Test Plan - Wallet API Automation

Objective

The objective of this test plan is to validate the correctness, reliability, and robustness of the Wallet Transaction API, with a primary focus on:

  • POST /wallet/{walletId}/transaction

This includes ensuring accurate financial calculations, proper error handling, and consistent system behavior under various scenarios.

Project Strategy

  • Data-Driven Testing (DDT): All transaction scenarios are driven by external JSON fixtures (test/fixtures/transactions.json).
  • Mocking: A local mock server is used to simulate API responses and service latencies.
  • Dynamic Identification: userId and walletId are discovered at runtime via authentication and user info endpoints.

Execution Strategy

Tests are designed to run against:

  • A mock server generated from the OpenAPI spec
    OR
  • A real API endpoint (configurable via environment variable)

Implemented Test Cases (13 Cases)

Area: General Wallet Operations

ID Test Case Description Expected Result
TC-01 Wallet Metadata Retrieve GET /wallet/{id} 200 OK, returns correct walletId and currencyClips array.
TC-02 History Pagination (P1) Retrieve history for page 1 200 OK, returns transaction list and totalCount.
TC-03 History Pagination (P2) Retrieve history for page 2 200 OK, validates pagination logic.
TC-04 Specific Tx (EUR) Create EUR Tx and retrieve by ID 200 OK, retrieved data matches the created transaction.
TC-05 Specific Tx (USD) Create USD Tx and retrieve by ID 200 OK, validates multi-currency retrieval.

Area: Transaction Processing (Data-Driven)

ID Test Case Dataset Expected Result
TC-06 Happy Path Credit EUR 100.50 Credit 200 OK, status 'finished' and outcome 'approved'.
TC-07 Happy Path Debit EUR 50.25 Debit 200 OK, balance deduction verified.
TC-08 Happy Path Credit USD 500.00 Credit 200 OK, status 'finished' or 'pending'.
TC-09 Happy Path Debit USD 25.00 Debit 200 OK, successful cross-currency support.
TC-10 Happy Path Credit AED 1000.00 Credit 200 OK, validates exotic currency support.
TC-11 Unauthorized Access Missing Token (USD) 401 Unauthorized returned.
TC-12 Insufficient Funds GBP 10000.00 Debit 200 OK, status 'finished' and outcome 'denied'.
TC-13 Idempotency Validation Duplicate Request 200 OK, returns same transactionId for duplicate keys.

Crucial Unimplemented Test Cases

Limited to 5 prioritized items as per requirements.

ID Test Case Priority Reason for Deferred Implementation
UT-01 30-Min Auto Rejection High Requires long-duration wait or time-mocking to verify pending tx rejection.
UT-02 Race Condition Testing High Requires high-concurrency tools (K6/JMeter) to verify wallet locks during simultaneous hits.
UT-03 Service Unavailable (503) High Requires circuit-breaker mocking to verify system resilience when backend fails.
UT-04 Precision and Rounding High Requires complex decimal math validation (e.g., 0.1 + 0.2) to prevent rounding leaks.
UT-05 Balance Integrity High Requires stateful validation of ledger sum vs. balance across 100+ sequential operations.

Verification Strategy

  • Client: Supertest (HTTP assertions)
  • Validation:
    • Status Code matching.
    • JSON Body structure (Presence of transactionId, status).
    • Business logic matching (Outcome approved/denied).
