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

A JavaScript based

Open Source

Web testing tool

That supports testing Web 2.0 applications

On multiple browsers

And multiple Operating Systems

Quick Demo

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

Using Selenium Bot mode: Selenium Core HTML Tables Driven mode: Selenium Remote Control (RC) Test cases in language of choice Record mode: Selenium IDE

Architecture

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

No programming required

Doesn't scale – duplication is a major issue.

Driver approach better for 'Real' test suites

Can develop tests in language of choice:

C#, Java, Ruby, Python, Perl

Easier data management via DB / Excel

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

Test code is just like production code!

Needs refactoring, abstraction

API for the application

Can build tests from API building blocks

Try to maintain meaning – in test names, variable names, comments, and suite organization

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

Do your test suites break as the app evolves?

The importance of DRY: Don't Repeat Yourself

Minimize changes to test suite as app changes

Avoid redoing / reworking entire test suites

Avoiding duplication simpler for test code: test steps execute sequentially

Methods, parametrization

To some extent, Object Orientation

Demo: Refactoring Tests

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