Package org.apache.solr.util

Class TestInjection

java.lang.Object

org.apache.solr.util.TestInjection

public class TestInjection
extends Object

Allows random faults to be injected in running code during test runs.

Set static strings to "true" or "false" or "true:60" for true 60% of the time.

All methods are No-Ops unless LuceneTestCase is loadable via the ClassLoader used to load this class. LuceneTestCase.random() is used as the source of all entropy.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
