# mimick_vendor

#### 介绍

mimick_vendor节点

围绕mimick，它提供了一个mimick的外部项目构建。

Mimick旨在成为一个简单易用且功能强大的C代码和lib库。它不依赖于外部代码生成或编译器插件来工作 - 只需将库链接到您的test case

#### 安装教程

1. 下载rpm包

aarch64:

```
wget https://117.78.1.88/build/home:Chenjy3_22.03/openEuler_22.03_LTS_standard_aarch64/aarch64/mimick_vendor/ros-foxy-ros-mimick_vendor-0.2.6-2.oe2203.aarch64.rpm
```

x86_64:

```
wget https://117.78.1.88/build/home:Chenjy3_22.03/openEuler_22.03_LTS_standard_x86_64/x86_64/mimick_vendor/ros-foxy-ros-mimick_vendor-0.2.6-2.oe2203.x86_64.rpm
```

2. 安装rpm包

aarch64:

```
sudo rpm -ivh --nodeps --force ros-foxy-ros-mimick_vendor-0.2.6-2.oe2203.aarch64.rpm
```

x86_64:

```
sudo rpm -ivh --nodeps --force ros-foxy-ros-mimick_vendor-0.2.6-2.oe2203.x86_64.rpm
```

#### 使用说明

依赖环境安装:

```
sh /opt/ros/foxy/install_dependence.sh
```

安装完成以后，在/opt/ros/foxy/目录下如下输出,则表示安装成功。

举一个mimic示例程序 `malloc` function:

```c
#include <stdlib.h>
#include <assert.h>
#include <mimick/mimick.h>

/* Define the blueprint of a mock identified by `malloc_proto`
   that returns a `void *` and takes a `size_t` parameter. */
mmk_mock_define (malloc_mock, void *, size_t);

int main(void) {
    /* Mock the malloc function in the current module using 
       the `malloc_mock` blueprint. */
    mmk_mock("malloc@self", malloc_mock);

    /* Tell the mock to return NULL and set errno to ENOMEM
       whatever the given parameter is. */
    void *result = NULL;
    mmk_when(malloc(mmk_any(size_t)),
            .then_return = &result,
            .then_errno = ENOMEM);

    assert(malloc(42) == result && errno == ENOMEM);

    mmk_reset(malloc);
}
```

另外一种写法:

```c
malloc_mock mock = mmk_mock("malloc@self", malloc_mock);

void *result = NULL;
mmk_when(mock(mmk_any(size_t)),
        .then_return = &result,
        .then_errno = ENOMEM);

assert(malloc(42) == result && errno == ENOMEM);

mmk_reset(mock);
```
