One of my (very talented) former colleagues - Pedro Meza will be presenting a talk on testing your angular apps with Protractor.
As applications grow in size and complexity, it becomes unrealistic to rely on manual testing to verify the correctness of new features, catch bugs and notice regressions. Unit tests are the first line of defense for catching bugs, but sometimes issues come up with integration between components which can't be captured in a unit test. End to end tests are made to find these problems.
Protractor, is an end to end test runner which simulates user interactions that will help you verify the health of your Angular application.
