### Question:
AllocationIdUtil { public static String generateAllocationId(final int index, final int version) { return "#" + convertDecimalToBase26(index) + version; }  static String getAllocationName(final String allocId); static Set<Allocation> getOutdatedAllocations(final TestDefinition previous, final TestDefinition current); static String getNextVersionOfAllocationId(final String allocId); static String generateAllocationId(final int index, final int version); static int convertBase26ToDecimal(final char[] chars); static final Comparator<String> ALLOCATION_ID_COMPARATOR; }### Answer:
@Test public void testGenerateAllocationId() { assertEquals("#A1", AllocationIdUtil.generateAllocationId(0, 1)); assertEquals("#Z2", AllocationIdUtil.generateAllocationId(25, 2)); assertEquals("#BA1", AllocationIdUtil.generateAllocationId(26, 1)); }
