## Description

`cut_add_data()` requires custom data type for complex test data. But it's not easy to write. `gcut_add_datum()` provides API to use complex test data without custom data type. It uses GType for providing complex data.

## Details

### gcut_add_datum ()

    void                gcut_add_datum                      (const gchar *name,
                                                             const gchar *first_field_name,
                                                             ...);

Adds a datum to be used in data driven test. It's convenient rather than `cut_add_data()` because you doesn't need to define a new structure for a complex test data.

e.g.:

    #include <gcutter.h>

    void data_translate (void);
    void test_translate (gconstpointer data);

    static const gchar*
    translate (gint input)
    {
       switch(input) {
       case 1:
           return "first";
       case 111:
           return "a hundred eleven";
       default:
           return "unsupported";
       }
    }

    void
    data_translate(void)
    {
        gcut_add_datum("simple data",
                       "translated", G_TYPE_STRING, "first",
                       "input", G_TYPE_INT, 1,
                       NULL);
        gcut_add_datum("complex data",
                       "translated", G_TYPE_STRING, "a hundred eleven",
                       "input", G_TYPE_INT, 111,
                       NULL);
    }

    void
    test_translate(gconstpointer data)
    {
        cut_assert_equal_string(gcut_data_get_string(data, "translated"),
                                translate(gcut_data_get_int(data, "input")));
    }
