How to determine if an element is displayed on screen for specific time using selenium java/python?

There is an webelement(Success or failure message) which gets displayed on screen only for 3 seconds. How can I assure that the element is displayed on screen for 3 seconds using selenium java OR python?

You can use java.time.LocalDateTime and java.time.temporal.ChronoUnit combine with org.openqa.selenium.support.ui.ExpectedConditions.
In this example the time a button is not enabled is measured:
package selenium;
import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class DeviTimeTest {
public static String userDir = System.getProperty("user.dir");
public static String chromedriverPath = userDir + "\\resources\\chromedriver.exe";
public static WebDriver driver;
public static void main(String[] args) {
WebDriver driver = startChromeDriver();
driver.get("https://demoqa.com/dynamic-properties");
LocalDateTime start = LocalDateTime.now();
WebElement button = driver.findElement(By.id("enableAfter"));
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(button));
LocalDateTime finish = LocalDateTime.now();
System.out.println("Button was disabled for " + ChronoUnit.MILLIS.between(start, finish) + " ms.");
driver.quit();
}
public static WebDriver startChromeDriver() {
System.setProperty("webdriver.chrome.driver", chromedriverPath);
ChromeOptions options = new ChromeOptions();
options.addArguments("--ignore-certificate-errors");
options.addArguments("--start-maximized");
options.addArguments("--disable-notifications");
driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
return driver;
}
}
Output:
Starting ChromeDriver 96.0.4664.45 (76e4c1bb2ab4671b8beba3444e61c0f17584b2fc-refs/branch-heads/4664#{#947}) on port 47769

How to resolve this "NET::ERR_CERT_COMMON_NAME_INVALID" exception in Selenium Java?

I'm working on a Java Project using Selenium. I have attempted to implement my test codes. Below here is the snippet of it.
AutoTest
public class AutoTest {
WebDriver driver = null;
#BeforeTest
public void setUp() {
String projectPath = System.getProperty("user.dir");
DesiredCapabilities handlSSLErr = DesiredCapabilities.chrome ();
handlSSLErr.setCapability (CapabilityType.ACCEPT_SSL_CERTS, true);
//Configuration for WebDriver
System.setProperty("webdriver.chrome.driver", projectPath+"/drivers/chromedriver/chromedriver.exe");
driver = new ChromeDriver(handlSSLErr);
}
#Test
public void createTopUpRequest() {
//browse to UAT Server
driver.get("https://10.2.5.215:33000/viewTopUpRequest");
//enter credentials
LoginPage.usernameLogin(driver).sendKeys("ezltest2svc");
LoginPage.passwordLogin(driver).sendKeys("Password123!");
//Click on submit button
LoginPage.loginButton(driver).sendKeys(Keys.RETURN);
}
#AfterTest
public void closeBrowser() {
//driver.close();
}
}
As soon as it tries navigating to this portal: "https://10.2.5.215:33000/viewTopUpRequest", I get the NET::ERR_CERT_COMMON_NAME_INVALID exception. May I know how to bypass the security protocols?

I'm not sure if org.openqa.selenium.remote.DesiredCapabilities even provides such option.
I'm using org.openqa.selenium.chrome.ChromeOptions:
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
public static String userDir = System.getProperty("user.dir");
public static String chromedriverPath = userDir + "\\resources\\chromedriver.exe";
public static WebDriver startChromeDriver() {
System.setProperty("webdriver.chrome.driver", chromedriverPath);
ChromeOptions options = new ChromeOptions();
options.addArguments("--ignore-certificate-errors");
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
return driver;
}
This works as well:
public static WebDriver startChromeDriver() {
System.setProperty("webdriver.chrome.driver", chromedriverPath);
ChromeOptions options = new ChromeOptions();
options.setAcceptInsecureCerts(true);
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
return driver;
}

