Package org.apache.lucene.tests.util

General test support. The primary class is LuceneTestCase, which extends JUnit with additional functionality.

Interface Summary

Interface	Description
LuceneTestCase.ThrowingConsumer<T>	A Consumer that can throw any checked exception.
LuceneTestCase.ThrowingRunnable	A runnable that can throw any checked exception.
TestRuleIgnoreTestSuites.NestedTestSuite	Marker interface for nested suites that should be ignored if executed in stand-alone mode.

Class Summary

Class	Description
BaseBitSetTestCase<T extends BitSet>	Base test case for BitSets.
BaseDocIdSetTestCase<T extends DocIdSet>	Base test class for DocIdSets.
English	Converts numbers to english strings for testing.
FailOnNonBulkMergesInfoStream	Hackidy-Häck-Hack to cause a test to fail on non-bulk merges
FailureMarker	A RunListener that detects suite/ test failures.
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.
RamUsageTester	Crawls object graph to collect RAM usage for testing
RamUsageTester.Accumulator	An accumulator of object references.
Rethrow	Sneaky: rethrowing checked exceptions as unchecked ones.
RunListenerPrintReproduceInfo	A suite listener printing a "reproduce string".
StringMockResourceLoader	Fake resource loader for tests: works if you want to fake reading a single file
TestRuleAssertionsRequired	Require assertions for Lucene/Solr packages.
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.
TestRuleLimitSysouts	This test rule serves two purposes: it fails the test if it prints too much to stdout and stderr (tests that chatter too much are discouraged) the rule ensures an absolute hard limit of stuff written to stdout and stderr to prevent accidental infinite loops from filling all available disk space with persisted output.
TestRuleMarkFailure	A rule for marking failed tests and suites.
TestRuleRestoreSystemProperties	Restore a given set of system properties to a snapshot taken at the beginning of the rule.
TestRuleStoreClassName	Stores the suite name so you can retrieve it from TestRuleStoreClassName.getTestClass()
TestSecurityManager	A SecurityManager that prevents tests calling System.exit(int).
TestUtil	General utility methods for Lucene unit tests.
ThrottledIndexOutput	Intentionally slow IndexOutput for testing.
TimeUnits	time unit constants for use in annotations.
VerifyTestClassNamingConvention	Enforce test naming convention.

Annotation Types Summary

Annotation Type	Description
LuceneTestCase.AwaitsFix	Annotation for tests which exhibit a known issue and are temporarily disabled.
LuceneTestCase.BadApple	Annotation for tests that fail frequently and are not executed in Jenkins builds to not spam mailing lists with false reports.
LuceneTestCase.Monster	Annotation for monster tests that require special setup (e.g.
LuceneTestCase.Nightly	Annotation for tests that should only be run during nightly builds.
LuceneTestCase.SuppressCodecs	Annotation for test classes that should avoid certain codec types (because they are expensive, for example).
LuceneTestCase.SuppressFileSystems	Annotation for test classes that should avoid mock filesystem types (because they test a bug that only happens on linux, for example).
LuceneTestCase.SuppressFsync	Annotation for test classes that should avoid always omit actual fsync calls from reaching the filesystem.
LuceneTestCase.SuppressReproduceLine	Suppress the default reproduce with: ant test... Your own listener can be added as needed for your build.
LuceneTestCase.SuppressSysoutChecks	Ignore TestRuleLimitSysouts for any suite which is known to print over the default limit of bytes to System.out or System.err.
LuceneTestCase.SuppressTempFileChecks	Marks any suites which are known not to close all the temporary files.
LuceneTestCase.Weekly	Annotation for tests that should only be run during weekly builds
TestRuleLimitSysouts.Limit	An annotation specifying the limit of bytes per class.
