| RESOURCE_LOCK | |
| ------------- | |
| Specify a list of resources that are locked by this test. | |
| If multiple tests specify the same resource lock, they are guaranteed | |
| not to run concurrently. | |
| See also :prop_test:`FIXTURES_REQUIRED` if the resource requires any setup or | |
| cleanup steps. | |
| Both the :prop_test:`RESOURCE_GROUPS` and ``RESOURCE_LOCK`` properties serve | |
| similar purposes, but they are distinct and orthogonal. Resources specified by | |
| :prop_test:`RESOURCE_GROUPS` do not affect ``RESOURCE_LOCK``, and vice versa. | |
| Whereas ``RESOURCE_LOCK`` is a simpler property that is used for locking one | |
| global resource, :prop_test:`RESOURCE_GROUPS` is a more advanced property | |
| that allows multiple tests to simultaneously use multiple resources of the | |
| same type, specifying their requirements in a fine-grained manner. | |
