Key Properties
BusinessI Software as a Service.I Integration is a Key Part.
Core PlatformI Legacy => JEE Based, Started Over 12 Years Ago.I CCO => Based on Microservices.
ProductI Legacy => Running on JBoss AS.
Quality Story
Long Story in Short
I No Automated Unit Testing from Inception.I Automation Varied on Product Level.I Existing Automation Tools Old/Not Reliable.I Several Automation Attempts Ended with Failure.I Long QA Cycles / More Slip Through.I Story Continues ....

Time Line
I Started 2013 Q2.I Started for One Critical Product with 0% Automation.I Extensive Support Given by Top Management.I Identify Potential as a Common Framework.I Roll-out Carried with Help of Product QA Teams.I Currently Using 5 eBuilder Products.
In the Start
ConsiderationsI End User.I Acceptable Time Limit.I Many Types of Tests.
DecisionsI End User => Testers in Scrum Teams.I Semi Technical Language Suitable for Testers.I Stories Independent from Each Other.I Developing a Framework for All Domains in eBuilder.I Support Atlassian Bamboo CI Server.
