# Introduction The idea here is to improve perf nor fluidity of both storybook build and tests execution duration. ## Levers: - Storybook tests [shards](https://storybook.js.org/docs/writing-tests/test-runner) - Refactored storybook's build caching using `actions/cache/restore` and `actions/cache/save` to avoid useless computation with we wanna just write or retrieve it - Running storybook build with --test [flag](https://storybook.js.org/docs/api/main-config/main-config-build) ( please note that we only disable docs addons in order to keep coverage up and running ) closes https://github.com/twentyhq/core-team-issues/issues/49
