            String ignoreEntityClassNamePattern); String getDumpFileEncoding(); void setDumpFileEncoding(String dumpFileEncoding); int getLoadBatchSize(); void setLoadBatchSize(int loadBatchSize); boolean isTransactional(); void setTransactional(boolean transactional); String getGenDialectClassName(); void setGenDialectClassName(String genDialectClassName); boolean isApplyEnvToVersion(); void setApplyEnvToVersion(boolean applyEnvToVersion);  }### Answer:
@Test public void testInit() throws Exception { MigrateCommand command = new MigrateCommand(); command.setConfigPath("s2jdbc-gen-core-test.dicon"); command.setClasspathDir(new File("dir")); command.validate(); command.init(); assertNotNull(command.dialect); assertNotNull(command.sqlFileExecutor); assertNotNull(command.schemaInfoTable); assertNotNull(command.ddlVersionDirectoryTree); assertNotNull(command.entityMetaReader); assertNotNull(command.databaseDescFactory); assertNotNull(command.sqlUnitExecutor); assertNotNull(command.loader); assertNotNull(command.migrater); }
