pytest-lockable 0.10.0

Description:

pytestlockable 0.10.0

pytest-lockable



pytest plugin for lockable resources.
Replacement for Jenkins lockable -plugin.
Locking is implemented using <resource-id>.pid files and is released automatically.
Resources are automatically released when pytest ends.
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",
"os": "Android"
}
]

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.
Usage:
pytest --allocation_hostname localhost -s --allocation_requirements os=Android my_test

installation
Requires: python 3.7<
pip install pytest-lockable

integrations
pytest-lockable integrates pytest-metadata - when resource is
reserved and pytest-metadata plugin are in use metadata will
be generated from resource json with resource_ -prefixes.
e.g. resource_id=<id>.
Same dictionary are also recorded to testsuite property using
record_testsuite_property -method.
Usage
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
Available resorces list
--allocation_lock_folder=<folder>, default=<os-tmp-path> allocation lockfiles folder

<requirements> can be json-string or key-value pairs. requirements have to match available resources to make allocation possible. Key-value pairs example: key=value&key2=value2
Example:
Use shared lockable resource
def test_example(lockable_resource):
""" Simple test """
print(f'Testing with resource: {lockable_resource}')

Allocate lockable resource during test with given requirements
def test_example(lockable):
""" Simple test """
with lockable.auto_lock({"my": "requirements"}) as allocation:
print(f'Testing with resource#: {allocation.resource_id}')

See example test. Usage:
cd example
pytest --allocation_hostname localhost -s --allocation_lock_folder . .
