…uring compilation The underlying Vitest coverage engine depends on specific developer comments like `/* istanbul ignore next */` or `/* v8 ignore next */` being present in the executing code to accurately isolate unmeasured blocks. This commit adds strict behavioral tests to assert that the Angular CLI's in-memory compilation pipeline (via esbuild) properly preserves these structural comments and forwards them reliably to Vitest's coverage processing engine.
