Sets up integration test suite for oxc-resolver functionality to support manual testing requirements from oxc-project/oxc-resolver#790.

Tests Added

Five integration tests covering common resolver scenarios:

  • oxc_resolver_integration - Conditional exports (import/require/default), subpath exports, nested platform conditions
  • package_exports_wildcard - Wildcard patterns (./features/*, ./utils/*) in package.json exports
  • self_referencing_package - Packages importing from themselves via exports field
  • extensionless_typescript - Extension rewriting (.js.ts, .mjs.mts) for esbuild compatibility
  • browser_field_resolution - Platform-specific entry points (browser vs node)

Structure

Each test follows standard Rolldown fixture pattern with mock node_modules packages and executable assertions:

// crates/rolldown/tests/rolldown/resolve/package_exports_wildcard/main.js
import { feature1 } from 'wildcard-lib/features/feature1'
import { utilA } from 'wildcard-lib/utils/utilA'

assert.strictEqual(feature1, 'feature-one')
assert.strictEqual(utilA, 'util-a')

All tests currently pass with oxc-resolver 11.11.1. Ready to validate future resolver improvements or mark expected behavior for #790 changes.

Documentation: RESOLVER_TESTS.md and crates/rolldown/tests/rolldown/resolve/README.md

Original prompt

Could you help me setup some integration tests that fails right now but should pass in Rolldown test suite? I have an implementation that require manual testing before publish oxc-project/oxc-resolver#790

Add integration tests for oxc-resolver functionality including:
- Conditional exports (import/require)
- Subpath exports with wildcards
- Self-referencing packages
- TypeScript extensionless imports (.js -> .ts, .mjs -> .mts)
- Browser field resolution
- Nested conditional exports

These tests validate expected resolver behavior and serve as regression
tests for future oxc-resolver improvements.
