How to use TracedCommandExecutor class of org.openqa.selenium.remote package

You can try creating a File instance and getting the absolute path from there.

File file = new File("src/test/resources/testData/twt_Pic.jpg");
yourElement.sendKeys(file.getAbsolutePath());

In Java use like this :

System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
         ChromeOptions options = new ChromeOptions();
                options.addArguments("--test-type");
                options.addArguments("--headless");
                options.addArguments("--disable-extensions"); //to disable browser extension popup

                ChromeDriverService driverService = ChromeDriverService.createDefaultService();
                ChromeDriver driver = new ChromeDriver(driverService, options);

                Map<String, Object> commandParams = new HashMap<>();
                commandParams.put("cmd", "Page.setDownloadBehavior");
                Map<String, String> params = new HashMap<>();
                params.put("behavior", "allow");
                params.put("downloadPath", "//home//vaibhav//Desktop");
                commandParams.put("params", params);
                ObjectMapper objectMapper = new ObjectMapper();
                HttpClient httpClient = HttpClientBuilder.create().build();
                String command = objectMapper.writeValueAsString(commandParams);
                String u = driverService.getUrl().toString() + "/session/" + driver.getSessionId() + "/chromium/send_command";
                HttpPost request = new HttpPost(u);
                request.addHeader("content-type", "application/json");
                request.setEntity(new StringEntity(command));
                httpClient.execute(request);
        driver.get("http://www.seleniumhq.org/download/");
        driver.findElement(By.linkText("32 bit Windows IE")).click();

Well, I do need to switch drivers from time to time, so I did this:

I initialize selenium related stuff in my own Class - called by name of the application and the driver is approached by the getters. When calling my class constructor, I use enum type of driver to initialize with:

 private WebDriver driver;
 public TestUI(Environment.DriverToUse drv){
   switch (drv){
        case CHROME:{
            ChromeDriverService service = ChromeDriverService.createDefaultService();
            File file = new File(TestUI.class.getResource("/chromedriver.exe").toURI());
            System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, file.getAbsolutePath());                
            ChromeOptions options = new ChromeOptions();
            options.addArguments("--start-maximized");
            driver = new ChromeDriver(service,options);
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
            break;
        }
        case FIREFOX:{
            FirefoxProfile ffProfile = new FirefoxProfile();
            ffProfile.setPreference("browser.safebrowsing.malware.enabled", false);
            driver = new FirefoxDriver(ffProfile);
            driver.manage().window().setPosition(new Point(0, 0));
            java.awt.Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            Dimension dim = new Dimension((int) screenSize.getWidth(), (int) screenSize.getHeight());
            driver.manage().window().setSize(dim);
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
            break;

        }    

public WebDriver getDriver(){
 return driver;
}

of course my Environment class looks like this

public class Environment {
public enum DriverToUse {FIREFOX, CHROME};
// .. and some other stuff, because I need to test on different environments, so I store here Environment URL for example

And my test class looks something like this

@Before
public static final Environment.DriverToUse USED_DRIVER = Environment.DriverToUse.FIREFOX;

@Test
public void testVersionNumber() throws Exception{

    TestUI testUI= new TestUI(USED_DRIVER);
    WebElement version = testUI.getDriver().findElement(By.id("the Id of element"));
    version.click();
    //...
}

I found a google groups discussion on the topic. These links look like promising alternative to Browsermob:

Chances are this problem is caused by an already-running instance of the Selenium server. The new instance needs to listen on the same port number, but can't, because the port is already in use.

Let's say your Selenium server is configured to start on port 4444. Determine if the port is in use using the 'netstat' command:

On Windows: netstat -an | find "4444"

Expect to see output like this:

  TCP    0.0.0.0:4444           0.0.0.0:0              LISTENING
  TCP    [::]:4444              [::]:0                 LISTENING

On Linux, use: netstat -anp | grep 4444

(No Linux box to hand, so can't show example output!)

If you see any output, you need to kill the process that's listening on the port that Selenium wants to use. On Windows, use netstat -anb to find the process name (it'll be listed after the line specifying the port number). Kill it using the Task Manager. On Linux, the process PID and name will be listed by the command above - kill it using kill <PID>.

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

As a rule of thumb, try to select more elements by one query, if possible. Searching for many elements one-by-one will get seriously slow.

If I understand your needs well, a good way to do this would be using

driver.findElement(By.id("someId::button")).click();
driver.findElement(By.xpath("//*[contains(@id, 'someId--popup::popupItem') " +
    "and text()='" + myDesiredValue + "']"))
    .click();

For more information about XPath, see the spec. It's surprisingly a very good read if you can skip the crap!

That finds and clicks an element with text equal to you desired value which contains "someId--popup::popupItem" in its ID.

List<WebElement> list = driver.findElements(By.xpath("//*[contains(@id, 'someId--popup::popupItem')]"));

That finds all just all elements that contain "someId--popup::popupItem" in their ID. You can then traverse the list and look for your desired element.

Did you know you can call findElement() on a WebElement to search just it's children? - driver.findElement(By.id("someId")).findElements(By.className("clickable"))

Without a peek on the underlying HTML, I guess I can't offer the best approach, but I have some in my head.

As per the documentation Document Object Model (DOM) Level 2 HTML Specification click() method doesn't accepts any parameters, doesn't return any value and doesn't report any exceptions.

So, its clear that we can't override click() method in the first place.

But you can always write a customized user function to click on a WebElement along with certain types of waits. In these cases Selenium's in-built Explicit Wait i.e. the WebDriverWait comes to our help.

ExplicitWait

As per the documentation, an ExplicitWait is a code block you define, configure and implement for the WebDriver instance to wait for a certain condition to be met before proceeding for the next line of code. There are some methods that helps us to implement ExplicitWait that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one of the way ExplicitWait can be achieved.

You can find a detailed discussion on ExplicitWait in this discussion.

You should use a @Factory.

public class SomeTest {

    @Factory
    public Object[] createInstances() {
        Object[] result = new Object[]{            
            new SomeTest(WebDrivers.getChromeDriver())
            // you can add other drivers here
        };
        return result;
    }

    private final WebDriver driver;

    public SomeTest(WebDriver driver) {
        this.driver = driver
    }

    @DataProvider(name = "URLs")
    public Object[][] createData1() {
     return new Object[][] {
       {"url 1"},
       {"url 2"},
       {"url 3"}};
    }    

    @AfterClass
    public void closeWebDriver(){
        driver.quit();
    }   

    //test methods below

    @Test(dataProvider = "URLs")
    public void test1(String url){
        //test 1 with url
    }

    @Test(dataProvider = "URLs")
    public void test2(String url){
        //test 2 with url
    }

    @Test(dataProvider = "URLs")
    public void test3(String url){
        //test 3 with url
    }

    @Test(dataProvider = "URLs")
    public void test4(String url){
        //test 4 with url
    }

}
