Airflow System Tests

Files that allows to run Apache Airflow system tests. They are executed in Google Cloud Build by Airflow Breeze.

Setting up environment

1. Preparing Google Cloud Project

Instruction how create Google Cloud Project for system tests is available in airflow-providers-google-setup folder. See instructions: airflow-providers-google-setup/README.md

2. Modify files

Modify following files:

• system_tests/cloudbuild.yaml - so _SERVICE_ACCOUNTS_GCS_BUCKET will point to bucket with service accounts. It is created in the previous step (output of terraform apply command prints bucket name service_account_bucket_name).
• system_tests/cloudbuild.yaml - so LOGS_GCS_BUCKET will point to bucket where Cloud Build logs will be uploaded. It is created in the previous step (output of terraform apply command prints bucket name cloud_build_logs_bucket_name).
• scripts/list_of_tests.sh - comment / uncomment out tests which are / are not intended to run.

3. Build docker image to run Breeze

In airflow_system_tests_env_image folder is located Dockerfile which describes environment to run Breeze (see Breeze prerequisites).

To build image and push it to GCR:

cd airflow_system_tests_env_image
gcloud builds submit .

Docker image will be available at gcr.io/$PROJECT_ID/airflow-system-tests-env:latest.

Running tests

Run multiple system tests whitelisted in scripts/list_of_tests.sh

They will be executed by default on apache/airflow repository on master branch

gcloud builds submit --config=cloudbuild_system_tests.yaml

Command to list all triggered builds will be in the last line of the log, e.g.:

List runs with command:

gcloud builds list --filter "tags='trigger-fdb3a03b-1f99-45fa-8dcb-5cf4d6ca3828'" --format="table[box,margin=3,title='system tests'](id,status,tags,logUrl)"

Run single system test

It will be executed by default on apache/airflow repository on master branch.

bash scripts/run_single_system_test.sh tests/providers/google/cloud/operators/test_speech_to_text_system.py

Run any command in Breeze environment

Example of the command to run Google Memorystore system tests on the Airflow fork and non-default branch.

CMD="./breeze tests --verbose --backend=postgres tests/providers/google/cloud/operators/test_cloud_memorystore_system.py -- -s --system=google"
AIRFLOW_REPO="https://github.com/PolideaInternal/airflow"
BRANCH="fix-to-issue-8286-cloud-memorystore-memcached-operators"

cd system_tests
gcloud builds submit \
    --timeout=3600 \
    --substitutions _CMD="${CMD}",_AIRFLOW_REPO="${AIRFLOW_REPO}",_BRANCH="${BRANCH}"

Setting --timeout for system tests is recommended.

Google Cloud Build configuration to run Breeze

Configuration is located in system_tests folder. It supports following substitutions:

Substitution	Default value	Description
_CMD	./breeze tests --verbose --backend=postgres tests/providers/google/cloud/operators/test_natural_language_system.py -- -s --system=google	Bash command run in airflow-system-tests-env. See Docker image to run Breeze
_AIRFLOW_REPO	https://github.com/apache/airflow	URL of the Airflow git repository.
_BRANCH	master	Name of the branch to checkout.
_TAG_TRIGGER_TYPE	trigger-manual	Tag added do GCB build
_TAG_TEST_NAME	test-name-not-specified	Tag added do GCB build
_LOGS_GCS_BUCKET	airflow-system-tests-logs	GCS bucket where tests logs are uploaded
_SERVICE_ACCOUNTS_GCS_BUCKET	airflow-systest-project-system-tests-rlugtuhw	GCS bucket where service accounts keys are stored (it is output from airflow-providers-google-setup/terraform/modules/service_accounts_setup/outputs.tf, see: airflow-providers-google-setup/README.md)
