How to use getDimension method of org.openqa.selenium.Rectangle class

Since chromedriver 75.0.3770.8 CapabilityType.LOGGING_PREFS is deprecated. Use goog:loggingPrefs instead.

You can either use the crx file of the extension or point to a directory it's installed in. Assuming you have it installed, you'll need to add ChromeOptions to your new ChromeDriver:

ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=/path/to/extension");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);

See here for more details and walkthrough.

EDIT: to see your extensions path, navigate to chrome://version and look at 'Profile Path'. In that folder look for 'Extensions' folder. The extension ID for AdBlock Plus is cfhdojbkjhnklbpkdaibdccddilifddb. So the path/to/extension should be something like (Windows):

C:\Users\<user>\AppData\Local\Google\Chrome\User Data\<profile>\Extensions\cfhdojbkjhnklbpkdaibdccddilifddb

Use:

String actualString = driver.findElement(By.xpath("xpath")).getText();
assertTrue(actualString.contains("specific text"));

You can also use the following approach, using assertEquals:

String s = "PREFIXspecific text";
assertEquals("specific text", s.substring(s.length()-"specific text".length()));

to ignore the unwanted prefix from the string.

As I told the question is in implementation of JUnit.

You can see that:

Parallelized extends Parametrized extends Suite extends ParentRunner

on the other hand:

ConcurrentTestRunner extends BlockJUnit4ClassRunner extends ParentRunner

hence they are from different hierarchies of inheritance.

And now what you have to look at is implementation of the:

org.junit.runners.ParentRunner#getChildren

method. For the org.junit.runners.BlockJUnit4ClassRunner it is:

protected List<FrameworkMethod> computeTestMethods() {
    return getTestClass().getAnnotatedMethods(Test.class);
}

which generates all methods with annotations. But for org.junit.runners.Parameterized it is:

for (int i= 0; i < parametersList.size(); i++)
  runners.add(newtestClassRunnerForParameters(getTestClass().getJavaClass(),
                parametersList, i));

And the last one gives only classes.

Proposal: override your Parallelized class with definition of org.junit.runners.ParentRunner#getChildren from BlockJUnit4ClassRunner.

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();

The answer is to implement an ElementLocatorFactory that allows you to provide a search context (meaning, a driver or a WebElement).

public class SearchContextElementLocatorFactory
        implements ElementLocatorFactory {

    private final SearchContext context;

    public SearchContextElementLocatorFactory(SearchContext context) {
        this.context = context;
    }

    @Override
    public ElementLocator createLocator(Field field) {
        return new DefaultElementLocator(context, field);
    }
}

Then, when instantiating your page object, use this locator factory.

WebElement parent = driver.findElement(By.xpath("//div[contains(@class,'yui3-accordion-panel-content') and child::div[.='Sidebar']]"));
SearchContextElementLocatorFactory elementLocatorFactory = new SearchContextElementLocatorFactory(parent);
PageFactory.initElements(elementLocatorFactory, this);

Now your @FindBy annotations will be relative to parent. For example, to get the main sidebar WebElement:

@FindBy(xpath = ".")
WebElement sideBar;

I solved my problem by visiting developer option to my mobile and enabled the security setting of my device It was not a coding problem. I have changed setting in my mobile phone. Setting -->Additional setting -->Developer option -->(USB Debugging Security setting). For reference Image attached.enter image description here

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".

Even though I'm somewhat late answering the question:

You can now use WebElement.isDisplayed() to check if an element is visible.

Note:

There are many reasons why an element could be invisible. Selenium tries cover most of them, but there are edge cases where it does not work as expected.

For example, isDisplayed() does return false if an element has display: none or opacity: 0, but at least in my test, it does not reliably detect if an element is covered by another due to CSS positioning.
