JSONSelect JS parser tests

Selectors

$ JSONSelect._parse(".foo");
[{id: "foo"}]
$ JSONSelect._parse('." foo "');
[{id: " foo "}]
$ JSONSelect._parse("string.foo:last-child");
[{a: 0, b: 1, id: "foo", pf: ":nth-last-child", type: "string"}]
$ JSONSelect._parse("string.foo.bar");
Error: multiple ids not allowed
$ JSONSelect._parse("string.foo:first-child.bar");
Error: multiple ids not allowed

Error: string required after '.'

Error: selector expected
$ JSONSelect._parse("");
Error: selector expected

Combinators

[",", [{id: "foo", type: "string"}], [{id: "foo", type: "number"}]]
$ JSONSelect._parse("string > .foo number.bar");
[{type: "string"}, ">", {id: "foo"}, {id: "bar", type: "number"}]
