pytest-cloud 1.0.2

Distributed tests planner plugin for pytest testing framework.

Splinter plugin for the py.test runner

Install pytest-cloud

pip install pytest-cloud

Features

The plugin provides an easy way of running tests amoung several test nodes (slaves). Uses the great pytest-xdist plugin for actual distributed run. When used, it will automatically detect capabilites of given node(s) and run only the number of test processes it is able to handle. If will also filter out offline nodes or nodes which were failed to respond to the capabilities aquisition call.

Supports automatic virtualenv activation on the test node so you don’t have to install python dependencies for your project on remote test nodes globally - just make sure that your virtualenv folder is inside your project folder - that’s a requirement, and then pass it’s relative path as a parameter (see below).

ATM only ssh transport is supported. So ensure that you have at least public key auth enabled to your test nodes from the master node (where py.test is executed).

Command-line options

• –cloud-node

  Node host name to run tests on. Multiple allowed.

• –cloud-chdir

  Optional relative path to be used on the remote test nodes as target folder for syncing file and run tests. Default is pytest_<username>_<current_folder_name>.

• –cloud-virtualenv-path

  Optional relative path to the virtualenv to be used on the remote test nodes.

• –cloud-mem-per-process

  Optional amount of memory roughly needed for test process, in megabytes. Will be used to calculate amount of test processes per node, getting the free memory, dividing it for the memory per process needed, and getting the minimum of that value and the number of CPU cores of the test node.

• –cloud-max-processes

  Optional maximum number of processes per test node. Overrides from above the calculated number of processes using memory and number of CPU cores.

Example

py.test tests/ --cloud-node=10.0.120.{1..40} --cloud-mem-per-process=1000 --cloud-virtualenv-path=.env/ --rsyncdir=.
