Commitments are always left unfulfilled

Question

Commitments are always left unfulfilled

The code provided above seems to be experiencing issues as "post4" and "post3" are not showing up in the console log. The promise is returned, however, attempting to chain from that promise does not seem to work.

loginPage.prototype.doLogin = function(isGood){
    var d = webdriver.promise.defer();
    this.driver.findElement(webdriver.By.css('input.loginbutton')).click(function() {
        if(isGood){
            //return new statementPage;
            console.log("post3")
            d.fulfill(new statement.statementPage(this.driver));
        } else {
            console.log("post4")
            d.fulfill(this);
        }
    });
    console.log("post5")
    return d.promise;
}

If I try to execute

login.doLogin(true).then(function(){console.log("foo")})

, it won't display post3, post4, or foo in the log.

Even though other promises are working correctly elsewhere in my code, this specific piece of code doesn't seem to be functioning properly.

Answer №1

The click method in webdriverjs does not require any parameters or callbacks, which means that your function was never executed. The source code for the click function can be found in the official API documentation:

webdriver.WebElement.prototype.click = function() {
  return this.schedule_(
      new webdriver.Command(webdriver.CommandName.CLICK_ELEMENT),
      'WebElement.click()');
};

You can see a demonstration of this behavior in action by visiting this JSFiddle link, where a JavaScript function without parameters behaves as expected if the arguments variable is used.

To ensure that your code runs after the click operation is completed, you can use the

element.click().then(function(){d.fulfill()});

syntax to handle promises effectively. For more information on promises in webdriverjs, refer to the official Webdriverjs Promises documentation.

Instead of relying on a callback like this:

element.click(function(){d.fulfill(););

It is recommended to utilize the promise returned by the click event, like so:

element.click().then(function(){d.fulfill()});
