Automate Web user interface tests Verify functionality in different browsers on different platforms Check periodically to see if the site is on-line and works correctly Why should you care?
Javascript functional test runner Started by Jason Huggins, Paul Gross and Jie Tina Wang, in 2004. Opensource product Actively developed and maintained by Thoughtworks Download from OpenQA.org Selenium in a nut-shell
Lots of different commands to manipulate DOM elements and verify text, DOM or timing Locate elements by name, id, xpath... Tests are described as tables Selenese – the language of Selenium
Selenium - Core http://selenium.openqa.org/
Selenium - IDE • Firefox extension • Record-replay • Command reference • save/export/load tests http://selenium-ide.openqa.org
Selenium-RC • Automate Selenium tests from Java/.NET/Ruby etc • Execute in multiple browsers, on remote machines • Integrate into wider business tests and CI tools http://selenium-rc.openqa.org
Selenium Grid • Run tests on multiple machines in parallel • Solves the biggest problem with Selenium, speed • Supports EC2 http://selenium-grid.openqa.org
CubicTest • Visual test management • Eclipse-based • Mocking up web sites based on test scripts http://www.cubictest.com
StoryTestIQ • Wiki-based • Mashup of Selenium and FitNesse • Run SQL commands • Integrate with CI tools http://storytestiq.solutionsiq.com/
WebTest fixtures • FitNesse fixtures for Selenium • User-friendly language or direct selenium RC access • Integrate Selenium in your business tests http://www.fitnesse.info/webtest
Domain specific testing language Agile 2008 presentation from Solutions IQ
What's good? • Relatively easy to automate web UI tests • Record/Replay for regression tests • RC allows integration with CI and JUnit/FitNesse tests
What's bad? • Speed: RC->Browser communication is a speed bottleneck (run in grid, overnight) • UI is brittle, tests depending on the UI break a lot (DSTL might fix this, page abstractions as well) • Data-backed tests are not easily repeatable (integrate with DB test engines)
Best practices • Use Selenium to verify workflow and session • Don't use it to check business rules • Don't put Selenium tests in your main development build – run them overnight • Have dedicated machines that run tests • DON'T THINK OF THIS AS A REPLACEMENT FOR EXPLORATORY TESTING!!!
Although selenium is an essential trace element, it is toxic if taken in excess. Wikipedia on chemical element Selenium
