LogGraphicsStatsRule

Class Overview

When applied to a test class this Rule performs a graphics system information reset before test method execution. The Rule then collects graphics system information after test method execution and logs it to a file on external storage. The default file location is maintained at getTestDir(String, String, int). The Rule performs these actions through the execution of a dumpsys on the gfxinfo service.

The Rule's before() and after() methods can also be used for logging battery information across a test suite by manually invoking the methods in a ERROR(RunListener/org.junit.runner.notification.RunListener RunListener).

Usage: \@Rule public LogGraphicsStatsRule mLogGraphicsStatsRule = new LogGraphicsStatsRule();
