android_frameworks_base/tests/SystemMemoryTest/README.txt

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:

  atest -v system-memory-test

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

Log debuggerd -j output when sampling memory use. To get more logging around what GC has occurred over the course of the test. Test: atest -v system-memory-test Bug: 111830582 Change-Id: I11827c78d73f3ddbf5e4e988c99abb96aebdc03a 2018-09-06 13:31:10 +01:00			`atest -v system-memory-test`
