The CLI validation regex rejected --wp=beta despite resolveWordPressRelease() supporting it. Users attempting to test beta versions received an unhelpful error that didn't list all valid options.

Changes

  • Validation: Added beta to the regex pattern in isValidWordPressSlug()
  • Error message: Updated to explicitly list all keyword versions: latest, beta, trunk, nightly
  • Tests: Added unit and integration tests for version validation

Before/After

# Before
$ wp-playground server --wp=beta
Error: Unrecognized WordPress version. Please use "latest", a URL, or a numeric version...

# After
$ wp-playground server --wp=beta
Starting a PHP server...
Setting up WordPress beta
Resolved WordPress release URL: https://wordpress.org/wordpress-6.8-beta1.zip

Invalid versions like brazil are still rejected, now with clearer guidance on valid formats.

<issue_title>[CLI] Throws a message for invalid WordPress version</issue_title>
<issue_description>### Prerequisites

  • I have carried out troubleshooting steps and I believe I have found a bug.
  • I have searched for similar bugs in both open and closed issues and cannot find a duplicate.

Describe the bug

When an invalid value is passed to the flag --wp on playground CLI, it loads the latest version without notifying the users. It can be confusing if the user passes an invalid flag.

for example, I have requested the beta version, similar behavior to the web version of the playground, and it downloads version 6.8.3:

npx @wp-playground/cli@latest server --version=beta   
Starting a PHP server...
Setting up WordPress latest
Resolved WordPress release URL: https://downloads.w.org/release/wordpress-6.8.3.zip
Fetching SQLite integration plugin...
Booting WordPress...
PHP.request() is deprecated. Please use the new PHPRequestHandler() instead.
Booted!
Running the Blueprint...
Running the Blueprint – 100%
Finished running the blueprint
WordPress is running on http://127.0.0.1:9400 with 1 worker(s)

First, I was confused it was a bug on the CLI related to the beta version, later I realized beta is not a valid value for the flag --wp:

npx @wp-playground/cli@latest server --version=brazil 
Starting a PHP server...
Setting up WordPress latest
Resolved WordPress release URL: https://downloads.w.org/release/wordpress-6.8.3.zip
Fetching SQLite integration plugin...
Booting WordPress...
PHP.request() is deprecated. Please use new PHPRequestHandler() instead.
Booted!
Running the Blueprint...
Running the Blueprint – 100%
Finished running the blueprint
WordPress is running on http://127.0.0.1:9400 with 1 worker(s)

Expected behavior

The CLI should notify the user that the flag is not valid

  • Ideally, suggest one of the valid versions without crashing

Actual behavior

The CLI is loading the latest version without notifying users that the flag has an invalid value

Steps to reproduce

  1. Go to the terminal
  2. Run npx @wp-playground/cli@latest server --version=brazil
  3. Check the output

Isolating the problem

  • I have deactivated other plugins and confirmed this bug occurs when only this plugin is active.
  • This bug happens with a default WordPress theme active.
  • I can reproduce this bug consistently using the steps above.</issue_description>

@adamziel I think the point is here, the conditional check if the version is valid, if not skip it and doesn't do anything. I think we should throw a message if the value is not valid

if (args.wp !== undefined && !isValidWordPressSlug(args.wp)) {
					try {
						// Check if is valid URL
						new URL(args.wp);
					} catch {
						throw new Error(
							'Unrecognized WordPress version. Please use "latest", "beta", "trunk", "nightly", a URL, or a numeric version such as "6.2", "6.0.1", "6.2-beta1", or "6.2-RC1"'
						);
					}
				}
