+
+  `vitestSetupFilePath` points to a file in the `@hirosystems/clarinet-sdk` package that does two things:
+    - run `before` hooks to initialize the simnet and `after` hooks to collect costs and coverage reports.
+    - load custom vitest matchers to work with Clarity values (such as `expect(...).toBeUint()`)
+
+  The `getClarinetVitestsArgv()` will parse options passed to the command `vitest run --`

+    - vitest run -- --coverage --costs          # collect coverage and cost reports
