Description

Interface Summary
TestRuleIgnoreTestSuites.NestedTestSuite: Marker interface for nested suites that should be ignored if executed in stand-alone mode.

Class Summary
_TestUtil: General utility methods for Lucene unit tests.
English: Converts numbers to english strings for testing.
FailOnNonBulkMergesInfoStream: Hackidy-Häck-Hack to cause a test to fail on non-bulk merges
LineFileDocs: Minimal port of benchmark's LneDocSource + DocMaker, so tests can enum docs from a line file created by benchmark's WriteLineDoc task
LuceneJUnit3MethodProvider: Backwards compatible test* method provider (public, non-static).
LuceneTestCase: Base class for all Lucene unit tests, Junit3 or Junit4 variant.
NullInfoStream: Prints nothing.
QuickPatchThreadsFilter: Last minute patches.
Rethrow: Sneaky: rethrowing checked exceptions as unchecked ones.
RunListenerPrintReproduceInfo: A suite listener printing a "reproduce string".
TestRuleAssertionsRequired: Require assertions for Lucene/Solr packages.
TestRuleFieldCacheSanity: This rule will fail the test if it has insane field caches.
TestRuleIgnoreAfterMaxFailures: This rule keeps a count of failed tests (suites) and will result in an `AssumptionViolatedException` after a given number of failures for all tests following this condition.
TestRuleIgnoreTestSuites: This rule will cause the suite to be assumption-ignored if the test class implements a given marker interface and a special property is not set.
TestRuleMarkFailure: A rule for marking failed tests and suites.
TestRuleStoreClassName: Stores the suite name so you can retrieve it from `TestRuleStoreClassName.getTestClass()`
TestSecurityManager: A `SecurityManager` that prevents tests calling `System.exit(int)`.
ThrottledIndexOutput: Intentionally slow IndexOutput for testing.
TimeUnits: time unit constants for use in annotations.

Annotation Types Summary
LuceneTestCase.AwaitsFix: Annotation for tests which exhibit a known issue and are temporarily disabled.
LuceneTestCase.BadApple: Annotation for tests that fail frequently and should be moved to a "vault" plan in Jenkins.
LuceneTestCase.Nightly: Annotation for tests that should only be run during nightly builds.
LuceneTestCase.Slow: Annotation for tests that are slow.
LuceneTestCase.SuppressCodecs: Annotation for test classes that should avoid certain codec types (because they are expensive, for example).
LuceneTestCase.Weekly: Annotation for tests that should only be run during weekly builds
