Testing

Local setup

Before you can run tests locally you must have:

• The latest tox and pip installed.

    $ sudo pip install --upgrade tox pip
  

• The Google Cloud SDK installed. You can do so with the following command:

    $ curl https://sdk.cloud.google.com | bash
  

• Most tests require you to have an active, billing-enabled project on the Google Developers Console.

• You will need a set of Service Account Credentials for your project in json form.

• Set the environment variables appropriately for your project.

    $ export GOOGLE_APPLICATION_CREDENTIALS=your-service-account-json-file
    $ export TEST_PROJECT_ID=your-project-id
    $ export TEST_BUCKET_NAME=your-bucket-name
  

If you want to run the Google App Engine tests, you will need:

• The App Engine Python SDK. You can install this with the Google Cloud SDK:

    $ gcloud components update gae-python
  

• You will need to set an additional environment variable:

    $ export GAE_PYTHONPATH=~/google-cloud-sdk/platform/google_appengine
  

Test environments

We use tox to configure multiple python environments:

• py27 contains tests for samples that run in a normal Python 2.7 environment. This is (mostly) everything outside of the appengine directory.
• gae contains tests for samples that run only in Google App Engine. This is (mostly) everything in the appengine directory.
• pep8 just runs the linter.

To run tests for a particular environment, invoke tox with the -e flag:

tox -e py27

To run one particular test suite or provide additional parameters to nose, invoke tox like this:

toxe -e py27 -- storage/tests/test_list_objects.py

Note: The gae environment can't be told to run one particular test at this time.

Adding new tests

There are a handful of common testing utilities are located under tests, see existing tests for example usage.

When adding a new top-level directory, be sure to edit .coveragerc to include it in coveralls.

To add new tests that require Google App Engine, please place them in the appengine directory if possible. If you place them elsewhere, you will need to modify tox.ini to make the environments appropriately run or ignore your test.
