test: improve FetchAdapter binding regression tests#1138
Merged
Conversation
…ness Replace 3 weak tests from PR #1130 (hand-written replica, regex-extracted new Function() eval, standalone wrong-precedence demo) with 2 behavioral tests that compile and run the actual generated FetchAdapter in a node:vm sandbox. The remaining regex test is kept as a static source-text guard. The new tests exercise both branches of the generated constructor expression `(fetchFn ?? createFetch()).bind(globalThis)` through the real generated class, catching regressions that string-matching alone misses (e.g. the precedence bug `fetchFn ?? createFetch().bind(globalThis)`).
