Ctest

This is a light autotest framwork for c.

Usage

For Now, You can use it to test a simple c programming. it can not use in a huge project. And it can use to test a part of code.

For Example, my little project cregex. And i can write this test file named: Test_re.c

Notice, All the test files need to begin with Test_ and all the test functions need to begin with Test_ too.

Here is the test code:

#include "cregex.h"
#include <assert.h>
#include <stdio.h>

#define str "[a-zA-Z, ]*"

void
Test_cregex_match(void)
{
	char *string  = "Hello, Today is 2017/11/27";
	char *pattern = "^" str "([0-9]{4})/([0-9]{2})/([0-9]{2})$";

	cregex_t  reg;
	cregex_init(&reg, 10);
	assert(cregex_match(&reg, pattern, string) != -1);
	assert(reg->nmatched == 4);
	cregex_free(&reg);
	printf("pass\n");
}

void
Test_cregex_match_all(void)
{
    char *string2  = "paranormal";
    char *pattern2 = "(a.)";

	cregex_t  reg;
	cregex_init(&reg, 10);
	assert(cregex_match_all(&reg,pattern2,string2) != -1);
	assert(reg->nmatched == 4);
	cregex_free(&reg);
	printf("pass\n");
}

and the files in the src are:

$ ls
cregex.c cregex.h Test_re.c

Now, you just use the ctest to run this test just like:

$ ctest Test_re.c cregex.c
pass
pass

Use gcc ctest.c -o ctest -ldl to generate the ctest binary.

Assertion and Result

Just an experiment for Now, So it is hard to use firstly. But, I will improve that soon

Some assertion functions will add to auto test. Now, the util.h and util.c are still in progress, As a semifinished product, It only support int check, and the output will more specific. Here we go!

First, we compile a dynamic library libutil.so

$ gcc -fPIC -shared util.c -o libutil.so

If you don't have super user privilage, You should set the environment parameter CTEST_LIB_PATH by the path of libutil.so. For instant:

$ ls
libutil.so
$ pwd
/home/user/lib
$ export CTEST_LIB_PATH=/home/user/lib

if not set, the path will use the default value /usr/local/lib. This will cause open library file error. So,i recommend you use the first approach.

And now just for experiment we need to set LD_LIBRARY_PATH=. or DYLD_LIBRARY_PATH=. in Max OS. Where the path is the path of libutil.so. In MAC OS, we still need to set export DYLD_LIBRARY_PATH=/path/of/libutil.so.

If we do so, we can write this testfile Test_example.c

#include <stdio.h>
#include "util.h"

void
Test_isalnum(void *c)
{
}


void Test_isalpha (void *c)
{
    intequal(1, 2, __LINE__, __FUNCTION__, __FILE__);
}


void
   Test_iscntrl     (void *c)
{
    intequal(1, 1, __LINE__, __FUNCTION__, __FILE__);

}

Next, we just run:

$ ctest Test_example.c

It will generate this output:

Note: The output is not very pretty, And when i finish this project. It will look good than now.
