JavascriptExecutor

JavascriptExecutor is the Selenium interface which is being implemented by all the following classes:

FirefoxDriver
ChromeDriver
InternetExplorerDriver
EdgeDriver
OperaDriver
SafariDriver
RemoteWebDriver
EventFiringWebDriver
HtmlUnitDriver

While you execute your Selenium script at times because of cross domain policies browsers enforce your script execution may fail unexpectedly and without adequate error logging. This is particularly pertinent when creating your own XHR request or when trying to access another frame.

You will find a detailed discussion in Uncaught DOMException: Blocked a frame with origin “http://localhost:8080” from accessing a cross-origin frame while listing the iframes in page

JavascriptExecutor interface provides two methods as follows:

executeScript(): This method executes JavaScript in the context of the currently selected frame or window. The script fragment provided will be executed as the body of an anonymous function. Within the script you need to use document to refer to the current document. Note that local variables will not be available once the script has finished executing, though global variables will persist.
executeAsyncScript(): This method executes an asynchronous piece of JavaScript in the context of the currently selected frame or window. Unlike executing synchronous JavaScript, scripts executed with this method must explicitly signal they are finished by invoking the provided callback. This callback is always injected into the executed function as the last argument.

Example

A couple of examples:

Using JS to enter text

String js = "arguments[0].setAttribute('value','"+inputText+"')"
((JavascriptExecutor) webDriver).executeScript(js, element);

Double click through JavaScript

new Actions(driver).moveToElement(myElem, posX, posY).perform();
((JavascriptExecutor)driver).executeScript(jsDoubleClick, myElem, posX, posY);

Sending variable character strings through executeScript()

String myValue = "80120804076";
WebElement pesel = driver.findElement(fldPesel);
jse.executeScript("arguments[0].value='" + myValue + "';", pesel);

You can't test if the HTTP status code is 404. This is explained in this other thread. The only way is to test for something in the page which can only be in your 404 error page. For instance:

assertTrue(driver.getTitle().contains("404"));

If you're not sure that your page contains something specific like 404 or Page not found. You could generate from the server a special tag code (e.g. a <meta> tag in the <head> section) and test for it with the WebDriver.

https://stackoverflow.com/questions/17657037/catching-a-404-error-with-selenium

driver.submit()

should work. If the order of the buttons in your DOM is always the same, this should work too:

driver.findElements(By.className("buttonLargeAlt")).get(0).click();

if it is the first buttonLargeAlt button on your page.

PhantomJS by default starts with no local-storage; see this discussion.

To enable local-storage via Selenium I have used the following Java code. Sorry, it has been too long since I have used C#, but I am confident the C# bindings have similar methods available.

DesiredCapabilities capabilities = DesiredCapabilities.phantomjs();
// Phantom options can only be set from CLI
List<String> cliArgs = new ArrayList<String>();
cliArgs.add("--local-storage-quota=5000");
Path local_storage_path = Files.createTempDirectory("PhantomLocalStorage-");
cliArgs.add("--local-storage-path=" + local_storage_path.toString());
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgs);
WebDriver driver = new PhantomJSDriver(capabilities);

Note that local_storage_path will not be deleted after you are done with it. If you need that, you can set up a hook as per this post. But I suspect in C# this part is going to be wildly different from Java.

https://stackoverflow.com/questions/44329087/using-the-same-session-for-phantomjs-at-each-run

First of all, I apologise because I had never worked on a grid before. I thought it will be a frame and will be easier to switch and then scroll to the element using JavascriptExecutor. But, alas! That's not the case for a grid.
And, there must be a table when a grid is involved.

Now, this is what has worked for me.

First click on any visible element on grid to get it into focus.

Then scroll the grid using grid's locator(xpath,id,etc.) using 'Keys.PAGE_DOWN' till you find the element you are looking for.

In case the element is not found on each scrolls, than handle the exception it raises and scroll again.

Note: Do not forget to give some sleep time after each scroll.

I have automated one sample grid, and have attached the sample working code below. Hope this helps in figuring out problem:

import java.io.IOException;

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class ScrollGrid{

    public static void main(String[] args) throws IOException, InterruptedException{


        WebDriver driver = new FirefoxDriver();
        driver.get("https://demos.devexpress.com/ASPxGridViewDemos/PagingAndScrolling/VirtualPaging.aspx");
        driver.manage().window().maximize();

        //Clicking on an element inside grid to get it into focus
        driver.findElement(By.xpath("//*[@id='ContentHolder_ASPxGridView1_DXMainTable']//td[.='9/30/1994']")).click();

        WebElement ele=null;
        int flag=0;
        int count=0;

        do{
            try{
                //element to search for while scrolling in grid
                ele = driver.findElement(By.xpath("//*[@id='ContentHolder_ASPxGridView1_DXMainTable']//td[.='3/28/1996']"));
                flag=1;
            } catch(Throwable e){
                //scrolling the grid using the grid's xpath
                driver.findElement(By.xpath("//*[@id='ContentHolder_ASPxGridView1']//div[2]")).sendKeys(Keys.PAGE_DOWN);
                Thread.sleep(3000);
            }
        }while((flag==0) || ((++count)==250));

        if(flag==1){
            System.out.println("Element has been found.!!");
        }else{
            System.out.println("Element has not been found.!!");
        }

        highlightElement(driver, ele); //For highlighting the element
        Thread.sleep(5000L); //to check if the element scrolled to is highlighted.
        driver.close();
    }

    //For highlighting the element to be located after scroll
    public static void highlightElement(WebDriver driver, WebElement ele) {
        try
        {
            for (int i = 0; i < 3; i++) 
            {
                JavascriptExecutor js = (JavascriptExecutor) driver;
                js.executeScript("arguments[0].setAttribute('style', arguments[1]);",ele, "color: red; border: 2px solid red;");
            }
        }
        catch(Throwable t)
        {
            System.err.println("Error came : " +t.getMessage());
        }
    }

}

Note: This works correctly now. It will come out of the loop in case the element is found, or if not found after 250 scrolls. '250' is a relative number. You can change it to the number of scrolls you want to perform on the grid.

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));
    }

After some hours I finally found a solution by using Actions without JavascriptExecuter:

Actions actions = new Actions(driver);
actions.moveToElement(website);
actions.click();
actions.sendKeys("Some Name");
actions.build().perform();

Well, it worked for me. However, is this way the better solution ?

Recently Selenium has launched Selenium 3 and if you are trying to use Firefox latest version then you have to use GeckoDriver:

System.setProperty("webdriver.gecko.driver","G:\\Selenium\\Firefox driver\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();

Why You Should Use Puppeteer For Testing

Over the past decade the world has seen emergence of powerful Javascripts based webapps, while new frameworks evolved. These frameworks challenged issues that had long been associated with crippling the website performance. Interactive UI elements, seamless speed, and impressive styling components, have started co-existing within a website and that also without compromising the speed heavily. CSS and HTML is now injected into JS instead of vice versa because JS is simply more efficient. While the use of these JavaScript frameworks have boosted the performance, it has taken a toll on the testers.

Why You Need To Care About Automated Functional Testing In 2020?

How many times have you come across products that have good UI but really bad functionality such as severe lagging experience and ample number of bugs or vice-versa. There could be multiple reasons for the product to go live, but it definitely gives an indication that thorough testing was not performed. There could be scenarios where a minor software update which was not tested for all the ‘corner scenarios’ could break the existing functionalities in a software product.
