Test Automation - Principles and Practices
This document discusses principles and practices for test automation. It covers topics like different levels of testing from unit to integration to UI, the importance of testing non-functional requirements, using a test pyramid approach with more unit and component tests than UI tests. It also discusses practices like continuous integration, test automation framework design considerations, sample framework architectures, and page object patterns. The overall goal is to provide guidance on building quality into software through effective test automation practices.

CONTINUOUS INTEGRATION (CI) ”…is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible…." - Martin Fowler, ThoughtWorks Chief Scientist Ø http://www.thoughtworks.com/continuous-integration
