Better support for testing JSON [SPR-16737]

[spring-projects-issues]

Kamil opened SPR-16737 and commented

Reactive WebTestClient is using JsonPath assertions like: ```
jsonPath("$[0]['gender']")

It would be so good, if you could provide "AssertJ like" fluent API to test JSONs...

WebTestClient supports JSONAssert for comparing full JSON content and JSONPath for extracting and matching specific values. Use whichever one you prefer or fits the case. Also the API is fluent so it's not clear what you mean. Perhaps there are other assertions you'd like to see? Please be more specific.

As an aside, at various places in the API, there are java.util.function.Consumer callbacks (e.g. test) that expose the underlying data. Those hooks can be used to plug any assertion library.