Selenium cant access a hidden element

breaking my head over the following piece of code in Java, trying to solve a recaptcha for my selenium tests at work before implementing them.
The use case I use: https://www.google.com/recaptcha/api2/demo
WebDriver driver = Selenium.getInstance();
Selenium.goToWebPage("https://www.google.com/recaptcha/api2/demo");
WebDriverWait wait = new WebDriverWait(driver, 5);
List<WebElement> allIFrames = SeleniumUtil.getWebElementNicelyByTagName(driver, wait, "iframe");
if(allIFrames == null){
return;
}
Optional<WebElement> captchaIFrame = allIFrames.stream().filter(webElement -> webElement.getAttribute("src").contains("recaptcha/api2/anchor")).findFirst();
if(!captchaIFrame.isPresent()){
return;
}
WebDriver frame = driver.switchTo().frame(captchaIFrame.get());
//System.out.println(frame.getPageSource());
WebElement recaptchaTokenElement = SeleniumUtil.getWebElementNicelyByXPath(frame, wait, "//*[#type='hidden']");
System.out.println(recaptchaTokenElement);
So with the system.outs i'm trying to find my way to the captcha token, but every time it returns a null element. What the SeleniumUtil so far does is mainly:
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath)));
return driver.findElement(By.xpath(xpath));
And the same for By.CssSelector etc.
I am already in the right IFrame, because the page source is printen out correctly, but searching by #recaptcha-token (cssselector), recaptcha-token (id), //*#id="recaptcha-token" does not work.
Maybe someone can help me with this?

There is a iFrame where the driver needs to be switched to.
After few tries I've got:
standard chromedriver setup:
package selenium;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
public class WebDriverSetup {
public static String userDir = System.getProperty("user.dir");
public static String chromedriverPath = userDir + "\\resources\\chromedriver.exe";
public static WebDriver driver;
public static WebDriver startChromeDriver() {
System.setProperty("webdriver.chrome.driver", chromedriverPath);
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
driver = new ChromeDriver(options);
driver.manage().window().maximize();
return driver;
}
}
And getting the token:
package selenium;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class GoogleRecaptchaDemo extends WebDriverSetup {
public static void main(String[] args) {
WebDriver driver = startChromeDriver();
driver.get("https://www.google.com/recaptcha/api2/demo");
List<WebElement> frames = driver.findElements(By.tagName("iframe"));
driver.switchTo().frame(frames.get(0));
WebElement rc = driver.findElement(By.id("recaptcha-anchor-label"));
rc.click();
WebElement recaptchaToken = driver.findElement(By.id("recaptcha-token"));
String token = recaptchaToken.getAttribute("value");
System.out.println(token);
driver.quit();
}
}
My output, last line is the token:
Starting ChromeDriver 86.0.4240.22 (398b0743353ff36fb1b82468f63a3a93b4e2e89e-refs/branch-heads/4240#{#378}) on port 25872

Selenium - Webdriver executable doesnot exist error

I am getting below error while trying to execute my selenium code shown below:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Demo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "‪C:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("www.google.com");
}
}
Error - Exception in thread "main" java.lang.IllegalStateException:

at Demo.main(Demo.java:11)
I have placed the chrome driver in the location mentioned and the version is also double checked.

This is very minor change with static mode, try with :
static WebDriver driver;
static String driverpath = "C:\\chromedriver.exe";
public static void main(String [] args)
{
System.setProperty("webdriver.chrome.driver", driverpath);
driver = new ChromeDriver();
}
As we are executing Java static main method, its requires to handle driver with Static variables.

Error in fire fox selenium web driver

Recently, bump into this issues with selenium firefox driver.
Thanks in advance
Set UP
os.name: 'Mac OS X',
os.arch: 'x86_64',
os.version: '10.12.6',
java.version: '1.8.0_131'
Firefox version 56.0.1 (64-bit)

I tried different ways to tackle it but always come with the same error.
1. update all the selenium test driver to the latest
2. specify the directory export PATH = $PATH driverDir

Your problem is here:
#After
public void test_Cleaning(){
System.out.println("Closing Browser");
baseURL = null;
driver.close();
driver.quit();
}
Try only with close().
Explanation here.

We generally get this , if we use driver.close() and driver.quit() together so it would be better if you remove driver.close();
public void test_Cleaning(){
System.out.println("Closing Browser");
baseURL = null;
driver.quit();
}
