Rewrite service and collection configuration test suites with React Testing Library

[jonathangreen]

Description

Rewrites the service and collection configuration test suites with React Testing Library.

Migrated suites (old enzyme test in src/components/__tests__/ removed, RTL test added/expanded in tests/jest/components/):

• ServiceEditForm
• EditableConfigList
• SelfTests
• ProtocolFormField
• Collections

Migration notes (carried over from #316, for the suites in this PR):

• ServiceEditForm was one of the largest suites in the migration (originally 1087 LOC).
• Enzyme live-instance-method spies become observable behavior — e.g. asserting the submitted FormData (via the shared FormData shim) rather than that a save method was called.
• Tiny test subclasses drive branches that the base EditableConfigList method short-circuits (Collections extends EditableConfigList).
• Where a suite covers a connected panel, it renders the connected default export so mapStateToProps/mapDispatchToProps stay covered.

This is one of four PRs splitting the oversized #316 into independently reviewable pieces, grouped by feature area. Each split branches from main and touches a disjoint set of component test files, so the four can be reviewed and merged in any order.

Motivation and Context

#316 rewrote the HARD-tier and remaining merge test suites from enzyme to React Testing Library in a single ~11k-line change, which is impractical to review. Splitting it by feature area keeps each PR at a reviewable size while preserving the same net result. These were among the hardest suites in the mocha/chai/enzyme → jest/RTL migration — enzyme mounted them and poked class internals, so the rewrites re-express those assertions as DOM and behavior checks.

How Has This Been Tested?

npx jest --selectProjects unit over the migrated suites on this branch: 5 suites / 134 tests pass. No application source changes — test files only.

Checklist:

• All new and existing tests passed.

Code Review

• Read the new/modified RTL test files
• Read the source components under test
• Compare against deleted enzyme suites for coverage gaps
• Post review findings

Summary

This is a clean, high-quality enzyme→RTL migration. The rewrites consistently replace instance-method spying with observable behavior — the FormData shim to assert what save/registerLibrary actually receive, tiny test subclasses to drive the base EditableConfigList/ServiceEditForm override hooks (isLibraryRemovalPermitted, canCreate/canDelete/canEdit), and rendering the connected default exports so mapStateToProps/mapDispatchToProps stay covered. Date formatting in SelfTests is verified to mirror the component's own local-time formatDate, so those assertions are not timezone-fragile. No skipped/focused tests, and Codecov shows all modified lines covered. The coverage gaps raised earlier in review were addressed (the hidden-variant it.each, the hidden-select contract) or tracked separately with the author's acknowledgment (the hidden color-picker update path → #322). I found no correctness issues; one very minor nit below.

Details

Nit: tests/jest/components/EditableConfigList.test.tsx:972

The footer link is located with container.querySelector("p"), which grabs the first <p> in the tree. It works today because the only <p> in this render is the footer, but it's the same broad-selector smell that was narrowed for the adjacent info-alert assertion in this file. Targeting the footer by its distinctive text (e.g. within(footer) off screen.getByText(/Problems with your things\?/)) keeps the two sibling assertions consistent and robust.

const footer = withSelfTests.container.querySelector("p");

Greptile Summary

This PR rewrites service and collection configuration tests with React Testing Library.

• Removed the legacy Enzyme suites for service and collection configuration components.
• Added RTL coverage for ServiceEditForm, EditableConfigList, SelfTests, ProtocolFormField, and Collections.
• Expanded behavior-focused tests for hidden protocol fields, list/menu forwarding, form submission, collection deletion, and self-test flows.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
