How to use getDistributor method of org.openqa.selenium.grid.distributor.config.DistributorOptions class

To build on the answer of stevecross, note that the suggested expression is pretty lenient. For example, it will match this:

String xyz =" ID: VERSION: "

You can be more strict in your matching if needed. Say, if you need to ensure non-blank words, use + instead of * like this:

assertThat(xyz).matches("[A-Za-z]+ +ID: [0-9]+ +VERSION: [0-9]+");

And if you need to have exactly three spaces between the key-value pairs, then add {3} to a class of characters including only space ([ ]), like this:

assertThat(xyz).matches("[A-Za-z]*[ ]{3}ID: [0-9]*[ ]{3}VERSION: [0-9]*");

I find online regex evaluators helpful. See for example this one: https://regex101.com/

Google shrinks their css classes etc., so it is not easy to identify everything.

Also you have the problem that you have to "wait" until the site shows the result. I would do it like this:

public static void main(String[] args) {

    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    WebElement element = driver.findElement(By.name("q"));
    element.sendKeys("Cheese!\n"); // send also a "\n"
    element.submit();

    // wait until the google page shows the result
    WebElement myDynamicElement = (new WebDriverWait(driver, 10))
              .until(ExpectedConditions.presenceOfElementLocated(By.id("resultStats")));

    List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));

    // this are all the links you like to visit
    for (WebElement webElement : findElements)
    {
        System.out.println(webElement.getAttribute("href"));
    }
}

This will print you:

• http://de.wikipedia.org/wiki/Cheese
• http://en.wikipedia.org/wiki/Cheese
• http://www.dict.cc/englisch-deutsch/cheese.html
• http://www.cheese.com/

elementToBeClickable is used for checking an element is visible and enabled such that you can click it.

ExpectedConditions.elementToBeClickable returns WebElement if expected condition is true otherwise it will throw TimeoutException, It never returns null.

So if your using ExpectedConditions.elementToBeClickable to find an element which will always gives you the clickable element, so no need to check for null condition, you should try as below :-

WebDriverWait wait = new WebDriverWait(Scenario1Test.driver, 10); 
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[@id='brandSlider']/div[1]/div/div/div/img)[50]")));
element.click();

As you are saying element.click() passes both on link and label that's doesn't mean element is not clickable, it means returned element clicked but may be there is no event performs on element by click action.

Note:- I'm suggesting you always try first to find elements by id, name, className and other locator. if you faced some difficulty to find then use cssSelector and always give last priority to xpath locator because it is slower than other locator to locate an element.

Hope it helps you..:)

According to the source:

Wrapper for a condition, which allows for elements to update by redrawing. This works around the problem of conditions which have two parts: find an element and then check for some condition on it. For these conditions it is possible that an element is located and then subsequently it is redrawn on the client. When this happens a {@link StaleElementReferenceException} is thrown when the second part of the condition is checked.

So basically, this is a method that waits until a DOM manipulation is finished on an object.

Typically, when you do driver.findElement that object represents what the object is.

When the DOM has manipulated, and say after clicking a button, adds a class to that element. If you try to perform an action on said element, it will throw StaleElementReferenceException since now the WebElement returned now does not represent the updated element.

You'll use refreshed when you expect DOM manipulation to occur, and you want to wait until it's done being manipulated in the DOM.

Example:

<body>
  <button id="myBtn" class="" onmouseover="this.class = \"hovered\";" />
</body>

// pseudo-code
1. WebElement button = driver.findElement(By.id("myBtn")); // right now, if you read the Class, it will return ""
2. button.hoverOver(); // now the class will be "hovered"
3. wait.until(ExpectedConditions.refreshed(button));
4. button = driver.findElement(By.id("myBtn")); // by this point, the DOM manipulation should have finished since we used refreshed.
5. button.getClass();  // will now == "hovered"

Note that if you perform say a button.click() at line #3, it will throw a StaleReferenceException since the DOM has been manipulated at this point.

In my years of using Selenium, I've never had to use this condition, so I believe that it is an "edge case" situation, that you most likely won't even have to worry about using. Hope this helps!

You can get the element color(Background color of element) by:

element.getCssValue("background-color");

You can get the element text/caption color by:

element.getCssValue("color");

For example if you want to get the background and text color of "Sign in" button for LinkedIn, the code is as follows:

driver.get("https://www.linkedin.com/");
        String buttonColor = driver.findElement(By.name("submit")).getCssValue("background-color");
        String buttonTextColor = driver.findElement(By.name("submit")).getCssValue("color");
        System.out.println("Button color: " + buttonColor);
        System.out.println("Text color " + buttonTextColor);

This error message...

2018-08-31 09:16:26,570 ERROR [io.undertow.request] (default task-1) UT005023: Exception handling request to /crawlerClass/myCrawler/5922: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your base exception is the org.openqa.selenium.WebDriverException as your program Timed out waiting for driver server to start because of the following reason:

• Your JDK version is 1.8.0_92 which is pretty ancient.

So there is a clear mismatch between the JDK v8u92 and current Selenium Client v3.14.0.

Solution

• Upgrade JDK to recent levels JDK 8u181.
• Upgrade Selenium to current levels Version 3.14.0.
• Upgrade ChromeDriver to current ChromeDriver v2.41 level.
• Keep Chrome version between Chrome v66-68 levels. (as per ChromeDriver v2.41 release notes)
• Take a System Reboot.
• Execute your @Test.

Your variable represents something you want to do with a web element (in this case, click on it).

The appropriate type for that is not String. Use a Consumer<WebElement> instead (or whatever the type of what driver.findElement() returns is):

Consumer<WebElement> command = e -> e.click();

// ...

command.accept(driver.findElement(By.id("id1")));

This is type-safe, efficient, refactorable, and much more flexible than reflection (since your consumer can do whatever it wants with the element, not limited to a single method call without any argument. Like for example, enter some text in a text field)

for (String handle : driver.getWindowHandles()) {
    driver.switchTo().window(handle);
    System.out.println(String.format("handle: %s, url: %s", handle, driver.getWebDriver().getCurrentUrl()));
} 

 System.setProperty(CHROME_PROPERTY, LINUX_CHROMEDRIVER_PATH); // OS and Browser options
 ChromeOptions options = new ChromeOptions(); // create options instance
 options.addArguments("--headless"); // add an option
 driver = new ChromeDriver(options); // create a driver with the specific options instance

You just need to create a ChromeOptions object in which you need to save the options for your own driver. To add your own options just use this: options.addArguments(); and in the parenthesis insert your option in string mode.

I think this is going to work.
