1. IntroductionCutest is a tiny C-Language Unit test box, one of the most concise test frameworks I've seen so far, with only 2 files, cutest.c and CuTest.h, all of which add up to less than 1000 lines of code. Perfectly formed, test construction, test management, test statements are all included.2, cutest analysis2.1 AssertionsWhether a test case is implemented by falling into code is a comparison between the test value and the expected value, which is used to assert.#defineCuassertstrequals (T
