How to use Interface WebSocket class of org.openqa.selenium.remote.http package

Selenium won't wait for AJAX loading. It automatically waits for a page loading. To wait for AJAX type loading you have to use Implicit and Explicit wait.

You can use Implicit Wait and Explicit Wait to wait for a particular Web Element until it appears in the page. The wait period you can define and that is depends upon the application.

Explicit Wait:

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. If the condition achieved it will terminate the wait and proceed the further steps.

Code:

WebDriverWait wait = new WebDriverWait(driver,30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(strEdit)));

Or

WebElement myDynamicElement = (new WebDriverWait(driver, 30))
.until(new ExpectedCondition<WebElement>(){
@Override
public WebElement apply(WebDriver d) {
return d.findElement(By.id("myDynamicElement"));
}});

This waits up to 30 seconds before throwing a TimeoutException or if it finds the element will return it in 0 - 30 seconds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A successful return is for ExpectedCondition type is Boolean return true or not null return value for all other ExpectedCondition types.

You can use ExpectedConditions class as you need for the application.

Implicit Wait:

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available

Code:

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

One thing to keep in mind is that once the implicit wait is set - it will remain for the life of the WebDriver object instance

For more info use this link http://seleniumhq.org/docs/04_webdriver_advanced.jsp

You can use these waits during your AJAX loading.

I hope this will be helpful.

You are using latest version of Selenium WebDriver i.e. Selenium 3.x, this version of webdriver doesn't support direct firefox launch. You have to set the SystemProperty for webdriver.gecko.driver.

Replace the Code:-

WebDriver driver;
driver =new FirefoxDriver();

With This code:-

WebDriver driver;
System.setProperty("webdriver.gecko.driver", "<Path to your WebDriver>");
driver =new FirefoxDriver();

You can get the information about latest changes here

You can download the latest Gecko driver from here

I was seeing the same issue. The problem only appears when using Chrome 65 (currently: dev channel). With Chrome 64 (both stable channel and beta channel) everything worked fine.

It turns out I had an old chromedriver installed. Specifically, I was using chrome=65.0.3325.51 with chromedriver=2.29.461585. Running npm install -g chromedriver bumped chromedriver to 2.35.528157 and now the problem is solved.

TL;DR: run npm install -g chromedriver

FluentWait and WebDriverWait both are the implementations of Wait interface.

The goal to use Fluent WebDriver Explicit Wait and WebDriver Explicit Wait is more or less same. However, in few cases, FluentWait can be more flexible. Since both the classes are the implementations of same Wait interface so more or less both have the same feature except The FluentWait has a feature to accept a predicate or a function as an argument in until method. On the other hand, WebDriverWait accepts only function as an ExpectedCondition in until method which restricts you to use a boolean return only.When you use Predicate in FluentWait, it allows you to return any Object from until method.

Look at here carefully: https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/support/ui/FluentWait.html#until-com.google.common.base.Predicate-

Examples: A FluentWait having Function as an argument in until with String return:

public void exampleOfFluentWait() {
        WebElement foo = driver.findElement(By.id("foo"));
        new FluentWait<WebElement>(foo)
            .withTimeout(10, TimeUnit.SECONDS)
            .pollingEvery(2, TimeUnit.SECONDS)
                    .until(new Function<WebElement, String>() {
                        @Override
                        public String apply(WebElement element) {
                            return element.getText();
                        }
                    });
    }

The Same FluentWait having Function with Boolean return as an argument in until method.

public void exampleOfFluentWait() {
            WebElement foo = driver.findElement(By.id("foo"));
            new FluentWait<WebElement>(foo)
                .withTimeout(10, TimeUnit.SECONDS)
                .pollingEvery(2, TimeUnit.SECONDS)
                        .until(new Function<WebElement, Boolean>() {
                            @Override
                            public Boolean apply(WebElement element) {
                                return element.getText().contains("foo");
                            }
                        });
        }

One more FluentWait with Predicate.

public void exampleOfFluentWithPredicate() {
    WebElement foo = driver.findElement(By.id("foo"));
    new FluentWait<WebElement>(foo)
        .withTimeout(10, TimeUnit.SECONDS)
        .pollingEvery(100, TimeUnit.MILLISECONDS)
                .until(new Predicate<WebElement>() {
                    @Override
                    public boolean apply(WebElement element) {
                        return element.getText().endsWith("04");
                    }
                });
}

Example of WebDriverWait:

public void exampleOfWebDriverWait() {
        WebElement foo = driver.findElement(By.id("foo"));

        new WebDriverWait(driver, 10)
        .pollingEvery(2, TimeUnit.SECONDS)
        .withTimeout(10, TimeUnit.SECONDS)
        .until(ExpectedConditions.visibilityOf(foo));
    }

You can locate an element that loads after the initial page loads and then make Selenium wait until that element is found.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("ID")));

You can achieve this more easily by EventFiringWebDriver

EventFiringWebDriver is a wrapper around an arbitrary WebDriver instance which supports registering of a WebDriverEventListener, e.g. for logging purposes.

WebDriver driver = new FirefoxDriver();
//create an object of EventFiringWebDriver and pass the driver instance
EventFiringWebDriver wd = new EventFiringWebDriver(driver);
//create an object of  class WebDriverListener and pass the driver instance
WebDriverListener eventListener = new WebDriverListener(driver);
wd.register(eventListener);

Create a WebDriverListener class by implementing WebDriverEventListener interface

It has many methods like beforeClickOn, afterClickOn, beforeNavigateTo, afterNavigateTo, beforeFindBy, afterFindBy.These methods will automatically be called after respective actions ex : beforeFindBy and afterFindBy are called automatically before and after finding an element

   String title=""; //initially keep title empty
    //will automatically be called after click on an element
    public void afterClickOn(WebElement element, WebDriver driver) {

            //title is not equal to previous page title

            if(driver.getTitle()!=title){

            //take screenshot

            //assign the current title to string title
            title=driver.getTitle();

            }

        }

similarly you can override other methods specified above also for checking the title like afterNavigateTo and take screenshot when title of the page changes.

Hope this helps you...Kindly get back if you need any further help

The general principle is to check the value of window.pageYOffset in the browser. If your button scrolls completely back to the top then window.pageYOffset should have a value of 0. Assuming the driver variable holds your WebDriver instance:

JavascriptExecutor executor = (JavascriptExecutor) driver;
Long value = (Long) executor.executeScript("return window.pageYOffset;");

You can then check that value is 0. executeScript is used to run JavaScript code in the browser.

This answer initially mentioned scrollY but there's no support for it on IE. The MDN page on it, says:

For cross-browser compatibility, use window.pageYOffset instead of window.scrollY. Additionally, older versions of Internet Explorer (< 9) do not support either property and must be worked around by checking other non-standard properties. A fully compatible example:

var supportPageOffset = window.pageXOffset !== undefined;
var isCSS1Compat = ((document.compatMode || "") === "CSS1Compat");

var x = supportPageOffset ? window.pageXOffset : isCSS1Compat ? document.documentElement.scrollLeft : document.body.scrollLeft;
var y = supportPageOffset ? window.pageYOffset : isCSS1Compat ? document.documentElement.scrollTop : document.body.scrollTop;

Thanks to R. Oosterholt for the "heads up".

Finally this is what I tried and it worked.

You can simulate hit Enter key by adding "\n" to the entered text. For example textField.sendKeys("text you type into field" + "\n").
