Code Review

This pull request updates the create_parser method in CliTestOptions to accept a name parameter, allowing the command-line usage banner to dynamically display the correct subcommand name (e.g., 'test' or 'functest'). The reviewer suggests adding a Sorbet type signature (sig) to the updated create_parser method to maintain type safety and clarity.

Since CliTestOptions extends T::Sig and the file is typed (# typed: true), it is highly recommended to define a Sorbet signature for the create_parser method to ensure type safety and clarity for its parameter and return type.

    sig { params(name: String).returns(OptionParser) }
    def create_parser(name)

Pull request overview

This PR fixes the CLI help/usage text for test-related subcommands by parameterizing the test option parser’s banner so it reflects the actual subcommand name (e.g., test vs functest).

Changes:

• Update CliTestOptions#create_parser to accept the subcommand name and interpolate it into the usage banner.
• Pass explicit subcommand names when constructing the test and functest subparsers.
