Question

使用硒的Opera浏览器出现问题。要下载浏览器二进制文件，我正在使用webdrivermanager插件（https://github.com/bonigarcia/webdrivermanager）

这是实现不同类型浏览器的枚举：

public enum DriverType implements DriverSetup {

    CHROME {
        public WebDriver getWebDriverObject() {
            WebDriverManager.chromedriver().setup();
            return new ChromeDriver();
        }
    },
    FIREFOX {
        public WebDriver getWebDriverObject() {
            WebDriverManager.firefoxdriver().setup();
            return new FirefoxDriver();
        }
    },
    OPERA {
        public WebDriver getWebDriverObject() {
            WebDriverManager.operadriver().setup();
            return new OperaDriver();
        }
    }
}

有一个getWebDriverObject方法的调用：

public class DriverBase {

    public WebDriver driver;

    public WebDriver initializeBrowser() {
        DriverType driverType = DriverType.CHROME;

        try {
            String browser = System.getProperty("browser").toUpperCase();
            driver = DriverType.valueOf(browser).getWebDriverObject();
        } catch (Exception e) {
            System.out.println("No driver specified/Wrong driver specified, default tests running on Chrome");
            driver = driverType.getWebDriverObject();
        }
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.manage().window().maximize();
        return driver;
    }
}

在运行测试之前，我将系统属性浏览器设置为“ opera”。这是输出。默认情况下，测试在chrome中运行，而Opera浏览器没有打开，因此无法正常工作。我该如何解决？

此错误消息...

......表示尽管您的程序按照system property的配置访问了 OperaDriver ，但由于驱动程序规范中的不匹配 Chrome浏览器 被调用。

您的主要问题是，尽管您仍将system property方法中的initializeBrowser() 浏览器设置为 opera ：

DriverType driverType = DriverType.CHROME;

解决方案

按如下所示更改initializeBrowser()方法：

public WebDriver initializeBrowser() {
    DriverType driverType = DriverType.OPERA;

    try {
        String browser = System.getProperty("browser").toUpperCase();
        driver = DriverType.valueOf(browser).getWebDriverObject();
    } catch (Exception e) {
        System.out.println("No driver specified/Wrong driver specified, default tests running on Chrome");
        driver = driverType.getWebDriverObject();
    }

更新

现在您看到的错误为：

org.openqa.selenium.WebDriverException: unknown error: cannot find Opera binary

要解决此问题，您可以按照讨论selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Opera binary with OperaDriver Selenium and Python

通过webdrivermanager使用Selenium运行Opera浏览器的问题
