-Maputnik is a MapLibre style editor written using React and TypeScript.
-
-To get started, install all npm packages:
-
-```
-npm install
-```
-
-Verify code correctness by running ESLint:
-
-```
-npm run lint
-```
-
-Or try fixing lint issues with:
-
-```
-npm run lint -- --fix
-```
-
-The project type checked and built with:
-
-```
-npm run build
-```
-
-Install the Playwright browser (first time only):
-
-```
-npx playwright install --with-deps chromium
-```
-
-Then run the end-to-end tests (Playwright starts the dev server automatically):
-
-```
-npm run test
-```
-
-Run the unit tests with Vitest:
-
-```
-npm run test-unit

-
-## Pull Requests
-
-- Pull requests should update `CHANGELOG.md` with a short description of the change.
-
-## Testing
-
-### Prefer end-to-end tests
-
-Most of this codebase is React components, and they are only reachable from an
-end-to-end test. E2E coverage is the primary signal.
-
-Reach for a unit test only for pure logic that e2e cannot cheaply reach (parsers,
-sorting, watchers, stores). Before writing one, check whether e2e already covers
-the file — a unit test that duplicates existing e2e coverage adds test code and
-almost no coverage:
-
-```
-npx nyc report --reporter=text --include="src/libs/style.ts"
-```
-
-Do **not** merge the Vitest (v8) and e2e (istanbul) coverage reports locally. They
-produce conflicting statement maps for the same files and the combined percentage
-is meaningless. Codecov merges the two uploads server-side; that is the number to
-trust. Locally, read them separately:
-
-- e2e: `npx playwright test` then `npx nyc report --reporter=text-summary` (reads `.nyc_output/`)
-- unit: `npx vitest run --coverage` (writes `coverage/`)
-
-### E2E layering
-
-Three layers, and the boundaries matter:
-
-- `e2e/playwright-helper.ts` — generic, app-agnostic browser actions. **The only
-  file allowed to import `@playwright/test`** (besides `e2e/utils/fixtures.ts`).
-- `e2e/maputnik-driver.ts` — domain actions (layers, filters, functions, the
-  style). Knows nothing about `page` or Playwright.
-- `e2e/modal-driver.ts` — actions scoped to a modal, exposed as `when.modal.*`.
-
-Specs get a driver at describe scope and assert fluently:
-
-```ts
-describe("layer editor", () => {
-  const { given, get, when, then } = new MaputnikDriver();
-  ...
-  await then(get.styleFromLocalStorage()).shouldDeepNestedInclude({ layers: [{ id, type: "fill" }] });
-});
-```
-
-New UI interactions belong in a driver, not inline in a spec.
-
-### Writing assertions
-
-- `shouldDeepNestedInclude` is a recursive partial match (`toMatchObject`): nested
-  objects are matched as subsets, arrays and primitives must match exactly
-  (including array length).
-- Assert against the whole style, not an extracted slice. Avoid
-  `get.styleFromLocalStorage().then(style => style.layers.find(...))` — it moves
-  test logic into the test. Compare the real object instead.
-- `Query.then()` is lazy and returns a new `Query`, **not** a Promise. `await
-  get.styleFromLocalStorage()` hangs forever. Use `.get()` to await it directly,
-  or pass the Query to `then(...)`.
-
-### One behaviour per test
-
-If a test needs comments narrating "and now this…", it is several tests. Split it,
-and hoist the shared setup into a nested `describe` + `beforeEach`.
-
-### Test ids
-
-Test ids use the `data-wd-key` attribute and are read via `get.elementByTestId`.
-
-The `Input*` components already accept `data-wd-key` and render it on the real
-`<input>`; the `Field*` wrappers forward it through their `{...props}` spread. So
-passing `data-wd-key` to a `Field*` component is usually enough. Do **not** also
-add it to `Block`/`Fieldset` — the id then matches two elements and locators fail
-in strict mode.
-
-Note `InputNumber` renders `<key>-text` and `<key>-range` when `allowRange` is set,
-and `<key>` otherwise.
-
-### Input commit semantics (common source of "the value didn't save")
-
-- `InputString` only fires its `onChange` on **blur** or **Enter**. Typing alone
-  fires `onInput`. A driver that calls `fill()` must then call `blur()`, or the
-  value never reaches the style.
-- `InputNumber` commits on every change; no blur needed.
-- The autocomplete inputs (layer source, add-layer source) are controlled
-  downshift comboboxes. Keystroke typing is dropped/reordered — `{selectall}` then
-  typing `raster` yields `"exampleaster"`. Use `fill()`, which dispatches a single
-  input event, then pick from the filtered menu.
-- CodeMirror auto-closes brackets and quotes, and types over its own closers, so
-  inserting a well-formed JSON fragment stays well-formed. To break JSON on
-  purpose, insert a bare word.
-
-### Fixtures
-
-Style fixtures live in `e2e/fixtures/`. A new one must be registered in two places
-in `maputnik-driver.ts`: the list in `given.setupMockBackedResponses` and the
-`styleFileByKey` map in `when.setStyle`.
-
-### Verify a new test can fail
-
-A test that passes for the wrong reason is worse than no test. After writing one,
-mutate the expected value and confirm it fails. This has caught real mistakes
-(e.g. a driver that never committed its input, so the assertion was matching a
-value written by the *previous* step).

 ## Tests
+For E2E testing we use [Cypress](https://www.cypress.io/)
 
-### End-to-end tests
+ [Cypress](https://www.cypress.io/) doesn't starts a server so you'll need to start one manually by running `npm run start`.
 
-For E2E testing we use [Playwright](https://playwright.dev/). The tests live in the [`e2e`](/e2e) directory and drive the app through the `MaputnikDriver` page object.
+Now open a terminal and run the following using *chrome*:
-
-The first time you run the tests, install the browser:
-
-```
-npx playwright install chromium
-```
-
-Playwright automatically starts the dev server (`npm run start`) for you, so you can just run:
 
 ```
 npm run test
 ```
-
+or *firefox*:
-Some useful options:
-
 ```
-# see the tests run in a headed browser
+npm run test -- --browser firefox
-npm run test -- --headed
-
-# run a single spec / filter by title
-npm run test -- e2e/map.spec.ts
-npm run test -- -g "zoom level"
-
-# open the interactive UI mode
-npx playwright test --ui
 ```
 
-Running the E2E tests also produces a code-coverage report in `coverage/` (collected via istanbul instrumentation of the dev server).
+See the following docs for more info: (Launching Browsers)[https://docs.cypress.io/guides/guides/launching-browsers]
 
-### Unit & component tests
+You can also see the tests as they run or select which suites to run by executing:
-
-Unit tests and component tests run with [Vitest](https://vitest.dev/); component tests (`*.browser.test.tsx`) use Vitest's browser mode with the Playwright provider.
