Following the Rails Tutorial by Michael Hartl, I am testing for the <title> of my static pages with Minitest in Rails.
Here is the static_pages_controller_test.rb file:
require 'test_helper'
class StaticPagesControllerTest < ActionController::TestCase
test "should get home" do
get :home
assert_response :success
assert_select "title", "Home | Microblog"
end
test "should get help" do
get :help
assert_response :success
assert_select "title", "Help | Microblog"
end
test "should get about" do
get :about
assert_response :success
assert_select "title", "About | Microblog"
end
end
Here is the Home page home.html.erb file:
<!DOCTYPE html>
<html>
<head>
<title>Home | Microblog</title>
</head>
<body>
<h1>Microblog</h1>
<p>
This is the homepage for Microblog, a brand new microblogging app.
</p>
</body>
</html>
help.html.erb and about.html.erb basically contain the same content, with slight variations.
So, from my understanding, tests should pass.
However, when I run rake, I get:
Run options: --seed 47355

In particular, I don't understand why I get:
<Home | Microblog> expected but was
<Home | Microblog>..
What am I missing?
UPDATE: I went on with the tutorial and followed the guidelines in the Advanced testing setup section.
Here is what I get when I run all the tests with Guard:

I kept investigating the causes of the problem but did not find anything conclusive so far.
Any idea?
So, I kept following the tutorial, and in the next chapter (Chapter 4), at some point, we create the
full_titlehelper and remove the <% provide(:title, "Home") %> from the views.I am not sure how, but this solved the problem and made the tests to pass:
Hope that helps if you stumble upon the same issue.
