'm building a jUnit test case for my GAE hosted service and one of the methods
is having issues.
Here is the Resource interface:
public interface BasketItemResource {
@Delete
public void removeBasketItem(String id);
@Get
public Representation listBasketItems();
@Put
public void addBasketItems(Representation items);
}
and here are my test cases:
@Test
public void testListItems() {
Gson gson = new Gson();
List<BasketItem> items = null;
JsonRepresentation jRep = null;
Type collectionType = new TypeToken<List<BasketItem>>(){}.getType();
try {
jRep = new JsonRepresentation(resource.listBasketItems());
items = gson.fromJson(jRep.getJsonArray().toString(), collectionType);
} catch (JsonSyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
assertEquals(items.size(), 5);
}
@Test
public void testAddItem() {
Gson gson = new Gson();
BasketItem b = new BasketItem();
b.basketItemID = 123;
b.brandName = "Pepsi";
b.description = "Cola Beverage";
b.upc = "123123123";
List<BasketItem> items = new ArrayList<BasketItem>();
items.add(b);
JsonRepresentation jRep = null;
try {
jRep = new JsonRepresentation(new JSONArray(gson.toJson(items)));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
resource.addBasketItems(jRep);
}
The listItems test executes fine but when I run the testAddItems() I first get
this warning:
