How to use isLoaded method of org.openqa.selenium.support.ui.LoadableComponent class

You can select the element and use the send_keys method to send it the right/left arrow keys (which should increment/decrement the input). In Python:

from selenium.webdriver.common.keys import Keys
...
slider = page.find_element_by_id("sliderWidget")
for i in range(10):
  slider.send_keys(Keys.RIGHT)

That should increment the value by 10.

You have to add your dependencies to the classpath when you run your program:

java -cp "selenium-java.jar:..." -jar xyz-selenium-test-1.0.jar

Maven also allows you to run a Main class with all the required dependencies in the classpath (see option 1 in the previous link).

Otherwise you can create a Jar with dependencies, which will contain everything you need to run your code:

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>com.setup.test.Setup</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
      <id>make-assembly</id>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
</plugin>

and run

java -jar xyz-selenium-test-jar-with-dependencies-1.0.jar

The submit() function is there to make life easier. You can use it on any element inside of form tags to submit that form.

You can also search for the submit button and use click().

So the only difference is click() has to be done on the submit button and submit() can be done on any form element.

It's up to you.

Solved with quoting all arguments as Andreas suggested.

It looks like it somehow thinks there is a space after -Dwebdriver. Could be an invisible zero-width space. Try typing the command again. Or quote the arguments: java "-Dwebdriver.ie.driver=C:\Users\Administrator\selenium\IEDriverServer.exe" -jar "C:\Users\Administrator\selenium\selenium-server-standalone-3.13.0.jar" -role node -hub "http://localhost:4444/grid/register/" – Andreas

May be you need to use the Actions with name attribute in Xpath. In your XPath use it -

"/*[name()='svg']/*[name()='SVG OBJECT']"  

Then try the following code snippet -

WebElement svgObj = driver.findElement(By.xpath(XPATH));
Actions actionBuilder = new Actions(driver);
actionBuilder.click(svgObj).build().perform();

Attribute validationMessage will return the message, that will be showing if validation fails:

WebElement username = driver.findElement(By.name("uname"));    
String validationMessage = username.getAttribute("validationMessage");

If element has required attribute, browser will show the message after submitting the form:

boolean required = Boolean.parseBoolean(username.getAttribute("required"));

You can check whether entered value is valid:

boolean valid = (Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username);

---

Not: message text and validation is customizable. If you want to test customized validation and message.

Here test code for custom validation(Java, TestNG):

Assert.assertTrue(Boolean.parseBoolean(username.getAttribute("required")), "Username is required and message should be showin");
Assert.assertEquals(username.getAttribute("validationMessage"), "My custom message", "Message text control");

username.sendKeys("@vasya ");
Assert.assertTrue((Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username), "Username has special characters");

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)

Use javascriptExecutor to click the element by embedding javascript. By using javascript executor we can run the javascript on the driver.

WebElement element = driver.findElement(By.id("id-home_prevButton");
((JavascriptExecutor)driver).executeScript("arguments[0].click();", element);

Your questions:

Q 1.) I would like to know why it returns all the texts that following the div?
It should not and I think in will not. It returns all div with 'id' attribute value equal 'containter' (and all children of this). But you are printing the results with ele.getText() Where getText will return all text content of all children of your result.

Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.
Returns:
The innerText of this element.

Q 2.) how should I modify the code so it just return first or first few nodes that follow the parent note
This is not really clear what you are looking for. Example:

<p1> <div/> </p1 <p2/> 

The following to parent of the div is p2. This would be:

 //div[@id='container'][1]/parent::*/following-sibling::* 

or shorter

 //div[@id='container'][1]/../following-sibling::* 

If you are only looking for the first one extent the expression with an "predicate" (e.g [1] - for the first one. or [position() < 4]for the first three)

If your are looking for the first child of the first div:

//div[@id='container'][1]/*[1]

If there is only one div with id an you are looking for the first child:

   //div[@id='container']/*[1]

and so on.
