| 1842 | // {ASSERT|EXPECT}_TRUE() macro to assert that two objects are |
| 1843 | // equal. |
| 1844 | // |
| 1845 | // 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on |
| 1846 | // pointers (in particular, C strings). Therefore, if you use it |
| 1847 | // with two C strings, you are testing how their locations in memory |
| 1848 | // are related, not how their content is related. To compare two C |
| 1849 | // strings by content, use {ASSERT|EXPECT}_STR*(). |
| 1850 | // |
| 1851 | // 3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to |
| 1852 | // {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you |
