This javascript

function test() {arr = 111; return arr;}; 
test();

Calls the method test() but doesn't do anything with the result, ie. doesn't return it to the caller.

int a = (Integer) js.executeScript(testJS);

will return null and try to be dereferenced which will fail because dereferencing null throws NullPointerException.

Javadoc for JavascriptExecutor.html#executeScript(java.lang.String, java.lang.Object...)

Maybe you want the javascript

function test() {arr = 111; return arr;}; 
return test();

This works for me

System.setProperty("webdriver.chrome.driver", "C:\\Users\\me\\Downloads\\chromedriver.exe");
ChromeDriver driver = new ChromeDriver();
JavascriptExecutor executor = (JavascriptExecutor) driver;
String js = "function test() {" +
            "arr = 111; return arr;" +
            "}; return test()";
Long a = (Long) executor.executeScript(js);
System.out.println(a);

Maybe the span element is hidden. If that's the case then use the innerHtml property:

By.css:

String kk = wd.findElement(By.cssSelector("#customSelect_3 span.selectLabel"))
              .getAttribute("innerHTML");

By.xpath:

String kk = wd.findElement(By.xpath(
                   "//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel')]"))
              .getAttribute("innerHTML");

"/.//" means "look under the selected element".

Implicit Wait and Explicit Waits doesn't work that way, they will maximum wait for element for the time duration specified, If they find the element before that next step would be executed.

If you want your test to wait for exact time duration, you may want to use.

Thread.sleep(Time duration in milliseconds);

You may want to refer Diff b/w Implict Wait and Explicit Wait

Explicit Waits : An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code.

Implicit Waits : 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.

Thread.sleep : In sleep code It will always wait for mentioned seconds, even in case the page is ready to interact after 1 sec. So this can slow the tests.

https://stackoverflow.com/questions/34422661/selenium-implicitlywait-not-working

To work with Selenium 3.4.0 & Mozilla Firefox 53.x you need to download the latest geckodriver v0.16.1 from here. Save it in your machine & provide absolute path of the geckodriver in your code.

Ensure that you have updated the pom.xml with the required dependency as follows:

<dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.4.0</version>
</dependency>

It is recommended to use the WebDriver interface rather than to use the FirefoxDriver implementation.

Your code will look like:

System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();       
driver.navigate().to("http://www.google.com");

Provide the following commands to flush out the previous dependencies, install the new dependencies & execute your test:

>mvn clean
>mvn install
>mvn test

Managed to solve this problem with the hint that Saurabh Gaur gave me

Here is my HTML document that I tested the application with, its called Index.html:

<html>
<head>
    <title>I am the title, haha!</title>
</head>
<body>
    <p id="id1">I am id1</p>
    <a href="www.google.com" id="ihatejava">end my suffering</a>
<body>
</html>

and here is my java code. all it does is add a listener to the HTML elements:

public class Main extends Application {

public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage stage) throws MalformedURLException {
    WebView webView = new WebView();
    WebEngine engine = webView.getEngine();
    engine.load(new File("PATH/TO/Index.html").toURI().toURL().toExternalForm());

    Scene scene = new Scene(webView);
    stage.setScene(scene);
    stage.show();

    //we need this to check if the document has finished loading, otherwise it would be null and throw a exception
    engine.getLoadWorker().stateProperty().addListener((obs, oldState, currentState) -> {
        if (currentState == State.SUCCEEDED) {
            Document doc = engine.getDocument();
            addListeners(doc);
        }
    });
}

private void addListeners(Document doc) {
    Element link1 = doc.getElementById("id1");
    ((EventTarget) link1).addEventListener("click", e -> {
        System.out.println("id1 was clicked!");
    }, false);

    Element link2 = doc.getElementById("ihatejava");
    ((EventTarget) link2).addEventListener("click", e -> {

    }, false);
}

selenium doesn't support it, only web page shots. However you can use Robot to do it

try {
    String format = "jpg";
    String fileName = printScreen." + format;

    Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
    Robot robot = new Robot();
    BufferedImage screenFullImage = robot.createScreenCapture(screenRect);
    ImageIO.write(screenFullImage, format, new File(fileName));

} catch (AWTException | IOException ex) {
    System.err.println(ex);
}

And in C#

using System.Drawing;
using System.Drawing.Imaging;
using System.Windows.Forms;

Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics graphics = Graphics.FromImage(bitmap);
graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
bitmap.Save(@"C:\ScreenShots\printScreen.jpg", ImageFormat.Jpeg);
