### Question:
ProjectMetadata extends AbstractMetadataItem { public static String getModuleName(final String metadataIdentificationString) { if (metadataIdentificationString.contains(MODULE_SEPARATOR)) { return StringUtils.substringAfterLast(metadataIdentificationString, MODULE_SEPARATOR); } return ""; } ProjectMetadata(final Pom pom); static String getModuleName(final String metadataIdentificationString); static String getProjectIdentifier(final String moduleName); static boolean isValid(final String metadataIdentificationString); String getModuleName(); Pom getPom(); @Override final String toString();  }### Answer:
@Test public void testGetModuleNameFromLevelOneModuleMID() { assertEquals(LEVEL_ONE_MODULE, ProjectMetadata.getModuleName(LEVEL_ONE_MID)); }
@Test public void testGetModuleNameFromRootModuleMID() { assertEquals("", ProjectMetadata.getModuleName(ROOT_MID)); }
