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.

Test container

The scripts can be executed from a containerized environment. As part of the contrail software the test containers are also being built and posted @ https://hub.docker.com/r/opencontrailnightly/contrail-test-test/

Build test container

Test container is split into base and test containers where in base has sku and orchestrator independent packages like testr, chrome, wget, git etal and test container has orchestrator and sku specific packages on top of base.

One can also custom build base and test containers

To build base test container

    $> ./build-container.sh base -h
       Build base container

       Usage: ./build-container.sh base
         -h|--help                     Print help message
         --registry-server REGISTRY_SERVER Docker registry hosting the base test container, specify if the image needs to be pushed
         --tag             TAG           Docker container tag, default to sku
    $> ./build-container.sh base --registry-server opencontrailnightly/ --tag ocata-bld-1

To build test container

    $> ./build-container.sh test -h
       Build test container

       Usage: ./build-container.sh test [OPTIONS]

         -h|--help                     Print help message
         --tag           TAG           Docker container tag, default to sku
         --base-tag      BASE_TAG      Specify contrail-base-test container tag to use. Defaults to 'latest'.
         --sku           SKU           Openstack version. Defaults to ocata
         --contrail-repo CONTRAIL_REPO Contrail Repository, mandatory.
         --registry-server REGISTRY_SERVER Docker registry hosting the base test container, Defaults to docker.io/opencontrail
         --post          POST          Upload the test container to the registy-server, if specified
    $> ./build-container.sh test --tag ocata-bld-1 --base-tag ocata-bld-1 --sku ocata --package-url http://path/to/contrail-install-packages.rpm --contrail-repo http://path/to/contrail/repo/bld-1 --registry-server opencontrailnightly

Running Tests

• Create a test input file as per https://github.com/Juniper/contrail-test/blob/master/contrail_test_input.yaml.sample
• Download testrunner.sh script to the host where the test container will run
• Pull the test container image from dockerhub
• Execute the testrunner.sh script

    $> wget https://github.com/tungstenfabric/tf-test/raw/master/testrunner.sh
    $> docker pull opencontrailnightly/contrail-test-test:ocata-bld-1
    $> ./testrunner.sh run -P /path/to/contrail_test_input.yaml contrail-test-test:ocata-bld-1

You can find more detailed information about running tests @ (https://github.com/Juniper/contrail-test/wiki/How-to-use-contrail-test-container#sample-testrunnersh-commands)

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.
