AGENDAComing up next Selenium & friends Page objects Locators Implicit & explicit waits Building your tests Running your testsTHERE WILL BE CODE!!! 4. W H Y A U T O M AT E ?Regression testing sucks 5. SELENIUM AND FRIENDSThe world it lives in WebDriver API (Java / Ruby / Python / C#) Test FrameworksJava (jUnit, TestNG)Ruby (Test::Unit, MiniTest, Rspec, Cucumber)Python (py.test)C# (nUnit) Build Tools (Ant, Maven, Gradle, Rake .... ) Continuous Integration Server (Jenkins, Bamboo, Cruise Control) Browsers (IE, FF, Chrome, Mobile .... ) Application Under Test 6. A W ORD ABOUT SELENIUM IDEUse with caution 7. R E C O R D & P L AY B A C K ( I S ) F O R D U M M I E SA shortcut to brittle, flaky tests 8.

PA G E O B J E C T SUsage guidelines The public methods represent the services that the page offers Try not to expose the internals of the page Generally dont make assertions Methods return other Page Objects Need not represent an entire page Different results for the same action are modelled as different methodshttp://code.google.com/p/selenium/wiki/PageObjects 10.

L O C AT O R SWhy I prefer By object locatorsBy locators allow for nested lookups 17. FIREFINDER PLUGIN FOR FIREFOXA tool for testing CSS & xPath locators 18. WAIT CONDITIONSTiming is everythingImplicit Waits+ Quick to implement+ Covers most scenarios- Slows down tests- Cannot use to wait for absence of Web Elements 19. WAIT CONDITIONSTiming is everythingExplicit Waits 20. WAIT CONDITIONSExplicit Waits+ Most efficient use of waits+ Built in ExpectedConditions class covers majority of scenarios+ Custom wait conditions can be added to cover any other scenario- Need to be manually added to each Page Object methodhttp://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/support/ui/ExpectedConditions.html 21. WAIT CONDITIONSUsage Guidelines Avoid static pauses Use long timeouts Add explicit waits to end of page object action methods Always leave your Web Application in known ready state 22. BUILDING THE TESTSLessons learnt so farKeep tests focusedDont share test dataDo test data tear down at the start of each testPlan to run in parallel from day 1 23.
