Class SystemPropertyOverrides

java.lang.Object

com.android.testutils.SystemPropertyOverrides

All Implemented Interfaces:

java.lang.AutoCloseable

public class SystemPropertyOverrides
extends java.lang.Object
implements java.lang.AutoCloseable

Utility to make it easier for tests to override system properties (instead of directly using System.setProperty(String, String)). By using this class within try-with-resources, the test can be assured that any property set will be restored to its initial state after the test completes (success & failure).
