  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by TencentBlueKing on GitHub. Read the source before you install it.

Installation

Install the Unit Testing AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/TencentBlueKing/bk-ci.git /tmp/bk-ci
mkdir -p .claude/skills
cp -r /tmp/bk-ci/ai/skills/unit-testing .claude/skills/unit-testing
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Unit Testing in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Unit Testing on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Unit Testing is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

单元测试

适用场景

  • 编写 Service / DAO / 工具类单元测试
  • Mock 外部依赖和边界条件
  • 验证正常路径、异常路径和回归场景
  • 采用 TDD 或补测试防回归

不适用场景

  • 集成测试、端到端测试
  • 只是实现业务逻辑,不准备补测试
  • 只是排查运行环境问题

快速指导

  1. 这个 skill 关注的是 BK-CI 项目里的单元测试写法,不是测试理论总览。
  2. 测试先保证意图清晰,再考虑覆盖率;重点是关键分支和回归风险。
  3. 常见模式仍然是 AAA、Mock 外部依赖、显式断言结果和交互。
  4. 写测试前先确认你测的是业务规则,不是把实现细节机械复述一遍。
  5. 如果测试涉及后端接口或服务结构,再联动看 backend-microservice-development

高信号规则

  • 正常路径和失败路径都要有代表性覆盖
  • Mock 应该服务于隔离边界,而不是掩盖设计问题
  • 测试命名要能直接表达行为和预期

关键陷阱

  • 只测 happy path
  • Mock 过度,导致测试几乎失去行为价值
  • 断言太弱,只证明代码跑过,没有证明结果正确

Frequently asked questions

What does the Unit Testing AI skill do?

为 BK-CI 代码编写单元测试时使用,例如 JUnit5、MockK、测试组织、依赖 Mock、异常校验和 TDD 场景。当用户要补测试或用测试驱动实现时优先使用。

Why use Unit Testing on TypingMind?

Because you install it once and use it with any model. Unit Testing is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Unit Testing in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/TencentBlueKing/bk-ci/tree/master/ai/skills/unit-testing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Unit Testing?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Unit Testing?

As many as you like. As long as a model supports skills, you can use Unit Testing with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Unit Testing AI skill free?

It is published on GitHub by TencentBlueKing. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
