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);
}



/***************************************************************************/
int main()
{
	ut_rt_initialize();

	ut_test_1();

	ut_rt_uninitialize();

	return 0;
}

2. 아래와 같은 결과를 출력

*****************************************************************************
# [simple_suite1] TESTSUITE BEGIN
  :단순 테스트슈트
  time = 1638838733.453190800 sec
