Unable to find a link while running Selenium Test case - selenium-webdriver

I am using Selenium webdriver. I can log in to the application, but while logging out it gets stuck, reason it cannot find logout link. I tried to find it byLink and byId. I have also tried using thread.sleep() but nothing seems to be working.
Logout link is present in all the pages.
HTML code:
<li>#{loginView.loggedInUser}>
<ul><li><h:link value="Administration" outcome="Administration.xhtml" /></li>
<li><h:commandLink value="Logout" actionListener="#{loginView.logout}">
<f:param id="userName" value="#{loginView.username}" />
</h:commandLink></li>
</ul></li>
SELENIUM code:
Thread.sleep(5000);
WebElement logOut = findElementByLinkText("Logout");
logOut.click();
assertEquals("Please sign in: ", findElementBySelector("h3.loginTitle.centerAlign").getText());

Use this code check how many links are present on page if it contains your logout link then you can click on it by using locator "linktext".
public void Link(){
driver.get(baseUrl);
HtmlTagFinder links = LinkFinder.links();
List<WebElement> allLinks = (List<WebElement>) links.findFrom(driver);
System.out.println(allLinks.size());
int i = 1;
for(WebElement link : allLinks){
System.out.println(i);
System.out.println(link.getText());
i++;
}
driver.close();
driver.quit();
}

driver.findElement(By.xpath("#value='Logout'")).click();

Why can't Selenium Web Driver find the elements in this case?

Selenium newbie here. The examples I tried so far worked well but now I stumbled upon a case that seemingly doesn't work:
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class GeckoDriverTest
{
public static void main(String[] args) throws Throwable
{
System.setProperty("webdriver.gecko.driver", "D://XXX/seleniumdrivers/geckodriver.exe");
FirefoxDriver driver=new FirefoxDriver();
driver.manage().window().maximize();
driver.get("https://www.aerzen.com/de/karriere/stellenangebote.html");
System.out.println("URL = "+driver.getCurrentUrl());
Thread.sleep(3000);
driver.findElement(By.cssSelector("a.consent-banner--accept.button.submit")).click();
Thread.sleep(3000);
System.out.println("URL = "+driver.getCurrentUrl());
List<WebElement> elements = driver.findElements(By.cssSelector("tr > td > a"));
System.out.println("Elements: "+elements.size());
for(WebElement element : elements)
{
String url = element.getAttribute("href");
System.out.println(url);
}
}
}
The first part does work but the "tr > td > a" selector doesn't find any elements although I'm pretty sure they exist (I can see them in the browser window).
Any idea what's going wrong there? Thanks a lot.
The table is inside an iframe. In order to access these elements you will need to switch to that iframe.
Also instead of tr > td > a cssSelector try using table td.real_table_col1 a cssSelector.
This should work better:
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//iframe")));
driver.switchTo().frame(driver.findElement(By.xpath("//iframe")));
List<WebElement> elements = driver.findElements(By.cssSelector("table td.real_table_col1 a"));
System.out.println("Elements: "+elements.size());
for(WebElement element : elements)
{
String url = element.getAttribute("href");
System.out.println(url);
}
Also instead of hardcoded pauses like
Thread.sleep(3000);
You should use ExpectedConditions something like
WebdriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("a.consent-banner--accept.button.submit")));

Unable to click on a button (Angular JS application)

I'm unable to click on a button (Application built on Angular Js). My automation framework is existing one built on Java/Selenium WebDriver. I have tried with Xpath, CSS, etc still not working.
<button type="button" id="Button2" class="btn btn-primary btn-xs" data-ng-click="StartWizard()" data-ng-keyup="$event.keyCode == 13 ? StartWizard() : null">Import New File</button>
Script:
WebElement clickNextButton = driver.findElement(By.xpath("//button[contains(text(),'Import New File')]"));
clickNextButton.click();
Error:
Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//button[contains(text(),'Import New File')]"}
Could you please help me to resolve this. Please let me know if this can be resolved using ngWebDriver?
You can execute the ng-click function defined in the element:
String waitForAngularJs = "angular.element(\"#Button2\").scope().StartWizard();";
try {
ExpectedCondition<Boolean> waitForAngular = new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver driver) {
return ((JavascriptExecutor) driver).executeAsyncScript(waitForAngularJs).equals(true);
}
};
WebDriverWait wait = new WebDriverWait(myWebDriver, 60);
wait.until(waitForAngular);
}catch(Exception e) {
e.printStackTrace();
}
Enjoy the code!

