ci: reject an empty project-name input before running Playwright

[TallblokeUK]

Follow-up from review of #527. The input is declared required and both callers pass literal names, but the step now also refuses a blank value with a clear message rather than running the whole suite with no project selected.

Summary by CodeRabbit

• Bug Fixes
  • Playwright test runs now fail early with a clear error when the project name is missing or contains only whitespace.

Walkthrough

The Playwright workflow now validates PLAYWRIGHT_PROJECTS before test execution. Empty or whitespace-only input causes an error.

Changes

Playwright workflow validation

Layer / File(s)	Summary
Validate project input .github/workflows/playwright-test.yml	At line 255, the workflow exits with an error when PLAYWRIGHT_PROJECTS is empty or contains only spaces.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 5b143

Whitespace-only project input can still run Playwright without a selected project, while invalid inputs also consume the full CI setup before failing. Update the validation to run early and reject all whitespace before merge.

Full details: Correctness And Security

Explanation

The new check at .github/workflows/playwright-test.yml:255 removes only literal spaces. A tab-only project-name passes the check. read -ra projects then creates zero projects, so the workflow runs npm run test:playwright with no --project argument instead of failing.

Resolution

At .github/workflows/playwright-test.yml:255, validate that the input contains a non-whitespace character, for example with [[ "$PLAYWRIGHT_PROJECTS" =~ [^[:space:]] ]] || { echo "The project-name input is empty; nothing to run." >&2; exit 1; }.

Full details: Ponytail: No Over-Engineering

Explanation

No needless complexity is introduced. The pull request adds one inline Bash guard at .github/workflows/playwright-test.yml:255. It uses the existing environment variable and shell, with no abstraction, dependency, or scaffolding.

Explanation

The title is a short conventional-commit summary. The description is present. The PR description, lines 1-2, includes review history and author reasoning before the factual change summary. The commit body has no AI-attribution trailer, and the changed diff shows no private, internal, or cross-repository details.

Full details: Scope Discipline

Explanation

The PR has one focused concern. It adds a blank project-name check at .github/workflows/playwright-test.yml:255. The commit changes no other files or behavior areas. No unrelated concern requires a split PR.
