A very simple header file for writing simple unit tests in C++.

Existing C++ UT tools like GTest are very strong, but not lightweight enough. Sometimes I just write very simple codes and would like to test them. I don't want to install another module, or to use CMake. I just want a simple g++ test.cpp && ./a.out and hope to see everything just works.

#include "gooooloo_test.h"

GOOOOLOO_TEST(good_case)
{
    GOOOOLOO_ASSERT_EQUAL_INT(42, 42);
    return 0;
}

int main() {
    return 0;
}

• Just #include "gooooloo_test.h" in cpp, then you can write your UTs.
• Adding a case is very easy, just GOOOOLOO_TEST(your_unique_test_case_name) and write your case. You don't need to call it explicitly anywhere else!

• Need to write { in the next line after ther GOOOOLOO_TEST(case_name) line.
• Need to explict write return 0; in every case.
• Test case name should not conflict with existing symbles. For example, if you write a function named foo, and would like to test, then you can not to write GOOOOLOO_TEST(foo). You have to modify the case name, such as GOOOOLOO_TEST(test_foo).
• Very limited assert functions. This can be improved gradually.
