pytest-lockable 0.2.1

lockable resource plugin for pytest

pytest-lockable

pytest plugin for lockable resources.

Replacement for Jenkins lockable -plugin. Locking is implemented using <resource.id>.lock files.

Resources are described in json file as array of objects. Each object has some mandatory fields but can contains any other as well. Required fields are: id, online, hostname-

Example resources.json

[
  {
    "id": "1234",
    "online": true,
    "hostname": "localhost"
  }
]

id should be unique for each resources. online describes if resource are available for allocator. Set this false if you don't want to allocate resource. hostname is used to select suitable resource by running host.

installation

Requires: python 3.7<

pip install pytest-lockable

conftest.py:

pytest_plugins = ("lockable.plugin",)

Custom options:

--allocation_hostname=<hostname>, default=<os-hostname>  Allocation host
--allocation_requirements=<requirements>                 Resource requirements to be allocate
--allocation_timeout=<timeout>, default=10               Allocation timeout in seconds
--allocation_resource_list_file=<filename>, default=resources.json

cd example
pytest --allocation_hostname localhost -s --allocation_lock_folder .  .
