how to Mockup map class and mock return map.size












1















I'm improving my coverage rate. So I try to enter a special condition by mock a map size, but I fail to do so. Does this method working with the original type such as map.class because I used the same method on my other class and they work fine?



Item i = new Item();
ItemTbl tbl = new ItemTbl();
tbl.setMerchantId(key.getMerchantId());
tbl.setBaseSku(key.getBaseSku().toUpperCase());
tbl.setOrigBaseSku(key.getBaseSku());
i.setItemTbl(tbl);
final Map<String, Item> existingItems = prepareExistingData(Arrays.asList(i), false, false);

Item existingItem;
existingItem = existingItems.get(tbl.getBaseSku());

if (existingItem == null) {
return null; //original item api return 200 if item not found
}

if (existingItem.getShopItemMap() != null) {
if (existingItems.size() == 1) {
//the thing I want to cover
}
}


Junit test:



new MockUp<Map<String, Item>>() {
@Mock
public int size() {
return 2;
};
};

fixture.delete(entity);


I notice the existingItems is set as final, but I tried to delete final, but it still not work.

  • Why do you need to mock a Map? Cannot you just return a HashMap with two elements from your (mocked version of) prepareExistingData ?

  • @Raedwald I use mockit currently. I tried mockito, but still no luck

  • @Thilo Because the data are too complicated to makeup which I still need to use in if statement, and I am wonder why it doesn't work.

I suggest you mock the behavior of size() on existingItems specifically.
It would look something like this:



when(existingItems.size()).thenReturn(2);
