   - Run a specific unit test target (e.g., `pnpm bazel test //packages/angular/build:test`). Note that package `:test` targets may exclude builder integration tests (such as specs under `**/builders/**/tests/**`).
   - Run a specific builder integration test target (e.g., `pnpm bazel test //packages/angular/build:library_integration_tests` or `pnpm bazel test //packages/angular/build:application_integration_tests`).
   - Query all test targets: `pnpm bazel query "tests(//packages/...)"`
-  - Find the exact test target for a specific spec file: `pnpm bazel query "kind(jasmine_test, rdeps(//packages/..., <path/to/file_spec.ts>))"`
+  - Find the exact test target for a specific spec file (using its workspace-relative path, which Bazel resolves as a source file target): `pnpm bazel query "kind(jasmine_test, rdeps(//packages/..., <relative/path/to/file_spec.ts>))"`
   - Focus specific tests when debugging: use `fdescribe()` and `fit()`. NEVER commit focused tests to the repository.
   - Run tests without sharding when isolating or debugging: use `--config=no-sharding` with a specific test target (e.g., `pnpm bazel test //packages/angular/build:library_integration_tests --config=no-sharding`).
     This disables test sharding (`--test_sharding_strategy=disabled`) and flaky test retries (`--flaky_test_attempts=1`).
