Protractor- Generic wait for URL to change

Question

In previous questions I have seen that a nice way to wait for the url to change is to use:

browser.wait( function() {
    return browser.getCurrentUrl().then(function(url) {
        return /myURL/.test(url);
    });
}, 10000, "url has not changed");`

But I am trying to have a method that I can pass myURL as a variable (in case I need to use it with other sites) and is not working.

I am trying this in my Page Object file:

this.waitUrl = function(myUrl) {
    browser.wait( function(myUrl) {
        return browser.getCurrentUrl().then(function(url, myUrl) {
            return myUrl.test(url);
        });
    }, 10000, "url has not changed");
};

Any ideas if this is even possible and how to do it if so?

Solution 1

Update (July 2016): with Protractor 4.0.0 you can solve it with urlIs and urlContains built-in Expected Conditions.

Original answer:

Don't pass myUrl inside the then function, it is available from the page object function scope:

browser.wait(function() {
    return browser.getCurrentUrl().then(function(url) {
        return myUrl.test(url);
    });
}, 10000, "url has not changed");

I would though define it as an Expected Condition:

function waitUrl (myUrl) {
    return function () {
        return browser.getCurrentUrl().then(function(url) {
            return myUrl.test(url);
        });
    }
}

So that you can then use it this way:

browser.wait(waitUrl(/my\.url/), 5000);

Solution 2

For those that want an example for Protractor 4.0.0 through 5.3.0

You can use "ExpectedConditions" like so...

var expectedCondition = protractor.ExpectedConditions;
// Waits for the URL to contain 'login page'.
browser.wait(expectedCondition.urlContains('app/pages/login'), 5000);

If you want to validate this with an e2e test.

it('should go to login page', function() {
    loginPage.login();
    const EC = protractor.ExpectedConditions;

    browser.wait(EC.urlContains('app/pages/login'), 5000).then(function(result) {
        expect(result).toEqual(true);
    });

});

Hi, thanks for the response. Tried both and got this: Message: TypeError: myUrl.test is not a function Stacktrace: TypeError: myUrl.test is not a function at

@JamesBe ah, sure, you are using the regular expression match, so your url passed into the expected condition has to be a regular expression. Updated the answer.

@JamesBe you can also pass in a string and make a regular expression object via new Regexp(myUrl).

Legend! Thanks alecxe!

instead of "myUrl.test(url)" you can include anything that resolves to true when myUrl and url match, such as myUrl.include(url)
