What it does

Gen Test is an agent skill from Artexis10/endstate-gui. Generate unit tests following project conventions. Use when the user asks to create, generate, or write tests for a file or component.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Unit testing and Test generation. It works with Tauri and Vitest. The repository describes itself as: Endstate desktop app: reinstall your apps and restore your settings on a fresh Windows PC, from one portable file. Free, open source. Built with Tauri (React + Rust). The licence is Apache-2.0.

When your agent uses it

  • The user asks to create
  • Write tests for a file

Example prompts

  • “/gen-test”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read the source file to understand exports, types, and behavior
  2. Check for an existing test file co-located next to the source (e.g., foo.ts → foo.test.ts)
  3. Generate tests following project conventions (see below)
  4. Run the new tests to verify they pass: npx vitest run

What it can do on your machine

Read from SKILL.md and the folder at commit 4bcd1ac. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gen Test loads about 661 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 227 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~661

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Generate unit tests following project conventions. Use when the user asks to create, generate, or write tests for a file or component.

Generate unit tests for the specified file or component.

Input: A file path, component name, or utility function to test. If omitted, infer from conversation context.

Steps

  1. Read the source file to understand exports, types, and behavior
  2. Check for an existing test file co-located next to the source (e.g., foo.ts → foo.test.ts)
    • If it exists, read it and add new tests rather than replacing
  3. Generate tests following project conventions (see below)
  4. Run the new tests to verify they pass: npx vitest run <test-file>

Project Conventions

  • Test files are co-located: src/lib/foo.ts → src/lib/foo.test.ts, src/components/app/bar.tsx → src/components/app/bar.test.tsx
  • Framework: Vitest + React Testing Library (jsdom environment)
  • Import from vitest: describe, it, expect, vi, beforeEach, afterEach
  • For React components, import render, screen, fireEvent, within from @/test/test-utils (NOT directly from @testing-library/react)
  • Query priority: getByRole → getByLabelText → getByText. Avoid getByTestId unless semantic queries fail. Never use snapshots.
  • Use @/ path alias for imports (maps to ./src/)
  • framer-motion is auto-mocked in vitest.setup.ts — no special handling needed
  • localStorage is auto-mocked — use helpers from @/test/localStorage-helpers if needed
  • For Tauri bridge mocking, use @/test/tauri-bridge-mock
  • Group related tests in describe blocks
  • Test names should describe behavior, not implementation

Example Structure

typescript
import { describe, it, expect, vi, beforeEach } from 'vitest';
import { render, screen, fireEvent } from '@/test/test-utils';
import { MyComponent } from './my-component';

describe('MyComponent', () => {
  it('renders the primary action button', () => {
    render(<MyComponent />);
    expect(screen.getByRole('button', { name: /action/i })).toBeInTheDocument();
  });

  it('calls onSubmit when clicked', async () => {
    const onSubmit = vi.fn();
    render(<MyComponent onSubmit={onSubmit} />);
    fireEvent.click(screen.getByRole('button', { name: /submit/i }));
    expect(onSubmit).toHaveBeenCalledOnce();
  });
});

Guardrails

  • Keep tests focused on behavior, not implementation details
  • Don't mock what you don't have to
  • Don't add tests for trivial pass-through props
  • If the source file uses shadcn/ui components, query by role (they use Radix primitives with proper ARIA)
