/** \mainpage ROC Profiler Multi Process Binary Test
|
|
*
|
|
* \section introduction Introduction
|
|
*
|
|
* The goal of this test is to test ROC profiler as a binary against a
|
|
* multiprocess application.Test application launches an empty kernel
|
|
* on multiple threads from both parent and child process.
|
|
*
|
|
* The test then parses the csv and verifies if the nuber of context collected
|
|
* are equal to number of threads launched in test application.
|
|
*
|
|
* Test also does some basic verification if counter values are non-negative
