What is Selenium? <ul><ul><li>A JavaScript based </li></ul></ul><ul><ul><li>Open Source </li></ul></ul><ul><ul><li>Web testing tool </li></ul></ul><ul><ul><li>That supports testing Web 2.0 applications </li></ul></ul><ul><ul><li>On multiple browsers </li></ul></ul><ul><ul><li>And multiple Operating Systems </li></ul></ul>

Quick Demo

5.
Overview <ul><ul><li>History: originated from TW Time Sheet application </li></ul></ul><ul><ul><li>Extremely popular Open Source Web testing tool </li></ul></ul><ul><ul><li>Can be used for Acceptance / Functional testing </li></ul></ul><ul><ul><li>Can be used for reproducing bugs </li></ul></ul>

6.
Using Selenium <ul><ul><li>Bot mode: Selenium Core </li></ul></ul><ul><ul><ul><li>HTML Tables </li></ul></ul></ul><ul><ul><li>Driven mode: Selenium Remote Control (RC) </li></ul></ul><ul><ul><ul><li>Test cases in language of choice </li></ul></ul></ul><ul><ul><li>Record mode: Selenium IDE </li></ul></ul>

Architecture

8.
Table or driver based? <ul><ul><li>Table based approach fine for simple tests. </li></ul></ul><ul><ul><ul><li>No programming required </li></ul></ul></ul><ul><ul><ul><li>Doesn't scale – duplication is a major issue. </li></ul></ul></ul><ul><ul><li>Driver approach better for 'Real' test suites </li></ul></ul><ul><ul><ul><li>Can develop tests in language of choice: </li></ul></ul></ul><ul><ul><ul><li>C#, Java, Ruby, Python, Perl </li></ul></ul></ul><ul><ul><ul><li>Easier data management via DB / Excel </li></ul></ul></ul>

9.
Maintaining Test Suites <ul><ul><li>Test code is just like production code! </li></ul></ul><ul><ul><li>Needs refactoring, abstraction </li></ul></ul><ul><ul><li>API for the application </li></ul></ul><ul><ul><li>Can build tests from API building blocks </li></ul></ul><ul><ul><li>Try to maintain meaning – in test names, variable names, comments, and suite organization </li></ul></ul>

10.
Evolving Test Suites <ul><ul><li>Do your test suites break as the app evolves? </li></ul></ul><ul><ul><li>The importance of DRY: Don't Repeat Yourself </li></ul></ul><ul><ul><li>Minimize changes to test suite as app changes </li></ul></ul><ul><ul><li>Avoid redoing / reworking entire test suites </li></ul></ul><ul><ul><li>Avoiding duplication simpler for test code: test steps execute sequentially </li></ul></ul><ul><ul><li>Methods, parametrization </li></ul></ul><ul><ul><li>To some extent, Object Orientation </li></ul></ul>

Demo: Refactoring Tests

12.
Ajax support <ul><ul><li>Selenium supports testing Web 2.0 applications </li></ul></ul><ul><ul><li>Monitor the DOM for completion of Async calls </li></ul></ul><ul><ul><li>waitForCondition() </li></ul></ul><ul><ul><li>waitForValue() </li></ul></ul>

13.
Continuous Integration <ul><ul><li>Run Selenium tests as part of the build </li></ul></ul><ul><ul><ul><li>Works with both Core and Driven modes </li></ul></ul></ul><ul><ul><ul><li>(Each time a developer checks in, if necessary) </li></ul></ul></ul><ul><ul><li>Can generate HTML reports, published to entire team </li></ul></ul><ul><ul><li>Helps catch bugs ASAP </li></ul></ul><ul><ul><ul><li>Addresses risk of catching bugs late in the cycle </li></ul></ul></ul>

14.
Limitations <ul><ul><li>Most limitations valid if using Selenium Core: </li></ul></ul><ul><ul><ul><li>Alerts </li></ul></ul></ul><ul><ul><ul><li>“ Same Origin Policy” </li></ul></ul></ul><ul><ul><ul><li>File uploads </li></ul></ul></ul>

15.
Summary <ul><ul><li>Selenium is a testing framework for Web Applications </li></ul></ul><ul><ul><li>Drivers allow web testing in language of choice </li></ul></ul><ul><ul><li>Test scripts are code: need maintenance, refactoring </li></ul></ul><ul><ul><li>Limitations of Selenium </li></ul></ul>
