overlookmotel 91343913ca fix(semantic): transform checker check unresolved references (#5096) 
Transform checker check root unresolved references.

The transform checker is now checking pretty much everything it can.

Only fields of `ScopeTree` and `SymbolTable` that it's *not* checking are those which contain `AstNodeId`s, because transformer does not create node IDs at present:

* `ScopeTree::node_ids`
* `SymbolTable::declarations`
* `Reference::node_id`

Checking also only proceeds in "from AST" direction.

i.e. for each `SymbolId` which appears in the AST, we check everything about that symbol. But we *don't* go through all the "rows" in `SymbolTable` and check if there are any extra symbols in the table which aren't in the AST.

Presumably transformer will leave a lot of old symbols lying around in `SymbolTable` (ditto scopes and references). We'd need to add `ScopeFlags::Deleted`, `SymbolFlags::Deleted` and `ReferenceFlags::Deleted` for the transformer to be able to "delete" existing symbols.

Transformation Conformance Test Runner

Execution

This test runner uses the transformation plugin test suite from the babel repository.

The failing test cases are listed in ./babel.snap.md

To get started, run

cargo run -p oxc_transform_conformance

or watch for changes

just watch 'run -p oxc_transform_conformance'

Options

--filter

To filter for a specific test case, apply the --filter path option, e.g.

cargo run -p oxc_transform_conformance -- --filter react/arrow-functions

--exec

The babel test suite contains many exec.js files, they need to be executed by a runtime.

Bun is the preferred way to execute these tests, which you may install them via https://bun.sh/docs/installation.

Once bun is installed, apply the --exec flag:

cargo run -p oxc_transform_conformance -- --exec

The failing test cases are listed in ./babel_exec.snap.md.
