Should wrap webdriver's 'isElementPresent'

[juliemr]

Currently, isElementPresent won't work with all protractor bindings.

++ for that.

Slightly unrelated but probably not worth its own issue as fixing this will allow a fair amount of sugar...

Would be nice to get some methods like in CasperJS:

• waitUntilElementIsGone (or waitWhileSelector etc)
• waitUntilTextIs (or waitWhileTextIs)

etc etc. http://docs.casperjs.org/en/latest/modules/casper.html#waitwhileselector

Logically, seems like a combination of wait and find methods should be enough but... seems that the .wait(fn) does not quite work as expected and will iterate until true but does not seem to run .then or resume flow. protractor@#0.8.0

context:

// being able to wait for an element to disappear before doing something. exists initially
setTimeout(function(){
    // remove node after 2 sec   
    driver.executeScript(function() {
        var b = document.querySelector('.refresh-btn');
        b.parentNode.removeChild(b);
    });
}, 2000);

var gone;
ptor.wait(function(){
    gone = !ptor.isElementPresent(by.css('.refresh-btn'));
        gone || console.log('resolving at ' + +new Date); // runs a fair bit for 2 secs.
    return gone;
}).then(function(){
        console.log('never runs');
    expect(true).toBe(true);
});

// nope.
expect(false).toBeFalsy();
