推荐答案

Satish 的回答是正确的，但通俗地说，ChromeDriver 是专门且仅适用于 Chrome 的驱动程序.WebDriver 是一个更通用的驱动程序，可用于许多不同的浏览器...... IE、Chrome、FF 等.

Satish's answer is correct but in more layman's terms, ChromeDriver is specifically and only a driver for Chrome. WebDriver is a more generic driver that can be used for many different browsers... IE, Chrome, FF, etc.

如果你只关心 Chrome，你可以使用

If you only cared about Chrome, you might create a driver using

ChromeDriver driver = new ChromeDriver();

如果您想创建一个返回指定浏览器驱动程序的函数，您可以执行以下操作.

If you want to create a function that returns a driver for a specified browser, you could do something like the below.

public static WebDriver startDriver(Browsers browserType)
{
    switch (browserType)
    {
        case FIREFOX:
            ...
            return new FirefoxDriver();
        case CHROME:
            ...
            return new ChromeDriver();
        case IE32:
            ...
            return new InternetExplorerDriver();
        case IE64:
            ...
            return new InternetExplorerDriver();
        default:
            throw new InvalidParameterException("Unknown browser type");
    }
}
public enum Browsers
{
    CHROME, FIREFOX, IE32, IE64;
}

...然后称之为...

... and then call it like...

WebDriver driver = startDriver(Browsers.FIREFOX);
driver.get("http://www.google.com");

并且根据您指定的浏览器，该浏览器将被启动并导航到 google.com.

and depending on what browser you specify, that browser will be launched and navigate to google.com.
