C++测试驱动开发环境搭建--笔记

1.Google Mock

Google Mock这个链接包含googleTest项目，里面包含了google mock。所以一起安装GoogleMock和Goo
gleTest.

# 设置变量GMOCK_DIR和GTEST_DIR为我们源代码位置
# 生成gtest-all.o
g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
    -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
    -pthread -c ${GTEST_DIR}/src/gtest-all.cc
# 生成gmock-all.o
g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
    -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
    -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
# 静态库libgmock.a
ar -rv libgmock.a gtest-all.o gmock-all.o

测试

g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
    -pthread path/to/your_test.cc libgmock.a -o your_test
./your_test

### 2.CppUTest
[cpputest](https://github.com/cpputest/cpputest)




<div class="se-preview-section-delimiter">div>

```shell
cd cpputest_build
autoreconf .. -i
../configure
make
make check 
make install

测试

#include "../inc/ClassName.h"
#include "CppUTest/CommandLineTestRunner.h"
#include "CppUTest/UtestMacros.h"

    CHECK_EQUAL(1,1);
    LONGS_EQUAL(1,1);
    DOUBLES_EQUAL(1.000, 1.001, .01);
    STRCMP_EQUAL("hello", "hello");
    FAIL("The prior tests pass, but this one doesn't");
}

int main(int ac, char** av)
{
    return RUN_ALL_TESTS(ac, av);
}

编译
