Starting with:
For example, if the ID of an element is ctrl_12,
this will locate and return elements with ctrl at
the beginning of the ID.
input[id$='_userName']
Ending with:
For example, if the ID for an element is a_1_
userName, this will locate and return elements
with _userName at the end of the ID.
input[id*='userName']
Containing:
For example, if the ID of an element is panel_
login_userName_textfield, this will use
the userName part in the middle to match and
locate the element.

- 27. overview • walkthrough of the key webdriver api • commands www.time2test.co.uk !27 www.seleniumbootcamp.com
- 28. API - must know Webdriver - control the browser • Webdriver driver = new FirefoxDriver(); WebElement - work with elements on the page • WebElement myElement = driver.findElement(By.id(“id”)) it’s an interface to a browser www.time2test.co.uk !28 www.seleniumbootcamp.com

- 35. overview • use firebug/chrome developer tools to help with locating webElements • cssSelectors • XPATHS • id • name www.time2test.co.uk !35 www.seleniumbootcamp.com
- 36. xpaths v cssSelectors • Try to use cssSelectors over XPATHS • your automation scripts will run faster • use XPATHs to save time • finding elements on a page is an art! www.time2test.co.uk !36 www.seleniumbootcamp.com
- 37. xpaths • This notation // for xpaths • follow the trainer’s examples • use a tool to help determine xpaths www.time2test.co.uk !37 www.seleniumbootcamp.com
- 38. xpaths - firepath • great tool to assist with xpath determination • use with firebug on firefox www.time2test.co.uk !38 www.seleniumbootcamp.com
- 39. css selectors • reference sheet • http://www.w3schools.com/cssref/ css_selectors.asp • Too much to learn in one day • With time, you will become a master www.time2test.co.uk !39 www.seleniumbootcamp.com
- 40. css selectors 2 • partial match on attribute values ^= $= *= www.time2test.co.uk input[id^=‘ctrl’] Starting with: For example, if the ID of an element is ctrl_12, this will locate and return elements with ctrl at the beginning of the ID. input[id$='_userName'] Ending with: For example, if the ID for an element is a_1_ userName, this will locate and return elements with _userName at the end of the ID. input[id*='userName'] Containing: For example, if the ID of an element is panel_ login_userName_textfield, this will use the userName part in the middle to match and locate the element. !40 www.seleniumbootcamp.com
- 41. css selector gadget • chrome tool extension • Search in google for “CSS Selector Tester” ! www.time2test.co.uk !41 www.seleniumbootcamp.com
- 42. dynamic elements Does the ID of your element dynamically change? <p id="bootcamp_dynamic_1234">This p tag has a dynamic id</p> ! xpath notation to find the p tag on the page "//p[contains(@id,'bootcamp_dynamic_')]" ! cssSelector notation to find the p tag on the page "p[id*='bootcamp_dynamic_']" www.time2test.co.uk !42 www.seleniumbootcamp.com
- 44. overview • what is jUnit? • what is Hamcrest? • how do we use it? www.time2test.co.uk !44 www.seleniumbootcamp.com
- 46. jUnit • Pick up the style used in our examples and then apply them www.time2test.co.uk !46 www.seleniumbootcamp.com
- 47. hamcrest • Hamcrest is a framework for writing matcher objects allowing 'match' rules to be defined declaratively • introduces matchers and is more friendly to read • use instead of the junit assertions • http://edgibbs.com/junit-4-with-hamcrest/ www.time2test.co.uk !47 www.seleniumbootcamp.com
- 48. hamcrest usage • A good starting place is the assertThat() method that can now almost always be used in place of the traditional assertEquals(). • assertThat() can be found in org.junit.Assert, but it defines using Hamcrest matchers in the signature: static <T> void assertThat(T actual, org.hamcrest.Matcher<T> matcher) www.time2test.co.uk !48 www.seleniumbootcamp.com
- 50. test Structure • good style • void setUp() • void tearDown() • all tests should finish with an assertion • element locators should be defined in a separate class - think about constants www.time2test.co.uk !50 www.seleniumbootcamp.com
- 52. overview • how to handle alerts? • how to handle cookies? www.time2test.co.uk !52 www.seleniumbootcamp.com
- 54. cookies Set<Cookie> cookies=driver.manage().getCookies(); for(Cookie cookie:cookies) { System.out.println(cookie.getName()+" "+cookie.getValue()); } //To find the number of cookies used by this site System.out.println("Number of cookies in this site "+cookies.size()); www.time2test.co.uk !54 www.seleniumbootcamp.com
- 56. overview • Locating elements on a page is already an art. • Locating elements on a page that don’t always appear in a timely manner is also an art. • Implicit vs Explicit Waits • Explicit waits using ExpectedConditions • Explicit waits using custom expected conditions • fluent waits www.time2test.co.uk !56 www.seleniumbootcamp.com
- 57. Implicit waits ! Just wait for a period to time //Set the Implicit Wait time Out to 10 Seconds driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); www.time2test.co.uk !57 www.seleniumbootcamp.com
- 58. Explicit waits Wait until a condition is met WebDriverWait wait = new WebDriverWait(driver, 10); wait.until(ExpectedConditions.titleContains("sele nium")); www.time2test.co.uk !58 www.seleniumbootcamp.com
- 59. Fluent Waits • ! Use the code that is best for your application under test // Waiting 30 seconds for an element to be present on the page, checking // for its presence once every 5 seconds. Wait<WebDriver> wait = new FluentWait<WebDriver>(driver) .withTimeout(30, SECONDS) .pollingEvery(5, SECONDS) .ignoring(NoSuchElementException.class); ! WebElement foo = wait.until(new Function<WebDriver, WebElement>() { public WebElement apply(WebDriver driver) { return driver.findElement(By.id("foo")); } }); www.time2test.co.uk !59 www.seleniumbootcamp.com
- 60. page objects !60
- 61. overview • what are page objects? • how to use page objects? www.time2test.co.uk !61 www.seleniumbootcamp.com
- 62. what are page objects? • popular design pattern • object orientated class for a page • interface to the web page • methods for elements • encapsulates features represented by the page www.time2test.co.uk !62 www.seleniumbootcamp.com
- 63. benefits of page objects? • more readable code • logical grouping • easy to maintain code • tests don’t change if UI changes - just that page object • clean separation between test code and page specific code www.time2test.co.uk !63 www.seleniumbootcamp.com
- 66. overview • running your tests on Firefox • running your tests on IE • running your tests on Chrome • running remotely - selenium grid www.time2test.co.uk !66 www.seleniumbootcamp.com
- 67. RemoteWebDriver • WebDriver driver = new RemoteWebDriver(new URL(“http://server-with-selenium-grid-running: 4444/wd/ hub"), DesiredCapabilities.firefox()); • This example assumes that Selenium Server is running on server-with-selenium-grid-running with the default port of 4444. • You can run Selenium Server on any machine • For example, I run the test code from my Mac OS X computer but I run Selenium Server on a Window XP machine. www.time2test.co.uk !67 www.seleniumbootcamp.com
- 68. cross browser • different browsers behave differently • perform most testing on Firefox • some subset test execution on different browsers www.time2test.co.uk !68 www.seleniumbootcamp.com
