Rspec doesn't reload changed password attribute - why?

问题

I am running Rails 3.2.1 and rails-rspec 2.8.1....When I run the test for resetting a user's password, it seems that reloading the user object doesn't load the new password attribute....

Here is the code for my test:

 describe "Reset password page" do
    let(:teacher) { FactoryGirl.create(:teacher, :email=>"jane@gmail.com")}
    let(:old_password) { teacher.password }
    before do
      visit reset_password_form_path
      fill_in "Email", with: teacher.email
      click_button "Reset Password"
    end
    it { should have_content('Your new password has been emailed to the address you provided.')}
    specify { Teacher.find_by_email("jane@gmail.com").password.should_not == old_password }
    ## specify { teacher.reload.password.should_not == old_password }  ##THIS FAILS
  end

specify { teacher.reload.password.should_not == old_password } FAILS but specify { Teacher.find_by_email("jane@gmail.com").password.should_not == old_password } PASSES

So this tells me the password is being saved correctly, but not being reloaded...any ideas why? I am using the Rails 3.2.x "has_secure_password" method for rolling the login/password features. This means a password_digest is what gets saved to the database, and password is a virtual attribute (I think).

回答1:

Just understood: let blocks are not loaded till you summon them.

So, because you didn't use old_password anywhere before:

teacher.reload.password.should_not == old_password

Is equivalent to:

teacher.reload.password.should_not == teacher.reload.password

That's why it just can't fail!

If you want it to fail correctly:

old_password #because it's triggered, the value is set and won't be set again
teacher.reload.password.should_not == old_password

Edit:

describe "Reset password page" do
  let(:teacher) { FactoryGirl.create(:teacher, :email=>"jane@gmail.com")}

  before do
    @old_password = teacher.password
    visit reset_password_form_path
    fill_in "Email", with: teacher.email
    click_button "Reset Password"
  end

  specify { teacher.reload.password.should_not == @old_password }
end
