CSC/ECE 517 Fall 2016/E1668.Test e-mailing functionality

Background

Expertiza is a peer review system where the students can submit their work and do reviews on fellow students’ work. Expertiza is an open source project and is based on “Ruby on Rails” framework. Expertiza facilitates easy creation of assignments and a list of topics for the same. It allows students to suggest a topic for an assignment as well. Students can form teams and invite other students to join their team for various assignments. Moreover, students can post team advertisements and describe the qualities they are looking for in their team members and other students can respond to the same. Expertiza overall gives a simple web interface for assignment management for both the students as well as instructors.

There are various ways to use e-mail functionality in the Expertiza. To name a few examples: users should get welcome emails once they register successfully, they should get reminder emails if they missed deadline of submission of their works, they should receive notification emails when other users review their homework, or others finish reviewing one of their reviews. All of these above are functions belongs to emailing. However, currently there is no test for these functions in the Expertise, which should be added to ensure valid usage of e-mailling features.

Project Objectives

We will write feature test to check the e-mailling functionality, RSpec will be used as the testing framework. Example such as assignment record or participant record will be written with the use of fixtures. We will also use Capybara to interacting with the Expertise. All possible valid or invalid cases for email functionality will be included in our tests.

Procedures

Prerequisite Configuration

We use Docker to set up the environment to test Expertiza functions, then we install the gem files and create the expertiza_text database in SQL. These are required before we do emailing testing:

   $ docker run --expose 3000 -p 3000:3000 -v /Users/andychen/Desktop/ruby_on_rails/expertiza-developer:/Users/andychen/Desktop/ruby_on_rails/expertiza-developer/expertiza -it update
   $ Bundle install
   $ /etc/init.d/mysql start           # start the MySQL
   $ rake db:migrate
   $ sudo apt-get install npm
   $ sudo npm install -g bower
   $ sudo ln -s “$(which nodejs)” /usr/bin/node
   $ bower install --allow-root
   $ /etc/init.d/mysql start
   $ mysql -u root -p
   $ create database expertiza_test    # create the expertiza test database

Test email edition functionality

Our tests files are located in the email_notification_spec.rb and edit_emails_spec.rb. Below are the tests in the "edit_emails_spec.rb", whose functions mostly involve update emailing options in the profile page:

Testing email address can be edited successfully in the profile tab. Users can update their email addresses anytime by clicking the profile button in the header after they log in. They can fill in the new address in the "E-maill address" tab. We test if new address can be filled in successfully by using Capybara:

   describe 'email address' do
     it 'should edit email address' do
       fill_in 'E-mail address', with: 'ychen75@ncsu.edu'
       expect(find_field('E-mail address').value).to eq 'ychen75@ncsu.edu'
     end
   end

Testing email option functionality

Testing email option can be checked successfully in the profile tab. There are three attributes related to email functionality when we define a user: email_on_review, email_on_submission, email_on_review_of_review. These boolean values can be reset in the profile page under E-mail options checkbox can be checked/unchecked can be checked/unchecked successfully.

1) We first test that if the 'When someone else reviews my work' checkbox by using Capybara:

   context 'When someone else reviews my work' do
       it "should check 'When someone else reviews my work' option" do
         find(:css, "#user_email_on_review").set(true)
          review_box = find('#user_email_on_review')
         expect(review_box).to be_checked
       end
    end  

2) Then, test that if 'When someone else reviews my work' checkbox can be checked/unchecked successfully:

 context 'When someone else reviews my work' do
       it "should check 'When someone else reviews my work' option" do
         find(:css, "#user_email_on_review").set(true)
         review_box = find('#user_email_on_review')
         expect(review_box).to be_checked
       end
     it "should uncheck 'When someone else reviews my work' option" do
         find(:css, "#user_email_on_review").set(false)  
         review_box = find('#user_email_on_review')
         expect(review_box).not_to be_checked
       end
     end

3) Test that if the 'When someone else submits work I am assigned to review' checkbox can be checked/unchecked successfully:

   context 'When someone else submits work I am assigned to review' do
       it "should check 'When someone else submits work I am assigned to review' option" do
         find(:css, "#user_email_on_submission").set(true)
         review_box = find('#user_email_on_submission')
         expect(review_box).to be_checked
       end
 
       it "should uncheck 'When someone else submits work I am assigned to review' option" do
         find(:css, "#user_email_on_submission").set(false)
         review_box = find('#user_email_on_submission')
         expect(review_box).not_to be_checked
       end
   end

4) Test that if the "When someone else reviews one of my reviews (metareviews my work)" checkbox can be checked/unchecked successfully:

   context 'When someone else reviews one of my reviews (metareviews my work)' do
       it "should check 'When someone else reviews one of my reviews (metareviews my work)' option" do
         find(:css, "#user_email_on_review_of_review").set(true)
         review_box = find('#user_email_on_review_of_review')
         expect(review_box).to be_checked
       end
 
       it "should uncheck 'When someone else reviews one of my reviews (metareviews my work)' option" do
         find(:css, "#user_email_on_review_of_review").set(false)
         review_box = find('#user_email_on_review_of_review')
         expect(review_box).not_to be_checked
       end
     end

