using implictilyWait with Webdriver - selenium

lib- selenium-java2.0rc2.jar and selenium-server-standalone-2.-b3.jar
simple test:
webDriver = new FirefoxDriver();
webDriver.get("http://www.google.com");
webDriver.findElement(By.name("q")).sendKeys("Test");
webDriver.findElement(By.name("btnG")).click();
Assert.assertTrue(webDriver.findElement(By.cssSelector("ol#rso>li:nth-child(1) a"))
.getText().equalsIgnoreCase("Test.com Web Based Testing and Certification Software v2.0"));
Assertion fails, and then I added BAD wait statement, just before asserition -
Thread.sleep(3000);
Assert.assertTrue(webDriver.findElement(By.cssSelector("ol#rso>li:nth-child(1) a"))
.getText().equalsIgnoreCase("Test.com Web Based Testing and Certification Software v2.0"));
Test succeeds.
But then came across implicitlyWait and used it as -
webDriver = new FirefoxDriver();
webDriver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
webDriver.get("http://www.google.com");
webDriver.findElement(By.name("q")).sendKeys("Test");
webDriver.findElement(By.name("btnG")).click();
Assert.assertTrue(webDriver.findElement(By.cssSelector("ol#rso>li:nth-child(1) a"))
.getText().equalsIgnoreCase("Test.com Web Based Testing and Certification Software v2.0"));
Assertion again fails, looks like implicitlyWait() does not have any impact here. And I definitely don't want to use Thread.sleep(). What could be the possible solution?

You can use webdriverwait class to wait for an expected condition to come true.
ExpectedCondition e = new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
//Wait until text changes
return webDriver.findElement(By.cssSelector("ol#rso>li:nth-child(1) a"))
.getText().equalsIgnoreCase("Test.com Web Based Testing and Certification Software v2.0"));
}
};
Wait w = new WebDriverWait(driver, 60);
w.until(e);
//do asserts now
Assert.assertTrue(...);

How to understand if credentials are valid or not using selenium

I created an app that lets users login through my app to Wikipedia, and I achieved this goal with selenium, but I can't find a way to verify either credentials are ok or not.
I tried find by id but since failed condition doesn't display an ID it's not helping.
private void button1_Click(object sender, EventArgs e)
{
string BaseUrl = "https://en.wikipedia.org/w/index.php?title=Special:UserLogin&returnto=Main+Page";
int TimeOut = 30;
var driver = new FirefoxDriver();
driver.Navigate().GoToUrl(BaseUrl);
var loginBox = driver.FindElement(By.Id("wpName1"));
loginBox.SendKeys("email.address#gmail.com");
var pwBox = driver.FindElement(By.Id("wpPassword1"));
pwBox.SendKeys("!SuperSecretpassw0rd");
I would like to know if entered credentials are correct or not.
A general approach to this kind of question is to ask yourself, "How can a human see this?" and then replicate this behavior in your test. In your example, how would a human detect that the login is wrong?
A human would see the error message.
Selenium on the other hand only sees the DOM tree. So for Selenium to see the error message, you need to find out where to look in the DOM tree. To do this, open your browser developer tools and find the matching section in the DOM tree:
With this in mind, a very simple solution is to find the error div that is shown when the credentials are invalid.
var error = driver.findElement(By.className("error"));
Then you can check if the element actually exists and you can use additional Selenium methods to inspect the actual contents of the error message, to see what the error is. If the field is not present then you could assume that the login succeeded. In addition you can use driver.getCurrentUrl() to inspect whether you are still located on the login page, to confirm that you are really logged in.
That being said, if you try to do any serious browser testing you should consider using the page object model (see https://www.toolsqa.com/selenium-webdriver/page-object-model/) so you don't end up with an unmaintainable mess of test cases.
As you havn't mentioned the language binding this solution is based on Java.
An elegant approach to validate whether the credentials are valid or not would be to induce a try-catch{} block to look for the element with the error inducing WebDriverWait for the desired visibilityOfElementLocated() and you can use the following Locator Strategies:
Code Block:
public class A_demo
{
public static void main(String[] args) throws Exception
{
System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get("https://en.wikipedia.org/w/index.php?title=Special:UserLogin&returnto=Main+Page");
new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input[name='wpName']"))).sendKeys("Helios.Lucifer#stackoverflow.com");
driver.findElement(By.cssSelector("input[name='wpPassword']")).sendKeys("!SuperSecretpassw0rd");
driver.findElement(By.cssSelector("button#wpLoginAttempt")).click();
try
{
new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("form[name='userlogin']>div.error>p")));
System.out.println("Unsuccessful login attempt");
}
catch (TimeoutException e)
{
System.out.println("Successful Login.");
}
driver.quit();
}
}
Console Output;
Unsuccessful login attempt

What's the difference between ImplicitlyWait and RetryingElementLocator regarding PageObject?

When I use PageObject and I want to set a time to wait for elements on the page then I use ImplicitlyWait:
Driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(3));
This means that when my page object is initializing:
PageFactory.InitElements(Driver, this);
Then it will wait for elements not less then 3 seconds.
Also there is another feature of Selenium that I discovered recently: RetryingElementLocator class
Code of this class: https://seleniumhq.github.io/selenium/docs/api/dotnet/html/T_OpenQA_Selenium_Support_PageObjects_RetryingElementLocator.htm
As I understand it allows to set time to wait elements on a page for PageObject.
The example of usage is the next:
IWebDriver driver = new ChromeDriver();
RetryingElementLocator retry = new RetryingElementLocator(driver, TimeSpan.FromSeconds(5));
IPageObjectMemberDecorator decor = new DefaultPageObjectMemberDecorator();
PageFactory.InitElements(retry.SearchContext, this, decor);
So the question is: if there is any difference between 2 methods and if so when it's better to use the second one?

