How to use usingTechnologyPreview method of org.openqa.selenium.safari.SafariDriverService.Builder class

Make it executable: In CentOs use chmod +x chromedriver

A few quick searches led me to this:

http://blogs.steeplesoft.com/posts/2012/grabbing-screenshots-of-failed-selenium-tests.html

Basically, he recommends creating a JUnit4 Rule that wraps the test Statement in a try/catch block in which he calls:

imageFileOutputStream.write(
    ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES));

Does that work for your problem?

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.

There is a page documenting Advanced User Interactions; which has a lot of great examples on how to generate a sequence of actions, you can find it here

// Configure the action
Actions builder = new Actions(driver);

builder.keyDown(Keys.CONTROL)
   .click(someElement)
   .click(someOtherElement)
   .keyUp(Keys.CONTROL);

// Then get the action:
Action selectMultiple = builder.build();

// And execute it:
selectMultiple.perform();   

or

Actions builder = new Actions(driver);

Action dragAndDrop = builder.clickAndHold(someElement)
   .moveToElement(otherElement)
   .release(otherElement)
   .build();

dragAndDrop.perform();

Use the reflected method to get the group of the test as below :

@BeforeMethod
public void befMet(Method m){
        Test t = m.getAnnotation(Test.class);
        System.out.println(t.groups()[0]);//or however you want to use it.
}

PhantomJS by default starts with no local-storage; see this discussion.

To enable local-storage via Selenium I have used the following Java code. Sorry, it has been too long since I have used C#, but I am confident the C# bindings have similar methods available.

DesiredCapabilities capabilities = DesiredCapabilities.phantomjs();
// Phantom options can only be set from CLI
List<String> cliArgs = new ArrayList<String>();
cliArgs.add("--local-storage-quota=5000");
Path local_storage_path = Files.createTempDirectory("PhantomLocalStorage-");
cliArgs.add("--local-storage-path=" + local_storage_path.toString());
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgs);
WebDriver driver = new PhantomJSDriver(capabilities);

Note that local_storage_path will not be deleted after you are done with it. If you need that, you can set up a hook as per this post. But I suspect in C# this part is going to be wildly different from Java.

What is happening here is the creation of an anonymous class that inherits from ExpectedCondition. In the body of this class he is then overriding the method apply(...).

In a word, no. It's not possible using the Selenium WebDriver API. This has been discussed ad nauseam in the issue tracker for the project, and the feature will not be added to the API.

tldr; Not by default, no. You cannot extract a By from a previously found WebElement. It is possible, however, through a custom solution.

It's possible to implement a custom solution, but Selenium does not offer this out-of-the-box.

Consider the following, on "why"..

By by = By.id("someId");
WebElement e = driver.findElement(by);

you already have the By object, so you wouldn't need to call something like e.getBy()
