| michael@0 | 35 | // This sample shows how to write a more complex unit test for a class |
| michael@0 | 36 | // that has multiple member functions. |
| michael@0 | 37 | // |
| michael@0 | 38 | // Usually, it's a good idea to have one test for each method in your |
| michael@0 | 39 | // class. You don't have to do that exactly, but it helps to keep |
| michael@0 | 40 | // your tests organized. You may also throw in additional tests as |
| michael@0 | 41 | // needed. |

| michael@0 | 46 | // In this example, we test the MyString class (a simple string). |
| michael@0 | 47 | |
| michael@0 | 48 | // Tests the default c'tor. |
| michael@0 | 49 | TEST(MyString, DefaultConstructor) { |
| michael@0 | 50 | const MyString s; |
| michael@0 | 51 | |
| michael@0 | 52 | // Asserts that s.c_string() returns NULL. |
| michael@0 | 53 | // |
| michael@0 | 54 | // <TechnicalDetails> |
| michael@0 | 55 | // |
| michael@0 | 56 | // If we write NULL instead of |
| michael@0 | 57 | // |
| michael@0 | 58 | // static_cast<const char *>(NULL) |
| michael@0 | 59 | // |
| michael@0 | 60 | // in this assertion, it will generate a warning on gcc 3.4. The |
| michael@0 | 61 | // reason is that EXPECT_EQ needs to know the types of its |
| michael@0 | 62 | // arguments in order to print them when it fails. Since NULL is |
| michael@0 | 63 | // #defined as 0, the compiler will use the formatter function for |
| michael@0 | 64 | // int to print it. However, gcc thinks that NULL should be used as |
| michael@0 | 65 | // a pointer, not an int, and therefore complains. |
| michael@0 | 66 | // |
| michael@0 | 67 | // The root of the problem is C++'s lack of distinction between the |
| michael@0 | 68 | // integer number 0 and the null pointer constant. Unfortunately, |
| michael@0 | 69 | // we have to live with this fact. |
