> Note: Did not add additional tests or make many changes to the utils, possible refactoring on the following PR. This PR split the legacy tests into four sections to improve the maintenance and concurrency of CNA tests: - `prompts`: target prompt interactions. `Y/n` - `examples`: target `--example` and `--example-path` flags. - `templates`: target the flag values such as `--app`, `--eslint`, etc. - `package-manager`: target package managers: npm, pnpm, yarn, bun --------- Co-authored-by: JJ Kasper <[email protected]>
