public abstract class BaseTokenStreamTestCase extends LuceneTestCase
Base class for all Lucene unit tests that use TokenStreams.When writing unit tests for analysis components, it's highly recommended to use the helper methods here (especially in conjunction with
MockAnalyzerorMockTokenizer), as they contain many assertions and checks to catch bugs.- See Also:
MockAnalyzer,MockTokenizer
