Murano automated tests description

This page describes automated tests for a Murano project:

  • where tests are located
  • how they are run
  • how to execute tests on a local machine
  • how to find the root of problems with FAILed tests

Murano continuous integration service

Murano project has separate CI server, which runs tests for all commits and verifies that new code does not break anything.

Murano CI uses OpenStack QA cloud for testing infrastructure.

Murano CI url: https://murano-ci.mirantis.com/jenkins/ Anyone can login to that server, using launchpad credentials.

There you can find each job for each repository: one for murano and another one for murano-dashboard.

  • gate-murano-dashboard-ubuntu\* verifies each commit to the murano-dashboard repository
  • gate-murano-ubuntu\* verifies each commit to the murano repository

Other jobs allow one to build and test Murano documentation and to perform other useful work to support the Murano CI infrastructure. All jobs are run following a fresh installation of the operating system and all components are installed on each run.

UI tests

The Murano project has a web user interface and all possible user scenarios should be tested. All UI tests are located at https://git.openstack.org/cgit/openstack/murano-dashboard/tree/muranodashboard/tests/functional.

Automated tests for the Murano web UI are written in Python using the special Selenium library. This library is used to automate web browser interactions with Python. See official Selenium documentation for details.

Prerequisites:

  • Install the Python module called nose using either the easy_install nose or pip install nose command. This will install the nose libraries, as well as the nosetests script, which you can use to automatically discover and run tests.

  • Install external Python libraries, which are required for the Murano web UI tests: testtools and selenium.

  • Verify that you have one of the following web browsers installed:

    • Mozilla Firefox 46.0

      Note

      If you do not have Firefox package out of the box, install and remove it. Otherwise, you will need to install dependant libraries manually. To downgrade Firefox:

      apt-get remove firefox
wget https://ftp.mozilla.org/pub/firefox/releases/46.0/linux-x86_64/en-US/firefox-46.0.tar.bz2
tar -xjf firefox-46.0.tar.bz2
rm -rf /opt/firefox
mv firefox /opt/firefox46
ln -s /opt/firefox46/firefox /usr/bin/firefox

    • Google Chrome

  • To run the tests on a remote server, configure the remote X server. Use VNC Software to see the test results in real-time.

    1. Specify the display environment variable:

      $DISPLAY=: <value>

    2. Configure remote X server and VNC Software by typing:

      apt-get install xvfb xfonts-100dpi xfonts-75dpi xfonts-cyrillic xorg dbus-x11
"Xvfb -fp "/usr/share/fonts/X11/misc/" :$DISPLAY -screen 0 "1280x1024x16" &"
apt-get install --yes x11vnc
x11vnc -bg -forever -nopw -display :$DISPLAY -ncache 10
sudo iptables -I INPUT 1 -p tcp --dport 5900 -j ACCEPT

Download and run tests

To download and run the tests:

  1. Verify that all additional components has been installed.

  2. Clone the murano-dashboard git repository:

    git clone git://git.openstack.org/openstack/murano-dashboard

  3. Change the default settings:

    1. Specify the Murano Repository URL variable for Horizon local settings in murano_dashboard/muranodashboard/local/local_settings.d/_50_murano.py:

      MURANO_REPO_URL = 'http://localhost:8099'

    2. Copy muranodashboard/tests/functional/config/config.conf.sample to config.conf.

    3. Set appropriate URLs and credentials for your OpenStack lab. Only Administrator user credentials are appropriate.

      [murano]

horizon_url = http://localhost/dashboard
murano_url = http://localhost:8082
user = ***
password = ***
tenant = ***
keystone_url = http://localhost:5000/v3

All tests are kept in sanity_check.py and divided into 10 test suites:

  • TestSuiteSmoke - verification of Murano panels; checks that they can be open without errors.
  • TestSuiteEnvironment - verification of all operations with environment are finished successfully.
  • TestSuiteImage - verification of operations with images.
  • TestSuiteFields - verification of custom fields validators.
  • TestSuitePackages - verification of operations with Murano packages.
  • TestSuiteApplications - verification of Application Catalog page and of application creation process.
  • TestSuiteAppsPagination - verification of apps pagination in case of many applications installed.
  • TestSuiteRepository - verification of importing packages and bundles.
  • TestSuitePackageCategory - verification of main operations with categories.
  • TestSuiteCategoriesPagination - verification of categories pagination in case of many categories created.
  • TestSuiteMultipleEnvironments - verification of ability to apply action to multiple environments.

To run the tests follow these instructions:

  • To run all tests:
nosetests sanity_check.py
  • To run a single suite:
nosetests sanity_check.py:<test suite name>
  • To run a single test:
nosetests sanity_check.py:<test suite name>.<test name>

In case of successful execution, you should see something like this:

.........................
Ran 34 tests in 1.440s
OK

In case of failure, the folder with screenshots of the last operation of tests that finished with errors would be created. It is located in muranodashboard/tests/functional folder.

There are also a number of command line options that can be used to control the test execution and generated outputs. For more details about nosetests, type:

nosetests -h

Tempest tests

All Murano services have tempest-based automated tests, which verify API interfaces and deployment scenarios. Tempest tests for Murano are located at https://git.openstack.org/cgit/openstack/murano/tree/murano/tests/functional.

The following Python files contain basic test suites for different Murano components.

API tests

Murano API tests are run on the devstack gate located at https://git.openstack.org/cgit/openstack/murano/tree/murano/tests/functional/api.

  • test_murano_envs.py contains test suite with actions on murano environments (create, delete, get, and others).
  • test_murano_sessions.py contains test suite with actions on murano sessions (create, delete, get, and others).
  • test_murano_services.py contains test suite with actions on murano services (create, delete, get, and others).
  • test_murano_repository.py contains test suite with actions on murano package repository.

Engine tests

Murano Engine Tests are run on murano-ci at https://git.openstack.org/cgit/openstack/murano/tree/murano/tests/functional/engine:

  • base.py contains base test class and tests with actions on deploy Murano services such as Telnet and Apache.

Command-line interface tests

Murano CLI tests are currently in the middle of creation. The current scope is read-only operations on a cloud that are hard to test through unit tests. All tests have description and execution steps in their docstrings.
