Hello,
I am sorry if this discussion is a duplicate of
this.
I am trying to generate a coverage report after performing tests with Unity. The files I have are very basic:
Source file
#include "MyExampleHeader.h"
int8_t AverageThreeBytes(int8_t a, int8_t b, int8_t c)
{
return (int8_t)(((int16_t)a + (int16_t)b + (int16_t)c) / 3);
}
int8_t FindMaximum(int8_t a, int8_t b, int8_t c)
{
uint8_t tmax = a;
if (tmax < b)
{
tmax = b;
}
if (tmax < c)
{
tmax = c;
}
return tmax;
}
Test file
#include "C:\Projects\CUnitTests\Unity-master\src\unity.h"
#include "MyExampleHeader.h"
void setUp(void)
{
}
void tearDown(void)
{
}
void test_FindMaximum(void)
{
TEST_ASSERT_EQUAL_HEX8(50, FindMaximum(20, 30, 50));
}
int main(void)
{
UNITY_BEGIN();
RUN_TEST(test_FindMaximum);
return UNITY_END();
}
I compile the two using MSVC2015 in the command line:
C:\Projects\CUnitTests\Files\Project1\Project1>cl /EHsc TestExample.c Source.c C
:\Projects\CUnitTests\Unity-master\src\unity.c

/out:TestExample.exe
TestExample.obj
Source.obj
unity.obj
After running OpenCppCoverage from the command line, I get an empty HTML report.
The output also has some peculiar lines:

I can see that the .exe is tested, however, I do not understand why are the dlls tested, why it cannot find the program pdb and why the report is empty. Any suggestions will be greatly appreciated.
Thanks
