### Question:
SchemaMigrations { static ConfigurationTransformation initialTo1() { return ConfigurationTransformation.builder() .addAction(new Object[]{WILDCARD_OBJECT, WILDCARD_OBJECT}, MOVE_PREFIX_SUFFIX_ACTION) .addAction(new Object[]{WILDCARD_OBJECT, WILDCARD_OBJECT, "worlds", WILDCARD_OBJECT}, MOVE_PREFIX_SUFFIX_ACTION) .build(); } private  SchemaMigrations();  static final int LATEST_VERSION; }### Answer:
@Test public void testInitialToOne(@TempDir Path tempFolder) throws IOException { final Path testFile = tempFolder.resolve("Test0to1.yml"); ConfigurationLoader<ConfigurationNode> yamlLoader = YAMLConfigurationLoader.builder() .setPath(testFile) .setURL(getClass().getResource("test0to1.pre.yml")) .setFlowStyle(DumperOptions.FlowStyle.BLOCK) .build(); ConfigurationNode node = yamlLoader.load(); SchemaMigrations.initialTo1().apply(node); yamlLoader.save(node); assertEquals(Resources.readLines(getClass().getResource("test0to1.post.yml"), UTF_8), Files.readAllLines(testFile, UTF_8)); }
