Summary of Changes

Hello @cornmander, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new unit test for the readWasmBinaryFromDisk utility. The test is designed to confirm that the function can successfully read a WebAssembly binary from disk and return its content as a Uint8Array, using a dedicated fixture for accurate byte-level comparison.

Highlights

• New Unit Test: Added a unit test for the readWasmBinaryFromDisk utility function to ensure it correctly loads WebAssembly binary files.
• Fixture-Backed Testing: The new test utilizes a dummy.wasm fixture file to simulate a real WebAssembly binary, ensuring robust validation.
• Data Verification: The test verifies that the readWasmBinaryFromDisk function returns the WASM binary as a Uint8Array and that its content precisely matches the bytes of the fixture file.
