Class 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.
