Issue #4: [Bug] CI pipeline silently swallows test failures — broken builds pass as green

[GoodnessJohn]

Description:

The CI workflow uses || echo "..." to suppress test runner exit codes:

❌ .github/workflows/ci.yml

• name: Component tests
  run: npx vitest run --config vitest.config.ts || echo "Vitest not configured, skipping"
• name: E2E tests
  run: npx playwright test || echo "No e2e to run"
  If tests fail (not just "not found"), the pipeline still reports success. A broken build can merge undetected.

Fix:

Separate "not configured" from "configured but failing" by checking for the config file's existence first
Use proper conditional steps with if: hashFiles('vitest.config.ts') != ''
Remove the || echo fallback entirely once the test infra is confirmed working

• name: Component tests
  if: hashFiles('vitest.config.ts') != ''
  run: npx vitest run --config vitest.config.ts

• name: E2E tests
  if: hashFiles('playwright.config.ts') != ''
  run: npx playwright test
  Also: rename the package.json name from "nextjs-postgresql-template" to "rentar-pay-backend".

Acceptance criteria:

CI step fails if vitest exits with a non-zero code
CI step fails if playwright exits with a non-zero code
package.json name updated to rentar-pay-backend
CI pipeline runs green only when all configured tests pass
