如何一次运行capybara命令，然后运行一些测试 [英] how to run capybara commands once, then run some tests

问题描述

我有给定的测试代码：

describe 'A new user', js: true do
  before do
    @new_user = Fabricate.build(:user)
  end

  it 'should sign up' do
    #login code
    visit '/'
    click_link 'Login'
    fill_in 'user[email]', :with => @new_user.email
    fill_in 'user[password]', :with => @new_user.password
    click_button 'Login now'
    #login code end

    page.should have_content("Hello #{@new_user.first_name}!")
    current_path.should == dashboard_path
  end

  it 'should receive a confirmation mail' do
    #same login code again
    visit '/'
    click_link 'Login'
    fill_in 'user[email]', :with => @new_user.email
    fill_in 'user[password]', :with => @new_user.password
    click_button 'Login now'

    mail = ActionMailer::Base.deliveries.last
    assert_equal @new_user.email, mail['to'].to_s
  end
end

现在我想添加更多测试。
为避免代码加倍，如何在所有测试之前运行一次capybara登录代码？
一种解决方案是将登录代码放在before方法中。另一个方法是创建一个方法do_login，将代码放入其中并运行每个测试，如下所示：

Now I want to add more tests. To avoid code doubling, how can I run the capybara login code once before all tests? One solution would be to put the login code in the before method. Another would be to create a method do_login, put the code in it and run every test like this:

it 'should do something after login' do
  do_login
  #test code here
end

但是对于这两种解决方案，代码都是针对每个测试运行的，这不是我想要的。将登录代码放在 before（：all）上也不起作用。

But for both solutions, the code is run for every test and thats not what I want. Putting the login code in a before(:all) doesn't work, too.

如何运行一些水豚代码一次，然后在此之后进行所有测试？

How can I run some capybara code once and then do all the tests after this?

推荐答案

您不能一次运行水豚代码然后全部运行测试。您总是从头开始。您提出的使用before（：each）或辅助方法的解决方案是唯一的可能。 （可以在（：all）之前运行一些ruby，例如在事务 ，但不是Capybara）。

You can't run capybara code once and then run all the tests. You always start from scratch. Your proposed solution with before(:each) or helper method is the only posibility. (It's possible to run some ruby before(:all) e.g. create objects outside the transaction check here but not Capybara)

为了加快规格，您可以在单独的规格中测试登录功能，然后以某种方式对身份验证进行存根验证，但这取决于您的实现。

To speed up your specs you can test login feature in separate spec and then somehow stub the authentication but it depends on your implementation.
