Michael Hartl的教程第10.2.2章，列出失败的10.26测试

Question

Going through Hartl's tutorial and have searched for an answer, but found none. (There may be answers existing but becuase the chapters have been updated and switched around in the newer editions I can't find them if they exist.)

I am at section 10.2.2. listing 10.26 doing the rails test.

here is the error for my tests:

ERROR["test_should_redirect_edit_when_logged_in_as_wrong_user", UsersControllerTest, 1.5802158990409225]

    end

end

Why am I getting 2 failed tests when the book says that all tests should pass? I have looked at the lines the error message mentions ,but I am not sure what is wrong. Thanks for the help.

EDIT: Sessions controller

class SessionsController < ApplicationController
  def new
  end

  def create

    @user = User.find_by(email: params[:session][:email].downcase)

    if @user && @user.authenticate(params[:session][:password])
    log_in @user
    params[:session][:remember_me] == '1' ? remember(@user) : forget(@user) 
    redirect_to @user

    else
    flash.now[:danger] = 'Invalid email/password combination' # Not quite right!
    render 'new'
    end
  end

  def destroy
    log_out if logged_in?
    redirect_to root_url
  end
end

Answer 1

You're missing a closing angle bracket in the password_digest for the "Sterling Archer" test fixture.

password_digest: <%= User.digest('password') %

should be

password_digest: <%= User.digest('password') %>

Answer 2

look more attentively at line:

BCrypt::Errors::InvalidHash: invalid hash
            app/controllers/sessions_controller.rb:9:in `create'

You did not specify the code for this controller, and I can not tell you what might be wrong.
