SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires org.jetbrains.compose.ui:ui-test-junit4-desktop, org.jetbrains.kotlinx:kotlinx-coroutines-core, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a way to visually verify Compose UI components by rendering them to images, allowing for rapid UI iteration and visual feedback without the need for running the full application.

Core Features & Use Cases

  • Visual Verification: Render Compose components to images for immediate visual feedback.
  • Rapid UI Iteration: Use the Skill to quickly iterate on UI designs and verify changes.
  • JVM Target Required: Must use a JVM or Desktop target for UI testing due to Android limitations.

Quick Start

Use the verifying_compose_ui skill to render the Compose component 'MyComponent.kt' as an image.

FAQPage Schema
How do I visually verify Compose UI components without running the full application?▼

You can visually verify Compose UI components by rendering them directly to images using a JVM-based Kotlin REPL. This approach provides immediate visual feedback for UI layout and behavior without requiring a full app deployment.

Can I render Composable functions to images for rapid UI iteration?▼

Yes, rendering Composable functions to images allows for rapid UI iteration. By visualizing Compose UI components as static images, you can quickly verify design changes and layout behavior during development.

Do I need a specific build target to use a JVM REPL for Compose UI testing?▼

Yes, you must use a JVM or Desktop target for Compose UI testing. This requirement exists because rendering Compose components to images via a JVM-based REPL currently faces limitations with Android targets.

What dependencies are required to render Compose components to images?▼

Rendering Compose components requires the Kotlin Multiplatform Compose UI testing libraries. Specifically, you need the ui-test-junit4-desktop library for desktop rendering and kotlinx-coroutines-core for asynchronous operations.

What are the limitations of visual verification for Compose UI on Android?▼

The primary limitation is that visual verification via a JVM-based REPL does not support Android targets. You must switch to a JVM or Desktop target to successfully render and verify your Compose UI components as images.
