Presentation: "Automated Web Application Testing with Selenium"

Track: Solution Track 1

Time: Wednesday 13:00 - 14:00

Location: Wordsworth Room

Abstract:

Selenium is a test tool that allows you to write automated web application tests in many programming languages. The test use any mainstream browser with JavaScript support and can target arbitrary websites.

This talk starts with a quick demo of creating automated tests using the Selenium IDE and then show how these tests can be integrated with existing Java, C#, or Ruby test suites. We'll end with a discussion on how to write robust tests, and how to structure tests to make them more reusable.

Tutorial: "Test-Driven Development"

Track: Tutorial

Time: Monday 13:00 - 16:00

Location: To be announced

Abstract:

This tutorial demonstrates the development of a small example application using test-driven development and related technologies. The system will comprise a handful of Java classes that exemplify typical components found in enterprise applications, including domain objects and a service layer. The tutorial is structured into three 'iterations' which cover

state-based testing with JUnit
interaction-based testing with JUnit and jMock
deployment in lightweight containers such as PicoContainer and Spring.

The iterations not only introduce the concepts but also provide room for the discussion of trade-offs and edge cases, e.g. how to deal with testing private methods and when not to use dynamic mocks but fake objects.

Attendees gain an understanding of how proper use of test-driven development fosters good design; through decoupling and interface discovery for example. Attendees will also gather a nice catalogue of the most commonly used patterns used in conjunction with test-driven development.
