Nightwatchjs: how to check if element exists without creating an error/failure/exception

Question

In the page I\'m testing, two buttons may be displayed: BASIC or ADVANCED.

I want to be able to tell if the ADVANCED button is showing -- and if so, click it.

Answer 1

The syntax could be little off. Not very familiar with NightWatchJS. However the concept remains same.

//I would not wait for a element that should not exist
//rather I would find the list of the element and see if the count is greater than 0
//and if so, we know the element exists
browser.findElements(webdriver.By.css('#advanced-search')).then(function(elements){
    if(elements.length> 0){
        console.log(elements.length);
    }
});
