How to use SlowLoadableComponent class of org.openqa.selenium.support.ui package

You can easily accomplish this task with CSS.

The formula is:

element[attribute='attribute-value']

So if you have,

<a href="mysite.com"></a>

You can find it using:

By.cssSelector("a[href='mysite.com']");

this works using any attribute possible.

This page here gives good information on how to formulate effective css selectors, and matching their attributes: http://ddavison.io/css/2014/02/18/effective-css-selectors.html

Try calling createSession before calling clearBrowserCache.

Using your setup, this works:

chromeDriver.getDevTools().createSession();
chromeDriver.getDevTools().send(Network.clearBrowserCache())

and this produces java.util.concurrent.TimeoutException:

chromeDriver.getDevTools().send(Network.clearBrowserCache())

You can verify that the browser cache has been cleared with this snippet:

    ChromeDriver driver = new ChromeDriver();
    driver.get("https://refreshyourcache.com/en/cache-test/");
    Thread.sleep(2000);
    driver.getDevTools().createSession();
    driver.getDevTools().send(Network.clearBrowserCache());
    driver.get("https://refreshyourcache.com/en/cache-test/");
    Thread.sleep(5000);

If you run the code, the pages displayed in the test browser will show these images:

If you commment out the line driver.getDevTools().send(Network.clearBrowserCache()); then you get a different result:

Selenium 1.x does not support XPath 2.0. Hence you cannot use XPath 2.0 methods like matches(), replace() etc..

You might want to consider XPath 1.0 methods like contains(), starts-with() etc.

Also, to achieve your goal you can try

//tr[starts-with(@id,'data-row-') and translate(@id,'0123456789','')]

The stacktrace you shared is not the stacktrace, but I think the testng log.
The example you provided actually works. I just made the test fail, because in the @AfterMethod a screenshot is taken only if the test fails: if(!result.isSuccess())
Then when I ran the example again, I got:
java.io.FileNotFoundException: C:\screenshot2.png (Access is denied)
Then I changed the location of the picture to be on D: where the permissions are correct, and it worked end to end, I can see the screenshot.

Cheers

public class TestFile {

    WebDriver driver = new FirefoxDriver();

    @Test
    public void Testone() {

        driver.get("http://www.google.com/");
        assert false;

    }

    @AfterMethod(alwaysRun = true)
    public void catchExceptions(ITestResult result) {
        System.out.println("result" + result);
        String methodName = result.getName();
        System.out.println(methodName);

        if (!result.isSuccess()) {

            try {

                File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
                FileUtils.copyFile(scrFile, new File("C:\\screenshot2.png"));
            } catch (IOException e1) {
                e1.printStackTrace();
            }

        }
    }
}

Finally I found an answer that works with Firefox as well as Google Chrome.

WebElement we = this.driver.findElement(By.id("size-btn"));

JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript("arguments[0].click();", we);

waitForElementPresent(By.xpath("//div[@id='size-btn' and contains(@class,'opened')]/span"));

  <input attr1='a' attr2='b' attr3='c'>foo</input>

getAttribute(attr1) you get 'a'

getAttribute(attr2) you get 'b'

getAttribute(attr3) you get 'c'

getText() with no parameter you can only get 'foo'

You must execute JS to set the window.alert call to do nothing. You can use this method.

static void confirmDialog(WebDriver driver) {
    if (driver instanceof PhantomJSDriver) {
        PhantomJSDriver phantom = (PhantomJSDriver) driver;
        phantom.executeScript("window.alert = function(){}");
        phantom.executeScript("window.confirm = function(){return true;}");
    } else driver.switchTo().alert().accept();
}

You have to give your chromeDriver.exe file path instead of taking the path from the URL.

example:

 System.setProperty("webdriver.chrome.driver",
            "C:\\Downloads\\chromedriver.exe");

First: capabilities you were trying to use are for IOS only

On Android you have to find popup via findElement and close them yourself.

Second: since you start Appium session for web application, before searching for native popups you must switch the context:

    String webContext = driver.getContext();
    Set<String> contexts = driver.getContextHandles();
    for (String context: contexts){
        if (context.contains("NATIVE_APP")){
            driver.context(context);
            break;
        }
    }
    driver.findElement(By.id("android:id/button1")).click();

Don't forget to switch context back to web to continue:

    driver.context(webContext);
