java - org.openqa.selenium.InvalidArgumentException : Invalid capabilities using DesiredCapabilities

Question

我已将我的 Selenium 框架升级到最新版本。在执行代码期间，我收到以下异常:

异常:

org.openqa.selenium.InvalidArgumentException: 
Invalid capabilities in alwaysMatch: unhandledPromptBehavior is type boolean instead of string

详细信息:

• Selenium :3.7.1；
• IE:3.7.0(32 位驱动程序)；
• java.version: '1.8.0_144'。

较新的版本建议 driver = new InternetExplorerDriver(capabilities); 已弃用。我在函数中单独设置浏览器的功能，并将其作为参数传递给驱动程序。

如何解决这个问题？

代码片段:

desiredCapabilities(browser);

IE Capabilities Setting:- 
capabilities = new DesiredCapabilities().internetExplorer();
capabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_ALERTS, true);
capabilities.setCapability(InternetExplorerDriver.UNEXPECTED_ALERT_BEHAVIOR, true);
capabilities.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
capabilities.setCapability(InternetExplorerDriver.ENABLE_ELEMENT_CACHE_CLEANUP, true);
capabilities.setCapability("nativeEvents", false);
capabilities.setCapability("requireWindowFocus", false);
capabilities.setJavascriptEnabled(true);
capabilities.setCapability("ignoreProtectedModeSettings", true);
System.setProperty("webdriver.ie.driver", ieExe.getAbsolutePath());

然后我调用我的驱动程序:

driver = new InternetExplorerDriver(capabilities);

好吧， Selenium 来自 v3.7 的实现 病房不再接受DesiredCapabilities类型对象作为参数来初始化 Web Browser实例而不是强类型 Options类是首选。所以你必须使用 InternetExplorerOptions 类对象，使用 merge 来自 MutableCapabilities 的论点 并作为参数传递。您的代码块将如下所示:

System.setProperty("webdriver.ie.driver", "C:\\Utility\\BrowserDrivers\\IEDriverServer.exe");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS", true);
capabilities.setCapability("ACCEPT_SSL_CERTS", true);
capabilities.setCapability("SUPPORTS_ALERTS", true);
capabilities.setCapability("UNEXPECTED_ALERT_BEHAVIOR", true);
capabilities.setCapability("IE_ENSURE_CLEAN_SESSION", true);
capabilities.setCapability("ENABLE_ELEMENT_CACHE_CLEANUP", true);
capabilities.setCapability("nativeEvents", false);
capabilities.setCapability("requireWindowFocus", false);
capabilities.setJavascriptEnabled(true);
capabilities.setCapability("ignoreProtectedModeSettings", true);
InternetExplorerOptions opt = new InternetExplorerOptions();
opt.merge(capabilities);
WebDriver driver = new InternetExplorerDriver(opt);
