Automated Web Testing Using Selenium
Download as ppt, pdf2 likes4,903 views
The document discusses Selenium, an open-source tool for automating web application testing. It provides an overview of Selenium components and how they work. It also discusses challenges with the traditional Selenium approach and how Tellurium addresses these challenges by defining the UI structure separately from tests using a Groovy DSL. This allows for easier refactoring and separation of UI and test code compared to the traditional "record and play" Selenium approach. The document concludes with best practices for test automation and references for further information.

- 18. Problems in Selenium Verbose Locators everywhere Coupling UI locators, actions, and assertions are coupled Not expressive What does the UI look like? Speed Since IE is lack of native XPath support, so tests run in IE are very slow Record and Play Re-labeling a button or moving it to another part of the window may require the test to be re-recorded Refactor Seems to be difficult Reusable Less likely

- 20. What is Tellurium? UI module based web testing framework built on top of Selenium UI is defined in Groovy class and tests can be written in Java (JUnit 4 or TestNG) Groovy Pure DSL script Handles the mapping from Java object to UI Reference: http:// code.google.com/p/aost /
- 21. What challenges are addressed in Tellurium No longer “record and play” style, but UI module oriented Separated Robust Easy to refactor
- 22. What challenges are addressed in Tellurium Support jQuery Selector useJQuerySelector() disableJQuerySelector()
- 23. Summarization: Advantage/Disadvantage Involved new language Very new, some potential risks we don’t know No longer “record and play” style, but UI module oriented Easy to refactor Easy to use UI and tests are separated Faster performance in IE Ideally only defining the HTML elements is required as the entry criteria of scripting Tellurium Hard to refactor Very slow in IE UI locators, actions, and assertions are coupled Record and Play requires little or no software development It’s required to have both the HTML and the back-end code ready before we start scripting Selenium Disadvantage Advantage Pre-condition
- 24. Best Practices To Automate or Not to Automate? That is the Question! The test framework should be approved, documented, reviewed. Structure scripts with minimal dependencies. Test automation is a fulltime effort, not a sideline. A dedicated team is required.

- #22: XPath builder can build the XPath from the composite locator, i.e., a set of attributes. Starting with version 0.6.0, Tellurium supports jQuery selectors to address the problem of poor performance of XPath in Internet Explorer. jQuery selector builders are used to automatically generate jQuery selectors instead of XPath with the following advantages: Faster performance in IE. Leverage the power of jQuery to retrieve bulk data from the web by testing with one method call. New features provided by jQuery attribute selectors.
