Automation can help this by allowing you to accumulate your test cases over the life of the application so that both existing and new features can always be tested.

Ironically, when test time is short, testers will often sacrifice regression testing in favor of testing new features. The irony is that

the greatest risk to the user is in the existing features, not the new ones! If something the customer is already doing stops working – or worse, starts doing the wrong thing – then you could halt operations. The loss of a new feature may be inconvenient or even embarrassing, but it is unlikely to be devastating. But this benefit will be lost if the automated tests are not designed to be maintainable as the application changes. If they either have to be rewritten or require significant modifications to be reused, you will keep starting over instead of building on prior efforts. Therefore, it is essential to adopt an approach to test library design that supports maintainability over the life of the application.

Leverage

True leverage from automated tests comes not only from repeating a test that was captured while performed manually, but from executing tests that were never performed manually at all. For example, by generating test cases programmatically, you could yield thousands or more - when only hundreds might be possible with manual resources. Enjoying

Lean start-ups, in contrast, begin by searching for a business model…
