Version bumping
-===============
+---------------
This project follows semver. When changes are made, the versions are in:
3) ``container-tag.yaml``
-4) ``integration_tests/a1mediator/values.yaml + ``Chart.yaml``
+4) ``integration_tests/a1mediator/Chart.yaml``
-6) ``a1/openapi.yml``
+6) ``a1/openapi.yaml`` (this is an API version, not a software version; no need to bump on patch changes)
7) in the it/dep repo that contains a1 helm chart, ``values.yaml``, ``Chart.yml``
+
+Version bumping rmr
+--------------------
+rmr is a critical dependency of A1. Bumping the rmr version dependency requires changes in:
+
+1) ``Dockerfile``
+
+2) ``Dockerfile-Unit-Test``
+
+3) ``integration_tests/Dockerfile``
+
+rmr-python is the python binding to rmr . Installing rmr per the above does not install it.
+Bumping the rmr python version dependency requires changes in:
+
+1) ``setup.py``
+
+2) ``integration_tests/Dockerfile``
+
+Run the integration tests after attempting this.
+
+
+Unit Testing
+------------
+Note, before this will work, for the first time on the machine running the tests, run ``./install_deps.sh``. This is only needed once on the machine.
+Also, this requires the python packages ``tox`` and ``pytest``.
+
+::
+
+ tox
+ open htmlcov/index.html
+
+Alternatively, you can run the unit tests in Docker (this is somewhat less nice because you don't get the pretty HTML)
+
+::
+
+ docker build --no-cache -t a1test:latest -f Dockerfile-Unit-Test
+
+Integration testing
+-------------------
+This tests A1’s external API with two test receivers. This depends on helm+k8s, meaning you cannot run this if this is not installed.
+
+Unlike the unit tests, however, this does not require rmr to be installed on the base system, as everything
+runs in Docker, and the Dockerfiles provide/install rmr.
+
+First, build the latest A1 you are testing (from the root):
+::
+
+ docker build --no-cache -t a1:latest .
+
+Note that this step also runs the unit tests, since running the unit tests are part of the Dockerfile for A1.
+
+If you've never run the integration tests before, build the test receiver, which is referenced in the helm chart:
+::
+
+ cd integration_tests
+ docker build --no-cache -t testreceiver:latest .
+
+Finally, run all the tests from the root (this requires the python packages ``tox``, ``pytest``, and ``tavern``).
+::
+
+ tox -c tox-integration.ini
+
+This script:
+1. Deploys 3 helm charts into a local kubernetes installation
+2. Port forwards a pod ClusterIP to localhost
+3. Uses “tavern” to run some tests against the server
+4. Barrages the server with apache bench
+5. Tears everything down
+
+Unless you're a core A1 developer, you should probably stop here. The below instructions
+are for running A1 locally, without docker, and is much more involved (however useful when developing a1).
+
Running locally
-===============
+---------------
-1. This requires that RMR is installed on the base system. (the
- Dockerfile does this when running in Docker)
+1. Before this will work, for the first time on that machine, run ``./install_deps.sh``
-2. It also requires rmr-python >= 0.10.1 installed. (The dockerfile also
- does this)
+2. It also requires rmr-python installed. (The dockerfile does this)
3. Create a ``local.rt`` file and copy it into ``/opt/route/local.rt``.
- Note, the example one in ``local_tests`` will need to be modified for
+ Note, the example one in ``integration_tests`` will need to be modified for
your scenario and machine.
4. Copy a ric manifest into ``/opt/ricmanifest.json`` and an rmr mapping
::
- cp tests/fixtures/ricmanifest.json /opt/ricmanifest.json cp
- tests/fixtures/rmr_string_int_mapping.txt
- /opt/rmr_string_int_mapping.txt
+ cp tests/fixtures/ricmanifest.json /opt/ricmanifest.json
+ cp tests/fixtures/rmr_string_int_mapping.txt /opt/rmr_string_int_mapping.txt
5. Then:
- sudo pip install –ignore-installed .; set -x LD_LIBRARY_PATH
- /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; set -x
- RMR_RCV_RETRY_INTERVAL 500; set -x RMR_RETRY_TIMES 10;
- /usr/bin/run.py
+ ::
+
+ sudo pip install -e .
+ set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; set -x RMR_RCV_RETRY_INTERVAL 500; set -x RMR_RETRY_TIMES 10;
+ /usr/bin/run.py
-Testing locally
-===============
There are also two test receivers in ``integration_tests`` you can run locally.
The first is meant to be used with the ``control_admission`` policy
set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; set -x TEST_RCV_PORT 4563; set -x TEST_RCV_RETURN_MINT 10001; set -x TEST_RCV_SEC_DELAY 5; set -x TEST_RCV_RETURN_PAYLOAD '{"ACK_FROM": "DELAYED_TEST", "status": "SUCCESS"}' ; python receiver.py
To test the async nature of A1, trigger a call to ``test_policy``, which
-will target the delayed receicer, then immediately call
+will target the delayed receiver, then immediately call
``control_admission``. The ``control_admission`` policy return should be
returned immediately, whereas the ``test_policy`` should return after
about ``TEST_RCV_SEC_DELAY 5``. The ``test_policy`` should not block A1
::
curl -v -X PUT -H "Content-Type: application/json" -d '{}' localhost:10000/ric/policies/test_policy
- curl -v -X PUT -H "Content-Type: application/json" -d '{"dc_admission_start_time": "10:00:00", "dc_admission_end_time": "11:00:00"}' localhost:10000/ric/policies/control_admission_time
-
-Finally, there is a test “bombarder” that will flood A1 with messages
-with good message types but bad transaction IDs, to test A1’s resilience
-against queue-overflow attacks
-
-::
-
- set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; python bombard.py
+ curl -v -X PUT -H "Content-Type: application/json" -d '{ "enforce":true, "window_length":10, "blocking_rate":20, "trigger_threshold":10 }' localhost:10000/ric/policies/admission_control_policy
+ curl -v localhost:10000/ric/policies/admission_control_policy
