Here's a couple of reasons off the top of my head:

1) You can hook your selenium tests into your build process (and hence your CI process).

2) You can use JUnit assertions.

3) You can build up multiple suites of JUnit tests (which can then be run in parallel).

I'm sure there's more but I guess it depends on the number of tests you have and the size of the project you are working on. If you're project already has a set of JUnit tests then it's quite nice to be able to write selenium tests without too much effort.

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("your@email.here");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

The proper way is to wait explicitly for the product to be added to the cart. Something changes on the page after the operation finishes, right? So wait for that change to occur! I don't know your webpage, obviously, but something along the lines:

// earlier
import static org.openqa.selenium.support.ui.ExpectedConditions.*;

// also earlier, if you want, but you can move it to the loop
WebDriverWait wait = new WebDriverWait(driver, 10);

Iterator<WebElement> button = T2.iterator();
while(button.hasNext()) {
    // find the current number of products in the cart
    String numberOfProductsInCart = driver.findElement(By.id("cartItems")).getText();
    button.next().click();
    // wait for the number of items in cart to change
    wait.until(not(textToBePresentInElement(By.id("cartItems"), numberOfProductsInCart)));
}

You can run a single feature file by using cucumber.options which will override all the options you have in the @CucumberOptions annotation:

mvn test -Dcucumber.options="src/test/features/com/perspecsys/salesforce/featurefiles/Account.feature"

EDIT (Jun 2021): Subsequent versions removed the cucumber.options construct and replaced it. One way to achieve the same result now is through the use of tags. Place a tag on top of your feature file (example @feature_file_name) and then run the following command:

mvn test -Dcucumber.filter.tags='@feature_file_name'

By definition, any widget that has focus also has the cursor. So driver.switchTo().activeElement() will return the currently focused WebElement. It doesn't actually change anything, just returns the active element. You can call

expectedElement.equals(driver.switchTo().activeElement());

to verify that expectedElement has focus.

Ok after 2 weeks I admit defeat and are using a workaround which works great for me at the moment.

The problem:
It is too difficult to port HTMLUnit to Android (or at least with my level of expertise). I am sure its a worthwhile project (and not that time consuming for experienced java programmer) . I emailed the guys at HTMLUnit and they commented that they are not looking into a port or what effort will be involved but suggested anyone who wants to start with such a project should send an message to their mailing list to get more developers involved (http://htmlunit.sourceforge.net/mail-lists.html).

The workaround:
I used android's built in WebView and overrided the onPageFinished method of Webview class to inject Javascript that grabs all the html after the page has fully loaded. Webview can also be used to called futher javascript actions, clicking buttons, filling in forms etc.

Code:

webView.getSettings().setJavaScriptEnabled(true);
MyJavaScriptInterface jInterface = new MyJavaScriptInterface();
webView.addJavascriptInterface(jInterface, "HtmlViewer");

webView.setWebViewClient(new WebViewClient() {

    @Override
    public void onPageFinished(WebView view, String url) {
       //Load HTML
       webView.loadUrl("javascript:window.HtmlViewer.showHTML('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
    }

}

webView.loadUrl(StartURL);
ParseHtml(jInterface.html);   

public class MyJavaScriptInterface {

    public String html;

    @JavascriptInterface
    public void showHTML(String _html) {
        html = _html;
    }
}

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")));

https://stackoverflow.com/questions/20009211/getting-selenium-to-pause-for-x-seconds

You can also check pageloaded using following code

IWait<IWebDriver> wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

 wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll down some pixel and scroll up

For Scroll down:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollBy(0,250)");

OR, you can do as follows:

jse.executeScript("scroll(0, 250);");

For Scroll up:

jse.executeScript("window.scrollBy(0,-250)");
OR,
jse.executeScript("scroll(0, -250);");

Scroll to the bottom of the page:

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll to the bottom of the page

Way 1: By using JavaScriptExecutor

jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

Way 2: By pressing ctrl+end

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL, Keys.END);

Way 3: By using Java Robot class

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_CONTROL);

All You Need To Know About Automation Testing Life Cycle

Nowadays, project managers and developers face the challenge of building applications with minimal resources and within an ever-shrinking schedule. No matter the developers have to do more with less, it is the responsibility of organizations to test the application adequately, quickly and thoroughly. Organizations are, therefore, moving to automation testing to accomplish this goal efficiently.

Testing A Progressive Web Application With LambdaTest

Developers have been trying to fully implement pure web based apps for mobile devices since the launch of iPhone in 2007, but its only from last 1-2 years that we have seen a headway in this direction. Progressive Web Applications are pure web-based that acts and feels like native apps. They can be added as icons to home and app tray, open in full screen (without browser), have pure native app kind of user experience, and generates notifications.

How Code Reviewing Can Help With Quality Assurance?

Being in the software industry you may have often heard the term code review. However, the concept of code reviewing is often misunderstood. Often it is overlooked in the software development life cycle as people feel performing testing should suffice the validation process. And so, they tend to turn a blind eye towards the code reviewing process. However, neglecting code reviewing process could bounce back with major consequences to deal with. We also have a misconception that code reviewing process is a responsibility for the development team alone. It is not! Code reviewing is a process that should involve not only developers but QAs and product managers too. This article is my attempt to help you realize the importance of code review and how as QA you should be participating in it. We will also look into code review best practices and code review checklist for test automation.

Monitoring Network Traffic With Automation Scripts

According to Wikipedia, “A test script in software testing is a set of instructions that will be performed on the system under test to test that the system functions as expected.” However, what purpose do these test scripts solve?
