CUnit安装和测试

CUnit-2.1-2-src.tar.bz2下载地址http://sourceforge.net/projects/cunit/?source=dlp

 

解压压缩包解得到PREFIX/CUnit-2.1-2

 

进入PREFIX/CUnit-2.1-2

 

(如果需要，chmod +x configure)

 

./configure--enable-curses=yes

 

make

 

makeinstall(如果权限不足，请用sudo)

 

默认情况下，CUnit被安装到/usr/local/include/CUnit和/usr/local/lib下面

 

 

安装成功后,我们可以利用mancunit获取帮助信息

 

现在，来测试CUnit

 

首先，编写一段简单的代码

func.c

int maxi(int i, intj)

{

returni > j ? i : j;

}

 

编写测试用例和测试驱动（以下代码参考http://blog.youkuaiyun.com/colin719/article/details/1420583）

test_func.c

#include<stdio.h>

#include<stdlib.h>

#include<assert.h>

#include<CUnit/CUnit.h>

#include<CUnit/Automated.h>

 

/*---- test cases------------------*/

void testIQJ()

{

        CU_ASSERT_EQUAL(maxi(1,1),1);

        CU_ASSERT_EQUAL(maxi(0,-0),0);

}

 

void testIGJ()

{

        CU_ASSERT_EQUAL(maxi(2,1),2);

        CU_ASSERT_EQUAL(maxi(0,-1),0);

        CU_ASSERT_EQUAL(maxi(-1,-2),-1);

}

 

void testILJ()

{

        CU_ASSERT_EQUAL(maxi(1,2),2);

        CU_ASSERT_EQUAL(maxi(-1,0),0);

        CU_ASSERT_EQUAL(maxi(-2,-1),-1);

}

 

CU_TestInfotestcases[] = {

        {"Testing i equals j:",testIQJ},

        {"Testing i greater than j:",testIGJ},

        {"Testing i less than j:",testILJ},

        CU_TEST_INFO_NULL

};

 

 

/*---- test suites------------------*/

intsuite_success_init(void) { return 0; }

intsuite_success_clean(void) { return 0; }

 

CU_SuiteInfosuites[] = {

        {"Testing the functionmaxi:", suite_success_init, suite_success_clean, testcases},

        CU_SUITE_INFO_NULL

};

 

 

/*---- settingenviroment -----------*/

 

void AddTests(void)

{

        assert(NULL != CU_get_registry());

        assert(!CU_is_test_running());

        /* shortcut regitry */

 

        if(CUE_SUCCESS !=CU_register_suites(suites)){

                fprintf(stderr, "Registersuites failed - %s ", CU_get_error_msg());

                exit(EXIT_FAILURE);

        }

}

 

run_test.c

/**

 * file: run_test.c

 **/

 

#include<stdio.h>

#include<stdlib.h>

#include<assert.h>

 

int main( int argc,char *argv[] )

{

       if(CU_initialize_registry()){

                fprintf(stderr, "Initialization of Test Registry failed. ");

                exit(EXIT_FAILURE);

        }else{

                AddTests();

               CU_set_output_filename("TestMax");

                CU_list_tests_to_file();

                CU_automated_run_tests();

                CU_cleanup_registry();

        }

        return 0;

}

 

编写Makefile文件

all: func.ctest_func.c run_test.c

@gcc-o test  $^ -lcunit -static

 

编译，make

 

执行，./test

问题

实验发现必须加上-static选项才行,否则,错误信息如下

参看上面(http://blog.youkuaiyun.com/colin719/article/details/1420583)的内容,如果改为

gcc -o test  func.o test_func.o run_test.o -lcunit -lcurses

也是可以的,可见,libcuni.so需要libcurses.so的支持

icode@icode-G41MT-S2:/mnt/ubuntu/ubuntu_ext/code_work/C$ locate libcurses
/usr/lib/i386-linux-gnu/libcurses.a
/usr/lib/i386-linux-gnu/libcurses.so

当前目录下面生成了TestMax-Listing.xml和TestMax-Results.xml两个文件。

我们将PREFIX/CUnit-2.1-2/Share目录下的CUnit-List.dtd、Cunit-List.xsl、CUnit-Run.dtd、CUnit-Run.xsl四个文件拷贝到当前目录下，用浏览器打开生成的两个文件，显示如下

 

 

以后,就可以用CUnit进行C的单元测试了！！
