SeleniumYou can’t be good at everything
How Selenium Remote Control works You launch a server on your test machine. Your tests connect to that server via IP. The server launches a browser, with selenium
CORE embedded as javascript into the page. Selenium CORE simulates user actions with
javascript.
The GoodThe Good The BadThe Bad
Doesn’t steal your mouse/keyboard.
Works with any browser that uses javascript
Works for any OS that supports java.
Very fast page interactions.
Large API Supports a variety of
programming languages. Can be run on remote
machines
• Can’t see anything outside the page object.
• Not all browsers support all functionality.
• Some pages aren’t automatable.
• Can’t see inside third party apps
• XSS Limitations
The javascript sandbox
WebDriver Introduction
A different way of automating the browser. Create a browser-specific driver to control the
browser directly. Have to do this for each browser!
Object oriented API Doesn’t need a real browser No javascript limitations No need for a server. Isn’t as delicate as selenium.
Selenium 2
Went into Beta Dec 24th. WebDriver + Selenium
The two projects have merged (literally) into Selenium 2.0
Large browser support and no javascript limitations. No server The old API’s are still available. New API’s are becoming available.
Automating with Selenium 2
You have 2 options: IWebDriver
This is just the WebDriver api Doesn’t support a lot of browsers. Will need to change all your tests.
WebDriverBackedSelenium Uses the old Selenium 1 API But uses WebDriver to run things if possible Can use selenium 1 if the browser isn’t supported.
The WebDriver API
Object Oriented Doesn’t break nearly as often
Handles pageloads automatically Fewer problems automating
Somewhat more complicated API selenium.type(“password”,”thisIsMyPassword”); driver.findElement(By.id("password")).sendKeys(“thisIs
MyPassword"); By.Id, By.Xpath, By.Name, By.ClassName, By.PartialLinkText
All the supported browsers work really well Can extend the API to add custom functionality. Works well with a Page Object design model.
Page Object Design Pattern
Adds a layer of abstraction into your code. Helps to organize your code once it grows large. All automation is automatically reusable and shareable. A way to separate tests from re-usable functions. A way to store information about how the system works. A way to specify what page functions start on, and what page
they end on. A way to programmatically break your tests when
functionality changes. Makes code maintenance easier. There is even a PageFactory class available to automatically
create them.
How does it work?
Each page is defined as it’s own class. Actions (including navigation) are represented as functions for a class. Each function returns a new Page object, signifying what page the
actions stops on. Your tests “know” what page you are on, and will only give you access
to functions available to that class. Tests only talk to the page objects. Page objects only talk to the driver. Elements on the page are stored as variables for the page object. Automatic page validations can be stored in the constructor for each
page object. Tests become a string of well defined functions, not meaningless
gibberish. Tests can be grouped by namespace. Class Inheritance can be used to define functionality to a set of pages. We can make functional logic transparent to the tests by returning
different inherited classes.
Bad Tests
globalVars.logDescription = "log in"; globalVars.selenium.Open(globalVars.mobiUrl); functions.type("userId", globalVars.studName + "1"); functions.type("password", globalVars.studPass + "1"); functions.clickAndWait("signInBtn"); selenium.click("//a[@id='discussions']/span"); selenium.click("//a[@id='thingsToKnow']/span"); globalVars.logDescription = "Checking elements on happenings:by date page";
selenium.waitForElementNotVisible("//div[@id='THSContainer']//span[@class='ajaxLoadingHeader']");
selenium.waitForElementVisible("//div[@id='THSContainer']/ul[1]/li[1]"); selenium.click("//div[@id='THSContainer']//span[@class='replytext']"); selenium.click("backButton"); selenium.waitForElementVisible("//div[@id='TTHContainer']/ul[1]/li[1]"); selenium.click("//div[@id='TTHContainer']//span[@class='replytext']"); selenium.click("backButton"); globalVars.selenium.Select("byDateFilter", "label=Things Happening Soon"); selenium.waitForElementVisible("//div[@id='THSContainer']/ul[1]/li[1]"); selenium.click("//div[@id='THSContainer']//span[@class='replytext']"); selenium.click("backButton"); globalVars.selenium.Select("byDateFilter", "label=Things That Happened");
Better Tests
[Test]
public void testByDateTab() {
funtions.loginMobi(); selenium.click("//a[@id='discussions']/span"); selenium.click("//a[@id='thingsToKnow']/span"); functions.verifyThingsToKnow();
functions.verifyThingsHappeningSoon(); selenium.Select("byDateFilter", "label=Things That
Happened"); functions.verifyThingsThatHappened();
}
Good Tests
[Test] public void testByDateTab() {
selenium.Open(Moby_Common.MobyLoginUrl); LoginPage loginPage = new LoginPage(selenium); HappeningsPage happeningsPage =
loginPage.loginAs(Common.stud1Name, Common.stud1Password); happeningsPage.waitToLoad(); Assert.That(!happeningsPage.isByTypePageLoaded()); Assert.That(happeningsPage.isByDatePageLoaded()); Assert.That(!happeningsPage.isByCoursePageLoaded()); happeningsPage.filterResults("byDateFilter","Things That Happened"); Assert.That(happeningsPage.isVisible("TTHContainer")); happeningsPage.filterResults("byDateFilter", "Things Happening Soon"); Assert.That(happeningsPage.isVisible("THSContainer")); happeningsPage.filterResults("byDateFilter", "All Types"); Assert.That(happeningsPage.isVisible("TTHContainer")); Assert.That(happeningsPage.isVisible("THSContainer")); }
The Page Object:
public class HappeningsPage : WebPageBaseClass
{ private string _loadingImage =
"//span[@class='ajaxLoadingHeader']"; private string _moreLink = "more";
public HappeningsPage(ISelenium selenium) { this.selenium = selenium; this.title = "Happenings"; this.url = "index.html"; assertPageLoadedCorrectly(); }
public HappeningsPage waitToLoad() {
waitForElementNotVisible(_loadingImage ); return new HappeningsPage(selenium); }
public ContentItemPage goToItem(string type, string name)
{ click("//div[@id='" + type +
"']//span[text()=\"" + name + "\"]"); return new
ContentItemPage(selenium); } public HappeningsPage
clickMoreLink() { click(_moreLink); return new
HappeningsPage(selenium); } public HappeningsPage
filterResults(string id, string name) { selectDropdown(id, name); return new
HappeningsPage(selenium); }}
