+
+## 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).
