How to use fromString method of org.openqa.selenium.firefox.Enum FirefoxBinary.Channel class

You can use WebDriverWait. From docs example:

 (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.findElement(...).getText().length() != 0;
            }
        });

Don't use meaningless XPath. Your error message tells you "NoSuchElement", so you had your locator wrong, which has nothing to do with getText (not yet). Try using CssSelector or meaningful XPath:

 driver.findElement(By.cssSelector("#ctrlNotesWindow .notesData > .notesDate")).getText();

It's not possible directly via the API, so you'll have to use a script injection.

The best way to determine if an element is visible in the viewport is to get the element at the supposed location with document.elementFromPoint. It returns null if it's not within the viewport and your element or a descendant if it is.

public static Boolean isVisibleInViewport(WebElement element) {
  WebDriver driver = ((RemoteWebElement)element).getWrappedDriver();

  return (Boolean)((JavascriptExecutor)driver).executeScript(
      "var elem = arguments[0],                 " +
      "  box = elem.getBoundingClientRect(),    " +
      "  cx = box.left + box.width / 2,         " +
      "  cy = box.top + box.height / 2,         " +
      "  e = document.elementFromPoint(cx, cy); " +
      "for (; e; e = e.parentElement) {         " +
      "  if (e === elem)                        " +
      "    return true;                         " +
      "}                                        " +
      "return false;                            "
      , element);
}

Effective January 15, 2020, The Central Repository no longer supports insecure communication over plain HTTP and requires that all requests to the repository are encrypted over HTTPS.

If you're receiving this error, then you need to replace all URL references to Maven Central with their canonical HTTPS counterparts:

Replace http://repo1.maven.org/maven2/ with https://repo1.maven.org/maven2/

Replace http://repo.maven.apache.org/maven2/ with https://repo.maven.apache.org/maven2/

If for any reason your environment cannot support HTTPS, you have the option of using our dedicated insecure endpoint at http://insecure.repo1.maven.org/maven2/

For further context around the move to HTTPS, please see https://blog.sonatype.com/central-repository-moving-to-https.

Write a method like this:

protected boolean isAlertPresent() {
        try {
          driver.switchTo().alert();
          return true;
        } catch (NoAlertPresentException e) {
          return false;
        }
      }

Call the above method to verify whether alert is present or not as below:

if(isAlertPresent()){
            System.out.println(isAlertPresent());
            driver.switchTo().alert().accept();
        }

Check the below links:

• Implicit Wait - It instructs the web driver to wait for some time by poll the DOM. Once you declared implicit wait it will be available for the entire life of web driver instance. By default the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/driver implementation.

• Explicit Wait + ExpectedConditions - It is the custom one. It will be used if we want the execution to wait for some time until some condition achieved.

I also had problems with accepting the warning for using a signed certificate. The solution of @eskoba worked like a charm. The functions are NOT final, because I let the enter button press for 10 times. I made this, because the webdriver needs a long time until it actually calls the url. In the meantime he starts pressing already.

In Python:

def threaded_function():
    #Calls the website
    browser.get(url)

def threaded_function2():
    #Presses 10 times
    for i in range(0,10):
        pyautogui.press('enter')

#Calling the website and pressing 10 times in the same time
thread2 = Thread(target = threaded_function2)
thread2.start()

thread = Thread(target = threaded_function)
thread.start()

Check this post, I wrote code to get an absolute XPath.

public static String getAbsoluteXPath(WebElement element)
{
    return (String) ((JavascriptExecutor) driver).executeScript(
            "function absoluteXPath(element) {"+
                    "var comp, comps = [];"+
                    "var parent = null;"+
                    "var xpath = '';"+
                    "var getPos = function(element) {"+
                    "var position = 1, curNode;"+
                    "if (element.nodeType == Node.ATTRIBUTE_NODE) {"+
                    "return null;"+
                    "}"+
                    "for (curNode = element.previousSibling; curNode; curNode = curNode.previousSibling) {"+
                    "if (curNode.nodeName == element.nodeName) {"+
                    "++position;"+
                    "}"+
                    "}"+
                    "return position;"+
                    "};"+

                    "if (element instanceof Document) {"+
                    "return '/';"+
                    "}"+

                    "for (; element && !(element instanceof Document); element = element.nodeType == Node.ATTRIBUTE_NODE ? element.ownerElement : element.parentNode) {"+
                    "comp = comps[comps.length] = {};"+
                    "switch (element.nodeType) {"+
                    "case Node.TEXT_NODE:"+
                    "comp.name = 'text()';"+
                    "break;"+
                    "case Node.ATTRIBUTE_NODE:"+
                    "comp.name = '@' + element.nodeName;"+
                    "break;"+
                    "case Node.PROCESSING_INSTRUCTION_NODE:"+
                    "comp.name = 'processing-instruction()';"+
                    "break;"+
                    "case Node.COMMENT_NODE:"+
                    "comp.name = 'comment()';"+
                    "break;"+
                    "case Node.ELEMENT_NODE:"+
                    "comp.name = element.nodeName;"+
                    "break;"+
                    "}"+
                    "comp.position = getPos(element);"+
                    "}"+

                    "for (var i = comps.length - 1; i >= 0; i--) {"+
                    "comp = comps[i];"+
                    "xpath += '/' + comp.name.toLowerCase();"+
                    "if (comp.position !== null) {"+
                    "xpath += '[' + comp.position + ']';"+
                    "}"+
                    "}"+

                    "return xpath;"+

                    "} return absoluteXPath(arguments[0]);", element);
}

This can actually be easily done.

