DESCRIPTION
FUNCTIONS
gen_test_func
Usage:
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 "args", will execute this code
instead.
* posttest (code)
Run this code for additional tests.
Todo:
* Handle function with "result_naked" => 1.
This function is not exported by default, but exportable.
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.
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.
Return value: (any)
