selenium - Behat 我按 "Button"不工作

Question

我在登录表单中有一个提交按钮，即“登录”。输入字段如下所示

<input name="submit" type="submit" value="Log In">

当我按下按钮“登录”提交登录表单时，出现以下错误

    Exception thrown by (//html/.//input[./@type = 'submit' or ./@type = 'image' or ./@type = 'button'][(((./@id = 'submit' or ./@name = 'submit') or contains(./@value, 'submit')) or contains(./@title, 'submit'))] | .//input[./@type = 'image'][contains(./@alt, 'submit')] | .//button[((((./@id = 'submit' or ./@name = 'submit') or contains(./@value, 'submit')) or contains(normalize-space(string(.)), 'submit')) or contains(./@title, 'submit'))] | .//input[./@type = 'image'][contains(./@alt, 'submit')] | .//*[./@role = 'button'][(((./@id = 'submit' or ./@name = 'submit') or contains(./@value, 'submit')) or contains(./@title, 'submit') or contains(normalize-space(string(.)), 'submit'))])[1]

我的步骤如下

  Given I am on "/"
  And I wait for "Log In"
  And I hover on "Log In"
  And I wait for "Log In"   
  When I fill in "LoginForm_username" with my username
  And I fill in "LoginForm_password" with my password
  And I press "submit"

我已经修改了下面的代码，现在可以正常工作了

$page = $this->getSession()->getPage();
$element = $page->find('css',"#formid input[value=\"Log In\"]");
$element->doubleClick();
