Protractor timeouts

Question

I\'ve been developing automated tests in Protractor for quite some time and like many of you, I\'ve run into gaps which can only be crossed with the browser.sleep()

Answer 1

This is the way if you want to perform any action when element present or want to wait until it present on page.

    element(by.id).isPresent().then(function(result) {
            if (result) {
                nextButton.click();
            }
            else{
                browser.wait(function () {
                    return browser.isElementPresent(element(by.id));
                },50000);
            }
        }).then(function () {
            nextButton.click();
        });

    },

If you can devise some sort of test to determine if whatever you're waiting for has completed, you can use browser.wait. Taking ideas from from http://docsplendid.com/archives/209, you can pass a function that returns a promise that resolves to true or false, such as one that uses isPresent

browser.wait(function() {
  return element(by.id('some-element')).isPresent();
}, 1000);

or if you have some more complicated condition you can use promise chaining:

browser.wait(function() {
  return element(by.id('some-element')).isPresent().then(function(isPresent) {
    return !isPresent;
  });
}, 1000);

and the command flow will wait, repeatedly calling the function passed to wait, until the promise it returns resolves to true.
