Feature: `send_email` matcher
The `send_email` matcher is used to check if an email with the given parameters has been sent inside the expectation block.
NOTE: This matcher implies that the example(s) actually send email(s) using the test adapter, and *not* scheduled as a job to be sent in the background later.
To have an email sent in tests make sure:
- `ActionMailer` performs deliveries - `Rails.application.config.action_mailer.perform_deliveries = true`
- If the email is sent asynchronously (with `.deliver_later` call), ActiveJob uses the inline adapter - `Rails.application.config.active_job.queue_adapter = :inline`
- ActionMailer uses the test adapter - `Rails.application.config.action_mailer.delivery_method = :test`
If you want to check an email has been scheduled as a job, use the `have_enqueued_email` matcher.
Scenario: Checking email sent with the given multiple parameters
Given a file named "spec/mailers/notifications_mailer_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe NotificationsMailer , type: :mailer do
it "checks email sending by multiple params" do
expect {
NotificationsMailer.signup.deliver_now
}.to send_email(
from: 'from@example.com',
to: 'to@example.org',
subject: 'Signup'
)
end
end
"""
When I run `rspec spec/mailers/notifications_mailer_spec.rb`
Then the examples should all pass
Scenario: Checking email sent with matching parameters
Given a file named "spec/mailers/notifications_mailer_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe NotificationsMailer , type: :mailer do
it "checks email sending by one param only" do
expect {
NotificationsMailer.signup.deliver_now
}.to send_email(
to: 'to@example.org'
)
end
end
"""
When I run `rspec spec/mailers/notifications_mailer_spec.rb`
Then the examples should all pass
Scenario: Checking email not sent with the given parameters
Given a file named "spec/mailers/notifications_mailer_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe NotificationsMailer , type: :mailer do
it "checks email not sent" do
expect {
NotificationsMailer.signup.deliver_now
