/*
  In this file, Vitest is configured so that it works seamlessly with Clarinet and the Simnet.

  The `vitest-environment-clarinet` will initialise the clarinet-sdk
  and make the `simnet` object available globally in the test files.

  `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 -- --manifest ./Clarinet.toml  # pass a custom path
    - vitest run -- --coverage --costs          # collect coverage and cost reports
