c - 单元测试中的段错误

Question

我使用 unity 函数测试了我的 C 代码以进行单元测试。它显示错误和段错误？单元测试失败后通常会出现段错误吗？或者我的代码有问题？因为，当我纠正错误时，它运行成功

time.c

//gets start time and duration in 24 hour format and returns the total of the two in 24 hour clock


int add_time(int starttime, int duration)
{
     int startHour = starttime / 100;
     int startMinute = starttime % 100;
     int durationHour = duration / 100;
     int durationMinute = duration % 100;

     int finishHour = startHour + durationHour;
     int finishMinute = startMinute + durationMinute;

     if(finishMinute > 59)
     {
         finishMinute %= 60;
        finishHour++; 
    }

     finishHour %= 24;

     return (finishHour * 100 + finishMinute);  
}

//given end and start time, calculates the duration in 24 hour clock (duration is always less than one day) 
int duration(int endtime, int starttime)
{
     if(endtime < starttime)
         endtime += 2400;

     int endHour = endtime / 100;
     int endMinute = endtime % 100;
     int startHour = starttime / 100;
     int startMinute = starttime % 100;

     int durationMinute = endMinute - startMinute;
     int durationHour = endHour - startHour;

     if(durationMinute < 0)
     {
        durationMinute += 60;
        durationHour--;
     }

    return (durationHour * 100 + durationMinute);

}   

测试时间.c

#include "unity.h"
#include "time.c"
setUp()
{
}
tearDown()
{
}
void firstTest()
{
    TEST_ASSERT_EQUAL_INT(1, add_time(2359, 2));
    TEST_ASSERT_EQUAL_INT(1530, add_time(1215, 315));
    TEST_ASSERT_EQUAL_INT(2215, add_time(2345, 2230));
}

int main()
{
    firstTest();
    return 0;
}

单元测试失败后通常会出现段错误的说法是不正确的。然而，当您的代码错误时，通常会出现段错误和其他错误。

您无法真正概括与特定框架或技术(在本例中为单元测试)相关的段错误。在调查错误原因之前，您所知道的只是错误发生了。

尝试在调试器中运行不正确的代码并找出段错误发生的确切位置？是在你的代码中，还是在单元测试框架中？
