Features

Hook Execution Wrappers - Executes hooks inside a minimal React component to simulate a real lifecycle and access hook state.
Custom Hook Testing - Implements a specialized harness for verifying the state transitions and return values of custom hooks in isolation.
Hook Return Value Tracking - Captures and tracks the latest return values of hooks during render cycles for external inspection.
Hook Mocking Utilities - Provides a framework for injecting props and awaiting asynchronous updates within a simulated React environment.
Test Harnesses - Implements a simulated environment (test harness) to validate hook logic without a full UI.
Headless Render Cycle Controllers - Manages the timing of hook execution and state updates to ensure predictable behavior in headless environments.
Asynchronous Polling Mechanisms - Provides polling mechanisms to wait for asynchronous state updates before running test assertions.
Asynchronous Test Handling - Provides capabilities for managing tests that rely on asynchronous hook operations and promise resolutions.
React Testing Utilities - Provides specialized utilities for unit testing React hooks in isolation by simulating a component environment.
Component Prop Injection - Allows injecting dynamic properties into a wrapper component to trigger hook re-renders and test various inputs.
Hook Property Injection - Passes custom arguments and initial values to hooks to verify behavior across different configurations.
State Update Triggering - Provides capabilities to simulate user interactions and state changes to verify that hook return values update correctly.
Hook Lifecycle Testing - Ensures that effects and cleanup functions within a hook execute correctly across all lifecycle phases.
Test State Cleanup - Includes mechanisms to clear hook state and unmount components to prevent pollution between tests.
Test Lifecycle Hooks - Provides mechanisms to unmount test components to trigger cleanup effects and hydrate for interaction.
Test Lifecycle Hooks - Automatically executes cleanup functions after tests to remove rendered hooks and prevent state leakage.
Hook State Verifications - Verifies that a hook correctly manages internal state and updates its output based on changing triggers.
State Response Testers - Utilities for verifying how hooks respond to state changes by triggering re-renders and managing cleanup.
Test-Controlled State Updates - Executes state updates and effects within a wrapper to ensure all changes finish before assertions.
