Testing jq-go

[suntong]

The API interface, at least in all test files, looks really strange to me, as I'm expecting JSON string as input (and the outputs are normally JSON string as well). However, all test cases covered are just using a series of integers as input, which is quite unusual.

Would it be possible that you extend the test coverage to normal JSON strings as well? For e.g., you can use the following operation, input and output. Thanks.

.foo
{"foo": 42, "bar": 43}
42

.foo | .bar
{"foo": {"bar": 42}, "bar": "badvalue"}
42

.foo.bar
{"foo": {"bar": 42}, "bar": "badvalue"}
42

.foo_bar
{"foo_bar": 2}
2

.["foo"].bar
{"foo": {"bar": 42}, "bar": "badvalue"}
42

."foo"."bar"
{"foo": {"bar": 20}}
20

[.[]|.foo?]
[1,[2],{"foo":3,"bar":4},{},{"foo":5}]
[3,null,5]

[.[]|.foo?.bar?]
[1,[2],[],{"foo":3},{"foo":{"bar":4}},{}]
[4,null]
