Running the Test Suite

virtualenv

It is recommended that you develop and run tests from within the confines of a virtualenv. If you have virtualenv installed, create the new environment by executing:

$> virtualenv neo4django

Once created, clone a local copy of the neo4django source:

$> cd neo4django
$> git clone https://github.com/scholrly/neo4django src/neo4django

After you have a virtualenv created, you must activate it:

$> source <venv_path>/bin/activate

Neo4j Test Instance

The test suite requires that Neo4j be running, and that you have the cleandb extension installed at localhost:7474/cleandb. You must download the appropriate cleandb version that matches the version of Neo4j you have running. Place the plugin jar in <NEO4J_PATH>/plugins and edit <NEO4J_PATH>/conf/neo4j-server.properties to include the following:

org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.server.extension.test.delete=/cleandb
org.neo4j.server.thirdparty.delete.key=supersecretdebugkey!

The first line represents the URL endpoint for invoking cleandb, and the second line is the password to use the cleandb extension. You can change these values to whatever makes most sense to you, but keep in mind that the test suite currently expects /cleandb and supersecretdebugkey! for both the URL and password respectively. If you choose to use different values, you will need to edit neo4django/tests/test_settings.py to reflect your local changes.

If you are testing on a linux platform, you may also easily spin up a local test Neo4j instance by using the packaged install_local_neo4j.bash script. This script will retrieve a specified version of the community package of Neo4j and install it into a lib folder in your current working directory. The script will also retrieve and install the cleandb extension and install it as well.

By default, running install_local_neo4j.bash with no arguments will install version 1.8.2, as this is the oldest version run for Travis CI builds and supported by neo4django. If you would like to test another version, install_local_neo4j.bash accepts a version number as an argument. Currently, Travis CI builds are run against 1.8.2 and 1.9.RC1 versions of Neo4j; tests against 1.7.2 are run, but expected to fail. Once installed, start the local Neo4j instance via lib/neo4j-community-<VERSION>/bin/neo4j start. Similarly, you can stop the local instance via lib/neo4j-community-<VERSION>bin/neo4j stop.

Running Tests

If you are working withing an virtualenv (and you should be), activate your venv (see above) and use pip to install both the core requirements and the requirements for running tests:

$> pip install -r requirements.txt -r test_requirements.txt

Since testing involves working with django, you will need to export an environment variable for the included test django settings:

$> export DJANGO_SETTINGS_MODULE=neo4django.tests.test_settings

Now you can run the test suite. All tests in the neo4django test suite are expected to be run with nose and use a plugin for ensuring that regression tests pass (both are installed for you if you pip install the test requirements). To run the test suite, simply issue the following:

$> cd <path_to>/neo4django
$> nosetests --with-regression

This may give you some output about failing tests, but you should be most interesting in the final output in which a report is given about tests passing or failing regression tests. Note, that ANY changeset that fails regression tests will be denied a pull.
