2. Abstract
This paper describes the Hierarchical Automated Test Sequencer Platform (HATS) built on frameworks (EmbedHAT, WinHAT, MobileHAT etc.) which connects to other frameworks or components to provide test automation solutions. This can be a one stop platform which offers test solutions that are spread across embedded, windows and mobile space in enterprise engineering applications in a hierarchical sequence. These solutions can be used for testing of specific target applications or an entire system consisting of embedded devices, software, mobile and cloud applications with added advantages of automated build, monitor, control and reporting viz. is continuous integration. These frameworks can be used independently or in unison based on the need of the test automation.

3. Overview
This whitepaper describes the need for test automation solutions built on frameworks (EmbedHAT, WinHAT, MobileHAT etc.) which connects to other frameworks or components to automate testing of embedded, mobile and software applications singly or in unison.
Trends in market:
Increase in rapid development due to decrease in Time to Market.
Fast changing business needs.
Transformation of legacy systems to revive with latest technological advances.
Complex Systems with more connectivity.
Increase in cost effective maintenance systems.
More players emerging for specific industry areas.
Business Requirement:
A platform where its components together can be used to develop robust, cost effective, minimal maintenance test solutions for complex systems by achieving the test coverage marginally than conventional methods and techniques is required by many conglomerates & manufacturers product line-ups.

4. Growth Prospects
Increasing IT spending – Global test automation increases CAGR of 23.6% between 2016 and 2024.
Increase in budgets in QA and testing(1) from 26% in 2014 to 35% in 2015 with a prediction of 40% in 2018.
Figure: Budgets for QA and Testing over the years.
