How to have tests on multiple c files?

[stefano-p]

I was evaluating this framework and found that is seems not possible to build multiple c test files. So do I have to put all tests in one single module?

This file alone ( test_all.c) compiles and run correctly.

test_all.c

#define CESTER_NO_MAIN
#include <exotic/cester.h>

CESTER_TEST(test1, test_instance,
            cester_assert_equal(NULL, NULL);
)

CESTER_TEST(test_two, test_instance,
    cester_assert_ptr_equal(test_instance, NULL);    
)

CESTER_TEST(test_three, test_instance,
    cester_assert_short_eq(1, 1);    
)

CESTER_BODY(
int main(int argc, char** argv) {
        return CESTER_RUN_ALL_TESTS(argc, argv);
}
)

But as I add a new one (test_my_module1.c) I get some strange linker errors saying that there are:

• multiple definition of `superTestInstance';
• multiple definition of `default_color';
• multiple definition of `hConsole';

I also had to define CESTER_NO_MAIN and CESTER_NO_SIGNAL in order to lower the number of "multiple definition" errors.

test_my_module1.c

#define CESTER_NO_MAIN
#define CESTER_NO_SIGNAL
#include <exotic/cester.h>

CESTER_TEST(test4, test_instance,
            cester_assert_equal(NULL, NULL);
)

Is it possible to spread tests accross multiple c files? How?

Hello Stefano

It currently not possible to compile multiple source file. I have not have a scenario to compile multiple test file. You are the first to point that out, I'll check today to try compile multiple source, if it possible I'll add the feature.

I hope by multiple source compilation you meant.

gcc test_my_module1.c test_all.c -I

Yes @Thecarisma, that is what I meant. It would be a very important feature that all other framework I have tested so far already have. All my projects would require separate c test files, each one dedicated to a specific module. Putting all tests in one c file would not be good, for clarity and maintenance reasons. In principle, each module would have its associated test file. Then all tests are run in one shot.

Hello, is there any progress for supporting multiple test files?

@Thecarisma, I agree with @stefano-p that test frameworks should support breaking tests out across multiple files, in the same way that source code can be broken across multiple files. I created #71 from this question.
