在应用于测试类时，此Rule在执行测试方法之前执行图形系统信息重置。 Rule然后在测试方法执行后收集图形系统信息并将其记录到外部存储器上的文件中。 默认文件位置保持在getTestDir(String, String, int) 。 该规则通过执行gfxinfo服务上的gfxinfo来执行这些操作。

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 RunListener.

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