## Description

To check that your program works as you expect, you use `cut_assert_XXX()` where you want to check expected value is got.

e.g.:

    1

    cut_assert_equal_int(3, 1 + 2);

## Functions

### cut_assert ()

    cut_assert(string);

    1
    2
    3

    MyObject *object;
    object = my_object_new();
    cut_assert(object, cut_message("my_object_new() should not be failed"));

#### Parameters

expression | the expression to be checked. |
