FUNCTIONS

None are exported by default, but they are exportable.

gen_test_func(%args) -> [status, msg, result, meta]

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.