The idea is to get access to the WebDriver instance and run the JavaScript on it (if it supports it). Then there's a lot of validating, because we need to make sure we only return what we promised.

The ByJavaScript class itself will look like this:

public class ByJavaScript extends By implements Serializable {
    private final String script;

    public ByJavaScript(String script) {
        checkNotNull(script, "Cannot find elements with a null JavaScript expression.");
        this.script = script;
    }

    @Override
    public List<WebElement> findElements(SearchContext context) {
        JavascriptExecutor js = getJavascriptExecutorFromSearchContext(context);

        // call the JS, inspect and validate response
        Object response = js.executeScript(script);
        List<WebElement> elements = getElementListFromJsResponse(response);

        // filter out the elements that aren't descendants of the context node
        if (context instanceof WebElement) {
            filterOutElementsWithoutCommonAncestor(elements, (WebElement)context);
        }

        return elements;
    }

    private static JavascriptExecutor getJavascriptExecutorFromSearchContext(SearchContext context) {
        if (context instanceof JavascriptExecutor) {
            // context is most likely the whole WebDriver
            return (JavascriptExecutor)context;
        }
        if (context instanceof WrapsDriver) {
            // context is most likely some WebElement
            WebDriver driver = ((WrapsDriver)context).getWrappedDriver();
            checkState(driver instanceof JavascriptExecutor, "This WebDriver doesn't support JavaScript.");
            return (JavascriptExecutor)driver;
        }
        throw new IllegalStateException("We can't invoke JavaScript from this context.");
    }

    @SuppressWarnings("unchecked")  // cast thoroughly checked
    private static List<WebElement> getElementListFromJsResponse(Object response) {
        if (response == null) {
            // no element found
            return Lists.newArrayList();
        }
        if (response instanceof WebElement) {
            // a single element found
            return Lists.newArrayList((WebElement)response);
        }
        if (response instanceof List) {
            // found multiple things, check whether every one of them is a WebElement
            checkArgument(
                    Iterables.all((List<?>)response, Predicates.instanceOf(WebElement.class)),
                    "The JavaScript query returned something that isn't a WebElement.");
            return (List<WebElement>)response;  // cast is checked as far as we can tell
        }
        throw new IllegalArgumentException("The JavaScript query returned something that isn't a WebElement.");
    }

    private static void filterOutElementsWithoutCommonAncestor(List<WebElement> elements, WebElement ancestor) {
        for (Iterator<WebElement> iter = elements.iterator(); iter.hasNext(); ) {
            WebElement elem = iter.next();

            // iterate over ancestors
            while (!elem.equals(ancestor) && !elem.getTagName().equals("html")) {
                elem = elem.findElement(By.xpath("./.."));
            }

            if (!elem.equals(ancestor)) {
                iter.remove();
            }
        }
    }

    @Override
    public String toString() {
          return "By.javaScript: \"" + script + "\"";
    }

}

^{This code uses the Google Guava library. It is a dependency of Selenium, so you should have it on your classpath. But if there's something you don't understand, look into Guava.}

Things to consider:

1. Document the whole thing.
2. Use better and more helpful exceptions. Consider some custom subclasses of WebDriverException. Also add more helpful messages and info.
3. Restrict the class' visibility to package. Or embed it into a static factory (as seen in the original By class) so that it won't be accessible directly etc.
4. Write tests. I have tried the most obvious usages (element can't be found, search from driver, search from some context) and everything seems to be ok, but I didn't test it extensively.

Usage:

WebElement elem = driver.findElement(new ByJavaScript("return document.querySelector('.haha');"));

Now, the original By class is a static factory that gives out various implementations of itself. Unfortunately, we can't add a new static method to it (without changing its source), so we won't be able to type By.javascript("return something;"). We have to create our own static factory to get something similar:

public class MyBy {
    /**
     * Returns a {@code By} which locates elements by the JavaScript expression passed to it.
     * 
     * @param script The JavaScript expression to run and whose result to return
     */
    public static By javascript(String script) {
        return new ByJavaScript(script);
    }
}

Usage:

WebElement elem = driver.findElement(MyBy.javascript("return document.querySelector('.haha');"));
