E2E Testing React Native with Maestro: A Practical Guide

Tips for Reliable Tests with Maestro

Creating reliable and maintainable tests is crucial when using Maestro or any automation tool. Here are some best practices to ensure your test flows are robust:

1. Always Use testID for Interactive Elements

• Why: Using unique identifiers like testID ensures that your tests can reliably interact with UI elements, even if the text changes.
• Example:

  yaml
   
  1- tapOn:
  2    id: "add_ten"

2. Avoid Explicit Sleeps

• Why: Maestro automatically waits for elements to appear before interacting with them. Using sleep can make your tests brittle and harder to maintain.
• Best Practice: If you find yourself needing a sleep, it usually indicates that something else in the test flow is not set up correctly.

3. Keep Flows Small and Composable

• Why: Smaller flows are easier to understand, debug, and reuse. Each flow should represent one user journey.
• Example:
  • sign-in-flow.yaml: Handles sign-in logic.
  • profile-page-flow.yaml: Tests profile page functionality.

4. Reset App State
