Testing Tauri Applications

This skill covers testing strategies for Tauri v2 applications: unit testing with mocks, end-to-end testing with WebDriver, and CI integration.

Testing Approaches Overview

Tauri supports two primary testing methodologies:

1. Unit/Integration Testing - Uses a mock runtime without executing native webview libraries
2. End-to-End Testing - Uses WebDriver protocol for browser automation

Mocking Tauri APIs

The @tauri-apps/api/mocks module simulates a Tauri environment during frontend testing.

Install Mock Dependencies

npm install -D vitest @tauri-apps/api

Mock IPC Commands

import { mockIPC, clearMocks } from '@tauri-apps/api/mocks';
import { invoke } from '@tauri-apps/api/core';
import { vi, describe, it, expect, afterEach } from 'vitest';

afterEach(() => {
  clearMocks();
});

describe('Tauri Commands', () => {
  it('should mock the add command', async () => {
    mockIPC((cmd, args) => {
      if (cmd === 'add') {
        return (args.a as number) + (args.b as number);
      }
    });

    const result = await invoke('add', { a: 12, b: 15 });
    expect(result).toBe(27);
  });
