How can I wait for a condition?

Question

I\'m new on protractor, and I\'m trying to implement an e2e test. I don\'t know if this is the right way to do this, but... The page that I want to test is not a full angula

Answer 1

I finally find out...

   var waitLoading = by.css('#loading.loader-state-hidden');

   browser.wait(function() {
       return ptor.isElementPresent(waitLoading);
   }, 8000);

   expect(ptor.isElementPresent(waitLoading)).toBeTruthy();

   var openContact = by.xpath("//a[@href='#/contacts']");
   element(openContact).click();

With this protractor could wait for that element until it loading page disappears. Thanks for those who tried to help XD.