How to set focus to a web element in Selenium webdriver

I am new to Selenium. I am learning by automating some test scenarios on MakeMyTrip website.
Scenario: Editing the user account created.
Code:(yet to be completed)
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys("abcd#gmail.com");
driver.findElement(By.id("password_text")).sendKeys("*****");
driver.findElement(By.id("login_btn")).click();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.findElement(By.id("ssologinlink")).click(); **======> Here I notice the click is not happening to select the My Account or My Profile from the drop down.**
}
}
Kindly let me know how I can take the focus back to the webelement once I login.
driver.findElement(By.id("ssologinlink")).click();
works fine the first time but not post the user login.
Thank you for your comments. The element ID had not changed post the login. I had to wait for the user name to appear before I click on the drop down.
Below is the code which worked for me:
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys(""abcd#gmail.com"");
driver.findElement(By.id("password_text")).sendKeys("*******!");
driver.findElement(By.id("login_btn")).click();
WebElement myDynamicElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[#id='ssologinlink']/strong[contains(text(),'user')]")));
myDynamicElement.click();
}
}
Try waiting for the element to be clickable with Expected Conditions of Explicit waits. See the doc here
public class AccountEdit {
#Test
public void AccEdit()
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.makemytrip.com/");
driver.manage().window().maximize();
driver.findElement(By.id("ssologinlink")).click();
driver.findElement(By.id("username")).sendKeys("abcd#gmail.com");
driver.findElement(By.id("password_text")).sendKeys("*****");
driver.findElement(By.id("login_btn")).click();
//Waiting for the element to be clickable with Explicit wait
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.elementToBeClickable(By.id("ssologinlink")));
myDynamicElement.click();
}
}
Some time element ID gets changed post login(something like dynamic ID).. pls. check the element ID again and update..

Using Selenium, is it possible to create a mock WebElement to use in a unit test?

Using Selenium, is it possible to create a virtual WebElement to use in a unit test?
#Test
public void testIt() {
JavascriptExecutor js = (JavascriptExecutor) driver;
WebElement we = (WebElement)js.executeScript("code to create and return a input element");
assertTrue("default value", we.getText());
}
I thought about using a Spy or Mock object, but WebElement doesn't have any "setter" methods and so once I create a WebElement instance, I don't know how I would give it values.
For example, would it be possible to convert a HtmlUnit web element to a Selenium WebElement (that contains attributes)?
final String html = "<html><head></head><body id='tag'><b>text</b></body></html>";
final HtmlPage page = loadPage(html);
final HtmlUnitWebElement node = page.getHtmlElementById("tag");
WebElement we = node.findElement(By.xpath(".//b"));
You can write a proxy class with own implementation. I dont know about Java Selenium, but .Net Selenium has proxy WebDriver that used by PageObjectFactory and this proxy WebDriver returns proxy WebElement class that works in lazy way - it does initialization on the first access to that object.
This may help you as example - https://github.com/SeleniumHQ/selenium/tree/master/java/client/src/org/openqa/selenium/support/events . You can check EventFiringWebDriver that works like a proxy too and creates proxy EventFiringWebElement object.
So you can write own implementation for WebElement that will have setters and you can use them with test data.

how would I run Selenium test through the GRID using C#

i have just set-up the selenium grid on my local machine and everything seems to be up and running.
my question is, is there a way I can run the test case from selenium grid node (command prompt)?
I am using WebDriver for creating my testcase using .Net
Sample code from here
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
// Requires reference to WebDriver.Support.dll
using OpenQA.Selenium.Support.UI;
class GoogleSuggest
{
static void Main(string[] args)
{
// Create a new instance of the Firefox driver.
// Notice that the remainder of the code relies on the interface,
// not the implementation.
// Further note that other drivers (InternetExplorerDriver,
// ChromeDriver, etc.) will require further configuration
// before this example will work. See the wiki pages for the
// individual drivers at http://code.google.com/p/selenium/wiki
// for further information.
WebDriver driver = new RemoteWebDriver(new Uri("http://127.0.0.1:4444/wd/hub"),
DesiredCapabilities.FirefoxDriver());
//Notice navigation is slightly different than the Java version
//This is because 'get' is a keyword in C#
driver.Navigate().GoToUrl("http://www.google.com/");
// Find the text input element by its name
IWebElement query = driver.FindElement(By.Name("q"));
// Enter something to search for
query.SendKeys("Cheese");
// Now submit the form. WebDriver will find the form for us from the element
query.Submit();
// Google's search is rendered dynamically with JavaScript.
// Wait for the page to load, timeout after 10 seconds
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
wait.Until((d) => { return d.Title.ToLower().StartsWith("cheese"); });
// Should see: "Cheese - Google Search"
System.Console.WriteLine("Page title is: " + driver.Title);
//Close the browser
driver.Quit();
}
}
WebDriver driver = new RemoteWebDriver(new Uri("http://127.0.0.1:4444/wd/hub"),
DesiredCapabilities.FirefoxDriver());
OR in c#
IWebDriver driver;
DesiredCapabilities capability = new DesiredCapabilities();
driver = new RemoteWebDriver(
new Uri("http://hub-cloud.com/wd/hub/"), capability);
driver.Navigate().GoToUrl("http://www.google.com");
