org.skyscreamer.jsonassert.comparator.ArraySizeComparator

A JSONAssert array size comparator.

Some typical usage idioms are listed below.

Assuming JSON to be verified is held in String variable ARRAY_OF_JSONOBJECTS and contains:

{a:[7, 8, 9]}

then:

To verify that array 'a' contains 3 elements:

JSONAssert.assertEquals("{a:[3]}", ARRAY_OF_JSONOBJECTS, new ArraySizeComparator(JSONCompareMode.LENIENT));

To verify that array 'a' contains between 2 and 6 elements:

JSONAssert.assertEquals("{a:[2,6]}", ARRAY_OF_JSONOBJECTS, new ArraySizeComparator(JSONCompareMode.LENIENT)); @author Duncan Mackinder

    doTest("a", new ArrayValueMatcher<Object>(comparator, 0), "{a:[[6,7,8]]}", ARRAY_OF_JSONARRAYS);
  }


  @Test
  public void matchesSizeOfFirstThreeInnerArrays() throws JSONException {
    JSONComparator innerArraySizeComparator = new ArraySizeComparator(JSONCompareMode.STRICT_ORDER);
    doTest("a", new ArrayValueMatcher<Object>(innerArraySizeComparator, 0, 2), "{a:[[3]]}", ARRAY_OF_JSONARRAYS);
  }

    doTest("a", new ArrayValueMatcher<Object>(innerArraySizeComparator, 0, 2), "{a:[[3]]}", ARRAY_OF_JSONARRAYS);
  }


  @Test
  public void failsWhenInnerArraySizeDoesNotMatch() throws JSONException {
    JSONComparator innerArraySizeComparator = new ArraySizeComparator(JSONCompareMode.STRICT_ORDER);
    doFailingMatchTest("a",
        new ArrayValueMatcher<Object>(innerArraySizeComparator),
        "{a:[[3]]}",
        ARRAY_OF_JSONARRAYS,
        "a\\[3\\]\\[\\]\\s*Expected:\\s*array size of 3 elements\\s*got:\\s*4 elements\\s*");

     JSONAssert.assertEquals("{a:[{background:white},{background:grey}]}", ARRAY_OF_JSONOBJECTS, new CustomComparator(JSONCompareMode.LENIENT, customization));
  }
  
  @Test
  public void verifyEveryElementOfArrayIsJSONArrayOfLength3() throws JSONException {
     JSONComparator comparator = new ArraySizeComparator(JSONCompareMode.STRICT_ORDER);
     Customization customization = new Customization("a", new ArrayValueMatcher<Object>(comparator, 0, 2));
     JSONAssert.assertEquals("{a:[[3]]}", ARRAY_OF_JSONARRAYS, new CustomComparator(JSONCompareMode.LENIENT, customization));
