Capybara / Rspec-在单击“提交”之前,是否可以测试输入框是否已填满?

问题描述 投票:1回答:1

我正在学习RSpec和Capybara,并尝试测试用户是否可以导航到登录页面(由Devise提供支持)并成功登录。成功登录后,测试没有看到应显示的页面。使用浏览器时,如果不存在输入,它将返回登录页面。我正在使用Rails 5。

login_spec.rb

require 'spec_helper'
require 'rails_helper'
RSpec.feature "Logging in a User" do
    scenario "Logging in user shows special content" do
        visit "/"
        click_link "Sign In"    

        page.should have_content("Password")

        #fill in login information
        page.fill_in 'Email', with: '[email protected]'
        page.fill_in 'Password', with: 'some_password'
        click_on 'Log in'

        page.should have_no_content("Wait for the text which is available in the sign in page but not on next page")
        page.should have_content('User:')
        expect(page.current_path).to eq(root_path)
    end
end

水豚错误消息:

  1) Logging in a User Logging in user shows special content
     Failure/Error: page.should have_content('User:')
       expected to find text "User:" in "Log in\nEmail\nPassword\nRemember me\nSign up Forgot your password?"
     # ./spec/features/login_spec.rb:17:in `block (2 levels) in <top (required)>'

是,您可以检查have_field匹配器是否已填写字段

expect(page).to have_field('Email', with: '[email protected]')

将验证页面上带有标签为'Email'和填充值为'[email protected]'的字段。

这不是当前问题的原因,但是是否有原因混合使用RSpecs shouldexpect语法?您确实应该坚持,最好是“期待新代码-所以

expect(page).to have_content("Password")
expect(page).not_to have_content("Wait for the text which is ...

而不是

page.should have_content("Password")
page.should have_no_content("Wait for the text which is ...

而且-您几乎绝对不应该将普通的RSpec匹配器(eq等)与任何与Capybara相关的东西一起使用,而应该使用Capybara提供的匹配器

expect(page).to have_current_path(root_path)

而不是expect(current_path)...
