LogDeviceGetPropInfoRule

public class LogDeviceGetPropInfoRule
extends LoggingBaseRule

java.lang.Object
   ↳ org.junit.rules.ExternalResource

       ↳ android.support.test.rule.logging.LogDeviceGetPropInfoRule


When applied to a test class this Rule executes the "getprop" device command after test method execution and logs it to a file on external storage. The default file location is retrieved via getTestDir(String, String, int).

The Rule logs the runtime build number, device name, build type, lcd density, cpu type, among many other device state attributes. When used in conjunction with a device lab it might assist in identifying trends in test failures for a subset of Android devices.

The pertinent information output by this rule typically doesn't change between tests, therefore, it is typically used manually by using the before() and after() methods in a RunListener.

Usage: \@Rule public LogDeviceGetPropInfoRule mLogDeviceGetPropInfoRule = new LogDeviceGetPropInfoRule();
