PROJECTS

Framework for Graphics driver validation - Android Intel Apr '11

- Mar '12

Designed and developed the automation framework for validating the display

driver features on Android. The framework is built with capability to do

white box testing and provide extensive coverage. Framework can support

test cases to be run in application mode or in console mode.

OS : Android

Language : C, Java

Responsibilities:

. Understood the android fundamentals to design the validation

framework.

. Developed kernel driver to add hooks for testing the display driver.

. Used KProbes and JProbes to validate the function hits and analyze

arguments

. Enabled the framework to support console mode tests by disabling

SurfaceFlinger.

. Used configuration files to change the tests behavior dynamically.

Framework for Graphics driver validation - Windows Intel Nov '09

- Mar '11

Designed and developed automation framework with capabilities to add new

test cases easily. The framework is being used extensively in testing of

various components of Display architecture. Automated test cases were

pushed into regular test execution cycles and many bugs that were not

caught in manual execution were found

OS : Windows

Language : C#

Responsibilities:

. Explored Windows APIs to validate graphics features and enabled many

tests with those APIs.

. Enabled white box testing with escape calls in the driver.

. Developed CRC framework to check for corruption.

. Automated many HAL test cases with this framework.

. Tested the framework on different platforms and operating systems.

Antispam Request Server Symantec Feb

'09 - Oct '09

The Antispam Request Servers receive spam requests from NIS clients and

provides verdict based on the content of mail by integrating with new

technology. The server can handle about 2000 requests/sec.

OS : Linux

Language : C

Responsibilities:
