## Environment Variables
The following environment variables are recognized by the frontend process.
| Name | Possible Values | Description |
|--------------------------|----------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
2023-02-05 08:31:33 +00:00
| HD_BASE_URL | Any URL with protocol, domain and optionally directory and port. Must end with a trailing slash. (e.g. `http://localhost:3001/` ) | The URL under which the frontend is expected. Setting this is mandatory so the server side rendering can generate assets URLs. You only need to set this yourself if you use the production mode. |
| HD_RENDERER_BASE_URL | Same as `HD_BASE_URL` | You can provide this variable if the renderer should use another domain than the editor. This is recommended for security reasons but not mandatory. This variable is optional and will fallback to `HD_BASE_URL` |
2022-11-11 10:27:05 +00:00
| NEXT_PUBLIC_USE_MOCK_API | `true` , `false` | Will activate the mocked backend |
| NEXT_PUBLIC_TEST_MODE | `true` , `false` | Will activate additional HTML attributes that are used to identify elements for test suits. |
Variables that start with `NEXT_PUBLIC_` will be compiled into the build. You can't change them at after compilation.
You shouldn't need to set them yourself. Use the designated npm tasks instead.
## UI Test
Curious about the new look and feel? We provide a demo of the new UI on [hedgedoc.dev ](https://hedgedoc.dev ). This
version uses mocked data and has no data persistence.
The UI test is hosted by [netlify ](https://netlify.com ). Please check
their [privacy policy ](https://netlify.com/privacy ) as well as [ours ](https://hedgedoc.org/privacy-policy ).
## Running Tests
### Unit
Unit testing is done via jest.
1. Run `yarn test`
### End2End
We use [cypress ](https://cypress.io ) for e2e tests.

1. Start the frontend with `yarn start:dev:test` (or use a test build using `yarn build:test` which you can start
2022-11-11 10:27:05 +00:00
using `yarn start` ). The usage of `:test` is mandatory!
2. Run `yarn cy:open` to open the cypress test loader
3. Choose your browser and start a test suite
To run all tests in a headless browser use `yarn cy:run:chrome` or `yarn cy:run:firefox`
### Bundle analysis
You can inspect the generated production-bundle files to look for optimization issues.
1. run `yarn analyze` . This will overwrite any existing builds!
2. Open the generated `.next/server/analyze/server.html` in your favourite browser
