-/**
- * Analyzer for testing
- * <p>
- * This analyzer is a replacement for Whitespace/Simple/KeywordAnalyzers
- * for unit tests. If you are testing a custom component such as a queryparser
- * or analyzer-wrapper that consumes analysis streams, its a great idea to test
- * it with this analyzer instead. MockAnalyzer has the following behavior:
- * <ul>
- *   <li>By default, the assertions in {@link MockTokenizer} are turned on for extra
- *       checks that the consumer is consuming properly. These checks can be disabled
- *       with {@link #setEnableChecks(boolean)}.
- *   <li>Payload data is randomly injected into the stream for more thorough testing
- *       of payloads.
- * </ul>
- * @see MockTokenizer
