What is Compose?

Compose is LitmusCheck’s interactive test creation mode that allows you to build tests using natural language instructions while watching them execute in real-time. It provides a side-by-side view where you can see your test steps being performed on a live browser, making test creation intuitive and visual. Compose mode bridges the gap between test design and execution, enabling you to create reliable end-to-end tests without writing code manually. You describe what you want to test in plain English, and LitmusCheck translates your instructions into executable test steps.

​
Key Features

​
1. Live Visual Execution

  • Watch your test steps execute in real-time as you add them
  • See exactly how each action interacts with your application
  • Validate that your test behaves correctly before saving

​
2. Natural Language Instructions

  • Write test steps in plain English (e.g., “Click on the login button”)
  • No need to write code or memorize complex selectors
  • AI-powered element detection understands your intent

​
3. Interactive Test Building

  • Add, edit, delete, and reorder steps with drag-and-drop
  • Stop execution at any time to make changes
  • Rerun tests from the beginning to verify changes

​
4. AI-Powered Element Detection

  • Use AI prompts to find elements on the page
  • Choose between generating stable selectors or dynamic AI execution
  • Save detected elements for reuse across tests

​
5. Immediate Feedback

  • See step-by-step execution status (success, failure, pending)
  • Identify issues immediately during test creation
  • Debug and fix problems in real-time

​
How Compose Works

  1. Enter a URL: Load your application in the Compose browser
  2. Add Instructions: Select actions from the dropdown (Click, Type, Verify, etc.)
  3. Watch Execution: Each step executes immediately after being added
  4. Refine Steps: Edit, reorder, or delete steps as needed
  5. Save Test: Once satisfied, save your test for future runs

​
Use Cases

  • Rapid Test Creation: Build tests quickly without writing code
  • Visual Validation: Ensure tests work correctly before committing them
  • Exploratory Testing: Discover and document test scenarios interactively
  • Test Maintenance: Update existing tests by watching them execute and making adjustments

​
Best Practices

  • Use Stable Selectors: When AI finds elements, prefer saving them as reusable elements rather than using dynamic AI execution for better reliability
  • Test Incrementally: Add a few steps at a time and verify they work before adding more
  • Use Rerun: Regularly rerun your test from the beginning to catch regressions
  • Save Frequently: Save your work periodically to avoid losing progress
