Swap E2E Skill

Use this skill when

Updating swap tests in e2e/desktop or e2e/mobile.
Refactoring swap page objects or moving reusable flow logic out of specs.
Fixing PR review comments about dead code, selector ownership, brittle amounts, or multi-step approval assertions.

Current source of truth

Desktop specs: e2e/desktop/tests/specs/*swap*.spec.ts
Desktop swap shared utils:
- e2e/desktop/tests/utils/swapUtils.ts
Desktop page objects:
- e2e/desktop/tests/page/swap.page.ts
- e2e/desktop/tests/page/drawer/swap.confirmation.drawer.ts
Mobile builders/specs:
- e2e/mobile/specs/swap/otherTestCases/swap.other.ts
- e2e/mobile/specs/swap/**/*.spec.ts
Mobile page objects:
- e2e/mobile/page/liveApps/swapLiveApp.ts
- e2e/mobile/page/trade/swap.page.ts

Platform model

Desktop:
- Electron can expose multiple windows (main app + one or more webviews).
- Resolve swap webview via WebViewAppPage.getWebView() using webviewIdentifier title matching, not fixed electronApp.windows()[N] indexes.
- SwapPage methods usually receive electronApp.
- SwapConfirmationDrawer methods act on the main window.
Mobile:
- Webview operations use Detox web helpers.
- Native operations use regular Detox matchers.

Implementation rules

Keep selectors centralized in page objects, not inline in specs.
Keep test IDs as class properties in page objects (avoid repeated string literals in methods).
Do not define reusable workflow methods in spec files. Put them in page objects (for atomic UI actions) or shared utils (for multi-step flows).
Remove dead methods/fields quickly; do not keep unused helpers.
