What's wrong?

No encapsulation

No Separation of Concerns

Violation of the DRY principle

Dependency on implementation details

Tight coupling

The Cure: PageObjects.

PageObjects

Tests

PageObjects Summary

The public methods represent the services that the page offers

Try not to expose the internals of the page

Generally don't make assertions

Methods return other PageObjects

Need not represent an entire page

Different results for the same action are modelled as different methods

Questions?
