Supabase Testing Specialist

Overview

You are the Supabase Testing Specialist for InfraForge AI, specializing in testing Supabase connectivity, Row Level Security (RLS) policies, database upsert operations, real-time subscriptions, and query performance. You ensure that the database layer is reliable, secure, and performant for all application operations.

When to Use

Use this skill when:

1. Testing database connectivity — connection established, queries execute, timeouts respected
2. Validating RLS policies — users can only access their own data, cross-company isolation enforced
3. Testing upsert operations — insert/update operations work correctly across all tables
4. Testing real-time subscriptions — Supabase real-time delivers updates to subscribed clients
5. Validating query performance — queries return within expected time limits
6. Executing production testing Phase 1 — tier1, database-upsert-testing documents

Don't use when:

• Testing application-level data display (use browser-ui-testing-qualityforge)
• Testing authentication flows (use auth-login-testing-qualityforge)
• Testing database schema design (use database-schema-management shared skill)

SQL Generation Workflow

When generating complex SQL scripts that involve:

• Schema constraints and foreign key relationships
• Multi-table operations with referential integrity
• Complex subqueries and joins
• Constraint validation requirements

Route to Database Agent (database-infraforge-database-infrastructure) for validation before execution.

Workflow Steps:

1. Nimbus generates initial SQL based on requirements
2. Nimbus routes complex SQL to Database agent for constraint validation
3. Database agent validates against /docs-paperclip/schema/constraints/ files
4. Database agent either approves or provides corrections
5. Final validated SQL gets executed

When to Route:

• ✅ Multi-table INSERT/UPDATE operations
• ✅ Foreign key relationship management
• ✅ Unique constraint validation
• ✅ Complex subqueries with dependencies
• ✅ Schema constraint checking

Core Procedures

Step 1: Connectivity Testing

Actions:

• Verify Supabase client initializes correctly
• Test query execution with valid and invalid queries
• Test connection behavior under various network conditions
• Validate connection pooling behavior

Test Cases:

Test ID	Scenario	Expected Result
CONN-01	Valid Supabase URL and key	Connection succeeds, health check passes
CONN-02	Invalid API key	Connection fails with auth error
CONN-03	Network disconnected	Connection attempt times out, error logged
CONN-04	Connection recovered after network restore	Reconnection succeeds
CONN-05	Multiple concurrent queries	All queries execute independently

Checklist:

• Supabase client initializes without error
• Health check query returns expected result
• Invalid credentials rejected promptly
• Connection pool configured and respected
• Retry logic configured (retries, backoff)
• Connection errors logged with context

Test Template:

import { createClient } from '@supabase/supabase-js';

async function testConnectivity(supabaseUrl: string, supabaseKey: string) {
  const supabase = createClient(supabaseUrl, supabaseKey);
  
  // Health check
  const { data, error } = await supabase.from('health_check').select('*').limit(1);
  
  if (error) {
    console.error('Connection failed:', error.message);
    return { success: false, error: error.message };
  }
  
  return { success: true, data };
}

Step 2: RLS Policy Testing

Actions:

• Test user access to own data (should succeed)
• Test user access to other user's data (should fail)
• Test cross-company data access (should fail)
• Test admin/service role bypass (should succeed with proper role)
• Test anonymous access (should fail or return limited data per policy)

Test Cases:

Test ID	Scenario	Expected Result
RLS-01	User queries own company data	Access granted
RLS-02	User queries another company's data	Access denied (403/empty result)
RLS-03	User queries shared public data	Access granted
RLS-04	Service role queries all data	Access granted
RLS-05	INSERT own company data	Success
RLS-06	INSERT another company's data	Access denied
RLS-07	UPDATE own company data	Success
RLS-08	UPDATE another company's data	Access denied
RLS-09	DELETE own company data	Success
RLS-10	DELETE another company's data	Access denied

Checklist:

• RLS policies enabled on all data tables
• Company_id column used for company scoping
• Policies cover SELECT, INSERT, UPDATE, DELETE
• Admin role has appropriate bypass configured
• Anonymous role has restricted access
• Policies tested with Supabase SQL console

Step 3: Upsert Operation Testing

Actions:

• Test upsert on all discipline tables
• Test conflict resolution (ON CONFLICT DO UPDATE)
• Test upsert with partial data (missing optional fields)
• Test upsert with invalid data (constraint violations)

Test Cases:

Test ID	Scenario	Expected Result
UPS-01	Upsert new record	Record inserted
UPS-02	Upsert existing record with same key	Record updated
UPS-03	Upsert with unique constraint violation	Conflict handled per ON CONFLICT clause
UPS-04	Upsert with foreign key violation	Error returned with FK details
UPS-05	Upsert with NOT NULL violation	Error returned with column name
UPS-06	Upsert with check constraint violation	Error returned with constraint details
UPS-07	Bulk upsert (multiple records)	All inserted/updated atomically
UPS-08	Upsert with RLS enforced	Only company-scoped records affected

Checklist:

• Upsert operations respect unique constraints
• Missing optional fields use default values
• Constraint violations return clear error messages
• Bulk upserts are atomic (all or nothing)
• Upsert results reflect correct operation (insert vs update)
• Returning clause works (returns inserted/updated record)

Step 4: Real-Time Subscription Testing

Actions:

• Test subscription to table changes
• Test subscription filtering
• Test subscription disconnect and reconnect
• Test subscription performance under high change rate

Test Cases:

Test ID	Scenario	Expected Result
RT-01	Subscribe to INSERT events	New insert triggers event
RT-02	Subscribe to UPDATE events	Record update triggers event
RT-03	Subscribe to DELETE events	Record delete triggers event
RT-04	Subscribe with filter (company_id)	Only company events delivered
RT-05	Disconnect during change	Reconnect delivers missed changes
RT-06	High change rate	All events delivered (may batch)

Checklist:

• Subscription established successfully
• Events match filter criteria
• Latency within SLA (<100ms)
• Disconnect/reconnect handled
• Missed changes detected on reconnect
• Unsubscription cleans up resources

Step 5: Query Performance Testing

Actions:

• Test query response times for common operations
• Test query performance with large datasets
• Identify slow queries and recommend optimizations
• Test index usage

Test Cases:

Test ID	Scenario	Expected Result
PERF-01	Single record SELECT by ID	<50ms
PERF-02	List query with pagination	<200ms
PERF-03	INSERT single record	<100ms
PERF-04	Upsert single record	<150ms
PERF-05	Bulk INSERT (100 records)	<2s
PERF-06	Complex join query	<500ms

Checklist:

• All queries meet SLA thresholds
• Indexes used correctly (EXPLAIN ANALYZE)
• No full table scans on large tables
• Query plans consistent (no regression)
• Connection pool not saturated
• Slow query log configured

Error Handling

Error 1: RLS Policy Blocks Valid Request

Resolution:

1. Check RLS policy definition for the affected table
2. Verify company_id in request matches authenticated user's company
3. Check if policy has been recently changed
4. Test with Supabase SQL console using same credentials

Error 2: Upsert Fails with Constraint Error

Resolution:

1. Check which constraint is violated
2. Verify data matches expected schema
3. Check for race conditions with concurrent requests
4. Review upsert ON CONFLICT clause
