Question

尝试禁用或删除黄瓜测试的本地存储空间。

我尝试了以下内容：

page.driver.execute_script("localStorage.clear()")

但我收到以下错误

 One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).

  SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.

Answer 1

我得到了同样的错误。问题是我试图在不首先访问页面的情况下执行脚本。这引发了上面Justin所解释的错误：

shared_context '@user is logged in' do
  before do
    # visit '/'
    credentials = @user.create_new_auth_token
    token = credentials['access-token']
    page.execute_script "localStorage.setItem('token', '#{token}')"
  end
end

这有效：

shared_context '@user is logged in' do
  before do
    visit '/'
    credentials = @user.create_new_auth_token
    token = credentials['access-token']
    page.execute_script "localStorage.setItem('token', '#{token}')"
  end
end

Answer 2

我的工作是：

  visit '<the_url_needed>'
  page.execute_script('if (localStorage && localStorage.clear) localStorage.clear()')

希望有所帮助。
