使用Capybara + Rails3找不到要点击的元素

Question

背景:我正在使用Capybara和Rspec来测试Rails 3应用程序. 使用的驱动程序:Selenium

问题:我无法找到"登录"按钮,以便在我的测试中点击.

HTML代码:

<form accept-charset="UTF-8" action="/" class="filter_form" id="login" method="post">
        <fieldset>
          <div class="modal-body">
            <div class="clearfix login-fields">
              <label for="user_email">Email</label>
              <div class="input login-inputs">
                <input class="input-text" id="user_email" name="user[email]" placeholder="email" size="30" type="email" value="">
              </div>
            </div>
            <div class="clearfix login-fields">
              <label for="user_password">Password</label>
              <div class="input login-inputs">
                <input class="input-text" id="user_password" name="user[password]" placeholder="password" size="30" type="password">
              </div>
            </div>
          </div>
          <div class="modal-footer">
            <input class="btn btn-primary login_btn" id="btn_login" name="commit" type="submit" value="Sign in">
            <a href="/lms/forgot_password" class="btn">Forgot password...</a>
            <a href="#" class="btn close cancel" data-dismiss="modal">Cancel</a>
          </div>
        </fieldset>
</form>

测试失败

it "should login correctly if the right credentials are given", :js => true do

    Capybara.default_wait_time = 5
    Capybara.reset_sessions!
    visit '/'
    click_link('login_link') #this will bring a modal window with the code posted above using js
    within("#login") do
      fill_in 'user_email', :with => "my-email@example.com"
      fill_in 'user_password', :with => "mypwd"
    end

    response.should have_selector('input#btn_login') #This passes
    click_on("input#btn_login") #Here it fails, saying it can't find an element with that selector
    response.should have_selector(:xpath, '//div[@class="alert-message block-message info"]')
  end

我的测试文件在里面spec/requests.

有任何想法吗？谢谢!

Answer 1

请试试这个:

page.find("#btn_login").click

Answer 2

这:https://stackoverflow.com/a/11348065/1504796

是正确的答案.

click_on不采用CSS选择器,而是采用链接的文本或id.你想要的click_on("btn_login").没有哈希标志或任何东西.

Answer 3

尝试

find('#id',:visible => true).click

Answer 4

尝试将“gem 'launchy'”添加到 Gemfile 中，并将“save_and_open_page”行放在步骤文件中失败行之前。
