+**Expanding `examples/basic` (for comprehensive features)**
 Best for features that should be part of the main test suite. `examples/basic` is mainly used for e2e testing:
 
 1. Add your test case files to `examples/basic/src/routes/`
 2. Update the routing in `examples/basic/src/routes/root.tsx`
 3. Add corresponding tests in `e2e/basic.test.ts`
 
+**Using `setupInlineFixture` (for specific edge cases)**
+Best for testing specific edge cases or isolated features. See `e2e/ssr-thenable.test.ts` for the pattern.
