Setting Up Test Automation

Once you’ve chosen the right tools, it’s time to organize your tests for efficiency and scalability.

Define Test Scope

Start by outlining a clear test scope for cross-platform automation. Focus on configurations that represent the majority of your users to make the most of your efforts and resources.

  • Platform Prioritization: Use usage analytics to identify the most popular platforms and devices.
  • Feature Focus: Highlight key user journeys that need cross-platform validation.
  • Performance Standards: Establish baseline performance benchmarks for each platform.

Build Test Structure

Design a test framework that’s easy to maintain. Use the page object model (POM) to keep test logic separate from platform-specific details.

Framework Components:

  • Base Classes: Develop abstract classes for shared functionality across platforms.
  • Platform Adapters: Create adapters to handle unique behaviors of different platforms.
  • Shared Utilities: Build reusable components for frequent operations.
  • Configuration Management: Define environment-specific settings and parameters.
Layer Purpose Key Components
Core Framework foundation Test runners, reporting tools
Business Application logic Page objects, test data
Platform Platform-specific code Device handlers, browser drivers
Configuration Environment setup Test parameters, credentials

After structuring your tests, integrate them with your CI/CD pipeline for automated execution.

Connect with CI/CD

Set up your CI/CD pipeline to run tests in parallel across environments, ensuring they remain isolated.

Integration Steps:

  1. Pipeline Configuration: Trigger test execution automatically when code changes are made.
  2. Environment Management: Set up dynamic provisioning for test environments.
  3. Results Analysis: Automate the analysis and reporting of test results.
  4. Failure Handling: Implement retry mechanisms for flaky tests.

Test Automation Guidelines

Multi-Layer Test Design

When constructing your test framework, organize it into distinct layers. This approach ensures your tests are easier to manage and scale over time. Each layer should focus on specific tasks while keeping its boundaries clear.

Core Testing Layers:

Layer Purpose Key Components
UI Handles UI interactions Screen elements, gestures, visual checks
Workflow Manages app workflows User journeys, data validation
Backend Focuses on backend tasks API calls, database operations
Platform-Specific Leverages device features Hardware sensors, OS capabilities

Test Case Selection

Choose test cases based on their risk level and potential impact. Prioritize scenarios that:

  • Cover essential business workflows
  • Test platform-specific functionalities
  • Address known areas of instability
  • Ensure compatibility across platforms

Risk-Based Selection Matrix:

Priority Criteria Testing Frequency
Critical Core functions, payment processing Every build
