jnicho02 / RailsBridge: do some testing
Last active July 6, 2017 10:58
Take a look at the Rails Guide to Testing: http://guides.rubyonrails.org/testing.html
Rails has unit testing using MiniTest by default.
When you ran the scaffolding it created a controller test /test/controllers/topics_controller_test.rb
Add to /test/models/topic_test.rb:
class TopicTest < ActiveSupport::TestCase
test "set a title" do
t = Topic.new

Cloud9 Rails5 Heroku update
Cloud9.io has a Rails template project, but it is Rails 4
Check that it is still Rails 4:
$ rails -v
Rails 5 needs ruby 2.2.2 minimum, but I belive that Cloud9 has 2.3.0p0....just check:
$ ruby -v
Update the rails installation to 5:
$ gem install rails

curl -o db/db.dump `heroku pg:backups --app open-plaques-beta public-url`
createdb openplaques_$(date +'%Y-%m-%d')
pg_restore -d openplaques_$(date +'%Y-%m-%d') db/db.dump
sed -iE "s/openplaques_[0-9|-]*/openplaques_$(date +'%Y-%m-%d')/g" config/database.yml
