cca

설명

• CodeCoverage Analysis Tool
• ccs(TI Code Composer Studio) Compiler를 위한 CodeCoverage 분석기

1. 컴파일러를 통해서 코드 수행 csv파일을 아래와 같이 얻는 경우

"filename","funcname",line number,column number,frequency count,"comment""D:\prj\hcpu\hcpu-A-002\hcpu\src\app/application2.h","app_msg",3,2,1,"console_device_printfln("app_msg")""D:\prj\hcpu\hcpu-A-002\hcpu\src\app/application2.h","app_msg",5,2,1,"return ""D:\prj\hcpu\hcpu-A-002\hcpu\src\app/application2.h","app_msg",2,1,1,"goto g-1#1"

2. csv파일을 읽어서 아래와 같이 분석 결과를 출력

=============================================================================

ut

설명

• UnitTest Library (C)
• 마이크로 프로세서(MCU)에서 사용하기 위해서 개발 된 유닛 테스트 라이브러리

1. 아래와 같이 테스트 코드 작성 하여 실행 하면

/***************************************************************************/
#include"../ut/ut.h"
#include"ut_test_1.h"/***************************************************************************//* 테스트케이스 */ut_testcase(simple_case1, "단순 테스트케이스1")
{
ut_testassert(1 == 0);
ut_testassert(1 == 1);
}
ut_testcase(simple_case2, "단순 테스트케이스2")
{
void* param = ut_testcontext_get_param();
int* value = (int*)param;
ut_printfln("파라메터: %d", *value);
ut_testassert(3 == 3);
ut_testassert(3 == 3);
}
/***************************************************************************//* 테스트슈트 */ut_testsuite_case_begin(simple_suite1)
ut_testsuite_case(simple_case1)
ut_testsuite_case(simple_case2)
ut_testsuite_case_end()
ut_testsuite(simple_suite1, "단순 테스트슈트")
/***************************************************************************/
void ut_test_1(void)
{
int param = 3;
ut_testrunner(ut_testsuite_instance(simple_suite1), &param, ut_nullptr);
}
/***************************************************************************/intmain()
{
ut_rt_initialize();
ut_test_1();
ut_rt_uninitialize();
return0;
}

2. 아래와 같은 결과를 출력
