Visual Regression

We use SuperCI + reg-suit + storybook-chrome-screenshot or cypress to conduct visual regression tests with every PR.

Storybook

To ignore given story use ignoreDuringVisualRegression helper. To create screenshots locally, run: yarn storybook:screenshots.

Cypress E2E tests screenshots

E2E screenshots are pretty hard to make deterministic. We use two two attribute helpers: data-vis-reg-mask (to mask with black rectangle) and data-vis-reg-hide to hide entirely. Each screenshot is made in multiple sizes.

E2E tests

yarn cypress:dev  # to develop tests

yarn cypress:run  # to run all tests

Env files

By default app will try to load .env.$NODE_ENV file and fallback to .env. You can use ENV env variable to override this mechanism for example: ENV=dev will load .env.dev file.

Feature switches

REACT_APP_INSTANT_ENABLED

Inside the app always check process.env.REACT_APP_INSTANT_ENABLED = "1" do not use any helpers to enable simple dead code elimination done by webpack.

REACT_APP_GRAPHQL_DEVMODE

A parameter forwarded to vulcan0x, useful for development purposes.

REACT_APP_TAX_EXPORTER_ENABLED

Enables Tax Exporter button on Account page. Feature allows user to export trade history into CSV format.
