Debugging the `unit-test` builder can be challenging, particularly when using runners like Vitest that rely on virtual or in-memory files for test setup and execution. It is difficult to inspect the final build artifacts that are passed to the test runner. This commit introduces a new hidden boolean option, `dumpVirtualFiles`, to the `unit-test` builder's schema. When this option is enabled, the builder will write the full build output to a directory within the project's cache (`.angular/cache/<project-name>/unit-test/output-files/`). This provides a crucial debugging mechanism, allowing developers to inspect the exact contents of the files being used in the test execution, which helps in troubleshooting complex configuration and build-related problems.
