Oclif generates a test file per command automatically and provides a library to execute the command in a simple way.

When a new command is created by executing the command: npx oclif command command_name a matching test file is created under test folder:
src/
commands/
command_name.ts
test/
commands/
command_name.test.ts
Al the tests are discoverable by the script npm run test executing : "test": "nyc --extension .ts mocha --forbid-only "test/**/*.test.ts""
