Php 功能测试单击并等待不工作

我正在用yii编写带有phpunit selenum测试的web应用程序，这里是我的登录表单测试用例

public function testHasLoginForm()
    {
        $this->open('site/login');
        $this->assertTextPresent('Login');

        $this->assertElementPresent('name=LoginForm[username]');
        $this->assertElementPresent('name=LoginForm[password]');

        $this->assertTextPresent('Remember me next time');  
        $this->assertTextPresent('Reset Password?');

        $this->assertElementPresent('name=Login');

        $this->type('name=LoginForm[username]','pradeep@techanveshan.com');
        $this->type('name=LoginForm[password]','password');

        $this->clickAndWait("//input[@value='Login']"); //this line cause the error

    }

除非我下命令，否则一切都会正常的 $this->clickAndWait（//input[@value='Login']）

这一行给了我类似这样的错误：

Invalid response while accessing the Selenium Server at "http://localhost:4444/s
elenium-server/driver/:" ERROR: Command execution failure. Please search the use
r group at https://groups.google.com/forum/#!forum/selenium-users for error deta
ils from the log window.  The error message is: Value does not implement interfa
ce Event.

有人知道为什么会这样吗

clickAndWait() is not available in RC or webdriver.

相反，您可以使用

$this->click("//input[@value='Login']");
$this->waitforpagetoload("30000");

相反，您可以使用

$this->click("//input[@value='Login']");
$this->waitforpagetoload("30000");

尝试按名称单击：$this->clickAndWait（'//input[name=“LoginForm[username]”）；尝试按名称单击：$this->clickAndWait（'//input[name=“LoginForm[username]”）；
