# JsonDiff library

The main purpose of the library is integration into tests which use json and providing human-readable output of test results.

The lib can compare two json items and return a detailed report of the comparison.

At the moment it can detect a couple of types of differences:

 - FullMatch - means items are identical.
 - SupersetMatch - means first item is a superset of a second item.
 - NoMatch - means objects are different.

Being a superset means that every object and array which don't match completely in a second item must be a subset of a first item. For example:

```json
{"a": 1, "b": 2, "c": 3}
```

Is a superset of (or second item is a subset of a first one):

```json
{"a": 1, "c": 3}
```
