How to use browser.wait() to wait for URL to change?

Hi

I want to write a Protractor test that waits until the current URL to change, so I have been looking at browser.wait(), combined with browser.getCurrentUrl().

However, I am not sure of how to use the two together: the browser.wait() method accepts as its first parameter a function that will return a boolean value – however, browser.getCurrentUrl() returns a promise.

My first attempt, which failed (as I expected), looks like this:

var currentUrl;
browser.getCurrentUrl().then(function (url) {
    currentUrl = url;
}).then(function () {
    return browser.wait(function () {
        return browser.getCurrentUrl().then(function (url) {
            return url !== currentUrl;
        });
    });
}).then(function () {
    // continue testing
});

Can anyone help?

many thanks

Ok, I know this is way way late but I believe you can do something like this:

var EC = browser.ExpectedConditions;
browser.wait(EC.urlContains('Expected URL'), timeout); // Checks that the current URL contains the expected text
browser.wait(EC.urlIs('Expected URL'), timeout); // Checks that the current URL matches the expected text

In case it may help others in future, here is the method I have written to wait for the URL to change to a particular value (as specified by a regex) :

/**
 * @name waitForUrlToChangeTo
 * @description Wait until the URL changes to match a provided regex
 * @param {RegExp} urlRegex wait until the URL changes to match this regex
 * @returns {!webdriver.promise.Promise} Promise
 */
function waitForUrlToChangeTo(urlRegex) {
    var currentUrl;

    return browser.getCurrentUrl().then(function storeCurrentUrl(url) {
            currentUrl = url;
        }
    ).then(function waitForUrlToChangeTo() {
            return browser.wait(function waitForUrlToChangeTo() {
                return browser.getCurrentUrl().then(function compareCurrentUrl(url) {
                    return urlRegex.test(url);
                });
            });
        }
    );
}
