We are working on a large Umbraco 7.x enterprise website which has regular builds.

With the size of this product, to retrofit unit testing and/or Selenium would be cost prohibitive as the priority is to complete more features.

Has anyone come across any smart ways to automate regression testing with a reasonable amount of coverage to prevent bugs and decrease the amount of time for checking quality.

Or are there any community or commercial packages that could aid an uplift?

Many thanks, Peter
