Testing¶

Unit tests¶

Unit tests are performed via vitest, via the test script defined in package.json.

End-to-end testing¶

E2E tests are done using playwright. They can be executed using the following command:

npx playwright test

To print Svelte webserver log set the environment variable DEBUG=pw:webserver.

To execute the tests seeing the browser add the --headed flag or the --debug flag if you need to watch them step by step.

OAuth2 test requires a running instance of dexidp test image and a fractal-server instance configured to use it.

To skip OAuth2 test set the environment variable SKIP_OAUTH_TEST to true.

To skip Pixi test set the environment variable SKIP_PIXI_TEST to true.

To run the OAuth2 test locally add the following configuration to .fractal_server.env:

OAUTH_CLIENT_NAME=dexidp
OAUTH_CLIENT_ID=client_test_web_id
OAUTH_CLIENT_SECRET=client_test_web_secret
OAUTH_REDIRECT_URL=http://localhost:5173/auth/login/oauth2/
OAUTH_OIDC_CONFIG_ENDPOINT=http://127.0.0.1:5556/dex/.well-known/openid-configuration

And then start the test IdP container:

docker run -d --rm -p 5556:5556 ghcr.io/fractal-analytics-platform/oauth:0.1

Coverage¶

Warning: code coverage results are not reliable at the moment

Coverage for the unit tests:

npx vitest --coverage

Warning: coverage takes some time, since we are using the option { all: true }.

Local `fractal-server` instance¶

The lib/fractal-server folder includes basic instructions to get a local instance of fractal-server running.

Remote `fractal-server` instance¶

One could also test a local fractal-web instance with a remote fractal-server one. If SSH access is possible, then a command like

REMOTE_PORT=8010
LOCAL_PORT=8000
REMOTE_USER=...
REMOTE_HOST_IP=...

ssh $REMOTE_USER@$REMOTE_HOST_IP -L $LOCAL_PORT:127.0.0.1:$REMOTE_PORT -N

should work and forward the remote port REMOTE_PORT to the LOCAL_PORT on localhost, so that fractal-web can use it from the local machine. Note that the required details for the ssh -L command may be different in each specific case, depending for instance on the fractal-server configuration (e.g the --bind argument of gunicorn), or on whether an additional proxy is needed to reach the remote host.
