HTTP Mock Infrastructure and API Integration Testing - Next Steps

What We've Accomplished​

  1. HTTP Mock Infrastructure

    • Built a robust HTTP mocking framework for intercepting fetch calls
    • Implemented pattern matching for mock responses based on URL and method
    • Added flexible configuration options for mock responses
    • Added functionality to record and inspect requests
    • Fixed compiler errors related to the HTTP mock implementation
    • Added enhanced features:
      • Delay simulation for testing timeout/loading scenarios
      • Sequence-based responses for sequential API calls
      • Request content validation for verifying request payloads
      • Improved request recording for inspection
      • Network failure simulation for error handling tests
      • Realistic error response generation with proper HTTP status codes

  2. Test Configuration

    • Set up proper cargo.toml configuration for WASM testing
    • Created test scripts setup for running WebAssembly tests
    • Added test configuration for browser-based testing
    • Created proper test organization

  3. Integration Tests

    • Implemented authentication API integration tests:
      • Login with successful and failed authentication
      • Registration flow
      • Delayed response testing
    • Implemented scenario API integration tests:
      • CRUD operations (Create, Read, Update, Delete)
      • Sharing functionality
    • Added tests for error responses and network failures

  4. Codebase Fixes

    • Fixed HTML syntax in seasonality_config.rs
    • Added missing Datelike trait import in financial_scenario.rs
    • Fixed online detection in scenarios.rs
    • Fixed ownership issues in HTTP mock interceptor
    • Added proper module organization for testing

Next Steps​

  1. Testing Infrastructure

    • Set up proper CI environment for automated WebAssembly testing
    • Add more helper functions to simplify test setup and cleanup
    • Add more robust request body and header extraction in the HTTP mock
    • Integrate with test coverage tools

  2. Additional Tests

    • Add more complete auth integration tests:
      • Email verification flow
      • Password reset flow
      • Profile update flow
    • Add tests for data synchronization between local and cloud storage:
      • Offline/online sync transitions
      • Conflict resolution

  3. Enhanced Features

    • Add support for dynamic response generation based on request content
    • Add more sophisticated scenario testing with chained API calls
    • Add support for GraphQL API testing

  4. Documentation

    • Add comprehensive inline documentation for the API integration tests
    • Create a guide for adding new API tests
    • Add examples for common testing patterns

Detailed Implementation Plan​

1. Set Up CI for WebAssembly Testing​

# .github/workflows/wasm-tests.yml
name: WebAssembly Tests

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install wasm-pack
        run: curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
      - name: Run tests
        run: ./run_http_mock_test.sh

2. Additional API Testing​

Complete additional tests for the following API flows:

  • Auth: Email verification, Password reset, Profile updates
  • Sync: Online/Offline transitions, Conflict resolution
  • Additional error cases and edge scenarios

3. Future Enhancements​

  • Add support for testing WebSockets (particularly useful for real-time notifications)
  • Add support for file upload simulations
  • Add performance measurement and benchmarking capabilities
