How can I wait for a condition?

Protractor 1.7.0 has also introduced a new feature: Expected Conditions.

There are several predefined conditions to explicitly wait for. In case you want to wait for an element to become present:

var EC = protractor.ExpectedConditions;

var e = element(by.id('xyz'));
browser.wait(EC.presenceOf(e), 10000);

expect(e.isPresent()).toBeTruthy();
