运行可执行文件 test 可以实施测试.
$ ./test    <-- 默认执行, 没有参数
test.c:34: error: Failure in TEST(sample, ret_int_failed)
expected <3>
but was  <4>
difference starts at position 0 at: <          4         >
^
..
Errors (1 failures, 2 tests, 2 ran, 2 checks, 0 ignored, 0 filtered out, 1 ms)
=================================================================================
$ ./test -c   <-- -c 执行结果加上颜色 (成功绿色, 失败红色)
test.c:34: error: Failure in TEST(sample, ret_int_failed)
expected <3>
but was  <4>
difference starts at position 0 at: <          4         >
^
..
Errors (1 failures, 2 tests, 2 ran, 2 checks, 0 ignored, 0 filtered out, 1 ms) <-- bash中显示红色
=================================================================================
$ ./test -v  <-- -v 显示更为详细的信息
TEST(sample, ret_int_failed)
test.c:34: error: Failure in TEST(sample, ret_int_failed)

- 1 ms
TEST(sample, ret_int_success) - 0 ms
Errors (1 failures, 2 tests, 2 ran, 2 checks, 0 ignored, 0 filtered out, 1 ms)
=================================================================================
$ ./test -r 2   <-- -r 指定测试执行的次数, 这里把测试重复执行2遍
Test run 1 of 2
test.c:34: error: Failure in TEST(sample, ret_int_failed)
expected <3>

Errors (1 failures, 2 tests, 2 ran, 2 checks, 0 ignored, 0 filtered out, 1 ms)
=================================================================================
$ ./test -g sample    <-- -g 指定 TEST_GROUP, 本例其实只有一个 TEST_GROUP sample
test.c:34: error: Failure in TEST(sample, ret_int_failed)
expected <3>
but was  <4>

Errors (1 failures, 2 tests, 2 ran, 2 checks, 0 ignored, 0 filtered out, 1 ms)
=================================================================================
$ ./test -n ret_int_success    <-- -s 指定执行其中一个 TEST, 名称为 ret_int_success
.
OK (2 tests, 1 ran, 1 checks, 0 ignored, 1 filtered out, 0 ms)
=================================================================================
$ ./test -v -n ret_int_success  <-- 参数也可以搭配使用
TEST(sample, ret_int_success) - 0 ms
OK (2 tests, 1 ran, 1 checks, 0 ignored, 1 filtered out, 0 ms)
  2.6 补充: setup and teardown
  上面 test.c 文件中 TEST_GROUP(sample) 中的代码是空的, 其实 CPPUTest 中内置了 2 个调用 setup 和 teardown.
  在 TEST_GROUP 中实现这2个函数之后, 每个属于这个 TEST_GROUP 的 TEST 在执行之前都会调用 setup, 执行之后会调用 teardown.
  修改 test.c 中的 TEST_GROUP 如下:
/* 定义个 TEST_GROUP, 名称为 sample */
TEST_GROUP(sample)
{
void setup()
{
printf ("测试开始...... ");
}
void teardown()
{
printf ("测试结束...... ");
}
};
  重新执行测试: (每个测试之前, 之后都多了上面的打印信息)
