EWC has multiple types of tests. To run a particular test suite we use Makefile targets.
Underneath, those make targets create a virtual environment, install the required Python
dependencies and use
nose Python test runner to run the tests.
Unit tests exercise small units/pieces of code (usually those are functions) and don’t require any services or 3rd party dependencies to run. Besides manipulating the state in memory, they usually have no other side affects.
In cases where a unit you are testing requires a service to run, you should use the
library to mock the service and the result.
Note: Currently some of the unit tests require database (MongoDB) and message bus (RabbitMQ) to run. We are in process of moving those tests to the integration test suite.
Unit tests are located in
Integration tests exercise small pieces of code which require some EWC services such as a database and message bus to run. Usually they have side affects (e.g. changing the state in the db, etc.).
Integration tests are located in
End-to-end tests exercise the system as a whole, and require all the EWC services and dependencies (database, message bus, etc.) to run.
Usually they exercise the API and the system using the CLI and/or the Python API client.
Running all Tests¶
To run all tests, run the following command:

To run all integration tests, run the following command:
Running all Tests in a Test File¶
To run all the tests located in a single test file, move to the root of the repository and run the following command:
nosetests --nocapture <path to the test file>
nosetests --nocapture st2reactor/tests/unit/test_enforce.py
--nocapture flag tells the nose test runner to directly output any stdout and stderr
generated during the test execution instead of capturing and ignoring it.
