@Test public void testJsonToMapWithList() { Map<String, String> map = JsonUtils.jsonToStringMapWithList(new StringReader(JSON_STRING_WITH_ARRAYS)); Map<String, String> actualMap = new HashMap<>(); actualMap.put("string", "string"); actualMap.put("long", "123"); actualMap.put("double", "123.45"); actualMap.put("null", null); actualMap.put("true", "true"); actualMap.put("false", "false"); actualMap.put("encoding", "Chloë"); actualMap.put("array", "[\"string\",\"123\",\"123.45\",null,\"true\",\"false\"]"); actualMap.put("array2", "[{\"key1\":\"string1\"},{\"key2\":\"string2\"}]"); actualMap.put("array3", "[{\"key1\":\"123.45\"},{\"key2\":\"false\"}]"); actualMap.put("array4", "[\"string\",\"123\",\"123.45\",null,\"true\"]"); actualMap.put("array5", "[{\"key1\":\"string1\"},{},{\"key3\":\"string3\"}]"); actualMap.put("array6", "[]"); actualMap.put("array7", "[]"); actualMap.put("array8", "[null]"); actualMap.put("array9", "[\"A\",{},\"C\",\"D\",null]"); assertEquals(actualMap, map); }
