# Test Automation as a Service: Multi-Phase Strategy

## Overview

This document outlines a multi-phase strategy for building a scalable, maintainable, and dynamic Android test automation system. The goal is to support testing at scale—ranging from dozens to tens of thousands of tests—while enabling individual development teams to own their test logic confidently.

The system is designed not just to enable automated UI tests, but to act as a test orchestration framework that can:

- Generate tests dynamically
- Support efficient test suite creation and execution
- Optimize coverage with minimal redundancy
- Allow runtime customization of test input, state, and configuration

## Summary of Phases

### **Phase 0: Ad-Hoc Testing**

- Common pattern seen in early automation efforts or tutorials
- Tests are brittle, hard to maintain
- Difficult to scale beyond ~100-200 tests

### **Phase 1: Standardization with Page Object Model (POM)**

- Introduce BasePage + Selector abstractions for cross-device/platform consistency
- Define navigation flows using a navigation graph (nodes = pages, edges = steps)
- Fluent interface pattern for clean and readable test flows
- Reuse components and improve stability
- Targets ~1,000 to ~2,000 tests

**Key Outcomes:**

- Reduced maintenance overhead
- Stable and composable test structure
- Foundation for dynamic navigation and grouped element validation

### **Phase 2: Data-Driven Tests & Dynamic Test Factories**

- Use metadata and reflection to define what each test requires
- Centralized test data service that dynamically prepares:
  - Test data
  - Test environments
  - Targeted test suites based on code changes
- Enables composable, on-demand test generation
- Replaces tags and decorators with runtime configuration
- Coverage optimization using Orthogonal Arrays (e.g. pairwise testing)

**Key Outcomes:**

- Tests generated from config or runtime context
- Faster feedback cycles by running most relevant tests first
- Easier root cause analysis in CI
- Teams can define and manage their own test scope

### **Phase 3: Test Factory of Test Factories**

- Fully leverage standardized infrastructure from Phases 1–2
- Enable AI and/or rule-based helpers to:
  - Propose tests based on heuristics or code changes
  - Self-heal flaking or broken tests
  - Minimize human intervention while scaling coverage
- Libraries for setup, steps, and assertions are highly structured
- Fluent interfaces make automation predictable and parseable

**Key Outcomes:**

- Automation becomes intelligent and context-aware
- Reduced cost of test maintenance and authoring
- Human involvement focused on novel or edge-case testing

## Current State (Phase 1 MVP)

### Helper Modules Implemented:

- `BasePage.kt`: Common logic for all screens (navigation, verification, interaction)
- `Selector.kt`: Declarative wrapper around UI selectors with grouping and description
- `NavigationRegistry.kt`: Graph structure for defining navigation steps between pages
- `PageContext.kt`: Central access point to all page objects
- `BaseTest.kt`: Test rule harness including Compose + Retry rules

**Why this matters:**
These modules abstract away repetitive test logic and create a clean DSL-like interface for writing readable, robust, and maintainable UI tests.

```kotlin
on.settingsPage.navigateToPage()
   .mozVerifyElementsByGroup("requiredForPage")
```

## How This Enables the Future

- Pages describe their _structure_ via selectors
- Navigation is described declaratively
- Test code focuses only on _what to test_, not _how to get there_
- Data-driven factories can then define _what to test_ programmatically

## Low-Level Developer Guidelines

### Writing a New Test

- Extend `BaseTest`
- Use `on.<Page>.navigateToPage()` to transition
- Use `.mozVerifyElementsByGroup("...group...")` to check structure
- Use `.mozClick(selector)` or define `NavigationStep.Click()` to interact

### Adding a New Page

- Create new object that extends `BasePage`
- Implement `mozGetSelectorsByGroup()`
- Register all navigation edges in `init {}` block

### Creating a Dynamic Test

- Define input data and selectors declaratively
- Feed test data into a factory that builds navigation + verification steps

## Final Thoughts

This framework is not just about making UI tests easier. It’s about enabling:

- Reusable automation primitives
- Team autonomy
- Data- and AI-assisted test generation
- Long-term maintainability

It positions test automation as a _strategic capability_, not just a tactical tool.
