#CMock #Ceedling Adding va_list to :treat_as_array: produces a TypeError
gabrielcobostello opened this issue · comments
Hi,
So im using Ceedling to create tests for some inherited code I didnt write. I was looking forward to using CMock so I could avoid having to create mocks myselfs but im running into some issues. Currently im just testing that ceedling works by running empty autogenerated tests.
CMock wrongli mocks the following function:
void tx_push (struct txbuffer *tx, const char *format, va_list ap);
Outputing the following error:
build/test/mocks/mock_txbuffer.c: In function ‘CMockExpectParameters_tx_push’:
build/test/mocks/mock_txbuffer.c:420:31: warning: ‘sizeof’ on array function parameter ‘ap’ will return size of ‘__va_list_tag *’ [-Wsizeof-array-argument]
sizeof(va_list[sizeof(ap) == sizeof(va_list) ? 1 : -1])); /* add va_list to :treat_as_array if this causes an error */
^
build/test/mocks/mock_txbuffer.c:414:149: note: declared here
void CMockExpectParameters_tx_push(CMOCK_tx_push_CALL_INSTANCE* cmock_call_instance, struct txbuffer* tx, int tx_Depth, const char* format, va_list ap)

sizeof(va_list[sizeof(ap) == sizeof(va_list) ? 1 : -1])); /* add va_list to :treat_as_array if this causes an error */
^
ERROR: Shell command failed.
I tried fixing this issue by doing as recommended and adding va_list
to :treat_as_array:
, but now i get a different error:
Test 'test_conn.c'

OVERALL TEST SUMMARY
--------------------
No tests executed.
I just want to make sure that this is not something im doing wrong, in the way I am adding va_list
to :treat_as_array:
, so here is a view of my .yml file :
:cmock:
:mock_prefix: mock_
:when_no_prototypes: :warn
:enforce_strict_ordering: TRUE
:plugins:
- :array
- :ignore
- :callback
:treat_as:
uint8: HEX8
uint16: HEX16
uint32: UINT32
int8: INT8
bool: UINT8
:treat_as_array:
- va_list
:includes:
- <assert.h>
- <getopt.h>
- <libgen.h>
- <stdbool.h>
- <stdint.h>
- <stdio.h>
- <stdlib.h>
- <string.h>
EDIT: My ceedling version (Ubuntu 18.04.2):
Ceedling:: 0.31.1
Unity:: 2.5.4
CMock:: 2.5.4
CException:: 1.3.3
Also If I remove va_list
from :treat_as_array:
I can run tests of modules with depencies succesfully, as long as there are no va_list
functions. So this leads me to think there may be an issue with the way I add va_list
to :treat_as_array:
.
Any help will be greatly appreciated, as I seem to have reached the end of the tunnel as far as solution I can come up with and test. I guess I just want to find out wether this is a mistake on my end, or an unsupported feature as it might be suggested in some other issues :
#397
#204
#129
Best regards,
GCT.
So it seems I was adding the va_list wrongly.
It needs to be :
:treat_as_array:
va_list
Now cmock is no longer complaining about the mocked module.
I couldnt find any examples of how to add something to :treat_as_array:, so hopefully this helps.
