They don't run during normal test runs because they're not tests--they don't assert anything. Also, they're a bit slow. These differ from the ones in test_benchmarks in that these are meant to be compared from revision to revision of Parsimonious to make sure we're not getting slower. test_benchmarks simply makes sure our choices among implementation alternatives remain valid. )print_functionN)repeat)Grammarcd}dj|gdz}d|zdztdd}d}ttfd d || }||z }t d z }t d ||||z fzy)a[As a baseline for speed, parse some JSON. I have no reason to believe that JSON is a particularly representative or revealing grammar to test with. Also, this is a naive, unoptimized, incorrect grammar, so don't use it as a basis for comparison with other parsers. It's just meant to compare across versions of Parsimonious. a{ "id" : 1, "married" : true, "name" : "Larry Lopez", "sons" : null, "daughters" : [ { "age" : 26, "name" : "Sandra" }, { "age" : 25, "name" : "Margaret" }, { "age" : 6, "name" : "Mary" } ] },<z{"fathers" : [z]}a value = space (string / number / object / array / true_false_null) space object = "{" members "}" members = (pair ("," pair)*)? pair = string ":" value array = "[" elements "]" elements = (value ("," value)*)? true_false_null = "true" / "false" / "null" string = space "\"" chars "\"" space chars = ~"[^\"]*" # TODO implement the real thing number = (int frac exp) / (int exp) / (int frac) / int int = "-"?
