Question

我正在尝试在java绑定下使用带有Selenium的chrome驱动程序。我按照以下说明操作：ChromeDriver Instructions

所以我运行ChromeDriver.exe，把它放在我的代码WebDriver driver = new RemoteWebDriver("http://localhost:9515", DesiredCapabilities.chrome());中，我收到此错误：

Error:(33, 28) java: no suitable constructor found for RemoteWebDriver(java.lang.String,org.openqa.selenium.remote.DesiredCapabilities)
    constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(org.openqa.selenium.remote.CommandExecutor,org.openqa.selenium.Capabilities) is not applicable
      (argument mismatch; java.lang.String cannot be converted to org.openqa.selenium.remote.CommandExecutor)
    constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(java.net.URL,org.openqa.selenium.Capabilities) is not applicable
      (argument mismatch; java.lang.String cannot be converted to java.net.URL)

如何让Chrome驱动程序工作？

编辑：使用其他方法：

System.setProperty("webdriver.chrome.driver", "PATH\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

我收到这些错误：

Answer 1

我在尝试代码时遇到了编译错误The constructor RemoteWebDriver(String, DesiredCapabilities) is undefined

对于Java，你可以试试这样的东西，

  System.setProperty("webdriver.chrome.driver","Drive:"+File.separator+"chromedriver.exe");
  driver = new ChromeDriver();
  driver.get(url);

Answer 2

我已经安装了chromedriver throw mac terminal，然后将此代码添加到java类中；它对我有用。

WebDriver driver;
@Test
public void test() throws MalformedURLException {
    WebDriver driver = new RemoteWebDriver(new 
    java.net.URL("http://localhost:9515"), 
    DesiredCapabilities.chrome());
    driver.get("https://www.facebook.com");
    driver.findElement(By.name("email")).sendKeys("hello world");
}

使用Selenium的Chrome驱动程序：＆＃34;没有为RemoteWebDriver找到合适的构造函数＆＃34;
