Running tests

Instructions on how to run all existence tests.

E2E tests

Initial steps:

  1. Run CVAT instance:
    docker compose \
              -f docker-compose.yml \
              -f docker-compose.dev.yml \
              -f components/serverless/docker-compose.serverless.yml \
              -f tests/docker-compose.minio.yml \
              -f tests/docker-compose.file_share.yml up -d
    
  2. Add test user in CVAT:
    docker exec -i cvat_server \
              /bin/bash -c \
              "echo \"from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@localhost.company', '12qwaszx')\" | python3 ~/manage.py shell"
    
  3. Install npm dependencies:
    cd tests
    yarn --frozen-lockfile
    

If you want to get a code coverage report, instrument the code:

yarn --frozen-lockfile
yarn run coverage

Running tests

yarn run cypress:run:chrome
yarn run cypress:run:chrome:canvas3d

REST API, SDK and CLI tests

Initial steps

  1. Follow this guide to prepare cvat-sdk and cvat-cli source code
  2. Install all necessary requirements before running REST API tests:
    pip install -r ./tests/python/requirements.txt
    pip install -e ./cvat-sdk
    pip install -e ./cvat-cli
    
  3. Stop any other CVAT containers which you run previously. They keep ports which are used by containers for the testing system.

Running tests

Run all REST API tests:

pytest ./tests/python

This command will automatically start all necessary docker containers.

If you want to start/stop these containers without running tests use special options for it:

pytest ./tests/python --start-services
pytest ./tests/python --stop-services

If you need to rebuild your CVAT images add --rebuild option:

pytest ./tests/python --rebuild

If you want to get a code coverage report, use special option for it:

COVERAGE_PROCESS_START=.coveragerc pytest ./tests/python --rebuild --cov --cov-report xml

Debugging

Currently, this is only supported in deployments based on Docker Compose, which should be enough to fix errors arising in REST API tests.

To debug a server deployed with Docker, you need to do the following:

  • Adjust env variables in the docker-compose.dev.yml file for your test case

  • Rebuild the images and start the test containers:

CVAT_DEBUG_ENABLED=yes pytest --rebuild --start-services tests/python

Now, you can use VS Code tasks to attach to the running server containers. To attach to a container, run one of the following tasks:

  • REST API tests: Attach to server for the server container
  • REST API tests: Attach to RQ low for the low priority queue worker
  • REST API tests: Attach to RQ default for the default priority queue worker

If you have a custom development environment setup, you need to adjust host-remote path mappings in the .vscode/launch.json:

...
"pathMappings": [
   {
      "localRoot": "${workspaceFolder}/my_venv",
      "remoteRoot": "/opt/venv",
   },
   {
      "localRoot": "/some/other/path",
      "remoteRoot": "/some/container/path",
   }
]

Extra options:

  • If you want the server to wait for a debugger on startup, use the CVAT_DEBUG_WAIT_CLIENT environment variable:
    CVAT_DEBUG_WAIT_CLIENT=yes pytest ...
    
  • If you want to change the default debugging ports, check the *_DEBUG_PORT variables in the docker-compose.dev.yml

Unit tests

Initial steps

  1. Install necessary Python dependencies:
    pip install -r cvat/requirements/testing.txt
    
  2. Install npm dependencies:
    yarn --frozen-lockfile
    
  3. Build CVAT server image
    docker compose -f docker-compose.yml -f docker-compose.dev.yml build cvat_server
    
  4. Run cvat_opa container
    docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d cvat_opa
    

Running tests

  1. Python tests
    python manage.py test --settings cvat.settings.testing cvat/apps -v 2
    

If you want to get a code coverage report, run the next command:

coverage run manage.py test --settings cvat.settings.testing cvat/apps -v 2
  1. JS tests
    cd cvat-core
    yarn run test
    

Debug python unit tests

  1. Run server: tests debug task in VSCode
  2. If you want to debug particular tests then change the configuration of the corresponding task in ./vscode/launch.json, for example:
    {
        "name": "server: tests",
        "type": "python",
        "request": "launch",
        "justMyCode": false,
        "stopOnEntry": false,
        "python": "${command:python.interpreterPath}",
        "program": "${workspaceRoot}/manage.py",
        "args": [
            "test",
            "--settings",
            "cvat.settings.testing",
            "cvat/apps/engine",
            "-v", "2",
            "-k", "test_api_v2_projects_",
        ],
        "django": true,
        "cwd": "${workspaceFolder}",
        "env": {},
        "console": "internalConsole"
    }
    

IAM and Open Policy Agent tests

Generate tests

python cvat/apps/iam/rules/tests/generate_tests.py \
   --output-dir cvat/apps/iam/rules/

Run testing

  • In a Docker container
docker run --rm -v ${PWD}/cvat/apps/iam/rules:/rules \
   openpolicyagent/opa:0.45.0-rootless \
   test /rules -v
  • or execute OPA directly
curl -L -o opa https://openpolicyagent.org/downloads/v0.45.0/opa_linux_amd64_static
chmod +x ./opa
./opa test cvat/apps/iam/rules
