Test Infrastructure - hermes-mobile

This document describes the test infrastructure, philosophy, architecture, and feature coverage for the hermes-mobile Jetpack Compose Android application.

Test Philosophy

The test suite utilizes opaque-box JVM-based integration and E2E tests that drive the ViewModels directly, bypassing the UI rendering layer, with mocked Retrofit responses using Mockk for service stubs. This allows testing the application logic, optimistic UI state changes, API integration pathways, and navigation flows synchronously and reliably without requiring an Android emulator or device.

Feature Inventory

Feature 1: Skills Management Screen

• Listing: Fetches and lists available agent skills.
• Category/Description Display: Shows skill details (category, optional description, name).
• Toggle Success: Modifies a skill's state optimistically, sends API request, and confirms success state.
• Toggle Failure Revert: Handles API failure, displays toast, and reverts the state optimistically.
• Refresh: Supports reloading/refreshing the list of skills from the API.

Feature 2: Cron Jobs Screen

• Listing: Fetches and lists all configured cron jobs.
• State/Last Run/Next Run Display: Displays status fields (state, last_run_status, next_run).
• Pause Action: Optimistically transitions a job's state to "paused", sends API request.
• Resume Action: Optimistically transitions a job's state to "active", sends API request.
• Trigger Action: Triggers a job immediately and displays a success toast.
• Delete Action: Optimistically removes a job from the list and sends a DELETE API request.
• Refresh: Supports reloading/refreshing the list of cron jobs.

Feature 3: Navigation Drawer

• Transitions: Simulates moving between top-level destinations (Chat, Skills, Cron Jobs) via the Material3 Navigation Drawer using the Custom NavigationController and its backStack.

Test Architecture

• Test Runner:
  • Main Test suite command: nix develop --command ./gradlew test
  • Style checking command: nix develop --command ./gradlew ktlintCheck
• Test Case Format:
  • JUnit 4 / JUnit Platform JVM tests implemented in Kotlin.
  • Mocking library: Mockk for mock objects, static mocks, and API endpoints.
• Directory Layout:
  • app/src/test/java/com/m57/hermescontrol/E2eIntegrationTest.kt contains the complete end-to-end integration test suite.

Tier 4 Scenario: Complete User Journey

The Tier 4 scenario is implemented in testFullUserSessionFlow() which simulates a complete user session:

1. Connect: User enters coordinates and token, successfully authenticating/connecting.
2. Open Drawer & Navigate: Transitions from Chat to Skills.
3. Toggle a Skill (Optimistic Update -> API Failure -> Toast/Revert):
   • User toggles a skill.
   • UI updates optimistically to the new state.
   • Retrofit API returns a simulated HTTP 500 error.
   • The state is reverted back to original, and an error Toast message is shown.
4. Navigate to Cron Jobs: User navigates from Skills to Cron Jobs.
5. Trigger Cron Job:
   • User triggers a cron job.
   • Retrofit API returns a success code.
   • Success Toast message is displayed and verified.
