Overview

The Contrail Test repository contains the test code for validating the Contrail infrastructure. The code is organized into fixtures , scripts and serial_scripts.

Testcases under scripts folder are independent of each other and can be run in parallel. Testcases under serial_scripts can have cluster-wide impact and MUST be run only one at a time.

run_tests.sh lets you run these tests as well. Take a look at this .

fixtures

Contains high level fixtures for creating projects, virtual networks, virtual machines, floating ips, policies, security-groups, service instances, VPCs, VDNS etc. and validate these objects against Contrail components like Contrail API Server, Control nodes, Virtual Routers. The fixtures provide verify_on_setup() and verify_on_cleanup() methods to achieve this. They also provide some commonly used methods to work with these objects. Examples include:

  • To run commands on a VM and verify connectivity to it
  • Traffic send/receive methods using tools like scapy/netperf
  • Policy rules validation with traffic
  • Perform tcp/icmp/ssh/scp/tftp validations on the VM
  • Flow verification for traffic
  • Analytics data validation

scripts, serial_scripts

Test scripts at a per-feature level. Sub-folders are created for the features. The test scripts can be run on any of the config nodes in the Contrail cluster.

Initialization

Install git on the node

    $> apt-get install git 
or ::
    $> yum install git

Checkout the corresponding branch that the cluster is running ("master","R1.05", "R1.04" etc.)

    $> git clone git@github.com:Juniper/contrail-test.git
    $> cd contrail-test
    $> git checkout R1.05

Populate the path of this test repo in env.test_repo_dir in testbed.py (typically /opt/contrail/utils/fabfile/testbeds/testbed.py). Refer to sanity_params.ini.sample for more options. Populate the path to the images in configs/images.cfg.

##Running Tests Run the 'run_sanity' task in fab:

    $> cd /opt/contrail/utils
    $> # Run Sanity test
    $> fab run_sanity
    $> # Run CI Sanity
    $> fab run_sanity:ci_sanity

Run fab run_sanity:help to view help on running individual tests and other regressions.

The run_sanity task installs the python modules required for running tests, autogenerates sanity_params.ini and sanity_testbed.json and sources them for the tests. sanity_testbed.json contains the Contrail cluster topology information.

To setup fab and learn about testbed.py, please refer to [Contrail Documentation ] (https://www.juniper.net/techpubs/en_US/contrail1.0/topics/task/installation/testbed-file-vnc.html).

The log files and any html report of the entire run will be created in contrail-test/logs folder.

You can find more detailed information of the [WIKI page] (https://github.com/Juniper/contrail-test/wiki/Running-Tests).

Usage:

  fab run_sanity
  fab run_sanity:ci_sanity

Filing Bugs

Use launchpad http://bugs.launchpad.net/juniperopenstack to describe new bugs.

It will be useful to include the test run log file.

For post-analysis of a cluster, a fab task attach_logs_cores can collect the logs and cassandra logs.
