11. Testing openPLM

11.1. Overview

openPLM uses Django’s testing framework. Most tests are unit tests.

11.2. Running tests

11.2.1. Dependencies

Tests depend on lxml (package python-lxml). Moreover the subversion – Application pour les dépôts Subversion and gdoc – Application Google Document are tested, so theirs dependencies must be installed (it is not necessary to configure an OAuth account).

11.2.2. Settings

openPLM ships with a settings file named settings_tests.py. Notable changes compared to a standard settings file are:

• the database is a sqlite3 database
• files are saved into a tempory folder
• the xapian index is saved in an in-memory database
• celery tasks are synchronously run
• south is not enabled
• some testing purpose applications are enabled
• loaded templates are cached (note that this setting may be enabled in production)

11.2.3. Running all tests

To run all tests:

• cd /path/to/openPLM
• ./manage.py test --settings=settings_tests

Note that some subversion tests require an access to openplm.org (they do something similar to svn log).

11.2.4. Running a specific test

It is possible to only test a specific application:

• ./manage.py test plmapp --settings=settings_tests
• ./manage.py test pdfgen --settings=settings_tests

It is also possible to run a specific test case:

• ./manage.py test plmapp.GroupControllerTestCase --settings=settings_tests

It is also possible to run a single test:

• ./manage.py test plmapp.GroupControllerTestCase.test_create --settings=settings_tests

11.2.5. Testing document3D app

By default, document3D is not tested since it depends on PythonOCC which is not packaged on all distributions. To test document3D, the environment variable openPLM3D must be set to enabled. For example, the command openPLM3D="enabled" ./manage.py test --settings=settings_tests runs all tests, including document3D’s tests.

11.3. Code coverage

openPLM ships with a script named ./bin/run_coverage.sh. This script runs all tests with coverage. By default, this script produces an html report into the coverage_report directory. It is possible to produce an XML output by setting the environment variable TEST_OUTPUT to xml. This output produces a file in tests_results in a format compatible with Cobertura.

11.4. Tasks (celery)

The file settings_tests.py has special celery settings:

• An in-memory broker is used
• All tasks are run synchronously so that it is easier to check their effects. This implies that some possible concurrency bugs can not be detected.
• Exceptions are propagated.