Clicking button in Vaadin application has no effect with Selenium WebDriver

I'd like to interact with a Vaadin application (Vaadin 8) using WebDriver. The login form is wrapped using the PageObject pattern.
#Test
public void login() {
driver.get("http://localhost:8080/intern/login");
LoginPage loginPage = new LoginPage(driver);
loginPage.enterUserCredentials("test", "test");
loginPage.submit();
}
The submit() method finds the login button and triggers a .click().
#FindBy(id = "loginButton")
private WebElement loginButton;
public void submit() {
this.loginButton.click();
}
When using the "real" application the click triggers several requests and responses to/from the server until the next page after the login page is loaded.
In the above WebDriver example however nothing happens after the click although I instructed the driver to do an implicit wait.
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Authentication Window Alert is working in IE11 but not working in Chrome v60

In my scenario, when I launch a URL, an authentication alert window opens up and I need to enter Username and Password from excel and on clicking on 'Log In' it'll show me the web homepage. I've implemented this using the below code snippet and it's working perfectly in IE11. But when I'm trying to run the same code in Chrome v60, it's not working. It's showing the authentication alert window but not performing any action on it. Screenshot attached. Can anyone suggest please.
Selenium WD version - 3.4.0
Code:
public static void loadApplicationURL(WebDriver driver) throws Exception
{
String SSPathl = null;
String URL = Generic_Functions.GetParameterFromInputSheet("URL");
try
{
driver.get(URL);
Thread.sleep(6000);
LoginApplication.isAlertPresent(driver);
}
}
public static boolean isAlertPresent(WebDriver driver) {
try {
driver.switchTo().alert();
UserAndPassword UP = new UserAndPassword(UserName,Password);
driver.switchTo().alert().authenticateUsing(UP);
Thread.sleep(8000);
return true;
}
catch (Exception e) {
return false;
}
}
For test browsers, have created a separate class. Find below the snippet used for IE and Chrome browsers.
For Chrome
System.setProperty("webdriver.chrome.driver",".\\Resources\\chromedriver.exe");
driver = new ChromeDriver()
In case of IE,
[System.setProperty("webdriver.ie.driver",".\\Resources\\IEDriverServer.exe");
DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer();
ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);
ieCapabilities.setCapability("nativeEvents", true);
driver = new InternetExplorerDriver(ieCapabilities);][1]

Not able to Click a Link in Gmail using Selenium Webdriver

I am a learner.
I am trying to automate the logout functionality of Gmail using Selenium Webdriver but unable to do so ..
There are two Phases in logout, first click the Right Link at the top, if that box appears then click logout. iam unable to do so.
<span id="gbi4t" style="max-width: 76px; text-align: left;">Mahmood Ali</span>
<a id="gb_71" class="gbqfbb" href="?logout&hl=en&hlor" onclick="gbar.logger.il(9,{l:'o'})" role="button" target="_top">Sign out</a>
here is my xpath
//*[#id="gbi4t"] -> Clicking that top to get the logout pop up
//*[#id="gb_71"] -> To logout the gmail application
i have tried such as
driver.findElement(By.id("gbi4t")).click(); OR
driver.findElement(By.xpath("//*[#id='gbi4t']")).click();
driver.findElement(By.id("gb_71")).click(); OR
driver.findElement(By.xpath("//*[#id='gb_71']")).click();
Some ideas out there ?
Actually the <span> isn't recognized as an element.
You need to use the <a id="gbg4" ...> to click() on it, wait the pop up and click on the <a id="gb_71" class="gbqfbb" ...> to logout.
I let you code, since you need to pracctice :P
tell me what's up.
Suggestions :
What i can suggest to you is to use the cssSelector().
why ? Because it's faster than the xpath and when page like google or others use dynamic value used for id/name it's better to use the class attribute and cssSelector() is way better than others.
But sometimes you'll use xpath to find an element that has "cancel" as inner text (exemple : <a>cancel</a> )
cssSelector() reference
You can also try following:
driver.find_element(:id, "gbgs4dn").click
driver.find_element(:id, "gb_71").click
This worked for me.
This code certainly works for me:
// (after logging to google.com)
WebDriverWait wait = new WebDriverWait(driver, timeoutInSeconds);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("gbi4t")));
//open overlay
driver.findElement(By.id("gbi4t")).click();
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("gb_71")));
//press logout
driver.findElement(By.id("gb_71")).click();
Heres a solved example ::
package testme;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class testexample {
public static WebDriver driver;
public static WebElement element;
public static void main(String args[]) throws InterruptedException {
//setting the chrome driver
System.setProperty("webdriver.chrome.driver", "C:/Users/workspace/Downloads/chromedriver.exe");
driver = new ChromeDriver();
driver.get("http://www.gmail.com");
element =driver.findElement(By.linkText("Sign in"));
element.click();
Thread.sleep(1000);
element = driver.findElement(By.id("Email"));
element.sendKeys("yourusername#gmail.com");
element = driver.findElement(By.id("Passwd"));
element.sendKeys("yourpassword");
element.submit();
Thread.sleep(1000);
//click on the logout link step 1
element = driver.findElement(By.xpath("//*[#id='gb']/div[1]/div[1]/div/div[3]/div[1]/a"));
element.click();
// click on actual logout button step 2
element = driver.findElement(By.id("gb_71"));
element.click();
//closing the webdriver window after successful completion of the test
driver.close();
}
}
