I am currently doing a release of 2 major feature updates to a site. For me even with all my Drupal and web development skills releases are difficult, and far from stress free.
In examining new community modules I found the Behat UI module. Behat UI provides a UI similar to the Rules UI module to create Behat scenarios to test business logic expectations. The Behat UI looks like this when you install the module onto your site:

Behat UI, create simple scenarios to test for conditions on the webapge. The whole scenario may then be downloaded to a file.
This looks awesome! It requires Behat on your development system (I would likely not run this on a Production system), and optionally Selenium if you want a real browser to test your website. For the administration of this module you simply provide the path(s) to the testing tools on the system:
Had I found this module about 2 weeks ago I believe I would have tried to add behavior tests for the new functionality I’m adding to the website. So I would have more confidence during the deployment process.
note: From the example video tutorial on the project page it appears like these tests take a small while to run. But this is ok with me as the tests are write-once, repeat on any server and they can be saved to a file in version control.
I will likely add this module to my set of Development modules used when making a website. Other modules in this list include: Devel, Maillog and Theme Developer.
