我正在为一些非开源代码的继承代码开发一些单元测试。到目前为止，我一直在测试ceedling框架，使用自动生成的测试来确保一切正常运行。
当我为没有依赖关系的模块运行测试时，一切都很好，但是当我为一个有一堆依赖关系的模块运行测试时(我必须包括作为模拟):
#ifdef TEST
#include "unity.h"
#include "conn.h"
#include "mock_log.h"
#include "mock_memory.h"
#include "mock_rxbuffer.h"
#include "mock_txbuffer.h"
void setUp(void)
{
}
void tearDown(void)
{
}
void test_conn_NeedToImplement(void)
{
TEST_IGNORE_MESSAGE("Need to Implement conn");
}
#endif // TEST
Ceedling模拟以下函数时遇到错误:
void tx_push (struct txbuffer *tx, const char *format, va_list ap)
错误如下:
Test 'test_conn.c'
------------------
Generating runner for test_conn.c...
Compiling test_conn_runner.c...

build/test/mocks/mock_txbuffer.c: In function ‘CMockExpectParameters_tx_push’:

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

^
ERROR: Shell command failed.
因此，根据消息的建议，我将va_list添加到:treat_as_array:
: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>
这样做之后，我最终得到了一个新的错误(在调试中运行ceedling)，格式为:

OVERALL TEST SUMMARY
--------------------
No tests executed.
如果我从:treat_as_array中删除va_list，我可以成功地测试具有依赖关系的模块，只要它们没有将va_list作为输入的函数。否则，即使没有va_list函数，我仍然会得到相同的错误:
TypeError: no implicit conversion of String into Integer
所以在我看来，我将va_list包含到:treat_as_array的方式可能存在问题?
到了这个时候，我几乎不知道该尝试什么了。我也在github上为ceedling打开了一个问题，说明了这个问题，但我希望从其他可能遇到这个问题的ceedling用户那里得到一些输入。
我的初始版本如下(Ubuntu 18.04.2):
Ceedling:: 0.31.1
Unity:: 2.5.4
CMock:: 2.5.4
CException:: 1.3.3
我在这里看到的堆栈交换中有一个类似的问题，但是没有将va_list添加到:treat_as_array的额外步骤。
并且有几个github问题讨论缺乏对变量函数的支持:
https://github.com/ThrowTheSwitch/CMock/issues/397- https://github.com/ThrowTheSwitch/CMock/issues/204
- https://github.com/ThrowTheSwitch/CMock/issues/129
所以我想我只是想弄清楚这是一个不支持的功能还是我做错了什么。
任何帮助都将不胜感激。
最诚挚的问候,GCT。
所以看来我添加va_list是错误的。
必须是:
:treat_as_array:
va_list
现在cmock不再抱怨被模拟的模块。
我找不到任何例子如何添加一些东西到:treat_as_array:，所以希望这有助于。
