Running tests

Instructions on how to run all existence tests.

E2E tests

Initial steps:

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

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"

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

Follow this guide to prepare cvat-sdk and cvat-cli source code

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

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

Install necessary Python dependencies:

pip install -r cvat/requirements/testing.txt

Install npm dependencies:
```
yarn --frozen-lockfile
```

Build CVAT server image

docker compose -f docker-compose.yml -f docker-compose.dev.yml build cvat_server

Run cvat_opa container

docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d cvat_opa

Running tests

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

JS tests
```
cd cvat-core
yarn run test
```

Debug python unit tests

Run server: tests debug task in VSCode

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
