SYNOPSIS
     use Gen::Test::Rinci::FuncResult qw(gen_test_func);
     use Test::More;

     sub divide {
         my %args = @_;
         my ($a, $b) = ($args{a}, $args{b});
         return [500, "undefined"] if $a == 0 && $b == 0;
         [200, "OK", $a/$b];
     }

     gen_test_func(name => 'test_divide', func => \&divide);

     test_divide(args=>{a=>6, b=>3}, result=>2);
     test_divide(args=>{a=>6, b=>0}, dies=>1);
     test_divide(args=>{a=>0, b=>0}, status=>500);
     done_testing;

DESCRIPTION
FUNCTIONS
  gen_test_func(%args) -> [status, msg, result, meta]
    Generate a test function for a function.

    This function (A) will generate a function (B).

    A accepts, among others, the name or the reference to the function that
    you want to test (T) and the name of the generated function, B.

    B will run T once with some specified arguments, catch exception, and
    test its result. The result is expected to be an enveloped result (see
    the documentation of "Rinci::function" for more details about enveloped
    result).

    B will accept the following arguments:

    *   name (str)

          Name of the test. Will default to "T (ARGS...)" to show the name of the target
          function and the arguments that it is called with.

    *   args (hash or array)

          Argument to feed to function T.

    *   dies (bool, default => 0)

          Whether function T should die when run. If set to 1, further tests will not be
          done except the test that function dies.

    *   status (int, default => 200)

          Will test the result's status code.

    *   result (any)

          If specified, will test the actual result of the function.

    *   run (code)

          Instead of running function T with C<args>, will execute this code instead.

    *   posttest (code)

          Run this code for additional tests.

    Todo:

    *   Handle function with "result_naked" => 1.

    Arguments ('*' denotes required arguments):

    *   func* => *code*

        Target function to test.

    *   install => *bool* (default: 1)

        Whether to install the function.

    *   name* => *str*

        Name of the test function to generate (B).

        Can be fully qualified, e.g. "Pkg::SubPkg::funcname" or unqualified
        "funcname" (where the package will be taken from the "package"
        argument). Relevant for when installing the function.

    *   package => *any*

        Perl package to put this function in.

        Relevant only when installing the function.

    Return value:

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (result) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.
