@wdio/native-spy

Minimal mock function implementation for WebdriverIO Native Desktop Services.

Overview

This package provides a lightweight mock/spy implementation (fn()) for use in Electron and Tauri desktop testing scenarios where @vitest/spy cannot be bundled directly into the application context.

Usage

import { fn } from '@wdio/native-spy';

// Create a mock function
const mock = fn();

// Set return values
mock.mockReturnValue('hello');
console.log(mock()); // 'hello'

// Track calls
mock('world');
console.log(mock.calls.length); // 1
console.log(mock.calls[0].args); // ['world']

API

fn<T>(implementation?)

Creates a mock function with the optional implementation.

Mock Methods

• mockReturnValue(value) - Set return value
• mockReturnValueOnce(value) - Set return value for next call
• mockResolvedValue(value) - Set resolved value (for async functions)
• mockResolvedValueOnce(value) - Set resolved value for next call
• mockRejectedValue(reason) - Set rejection error
• mockRejectedValueOnce(reason) - Set rejection error for next call
• mockImplementation(fn) - Set implementation function
• mockImplementationOnce(fn) - Set implementation for next call
• mockClear() - Clear call history
• mockReset() - Reset to initial state
• mockRestore() - Restore original implementation
• mockName(name) - Set mock name
• getMockName() - Get mock name

Mock Properties

• calls - Array of call information
• results - Array of call results
• invocationCallOrder - Order of invocations
• instances - Array of instances (for constructor mocks)
