 *       {@link Extractor#init(ExtractorOutput)} to check these calls do not fail.

 *       boolean, boolean)} with all possible combinations of "simulate" parameters.
 * </ul>
 *
 * @param factory An {@link ExtractorFactory} which creates instances of the {@link Extractor}
 *     class which is to be tested.
 * @param file The path to the input sample.
 * @param dumpFilesPrefix The dump files prefix appended to the dump files path.
 * @throws IOException If reading from the input fails.
