java - webdriver 是类还是接口(interface)？

Question

来自Selenium docs ，WebDriver 是一个接口(interface)，但在 Eclipse 中，包 org.openqa.selenium 在 Project Explorer 中显示为一个类。此外，如果 WebDriver 是一个接口(interface)，则实现它的 ChromeDriver 或 InternetExplorerDriver 等类应该定义 .get() 或 .getCurrentUrl() 等方法。在哪里可以看到这些方法的方法定义呢？

Answer 1

WebDriver 是一个公共(public)接口(interface)，我不认为 ChromeDriver 或任何其他驱动程序实现了 WebDriver，他们宁愿扩展 RemoteWebDriver 这是一个类。

正如我所说的，驱动程序扩展了 RemoteWebDriver 并且具有这些方法的实际实现..

public void get(String url) {
   execute(DriverCommand.GET, ImmutableMap.of("url", url));
}

Java 源代码:

public interface WebDriver extends SearchContext {
  // Navigation

  /**
   * Load a new web page in the current browser window. This is done using an HTTP GET operation,
   * and the method will block until the load is complete. This will follow redirects issued either
   * by the server or as a meta-redirect from within the returned HTML. Should a meta-redirect
   * "rest" for any duration of time, it is best to wait until this timeout is over, since should
   * the underlying page change whilst your test is executing the results of future calls against
   * this interface will be against the freshly loaded page. Synonym for
   * {@link org.openqa.selenium.WebDriver.Navigation#to(String)}.
   *
   * @param url The URL to load. It is best to use a fully qualified URL
