Automation Overhaul for a Banking Platform

​

Overview

• Re-architecting a vast automation suite for a credit-card banking application, to reduce its execution time and to be able to run it without any manual intervention.

• Tech Stack – Java, Jenkins, Rest-Assured, Selenium, Cucumber, Oracle, DB2, H2

​

Business Challenge

• Automation suite being brittle - took a long time to complete execution with frequent manual interventions, with the result of needing over 2 weeks to complete “selective” regression.

• The dependency of automation suite on many external services and databases, added to its complexity.

​

Solution Offered

• Focused efforts around service virtualization and stubbing responses.

• Studied structure and composition of DB schemas exhaustively, to efficiently create in-memory databases stubs.

• Refactored automation BDD scripts to be more business centric, and less technical and elaborative step definitions.

• Stressed on frequent execution of scripts on CI servers, with greater discipline to keep them green.

​

Business Benefits

• Squeezed regression execution time to less than a week, with multiple modules being fully automated.

• Greater knowledge of external system interactions and composition of DB schemas.
