您忘记打电话WebDriver#get以访问某个页面。
WebDriver driver = FirefoxDriver();

List<WebElement> elements = driver.findElements(By.tagName("a"));

In the code provided no website is retrieved. Try accessing a web page and then getting the aelements. Also trying changing from List<WebDriver>to List<WebElement>
在提供的代码中，没有检索到网站。尝试访问网页，然后获取a元素。还尝试从 更改List<WebDriver>为List<WebElement>
WebDriver driver = FirefoxDriver();
driver.get("http://www.google.com");
List<WebElement> elements = driver.findElements(By.tagName("a"));
See this example: http://www.seleniumhq.org/docs/03_webdriver.jsp#introducing-the-selenium-webdriver-api-by-example
请参阅此示例：http: //www.seleniumhq.org/docs/03_webdriver.jsp#introducing-the-selenium-webdriver-api-by-example
The following example works for me:
以下示例对我有用：
public class SeleniumTest {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
// And now use this to visit Google
driver.get("http://www.google.com");
List<WebElement> elements = driver.findElements(By.tagName("a"));
for (WebElement element : elements) {
System.out.println(element.getText());
}
}
}
