Phase 1: Benchmarks Read/View Implementation - Complete

Overview

This document verifies the implementation of Phase 1 Benchmarks CRUD: Read/View operations.

Implemented Features

1. API Endpoints

GET /api/benchmarks

Location: src/app/api/benchmarks/route.ts

  • Lists all benchmarks from the database
  • Requires authentication
  • Supports filtering by industry_id and dimension_id query parameters
  • Orders results by created_at descending
  • Returns 401 if unauthorized
  • Returns 500 on database errors
  • Test Coverage: 6 unit tests

GET /api/benchmarks/[id]

Location: src/app/api/benchmarks/[id]/route.ts

  • Retrieves a single benchmark by ID
  • Requires authentication
  • Returns 404 if benchmark not found
  • Returns 401 if unauthorized
  • Returns 500 on database errors
  • Test Coverage: 4 unit tests

2. UI Components

Benchmarks List Table Component

Location: src/app/dashboard/benchmarks/benchmarks-list-table.tsx

  • Client-side component for displaying benchmarks in a responsive table
  • Reusable across different pages
  • Handles delete operations with confirmation
  • Provides edit navigation links
  • Shows success/error messages
  • Responsive design for mobile, tablet, and desktop

Table Columns:

  • Dimension (name and code)
  • Industry (name)
  • Value (formatted benchmark value with badge styling)
  • Updated (formatted last update timestamp)
  • Actions (Edit/Delete links)

Benchmarks List Page

Location: src/app/dashboard/benchmarks/list/page.tsx

  • Server component for the benchmarks list view
  • Fetches all benchmarks with related dimension and industry data
  • Requires authentication (redirects to login if not authenticated)
  • Shows empty state when no benchmarks exist
  • Displays error messages when database operations fail
  • Includes breadcrumb navigation
  • Links to main benchmarks management page

Main Benchmarks Page Update

Location: src/app/dashboard/benchmarks/page.tsx

  • Added "View All Benchmarks" button to navigate to list view
  • Maintains existing "Select Assessment" workflow
  • Provides dual navigation patterns for user flexibility

3. Test Coverage

Unit Tests

Location: src/app/dashboard/benchmarks/__tests__/benchmarks-list-table.test.tsx

  • Total Tests: 13 (all passing)
  • Coverage Areas:
    • Rendering with all benchmarks
    • Displaying dimension codes and names
    • Displaying industry information
    • Displaying formatted benchmark values
    • Displaying formatted dates
    • Edit and Delete button presence
    • Delete confirmation prompt
    • Successful deletion with API call
    • Error handling during deletion
    • Button disabled state during deletion
    • Empty benchmarks array handling
    • Missing relations handling
    • Edit link URLs validation

API Unit Tests

Location: src/app/api/benchmarks/__tests__/api-benchmark-routes.test.ts

  • Total Tests: 44 (all passing)
  • GET /api/benchmarks Tests: 6
    • Returns all benchmarks with authentication
    • Returns 401 if not authenticated
    • Handles database errors gracefully
    • Orders benchmarks by created_at descending
    • Filters by industry_id
    • Filters by dimension_id
  • GET /api/benchmarks/[id] Tests: 4
    • Returns single benchmark by id
    • Returns 401 if not authenticated
    • Returns 404 if not found
    • Handles database errors gracefully
  • Additional tests for POST, PATCH, DELETE, and bulk operations

E2E Tests

Location: e2e/feature-benchmark-crud.test.ts

  • New Tests Added: 7
  • Test Coverage:
    • Admin can navigate to all benchmarks list view
    • Admin can view benchmarks in list table
    • Admin can view benchmark count in list view
    • Benchmarks list table displays dimension and industry information
    • Benchmarks list has breadcrumb navigation
    • Benchmarks list has "Manage by Assessment" button
    • Table structure and headers validation

4. Database Schema

Table: benchmarks Columns:

  • id (UUID, primary key)
  • dimension_id (UUID, foreign key to dimensions table)
  • industry_id (UUID, foreign key to industries table)
  • value (DECIMAL(10, 2), required)
  • created_at (timestamp)
  • updated_at (timestamp)

Row Level Security:

  • Users can view benchmarks for dimensions in assessments they created
  • Users can create benchmarks for their assessment dimensions
  • Users can update benchmarks for their assessment dimensions
  • Users can delete benchmarks for their assessment dimensions

5. Key Features

Responsive Design

  • Mobile-first approach
  • Adaptive table layout
  • Hidden columns on smaller screens
  • Touch-friendly action buttons

Data Display

  • Dimension name and code prominently displayed
  • Industry name clearly shown
  • Benchmark value with visual badge
  • Last updated timestamp
  • Fallback text for missing data ("Unknown Dimension", "Unknown Industry", "—")

User Actions

  • Edit: Navigate to benchmark management page for specific assessment/industry
  • Delete: Remove benchmark with confirmation dialog
  • Navigation: Breadcrumbs and buttons for easy movement between views

Error Handling

  • Authentication errors (redirect to login)
  • Database errors (display error message)
  • Empty states (helpful messaging with CTAs)
  • Missing data (graceful fallbacks)

User Feedback

  • Success messages (auto-dismiss after 3 seconds)
  • Error messages (persistent until dismissed or new action)
  • Loading states (disabled buttons with "Deleting..." text)
