| 207 | // used with predicate assertions (ASSERT_PRED_FORMAT*, etc). | |||
| 208 | // | |||

| 229 | // Expected: true | |||
| 230 | // | |||
| 231 | // in case IsEven is a simple Boolean predicate. | |||
| 232 | // | |||

| 235 | // about half as often as positive ones in our tests), supply messages for | |||
| 236 | // both success and failure cases: | |||

| 248 | // Actual: true (8 is even) | |||
| 249 | // Expected: false | |||
| 250 | // | |||
| 251 | // NB: Predicates that support negative Boolean assertions have reduced | |||
| 252 | // performance in positive ones so be careful not to use them in tests | |||
| 253 | // that have lots (tens of thousands) of positive Boolean assertions. | |||
| 254 | // | |||

| 2010 | // 3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to | |||

| 2012 | // what the actual value is when it fails, and similarly for the | |||
| 2013 | // other comparisons. | |||
| 2014 | // | |||
| 2015 | // 4. Do not depend on the order in which {ASSERT|EXPECT}_??() | |||
