greatest 介绍
greatest 是一个 C 语言的单元测试系统，只需要一个文件支持。示例代码：
$ cat simple.c
#include "greatest.h"
TEST x_should_equal_1() {
int x = 1;
ASSERT_EQ(1, x); /* default message */
ASSERT_EQm("yikes, x doesn't equal 1", 1, x); /* custom message */
PASS();
}
SUITE(the_suite) {
RUN_TEST(x_should_equal_1);
}
/* Add definitions that need to be in the test runner's main file. */
GREATEST_MAIN_DEFS();
int main(int argc, char **argv) {
GREATEST_MAIN_BEGIN(); /* command-line arguments, initialization. */
RUN_SUITE(the_suite);
GREATEST_MAIN_END(); /* display results */
}
$ make simple && ./simple
cc -g -Wall -Werror -pedantic simple.c -o simple
* Suite the_suite:
.
1 tests - 1 pass, 0 fail, 0 skipped (5 ticks, 0.000 sec)
Total: 1 tests (47 ticks, 0.000 sec)
Pass: 1, fail: 0, skip: 0.
