26 - Flask with Gevent serving
32 This project follows semver. When changes are made, the versions are in:
34 1) ``docs/release-notes.rst``
38 3) ``container-tag.yaml``
40 4) ``integration_tests/a1mediator/Chart.yaml``
42 6) ``a1/openapi.yaml`` (this is an API version, not a software version; no need to bump on patch changes)
44 7) in the it/dep repo that contains a1 helm chart, ``values.yaml``, ``Chart.yml``
49 rmr is a critical dependency of A1. Bumping the rmr version dependency requires changes in:
53 2) ``Dockerfile-Unit-Test``
55 3) ``integration_tests/Dockerfile``
57 rmr-python is the python binding to rmr . Installing rmr per the above does not install it.
58 Bumping the rmr python version dependency requires changes in:
62 2) ``integration_tests/Dockerfile``
64 Run the integration tests after attempting this.
69 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.
70 Also, this requires the python packages ``tox`` and ``pytest``.
75 open htmlcov/index.html
77 Alternatively, you can run the unit tests in Docker (this is somewhat less nice because you don't get the pretty HTML)
81 docker build --no-cache -t a1test:latest -f Dockerfile-Unit-Test
85 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.
87 Unlike the unit tests, however, this does not require rmr to be installed on the base system, as everything
88 runs in Docker, and the Dockerfiles provide/install rmr.
90 First, build the latest A1 you are testing (from the root):
93 docker build --no-cache -t a1:latest .
95 Note that this step also runs the unit tests, since running the unit tests are part of the Dockerfile for A1.
97 If you've never run the integration tests before, build the test receiver, which is referenced in the helm chart:
101 docker build --no-cache -t testreceiver:latest .
103 Finally, run all the tests from the root (this requires the python packages ``tox``, ``pytest``, and ``tavern``).
106 tox -c tox-integration.ini
109 1. Deploys 3 helm charts into a local kubernetes installation
110 2. Port forwards a pod ClusterIP to localhost
111 3. Uses “tavern” to run some tests against the server
112 4. Barrages the server with apache bench
113 5. Tears everything down
115 Unless you're a core A1 developer, you should probably stop here. The below instructions
116 are for running A1 locally, without docker, and is much more involved (however useful when developing a1).
121 1. Before this will work, for the first time on that machine, run ``./install_deps.sh``
123 2. It also requires rmr-python installed. (The dockerfile does this)
125 3. Create a ``local.rt`` file and copy it into ``/opt/route/local.rt``.
126 Note, the example one in ``integration_tests`` will need to be modified for
127 your scenario and machine.
129 4. Copy a ric manifest into ``/opt/ricmanifest.json`` and an rmr mapping
130 table into ``/opt/rmr_string_int_mapping.txt``. You can use the test
131 ones packaged if you want:
135 cp tests/fixtures/ricmanifest.json /opt/ricmanifest.json
136 cp tests/fixtures/rmr_string_int_mapping.txt /opt/rmr_string_int_mapping.txt
142 sudo pip install -e .
143 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;
147 There are also two test receivers in ``integration_tests`` you can run locally.
148 The first is meant to be used with the ``control_admission`` policy
149 (that comes in test fixture ric manifest):
153 set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; python receiver.py
155 The second can be used against the ``test_policy`` policy to test the
156 async nature of A1, and to test race conditions. You can start it with
157 several env variables as follows:
161 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
163 To test the async nature of A1, trigger a call to ``test_policy``, which
164 will target the delayed receiver, then immediately call
165 ``control_admission``. The ``control_admission`` policy return should be
166 returned immediately, whereas the ``test_policy`` should return after
167 about ``TEST_RCV_SEC_DELAY 5``. The ``test_policy`` should not block A1
168 while it is sleeping, and both responses should be correct.
