#JUNIT JSON COMPARE HOW TO#

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. If you need to add a property with a null value, you should use the predefined static final JSONObject.NULL and not the standard Java null reference. 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. Lets start with preparing the environment to. This has a number of advantages over a straight.

#JUNIT JSON COMPARE HOW TO#

I recently put together another post describing how to compare JSON documents using JSON-P. JSON with Java, This chapter covers how to encode and decode JSON objects using Java programming language. The equalToJson match operator performs a semantic comparison of the input JSON against the expected JSON. 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. The extension supports the following test frameworks: JUnit 4 (v4.8.0+) JUnit 5 (v5. It will produce the following output: Entries only on left Its a lightweight extension to run and debug Java test cases. The way that Map.equals () works is by comparing keys and values using the Object.equals () method. Then we’re using Map.equals () to check if two HashMaps have the same entries. Here, we’re creating two HashMap objects and adding entries. println ( ' Entries in common -' ) difference. Lets write a Java program to demonstrates comparing two HashMap using Map.equals () method. println ( ' Entries differing -' ) difference. Difference between Neo4j Graph Algorithms and Graph Data Science. println ( ' Entries only on right -' ) difference. The JSON path format follows the Java implementation by Jayway of Stefan Gssners. println ( 'Entries only on left -' ) difference. difference ( leftFlatMap, rightFlatMap ) System. flatten ( rightMap ) MapDifference difference = Maps. flatten ( leftMap ) Map rightFlatMap = FlatMapUtil. It uses the JSON Pointer notation defined in the RFC 6901 for the keys, so I can easily locate the values. Import import import import import import import public final class FlatMapUtil
