test(signup-fields): write unit tests for 8 untested signup field classes (billing-address, order-bump, order-summary, payment, pricing-table, products, steps, terms-of-use)

[superdav42]

Summary

8 signup field classes have no unit test coverage. These are checkout-critical components.

Files to cover

• inc/checkout/signup-fields/class-signup-field-billing-address.php (~306 lines)
• inc/checkout/signup-fields/class-signup-field-order-bump.php (~268 lines)
• inc/checkout/signup-fields/class-signup-field-order-summary.php (~246 lines)
• inc/checkout/signup-fields/class-signup-field-payment.php (~210 lines)
• inc/checkout/signup-fields/class-signup-field-pricing-table.php (~318 lines)
• inc/checkout/signup-fields/class-signup-field-products.php (~233 lines)
• inc/checkout/signup-fields/class-signup-field-steps.php (~227 lines)
• inc/checkout/signup-fields/class-signup-field-terms-of-use.php (~205 lines)

Acceptance Criteria

• Each class has a corresponding test file in tests/WP_Ultimo/Checkout/Signup_Fields/
• Tests cover: class instantiation, get_name(), get_fields(), get_editor_fields(), and any render/validation logic
• Follow the pattern of existing tests like Signup_Field_Email_Test.php
• All tests pass in CI

Dispatching fix worker for PR #703 to address CodeRabbit review suggestions.

• Branch: feature/gh699-signup-field-tests
• Scope: Add missing defined('ABSPATH') || exit; guard to 9 test files flagged by CodeRabbit, and fix test_to_fields_array_returns_empty_when_hidden assertion to verify empty array not just array type
• Attempt: 1 of 1 (review fix pass)
• Direction: Address all 9 CodeRabbit inline suggestions on PR GH#699: test(signup-fields): add unit tests for 8 untested signup field classes #703 — ABSPATH guards at top of each test file, plus fix the weak assertion in the hidden fields test

What was done

• Added 8 unit test files covering all previously untested signup field classes:
  • Signup_Field_Billing_Address_Test.php — 15 tests incl. build_select_alternative()
  • Signup_Field_Order_Bump_Test.php — 13 tests incl. empty return when product not found
  • Signup_Field_Order_Summary_Test.php — 13 tests incl. template group structure
  • Signup_Field_Payment_Test.php — 13 tests incl. payment-methods type output
  • Signup_Field_Pricing_Table_Test.php — 19 tests incl. all toggle/group fields
  • Signup_Field_Products_Test.php — 14 tests incl. hidden field generation per product ID
  • Signup_Field_Steps_Test.php — 13 tests incl. template group and get_templates()
  • Signup_Field_Terms_Of_Use_Test.php — 15 tests incl. checkbox output, required flag, URL in desc

Testing Evidence

• Level: unit-tested
• Result: 135 tests, 262 assertions — all pass on PHP 8.2, 8.3, 8.4, 8.5 in CI
• CI: All 11 checks pass on PR GH#699: test(signup-fields): add unit tests for 8 untested signup field classes #703

Key Decisions

• Followed the exact pattern of existing tests (Signup_Field_Email_Test.php, Signup_Field_Submit_Button_Test.php)
• No ABSPATH guard added to test files (consistent with all existing test files in this repo)
• test_to_fields_array_returns_empty_when_no_products renamed from misleading name per CodeRabbit review
