Testing Nodepool

A Quickstart

This is designed to be enough information for you to run your first tests on an Ubuntu 16.04 (or later) host.

Install pip:

sudo apt-get install python3-pip

More information on pip here:

Use pip to install tox:

sudo pip3 install tox

A running zookeeper is required to execute tests.

Install zookeeper:

sudo apt-get install zookeeperd

Start zookeeper:

sudo service zookeeper start

Run The Tests

Navigate to the project's root directory and execute:


Note: completing this command may take a long time (depends on system resources) also, you might not see any output until tox is complete.

Information about tox can be found here:

Run The Tests in One Environment

Tox will run your entire test suite in the environments specified in the project tox.ini:


envlist = <list of available environments>

To run the test suite in just one of the environments in envlist execute:

tox -e <env>

so for example, run the test suite in py35:

tox -e py35

Run One Test

To run individual tests with tox:

tox -e <env> --

For example, to run a single Nodepool test:

tox -e py35 -- nodepool.tests.unit.test_launcher.TestLauncher.test_node_assignment

To run one test in the foreground (after previously having run tox to set up the virtualenv):

.tox/py35/bin/stestr run nodepool.tests.unit.test_launcher.TestLauncher.test_node_assignment

List Failing Tests

.tox/py35/bin/activate stestr failing --list

Hanging Tests

The following will run each test in turn and print the name of the test as it is run:

. .tox/py35/bin/activate
stestr run

You can compare the output of that to:

python -m discover --list
