Introduction to Selenium
- 1. Selenium Web Test Automation Tool Rohit Nayak Talentica Software
- 2. Agenda Demo What is Selenium? Why? Pros/Cons Writing test cases using Selenium Architecture Best Practices
- 3. Demo Record a test in Selenium IDE Review test in Selenese HTML
- 4. Similar Tools Bad Boy Sahi Silk Test, QTP (paid) Grinder Others: Watir, OpenSTA
- 5. What is Selenium? Test tool for web applications Actually runs in a browser Supports tests in many languages Selenese (pure HTML, no backend required) Java, C#, Perl, Python, Ruby Record/playback (Firefox plugin: Selenium IDE) Open Source with corporate backing Lives at selenium.org
- 6. Advantages Free! Can test across multiple browsers Mimics actual user experience Ajax / CSS support Use language of choice Large user community Great tools: CubicTest, Grid, HRMES
- 7. Common Problems in Web Testing Record/replay is not reusable, is fragile Managing test cases UI Changes make tests brittle
- 8. Problems Performance (~HTMLUnit, WebTest) Reporting (~WebTest) Fancy CSS/Ajax needs tricky coding Data dependency should be avoided
- 9. Best Practices All tests should be source control One test per function not per page Nightly runs Separate environ specific variables Automate fixed function, others manual Abstract out functionality and reuse them Parameterize your tests Framework!!
- 10. Code for testability Demand this from Development Visible feedback on actions (hidden values in case div appears/disappears) (dev-only) url for database teardown Use of IDs for important UI elements Good HTML Good logs
- 11. Demo 2 Show same test written in Java Show same test written in PHP
- 12. Java Example public void testGoogleTestSearch() throws Exception { selenium.open("http://www.google.com/webhp"); assertEquals("Google", selenium.getTitle()); selenium.type("q", "Selenium OpenQA"); selenium.click("btnG"); selenium.waitForPageToLoad("5000"); assertEquals("Selenium OpenQA - Google Search", selenium.getTitle()); }
- 13. JUnit public void setUp() throws Exception { selenium = new DefaultSelenium( "localhost", 4444, "*chrome", "http://www.google.com"); selenium.start(); } public void tearDown() throws Exception { selenium.stop(); }
- 14. Some Selenese Commands submit type isTextPresent createCookie isElementPresent fireEvent dragdrop open goBack Input mouseOver storeText assertSelected keyPress getTitle isVisible waitForCondition click
- 15. Element locators ID: id=foo Name: name=foo First ID, then name: identifier=foo DOM: document.forms[‘myform’].myDropdown XPath: xpath=//table[@id='table1']//tr[4]/td[2] Link Text: link=sometext Sensible defaults, e.g. xpath if starts with //
