Development

Start developing

You'll need to insert the environment variables as described within the package @db-ux/db-theme initially.

Afterwards run the following commands:

npm install
npm run build
npm run start

Please mind the conventions for git commits.

Versions

All versions in the package.json files are set to 0.0.0. These are updated during the CI/CD release process.

Tests

TODO: Elaborate on testing setup

Component Tests

Visual regression tests

Playwright is used to create and compare screenshots of each individual component.

Pipeline generated images

On every fail of the visual regression tests in the Default pipeline, we're regenerating the snapshots as a snapshot-*-artifact. Please download these ones from the "Summary" page and commit the updated screenshots with npm run commit:updated-snapshots command from project root.

Manual update

To update screenshots, simply run the following command (ensure Docker is installed and available in your shell):

npm run regenerate:screenshots

If you want to generate the screenshots manually, do the following:

npm run build

# unix
docker run --rm --network host --volume $(pwd):/work/ --workdir /work/ --interactive --tty mcr.microsoft.com/playwright:v1.51.1-focal /bin/bash

# windows - allow file sharing (windows pop up)
docker run --rm --network host --volume ${PWD}:/work/ --workdir /work/ --interactive --tty mcr.microsoft.com/playwright:v1.51.1-focal /bin/bash

npm install

cd output/${frameworkFolder}  (replace ${frameworkFolder} with the appropriate folder name)

npx playwright test --update-snapshots

You can also use docker-compose to test or regenerate screenshots.

  • testing: docker-compose --file ./e2e/docker-compose.yml up
  • update screenshots: docker-compose --file ./e2e/docker-compose.regenerate.yml up
