    text
    copied!<p>There is a lot info about how to test mailers.</p> <p>But I haven't found any resources how to test mailer to check if they REALLY use correct template.</p> <p>example:</p> <pre><code>class NewsletterMailer &lt; ActionMailer::Base include SendGrid default from: -&gt; { SystemConfiguration.newsletter_from_email } def send_newsletter_to_groups(newsletter_campaign_id, group_ids) newsletter_campaign = NewsletterCampaign.find newsletter_campaign_id emails = Group.where(:id =&gt; group_ids).map(&amp;:emails).flatten build_and_send_email(newsletter_campaign, emails) end end </code></pre> <p>on <code>app/views/newsletter_mailer/send_newsletter_to_group.html.erb</code> I have <strong>typo</strong>.</p> <p>I wrote <code>send_newsletter_to_group.html.erb</code> instead of <code>send_newsletter_to_groups.html.erb</code></p> <p>My spec still pass:</p> <pre><code>require "spec_helper" describe NewsletterMailer do before { create(:system_configuration) } let(:newsletter) { create(:newsletter_campaign) } describe '.send_newsletter_to_groups' do before do create(:system_configuration) create_list(:group, 3) create_list(:user, 2, groups: [Group.first], newsletter_subscription: true) create_list(:user, 2, groups: [Group.last], newsletter_subscription: true) create_list(:user, 2, name: "pippo") end let(:group_ids) { Group.pluck(:id) } subject { NewsletterMailer.send_newsletter_to_groups(newsletter.id, group_ids) } its(:to) { should == User.where("name != 'pippo'").map(&amp;:email) } its(:from) { should be_present } its(:subject) { should be_present } end end </code></pre> <p>But email doesn't contain body.</p> <p>It just send blank email, cuz at the name of the partial (<code>send_newsletter_to_group.html.erb</code>) I got typo.</p> <p>How to test this? In Mailer.</p>
