Testing ActionMailer multipart emails(text and html version) with RSpec

I'm currently testing my mailers with RSpec, but I've started setting up multipart emails as described in the Rails Guides here: http://guides.rubyonrails.org/action_mailer_basics.html#sending-multipart-emails

I have both mailer templates in text and html formats, but it looks like my tests are only checking the HTML portion. Is there a way to check the text template separately?

Is it only checking the HTML view because it's first in the default order?

I have done this way, I found it simpler since the content of both emails is gonna be similar except styles and markup.

context 'When there are no devices' do
  it 'makes sure both HTML and text version emails are sent' do
    expect(mail.body.parts.count).to eq(2)
    # You can even make sure the types of the part are `html` and `text`
  end

  it 'does not list any lockboxes to be removed in both types emails' do
    mail.body.parts.each do |part|
      expect(part.body).to include('No devices to remove')
    end
  end
end
