Answer 1

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;

}

Can be called in your code in the following way:

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

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