A Structured Approach to
Enterprise Test Automation
Venkatesh Kovvuri
Head of Innovation & Automation Practice
Overview
»
With increase in the complexity of application software and enterprise infrastructure, the
quality guidelines & standards have also mounted. Effective testing of such apps can’t be
assured by manual testing alone. By reducing human intervention during test processes
and automating them can result in an effective and efficient methodology to meet those
standards.
»
A Structured Approach will provide opportunity to deal with complex application software
and enterprise infrastructure.
•
Extends the usage of automation to entire software testing lifecycle in addition to conventional automated test
execution (design, data, tasks, infra etc)
•
Addresses challenges around selection, prioritization and execution of automation projects in large enterprises
•
Encompasses all key components essential for executing complex automation projects
•
Provides an asset ‘toolkit’ for Test Automation - Process, Technology, Integration and Quality
•
Supports integration with industry leading open source and commercial software testing tools
•
Provides visibility into the aspects of Quality Governance on the application portfolio

Enterprise Test Automation
Business Challenges
Challenge
Description
Candidate
Selection/Prioritization
Enterprise IT stack contains a large number (dozens to hundreds
to thousands) of applications and often pose the difficulty to
select and prioritize from automation perspective.
Tool/technology Proliferation
Automation tools operate as vendor-locked and tightly coupled
solutions with the technologies without giving the business a way
to control them in a unified and standardized fashion.
Change Management
Alignment
Change is the continuous mantra (maintenance, migration,
integration, retirement etc) in the IT stack and often times the
strategy to align automation remains out of control.
Success Criteria Definition
and Measurement
While ROI remains a known metric, continuous measurement of
the value delivered by automation requires a rich definition of the
success criteria and continuous measurement (with corrective
actions)
Future-proofing automation
assets
The percentage of assets that can be used beyond the scope of
the planned cycles remains an unknown and often times events
like tool migration etc make some of the old assets vendorlocked and void.
