### Question:
DumpDataCommand extends AbstractCommand { public void setClasspathDir(File classpathDir) { this.classpathDir = classpathDir; } DumpDataCommand(); File getClasspathDir(); void setClasspathDir(File classpathDir); String getEntityPackageName(); void setEntityPackageName(String entityPackageName); String getEntityClassNamePattern(); void setEntityClassNamePattern(String entityClassNamePattern); String getIgnoreEntityClassNamePattern(); void setIgnoreEntityClassNamePattern(
            String ignoreEntityClassNamePattern); String getRootPackageName(); void setRootPackageName(String rootPackageName); File getDumpDir(); void setDumpDir(File dumpDir); String getDumpFileEncoding(); void setDumpFileEncoding(String dumpFileEncoding); String getGenDialectClassName(); void setGenDialectClassName(String genDialectClassName); File getDdlInfoFile(); void setDdlInfoFile(File ddlInfoFile); String getVersionNoPattern(); void setVersionNoPattern(String versionNoPattern); String getDumpDirName(); void setDumpDirName(String dumpDirName); File getMigrateDir(); void setMigrateDir(File migrateDir); boolean isApplyEnvToVersion(); void setApplyEnvToVersion(boolean applyEnvToVersion); boolean isTransactional(); void setTransactional(boolean transactional);  }### Answer:
@Test public void testInit() throws Exception { DumpDataCommand command = new DumpDataCommand(); command.setConfigPath("s2jdbc-gen-core-test.dicon"); command.setClasspathDir(new File("dir")); command.validate(); command.init(); assertNotNull(command.dialect); assertNotNull(command.sqlUnitExecutor); assertNotNull(command.entityMetaReader); assertNotNull(command.databaseDescFactory); assertNotNull(command.dumper); assertNotNull(command.ddlVersionDirectoryTree); }
