Initial setup of a SystemMemoryTest. 

Set up a memory test to experiment with actionable memory metrics and
detect regressions in system server memory use.

The initial CUJ is to launch an instrumentation that does nothing for
a few seconds.

The initial metric is to read showmap for system_server and report
VSS, RSS, and PSS.

The CUJ and metrics will be made more interesting once the basic
infrastructure for continuously running the test is set up.

Bug: 111830582
Test: tradefed.sh run commandAndExit template/local_min --template:map test=system-memory-test

This directory contains a test for system server memory use.



Directory structure

===================

device

  - those parts of the test that run on device.



host

  - those parts of the test that run on host.



Running the test

================



You can manually run the test as follows:



  make tradefed-all system-memory-test SystemMemoryTestDevice

  tradefed.sh run commandAndExit template/local_min --template:map test=system-memory-test



This installs and runs the test on device. You can see the metrics in the

tradefed output.