5) Test that if the "Send me copies of emails sent for assignments" checkbox can be checked/unchecked successfully:

   context 'Send me copies of emails sent for assignments' do
       it "should check 'Send me copies of emails sent for assignments' option" do
         review_box = find('#user_copy_of_emails')
         expect(review_box).to be_checked
       end
 
       it "should uncheck 'Send me copies of emails sent for assignments' option" do
         review_box = find(:css, "#user_copy_of_emails")
         expect(review_box).not_to be_checked
       end
     end

Below are the tests located in the email_notification_spec.rb file, we use a gem named 'capybara-email' to open the email we intend to send and check for the content for related mailing task:

Test password resetting emailing functionality

Testing email can be sent to users successfully if they reset their password. Users can reset their password if they forget about their previous ones. They can get a new password in email sent by the Expertiza system. We use capybara to test and check for password-reset content:

 feature 'Reset password mailer' do
   background do
     FactoryGirl.create :student
     # will clear the message queue
     clear_emails
     visit 'password_retrieval/forgotten'
     find('input#user_email', visible: false).set('expertiza@mailinator.com')
     click_button 'Request password'
     # will find an email sent to expertiza.development@gmail.com and set `current_email`
     open_email('expertiza.development@gmail.com')
   end

   scenario 'testing for content' do
     expect(page).to have_current_path('/password_retrieval/forgotten')
     expect(current_email).to have_content 'Your Expertiza password has been reset. We strongly recommend that you change the password the next time you access the application.'
     expect(current_email).to have_content 'User Name'
     expect(current_email).to have_content 'New password'
   end
 end

Testing signing-up emailing functionality

Testing welcome email can be sent to users successfully if they sign up successfully. Users will get welcome email once they get new accounts in the Expertiza, we use capybara to test and check for welcome email content:

 feature 'Welcome mailer' do
   background do
     create(:assignment)
     FactoryGirl.create :student
     # will clear the message queue
     clear_emails
     login_as("instructor6")
     visit '/users/new?role=Student'
     find('input#user_name', visible: false).set('Puma')
     find('input#user_fullname', visible: false).set('Qiaoxuan Xue')
     find('input#user_email', visible: false).set('expertiza@test.com')
     click_button 'Create'
     # Will find an email sent to expertiza.development@gmail.com and set `current_email`
     open_email('expertiza.development@gmail.com')
   end

   scenario 'testing for content' do
     expect(page).to have_current_path('/users/list')
     expect(current_email).to have_content 'Your Expertiza account has been created at http://expertiza.ncsu.edu. We strongly recommend that you change the password the first time you access the application.'
     expect(current_email).to have_content 'User Name'
     expect(current_email).to have_content 'E-mail address'
     expect(current_email).to have_content 'New password'
   end
 end

==Testing homework updating emailing functionality

Testing email notification can be sent to the users successfully once their assigned homework get updated. Each assignment are created with a contributor and reviewer, once the contributor updates their homework, the reviewer will receive a notification email informing about this action and view the update. We use capybara and check for the content for update email:

 feature 'update assignment email notification' do
   background do
     student = FactoryGirl.create :student
     assignment = FactoryGirl.create :assignment
     # will clear the message queue
     clear_emails
     Mailer.sync_message(
         recipients: 'expertiza.development@gmail.com',
         subject: "One of the assignment#{assignment.name} is updated, you can review it now",
         body: {
             home_page: '123',
             first_name: ApplicationHelper.get_user_first_name(student),
             name: student.name,
             password: student.password,
             partial_name: "update"
         }
     ).deliver_now
     open_email('expertiza.development@gmail.com')
   end

   scenario 'testing for content' do
     expect(current_email).to have_content 'One of the'
     expect(current_email).to have_content 'assignment has just been entered or revised.'
     expect(current_email).to have_content 'You may log into Expertiza and review the work now'
   end
 end

Testing reviewing notification emailing functionality

Testing email can be sent to the users successfully once their work get reviewed. Once a user's assignment get reviewed by a reviewer, a notification email will be sent to the user to check for the content of the review. We use capybara to test and check for the content for review email:

   feature 'New submission notification' do
     background do
       # using the method called same as response.rb => email
       student = FactoryGirl.create :student
       defn = {}
       defn[:body] = {}
       defn[:body][:partial_name] = 'new_submission'
       defn[:body][:first_name] = student.name
       # will clear the message queue
       clear_emails
       Mailer.sync_message(defn).deliver_now
       # Will find an email sent to expertiza.development@gmail.com and set `current_email`
       open_email('expertiza.development@gmail.com')
     end

     scenario 'testing for content' do
       expect(current_email).to have_content 'assignment has just been entered'
     end
   end
