Capturing emails in Acceptance tests with Specflow

Published on Tuesday, 18 November 2014

Pretty much every web application out there nowadays needs to send emails, whether it be for registration, password reset or some other bespoke functionality. When you’re working in your own dev environment and building out features, tools like smtp4dev work great for capturing emails sent to localhost; to use, simply add the following to web.config

<system.net>
  <mailSettings>
    <smtp deliveryMethod="Network">
      <network host="localhost" port="25" defaultCredentials="true" />
    </smtp>
  </mailSettings>
</system.net>

start smtp4dev.exe
