Hamcrest matchers for JSON

[SudhirR]

Hi,

Could not find one that can be used for JSON key, value, path matching. If available please point me to it.

Regards.

I'm not sure what you mean by this; do you want a matcher that will act on an encoded JSON string? Or one that will work on the decoded object? If the former, you're right -- there isn't one in the core distribution.

assert_that(json.dumps(str)), ...)

Perhaps you can explain in more detail what you want?

[SudhirR]

I am looking for the java version which does something like

assertThat(jsonObject, allOf(
  hasPath("one.two.three[3].four"),
  hasValueInPath("one.two.three[0].four.key", "value"),
  // and so on
));

This is for testing complete JSON structure in one shot. Currently we are relying on having an expected JSON and doing a toString match.

I have started with a hamcrest extension here - http://code.google.com/p/jsonmatcher

I recommend adding Json to the names, e.g. hasJsonPath. This is to distinguish them from hasXpath and friends.
