Runs JavaScript-like sigils as Volt test assertions.

This extends ExUnit's assert/1 for ~JS, ~TS, ~JSX, and ~TSX snippets while delegating all other expressions to ExUnit.Assertions.assert/1.

Delegates to ExUnit's assert/2.

Runs a JavaScript or TypeScript snippet as a Volt test assertion.

The snippet body is wrapped in a single Volt test(...). Top-level import declarations are preserved outside the wrapper so snippets can import app code while keeping assertions inline in ExUnit tests.
