This course provides a brief introduction to the concept of testing Service Oriented Architecture (SOA) based applications. SOA testing introduces new challenges. This course starts with an overview of SOA fundamentals and then looks into what is involved in testing SOA applications. The course also looks into some of the popular SOA testing tools in the market and demonstrates features of one such tool (selected by customer) and provides hands-on exercises to re-enforce learning.
Course Objectives:
Highlight foundational SOA concepts
Gain a realistic understanding of the various challenges and unique considerations that SOA brings into play for testing and quality assurance
Learn how to apply unit testing, integration testing, and customer acceptance testing to a service oriented enterprise
Explore the various types of artifacts introduced by SOA (WSDL, BPEL, SOAP, etc.) and the implications they have for testing
Gain hands-on experience using a SOA testing tool to test both services and business processes
Course Prerequisites
No specialized technical pre-requisites are required for this course; however a basic understanding of SOA and some knowledge in IT systems and distributed computing is expected.
Who Should Attend?
Quality assurance, application developers, and enterprise architects will all gain considerable value from this curriculum.
