dwebdriver.driver="iexplorer" 调用 safari

Question

当我尝试运行我的 Serenity 测试自动化时，我调用了以下 maven 命令：

mvn clean verify -Dentry_point="**/*SmokeTestSuite.java" -Dwebdriver.driver="iexplorer" -Dwebdriver.ie.driver="<my path>\IEDriverServer.exe"

我提供了 iexplorer 作为驱动程序和 IEDriverServer.exe 的路径。我的 Internet Explorer 版本是 11.x。当我运行安装 ie 驱动程序时，它会出错，我需要将路径添加到 safari.exe。

以下是错误堆栈跟踪：

此错误消息...

ERROR net.thucydides.core.webdriver.WebDriverFacade - FAILED TO CREATE NEW WEBDRIVER_DRIVER INSTANCE class org.openqa.selenium.ie.InternetExplorerDriver: Could not instantiate class org.openqa.selenium.ie.InternetExplorerDriver
net.thucydides.core.webdriver.UnsupportedDriverException: Could not instantiate class org.openqa.selenium.ie.InternetExplorerDriver

...意味着该程序无法 create/spawn 所需的新 InternetExplorerDriver 实例。

这个错误的主要原因是容易出错的maven命令你用来执行Serenity Test Automation Suite 如下：

mvn clean verify -Dentry_point="**/*SmokeTestSuite.java" -Dwebdriver.driver="iexplorer" -Dwebdriver.ie.driver="<my path>\IEDriverServer.exe"

最常用的 WebDriver 变体是：

-Dwebdriver.gecko.driver - 对于 geckodriver.exe
-Dwebdriver.chrome.driver - 对于 chromedriver.exe
-Dwebdriver.ie.driver - 对于 IEDriverServer.exe

但是因为您使用了不正确的参数作为-Dwebdriver.driver以及不正确的值因为 iexplorer Serenity 测试自动化框架 尝试访问 [=82 的默认配置=].

解决方案

你需要删除容易出错的论点-Dwebdriver.driver="iexplorer"，你就会成功。

Answer 2

webdriver.driver 是设置驱动程序的正确 Serenity 属性。我不确定 DebajanB 的 "error-prone" 是什么意思 - 通常，它可以工作或不工作，如果不工作，则是配置问题。要检查驱动程序属性在 Maven 中是否配置正确（您可能需要将它作为系统属性在 surefire 或 failsafe 插件中传递到您的测试中），看看它是否适用于 firefox。

对 webdriver.gecko.driver 等的引用告诉 Serenity 在哪里可以找到特定驱动程序的二进制文件，但它们并没有告诉 Serenity 使用哪个驱动程序。您可以配置多个驱动程序二进制文件，然后选择使用其中一个 webdriver.driver.

Safari 不是 Serenity 的默认驱动程序，Firefox 是，所以对 Safari 的引用很好奇。这可能是来自旧版本的 defect/misleading 错误消息 - 您使用的是最新版本的 Serenity 吗？
