I am testing a page where server-side RSA keypair generation occurs after the page has completely loaded. This process takes between 5 to 20 seconds with my current setup, during which time the user must wait until the browser receives the keypair.
Although I have been using browser.sleep(), waiting for 20 seconds even if the keypair is generated in 5 seconds is frustrating. I attempted to use Protractor's evaluate() method as a while loop condition, but discovered that evaluate() returns an ElementFinder instead of the argument's value. Is there a different approach that allows Jasmine/Protractor to calculate a boolean value similar to how Jasmine evaluates toBe/toEqual/etc?
In summary,
expect(controller.evaluate('data.step1.done')).toBe(true);
This code snippet calculates a boolean value equal to the value of evaluate()'s argument in Angular's scope, and then compares it against "true". Is there a way to leverage this computed value or compute it manually?
