Detox Copilot
A flexible plugin that drives your tests with human-written commands, enhanced by the power of large language models (LLMs). While originally designed for Detox, Detox Copilot can be extended to any other testing frameworks.
It provides clear APIs to perform actions and assertions within your tests while interfacing with an LLM service to enhance the testing process.
Quick Demo
Here's an example of how Copilot runs over a Detox test case:
The test case is written in a human-readable format, and Copilot translates it into Detox actions on the fly.
Not just Detox! Copilot can be extended to any other testing frameworks.
API Overview
High-level overview of the API that Detox Copilot exposes:
/**
* Initializes the Copilot with the given configuration.
* Must be called before any other Copilot methods.
* @param config The configuration for the Copilot.
*/
init: (config: Config) => void;
/**
* Checks if the Copilot has been initialized.
* @returns True if the Copilot has been initialized, false otherwise.
*/
isInitialized: () => boolean;
/**
* Start the Copilot instance.
* @note Must be called before each flow to ensure a clean state (the Copilot uses the operations history as part of
* its context).
*/
start: () => void;
/**
* Finalizes the flow and optionally saves temporary cache data to the main cache.
* If `isCacheDisabled` is true, the temporary cache will not be saved. False is the default value.
* @param isCacheDisabled
* @note This must be called after the flow is complete.
*/
end: (isCacheDisabled?: boolean) => void;
/**
* Performs a testing operation or series of testing operations in the app based on the given `steps`.
* @returns The result of the operation(s), which can be a single value or an array of values for each step.
* @example Tap on the login button
* @example Scroll down to the 7th item in the Events list
* @example The welcome message should be visible
* @example The welcome message text should be "Hello, world!"
* @example [
* 'Tap on the login button',
* 'A login form should be visible',
* ]
*/
perform: (steps: string | string[]) => Promise<any | any[]>;
Additional Note
In addition to the operations history, Copilot maintains a repository-level cache. If you need to ignore the current cache for any reason (e.g., when adding an action to the testing framework driver), you can set the environment variable COPILOT_OVERRIDE_CACHE
to "true" before running your tests. This will ensure that the current cache is not taken into consideration and will override the existing one.
export COPILOT_OVERRIDE_CACHE=true
If you want to disable the override after setting it to "true" and revert to using the cache, you can set COPILOT_OVERRIDE_CACHE
to "false"
export COPILOT_OVERRIDE_CACHE=false
Integration with Testing Frameworks
Detox Copilot requires two main components to work:
Prompt Handler
An adapter that interfaces with the LLM service to generate actions based on the provided prompts. For example, GPT, Gemini, Sonnet or any other LLM service.
PromptHandler
Interface
/**
* Sends a prompt to the AI service and returns the response.
* @param prompt The prompt to send to the AI service.
* @param image Optional path to the image to upload to the AI service that captures the current UI state.
* @returns The response from the AI service.
*/
runPrompt: (prompt: string, image?: string) => Promise<string>;
/**
* Checks if the AI service supports snapshot images for context.
*/
isSnapshotImageSupported: () => boolean;
Testing Framework Driver
An adapter that interfaces with the testing framework to execute the generated actions. For example, Detox, Appium, Espresso, XCTest or any other testing framework.
In order for Copilot to work with the testing framework, the driver provides the API catalog and the JS context to execute the generated actions.
TestingFrameworkDriver
Interface
/**
* Takes a snapshot of the current screen and returns the path to the saved image.
* If the driver does not support image, return undefined.
*/
captureSnapshotImage: () => Promise<string | undefined>;
/**
* Returns the current view hierarchy in a string representation.
*/
captureViewHierarchyString: () => Promise<string>;
/**
* The available API methods of the testing framework.
*/
