在应用程序中，我想检索像

In the application i would like to retrieve the values like

Properties prop=new Properties();
prop.load("above properties file path")

driver.findelement（prop.getProperty（username）） //在eclipse中，它抱怨说WebDriver类型中的方法findElement（By）不适用于参数（String）

推荐答案

您可以创建一个解析器方法，它将返回所需的定位器对象，如下所示：

You can create one parser method which will return desired locator object something like below:

public static By locatorParser(String locator) {

By loc = By.id(locator);

if (locator.contains("id"))
    loc = By.id(locator.substring(locator.indexOf("\"") + 1,
        locator.length() - 2));

else if (locator.contains("name"))
    loc = By.name(locator.substring(locator.indexOf("\"") + 1,
        locator.length() - 2));

if (locator.contains("xpath"))
    loc = By.xpath(locator.substring(locator.indexOf("\"") + 1,
        locator.length() - 2));

return loc;

}

可以通过以下方式在代码中调用：

Can be called in your code in the following way:

driver.findElement(locatorParser(prop.getProperty("username")));

为id，name，xpath添加了逻辑。您可以修改相同的方法来添加所有可用的定位器。希望这有帮助！

Added logic for id, name, xpath. You can modify the same method to add all the available locators. Hope this helps!
