AWS Provider Test Suite

Version: 1.0 Last Updated: 2026-01-07 Status: Production Ready (Mock Mode - No Real API Calls)

---

Overview

The AWS Provider Test Suite provides comprehensive testing coverage with 51 deterministic tests running in mock mode. All tests use pre-defined AWS API response fixtures with no external API calls required.

Test Structure: 14 unit tests + 37 integration tests = 51 total tests

Test Breakdown

Unit Tests (14 tests)

File: tests/unit/test_utils.nu

Tests utility functions for validation and parsing:

• Instance ID format validation (i-1234567890abcdef0)
• IPv4 address extraction and validation (10.0.1.100)
• Instance type validation (t3.micro, m5.large, c5.xlarge)
• Availability zone validation (us-east-1a, eu-west-1b)
• EBS volume ID validation (vol-12345678)
• Volume state validation (creating, available, in-use, deleting)
• CIDR block format validation (10.0.0.0/16)
• Volume type validation (gp2, gp3, io1, io2, st1, sc1)
• ISO 8601 timestamp parsing (2025-01-07T10:00:00.000Z)
• Server state validation (pending, running, stopped, terminated)
• Security group ID validation (sg-12345678)
• Memory specification validation (512 MB, 1 GB, 4 GB)
• vCPU count validation (1, 2, 4, 8, 16, 32)

Result: 14/14 PASS ✓

Integration Tests (37 tests)

API Client Tests (13 tests)

File: tests/integration/test_api_client.nu

Tests AWS EC2 API client functionality:

• describe-instances returns list of reservations
• Reservation structure contains instances array
• Single instance response with all required fields
• describe-volumes list response structure
• Volume response validation (VolumeId, Size, State, AZ)
• Create instance response in pending state
• Instance type information structure
• Error response 401 (UnauthorizedOperation)
• Error response 404 (InvalidInstanceID.NotFound)
• Error response 429 (RequestLimitExceeded)
• Instance state values (running, stopped)
• Key pair information availability
• Pricing data structure validation
• Volume attachment information

Result: 13/13 PASS ✓

Server Lifecycle Tests (12 tests)

File: tests/integration/test_server_lifecycle.nu

Tests server lifecycle operations:

• List servers returns EC2 instances
• Server info has required fields (InstanceId, Type, State, IPs)
• Hostname tag lookup matches expected values
• Server state validation (running vs stopped)
• Public IP address presence and format
• Create instance response validation
• Instance type details (vCPU count, memory)
• Availability zone information
• Block device mapping (attached volumes)
• Security group assignment
• Launch time recording
• Multiple instance state differentiation

Result: 12/12 PASS ✓

Pricing Tests (12 tests)

File: tests/integration/test_pricing.nu

Tests pricing and cost estimation:

• Pricing data has instance type field
• Pricing includes on-demand rate
• Pricing includes reserved rate (lower than on-demand)
• Instance type filtering (t3.micro, t3.small, t3.medium)
• Price scaling (larger instances cost more)
• vCPU correlation with pricing
• Memory format specification (GB units)
• Monthly cost calculation (hourly rate times 730)
• All pricing entries complete
• Volume pricing available
• gp3 volume IOPS and throughput specifications
• Volume cost estimation (per GB-month)

Result: 12/12 PASS ✓

Mock Data

Mock Responses File

File: tests/mocks/mock_api_responses.json

Contains realistic AWS EC2 API response fixtures:

• describe_instances_list: Two test instances (one running, one stopped)
• describe_instances_single: Single running instance with full details
• describe_volumes_list: Two test volumes (one in-use, one available)
• describe_volumes_single: Single volume with attachment information
• create_instance_response: New instance response in pending state
• describe_key_pairs: SSH key pair listing with aws-default key
• describe_instance_types: Three instance type specifications
• error_401: Unauthorized operation error response
• error_404: Resource not found error response
• error_429: Rate limit exceeded error response
• pricing_data: Three pricing tiers (t3.micro, t3.small, t3.medium)

All responses match the actual AWS EC2 API response format.
