And the great thing about this is that the diff document can then be merged with the first JSON document that has been compared, yielding the second JSON document that has been compared. The approach described in the other post focus in producing a JSON document that represents the differences between the two documents that have been compared.
#JUNIT JSON COMPARE HOW TO#
I recently put together another post describing how to compare JSON documents using JSON-P. Quoting the RFC 8259, the document that defines the JSON format (highlights are mine):Īn object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.Īn array is an ordered sequence of zero or more values. This comparison method doesn’t take into account the order of the properties of objects, but it does take into account the order of the elements in arrays. It will produce the following output: Entries only on left println ( "\n\nEntries in common\n-" ) difference. println ( "\n\nEntries differing\n-" ) difference. println ( "\n\nEntries only on right\n-" ) difference. println ( "Entries only on left\n-" ) difference. difference ( leftFlatMap, rightFlatMap ) System. flatten ( rightMap ) MapDifference difference = Maps. flatten ( leftMap ) Map rightFlatMap = FlatMapUtil. Add all the data into a list of objects and return it This allows us to write our tests in the following manner. We need to use dynamic here as we don't know the types passed into TestObject at compile-time, and they can change for each test. When strict is set to false (recommended), it forgives reordering data and extending results (as long as all the expected elements are there), making tests less brittle. Parse the file data as JSON Deserialize the JSON data as the genericType and store it in a dynamic type.
Answers related to creating json objects for junit. Under the covers, JSONassert converts your string into a JSON object and compares the logical structure and data with the actual JSON. Lets start with preparing the environment to. String message JSONObject json new JSONObject() json.put(name, student) JSONArray array.
It uses the JSON Pointer notation defined in the RFC 6901 for the keys, so I can easily locate the values. JSON with Java, This chapter covers how to encode and decode JSON objects using Java programming language. Import import import import import import import public final class FlatMapUtil
