module exclusive_scheduling

pytest-xdist scheduler that runs some tests on dedicated workers.

Can significantly improve runtime by running long tests on separate workers.

class ExclusiveScheduling

Custom xdist scheduling.

Run tests from exclusive_tests.txt on separate xdist nodes.

method __init__

__init__(config: Any, log: Any) → None

Load tests from exclusive_tests.txt.

property collection_is_completed

Boolean indication initial test collection is complete.

This is a boolean indicating all initial participating nodes have finished collection. The required number of initial nodes is defined by .numnodes.

property exclusive_tests_indices

Map exclusive test names to indices.

At init tests are not collected so we do lazy initialization. Calculate at first access and use cache afterward.

property has_pending

Return True if there are pending test items

This indicates that collection has finished and nodes are still processing test items, so this can be thought of as "the scheduler is active".

property nodes

A list of all nodes in the scheduler.

property tests_finished

Return True if all tests have been executed by the nodes.

method load_exclusive_tests

load_exclusive_tests(
    filename: str = 'tests/resources/exclusive_tests.txt'
) → list[str]

Load tests from exclusive_tests.txt.

method trace

trace(*message: str) → None

Print a message with a timestamp.
