Try Skyscreamer’s JSONAssert.
Its non-strict mode has two major advantages that make it less brittle:
- Object extensibility (e.g. With an expected value of {id:1}, this would still pass: {id:1,moredata:’x’}.)
- Loose array ordering (e.g. [‘dog’,’cat’]==[‘cat’,’dog’])
In strict mode it behaves more like json-lib’s test class.
A test looks something like this:
@Test
public void testGetFriends() {
JSONObject data = getRESTData("/friends/367.json");
String expected = "{friends:[{id:123,name:\"Corby Page\"}"
+ ",{id:456,name:\"Solomon Duskis\"}]}";
JSONAssert.assertEquals(expected, data, false);
}
The parameters in the JSONAssert.assertEquals() call are expectedJSONString, actualDataString, and isStrict.
The result messages are pretty clear, which is important when comparing really big JSON objects.
