A.

Selectorstabiliteit

Selectors moeten blijven werken na dynamische klassen, identieke broers/zussen en locale-wisselingen.

4 fixtures
A1 · Static form (smoke)
Three text fields + submit. The baseline every recorder must pass.
[data-testid="*-input"]
A2 · Dynamic class hashes
Buttons get fresh `btn__primary--ab3f9c` classes on every load.
.btn__primary--ab3f9c
A3 · Identical sibling tiebreak
Six rows with identical "Pick" buttons. Only position distinguishes them.
fingerprintIndex: 3
A4 · Locale-stable selectors via data-i18n-key
"Continue" / "继续" / "Weiter" — same DOM, three languages.
data-i18n-key="action.continue"
B.

Async + timing

Afspelen moet wachten op SPA-routes, gedebouncede zoekopdrachten en lui gemonteerde modals.

2 fixtures
B1 · SPA route transition
Tab switches mount different content 350ms later — no real navigation.
pushState → waitFor()
B3 · Lazy-mounted modal
The modal appears 700ms after you click the trigger button.
elementVisible(700ms)
C.

Multi-surface

Iframes, Shadow DOM en multi-tab-flows zijn eerste klas.

4 fixtures
C1 · Same-origin iframe
A button inside an iframe. Recorder injects into the iframe; actions carry a `frameId`.
frameId: <non-zero>
C2 · Sensitive-field redaction
Password, phone, and credit-card inputs are auto-masked before they hit storage.
masked: true · ***
C3 · Shadow DOM piercing
`<my-card>` Web Component with an open shadow root.
kind: "shadow"
C4 · Multi-tab (target="_blank")
Click a link that opens a second tab, then click on that new tab.
switchTab → tabs.create

Invoer-specialiteit

Drag/drop, bestandsupload, modifier-combo's, contenteditable, klembord, ARIA-combobox.

6 fixtures
D1 · HTML5 drag & drop
Drag a card from "Backlog" onto "In progress".
drag → dataTransfer
D2 · File upload
Pick a file. Recorder captures filename + size + mime — never the bytes.
fileMeta · no bytes
D3 · Modifier-key chords
Cmd/Ctrl + K opens a palette; Ctrl + Enter submits.
metaKey + "k"
D4 · contenteditable richtext
A div with `contenteditable="true"` — like a Notion/Slack composer.
inputType: "contenteditable"
D5 · Clipboard (copy + paste)
Copy a value from one place, paste it into another.
Cmd-C → Cmd-V
D6 · ARIA combobox
Type to filter, click an option.
