In this particular system the deployment does not support the 'onos' SDN -Controller Test Case; for example. - -**Important** If you use the command 'functest tier run <tier_name>', then the -Functest CLI utility will call **all valid Test Cases**, which belong to the -specified Test Tier, as relevant to scenarios deployed to the SUT environment. -Thus, the Functest CLI utility calculates automatically which tests can be -executed and which cannot, given the environment variable **DEPLOY_SCENARIO**, -which is passed in to the Functest docker container. - -Currently, the Functest CLI command 'functest testcase run <testcase_name>', supports -two possibilities:: - - * Run a single Test Case, specified by a valid choice of <testcase_name> - * Run ALL test Test Cases (for all Tiers) by specifying <testcase_name> = 'all' - -Functest includes a cleaning mechanism in order to remove all the OpenStack -resources except those present before running any test. The script -*$REPOS_DIR/functest/functest/utils/generate_defaults.py* is called once when setting up -the Functest environment (i.e. CLI command 'functest env prepare') to snapshot -all the OpenStack resources (images, networks, volumes, security groups, tenants, -users) so that an eventual cleanup does not remove any of these defaults. - -The script **clean_openstack.py** which is located in -*$REPOS_DIR/functest/functest/utils/* is normally called after a test execution. It is -in charge of cleaning the OpenStack resources that are not specified in the -defaults file generated previously which is stored in -*/home/opnfv/functest/conf/os_defaults.yaml* in the Functest docker container. - -It is important to mention that if there are new OpenStack resources created -manually after preparing the Functest environment, they will be removed, unless -you use the special method of invoking the test case with specific suppression -of clean up. (See the `Troubleshooting`_ section). - -The reason to include this cleanup meachanism in Functest is because some -test suites such as Tempest or Rally create a lot of resources (users, -tenants, networks, volumes etc.) that are not always properly cleaned, so this -function has been set to keep the system as clean as it was before a -full Functest execution. - -Although the Functest CLI provides an easy way to run any test, it is possible to -do a direct call to the desired test script. For example: - - python $REPOS_DIR/functest/functest/opnfv_tests/OpenStack/vPing/vPing_ssh.py -d - - -Automated testing ------------------ - -As mentioned previously, the Functest Docker container preparation as well as -invocation of Test Cases can be called within the container from the Jenkins CI -system. There are 3 jobs that automate the whole process. The first job runs all -the tests referenced in the daily loop (i.e. that must been run daily), the second -job runs the tests referenced in the weekly loop (usually long duration tests run -once a week maximum) and the third job allows testing test suite by test suite specifying -the test suite name. The user may also use either of these Jenkins jobs to execute -the desired test suites. - -One of the most challenging task in the Danube release consists -in dealing with lots of scenarios and installers. Thus, when the tests are -automatically started from CI, a basic algorithm has been created in order to -detect whether a given test is runnable or not on the given scenario. -Some Functest test suites cannot be systematically run (e.g. ODL suite can not -be run on an ONOS scenario). The daily/weekly notion has been introduces in -Colorado in order to save CI time and avoid running systematically -long duration tests. It was not used in Colorado due to CI resource shortage. -The mechanism remains however as part of the CI evolution. - -CI provides some useful information passed to the container as environment -variables: - - * Installer (apex|compass|daisy|fuel|joid), stored in INSTALLER_TYPE - * Installer IP of the engine or VM running the actual deployment, stored in INSTALLER_IP - * The scenario [controller]-[feature]-[mode], stored in DEPLOY_SCENARIO with - - * controller = (odl|onos|ocl|nosdn) - * feature = (ovs(dpdk)|kvm|sfc|bgpvpn|multisites) - * mode = (ha|noha) - -The constraints per test case are defined in the Functest configuration file -*/home/opnfv/repos/functest/functest/ci/testcases.yaml*:: - - tiers: - - - name: healthcheck - order: 0 - ci_loop: '(daily)|(weekly)' - description : >- - First tier to be executed to verify the basic - operations in the VIM. - testcases: - - - name: healthcheck - criteria: 'status == "PASS"' - blocking: true - description: >- - This test case verifies the basic OpenStack services like - Keystone, Glance, Cinder, Neutron and Nova. - - dependencies: - installer: '' - scenario: '' - - - - name: smoke - order: 1 - ci_loop: '(daily)|(weekly)' - description : >- - Set of basic Functional tests to validate the OpenStack deployment. - testcases: - - - name: vping_ssh - criteria: 'status == "PASS"' - blocking: true - description: >- - This test case verifies: 1) SSH to an instance using floating - IPs over the public network. 2) Connectivity between 2 instances - over a private network. - dependencies: - installer: '' - scenario: '^((?!bgpvpn|odl_l3).)*$' - run: - module: 'functest.opnfv_tests.openstack.vping.vping_ssh' - class: 'VPingSSH' - .... - -We may distinguish 2 levels in the test case description: - * Tier level - * Test case level - -At the tier level, we define the following parameters: - - * ci_loop: indicate if in automated mode, the test case must be run in daily and/or weekly jobs - * description: a high level view of the test case - -For a given test case we defined: - * the name of the test case - * the criteria (experimental): a criteria used to declare the test case as PASS or FAIL - * blocking: if set to true, if the test is failed, the execution of the following tests is canceled - * the description of the test case - * the dependencies: a combination of 2 regex on the scenario and the installer name - * run: In Danube we introduced the notion of abstract class in order to harmonize the way to run internal, feature or vnf tests - -For further details on abstraction classes, see developper guide. - -Additional parameters have been added in the desription in the Database. -The target is to use the configuration stored in the Database and consider the -local file as backup if the Database is not reachable. -The additional fields related to a test case are: - * trust: we introduced this notion to put in place a mechanism of scenario promotion. - * Version: it indicates since which version you can run this test - * domains: the main domain covered by the test suite - * tags: a list of tags related to the test suite - -The order of execution is the one defined in the file if all test cases are selected. - -In CI daily job the tests are executed in the following order: - - 1) healthcheck (blocking) - 2) smoke: both vPings are blocking - 3) Feature project tests cases - -In CI weekly job we add 2 tiers: - - 4) VNFs (vIMS) - 5) Components (Rally and Tempest long duration suites) - -As explained before, at the end of an automated execution, the OpenStack resources -might be eventually removed. -Please note that a system snapshot is taken before any test case execution. - -This testcase.yaml file is used for CI, for the CLI and for the automatic reporting. |
