1. xpath - bracket [] and @

Use square brackets to further concentrate the search
The @ symbol facilitates working with attributes.

//book[@type=”hardback”]

The first book element is read from the XML document using the following XPath:
/books/book[1]

xpath - double slash (//)

A double slash (//) signals that all elements in the XML document that match the search criteria are returned, regardless of location/level within the document.

Use a double slash for location-agnostic element matching

xpath - single slash (/)

The slash (/) separates child nodes
Search for specific nestings anywhere in a document

The following XPath statement returns all book elements:

//books/book

<?xml version="1.0" encoding="ISO-8859-1"?>
<books>
<book type=”hardback”>
<title>Atlas Shrugged</title>
<author>Ayn Rand</author>
<isbn>0525934189</isbn>
</book>
<book type=”paperback”>
<title>A Burnt-Out Case</title>
<author>Graham Greene</author>
<isbn>0140185399</isbn>
</book>
</books>

xpath - contains

By.xpath("//a[contains(@href, 'login')]")

tell webdriver to wait

WebDriverWait wait = new WebDriverWait(_driver, TimeSpan.FromSeconds(4));

WebElement autocomplete = wait.Until(x => x.FindElement(By.ClassName("xyz")))

http://deanhume.com/Home/BlogPost/selenium-webdriver---wait-for-an-element-to-load/64

dropdown -- Use the Select class

Select select = new Select(driver.findElement(By.tagName("select")));
select.deselectAll();
select.selectByVisibleText("2008");

submit() with form

Instead of "driver.findElement(By.id("submit")).click();",

you can use a simpler form "element.submit();"

navigate().to, forward(), back()

driver.navigate().to("http://www.example.com");

driver.navigate().forward();

driver.navigate().back();

delete cookie

// By name

driver.manage().deleteCookieNamed("CookieName");

// By Cookie

driver.manage().deleteCookie(loadedCookie);

// Or all of them

driver.manage().deleteAllCookies();

show cookie

// And now output all the available cookies for the current URL

Set<Cookie> allCookies = driver.manage().getCookies();

for (Cookie loadedCookie : allCookies) {

System.out.println(String.format("%s -> %s", loadedCookie.getName(), loadedCookie.getValue()));

}

setting cookie

// Now set the cookie. This one's valid for the entire domain

Cookie cookie = new Cookie("key", "value");

driver.manage().addCookie(cookie);

JavascriptExecutor

WebElement element = (WebElement) ((JavascriptExecutor)driver).executeScript("return $('.cheese')[0]");

List<WebElement> labels = driver.findElements(By.tagName("label"));

List<WebElement> inputs = (List<WebElement>) ((JavascriptExecutor)driver).executeScript(

"var labels = arguments[0], inputs = []; for (var i=0; i < labels.length; i++){" +

"inputs.push(document.getElementById(labels[i].getAttribute('for'))); } return inputs;", labels);

CSS

Target HTML

<div id="food"><span class="dairy">milk</span><span class="dairy aged">cheese</span></div>

CSS expression

WebElement cheese = driver.findElement(By.cssSelector("#food span.dairy.aged"));

WebDriverWait & ExpectedCondition

import org.openqa.selenium.support.ui.WebDriverWait;

10 means time out after 10 seconds.

(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {

public Boolean apply(WebDriver d) {

return d.getTitle().toLowerCase().startsWith("cheese!");

}

});

xpath - case insensitive or sensitive

Good example of page objects

http://thomassundberg.wordpress.com/2011/10/18/testing-a-web-application-with-selenium-2/#more-615

Some page object examples here:
https://github.com/Ardesco/Ebselen/tree/master/ebselen-tests/src/test/java/c
om/lazerycode/ebselen/pagefactory/google
Used by the tests here:
https://github.com/Ardesco/Ebselen/tree/master/ebselen-tests/src/test/java/c
om/lazerycode/ebselen/website/google
Very simplistic but should hopefully be a decent pointer.

wait for a condition

WebDriverWait myWait = new WebDriverWait(webDriver, 45);

ExpectedCondition<Boolean> conditionToCheck = new ExpectedCondition<Boolean>() {

@Override

public Boolean apply(WebDriver input) {

return (input.findElements(By.id("fContent").size() > 0);

}

};

myWait.until(conditionToCheck);

page object - structure

create two packages

package AAA contains some test classes
(Import class BBB)

package BBB contains some Page Object classes

page object - rules

- Page objects themselves should never be make verifications or assertions.

-There is one, single, verification which can, and should, be within the page object and that is to verify that the page, and possibly critical elements on the page, were loaded correctly.

page object -- code

/**

* Page Object encapsulates the Sign-in page.

public class SignInPage {

private Selenium selenium;

public SignInPage(Selenium selenium) {

this.selenium = selenium;

if(!selenium.getTitle().equals("Sign in page")) {

throw new IllegalStateException("This is not sign in page, current page is: " +selenium.getLocation());

}

/**

* Login as valid user

* @param userName

* @param password

* @return HomePage object

public HomePage loginValidUser(String userName, String password) {

selenium.type("usernamefield", userName);

selenium.type("passwordfield", password);

selenium.click("sign-in");

selenium.waitForPageToLoad("waitPeriod");

return new HomePage(selenium);

}

------------------------------------------------

/**

* Page Object encapsulates the Home Page

public class HomePage {

private Selenium selenium;

public HomePage(Selenium selenium) {

if (!selenium.getTitle().equals("Home Page of logged in user")) {

throw new IllegalStateException("This is not Home Page of logged in user, current page" + "is: " +selenium.getLocation());

}

public HomePage manageProfile() {

// Page encapsulation to manage profile functionality

return new HomePage(selenium);

}

/*More methods offering the services represented by Home Page

of Logged User. These methods in turn might return more Page Objects

for example click on Compose mail button could return ComposeMail class object*/

}

---------------------------------------------------

/***

* Tests login feature

public class TestLogin {

public void testLogin() {

SignInPage signInPage = new SignInPage(selenium);

HomePage homePage = signInPage.loginValidUser("userName", "password");

Assert.assertTrue(selenium.isElementPresent("compose button"),"Login was unsuccessful");

}

xpath to find the links under the footer area

The footer section HTML is : <div id = "footer"> ....... </div>

driver.findElements(By.xpath("//div[@id='footer']/descendant::a"));

xpath for dynamically changing element

* Target html is //html/body/div/div[2]
* div[2] changes to div[3] or div[4] etc dynamically

Xpath -- driver.findElements(By.xpath("//html/body/div/")).findElement(By.tagName("div"));

how to execute Javascript

Target element:
<input type="email" placeholder="Email" value="" style="display:
block;" name="emailAccountID" id="emailAccountID">

How to execute Javascript:
((JavascriptExecutor) driver).executeScript(@"this.browserbot.getUserWindow().document.getElementById("emailAccountID").style.visibility="visible";");

useful selenium docs

http://code.google.com/p/selenium/w/list

Changing user agent on FF

FirefoxProfile profile = new FirefoxProfile();

profile.setPreference("general.useragent.override", "some UA string");

WebDriver driver = new FirefoxDriver(profile);
