# LogGraphicsStatsRule

`public class LogGraphicsStatsRule`
`` `` `extends LoggingBaseRule` ``

java.lang.Object
↳ | org.junit.rules.ExternalResource
| ↳ | android.support.test.rule.logging.LoggingBaseRule
|  | ↳ | android.support.test.rule.logging.LogGraphicsStatsRule

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 `RunListener`.

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