| WILL_FAIL | |
| --------- | |
| If set to true, this will invert the pass/fail flag of the test. | |
| This property can be used for tests that are expected to fail and return a | |
| non-zero return code. Note that system-level test failures such as segmentation | |
| faults or heap errors will still fail the test even if ``WILL_FALL`` is true. |
