How to use the Android Testing Setup agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The testing-setup skill is a set of instructions and reference files that teaches an AI agent how to analyse and build a testing strategy for an Android app. It is aimed at Android developers who want the agent to review their Gradle test setup and add missing pieces such as JUnit, Espresso or Compose testing APIs. After this guide you will know what the skill does, how to install it, how to phrase requests that trigger it, and what to check before letting it change your build files.
Android Testing Setupandroid/skills · Apache-2.0 Download the skill Quick start
- 1Download the ZIP. Download the testing-setup ZIP from this page.
- 2Unzip into a skills folder. Unzip it into ~/.claude/skills/ for personal use, or into your project's .claude/skills/ folder for one project.
- 3Or upload in the Claude apps. Go to Settings → Capabilities → Skills and upload the ZIP if you use the Claude apps.
- 4Open your Android project. Make sure the project uses Gradle, with libs.versions.toml or build files.
- 5Ask for an analysis first. Request a report of the current testing setup so you can review what is already in place.
- 6Review proposed changes. Check each dependency and configuration change before applying it, since they can break the build.
- 7Run your build and tests. Build the project and run the tests to confirm the new setup works.
What the testing-setup skill makes the agent do
When the skill is active, the agent first reviews your project's build files, including libs.versions.toml, to see which testing libraries and dependency injection tools are already in use. It then produces a Markdown report describing the current testing setup.
After the analysis, the skill guides the agent to install and configure missing pieces. The source names JUnit4, JaCoCo, Espresso or Compose testing APIs, Robolectric, Dropshots, Mockk and UI Automator, along with Hilt or Koin setup and fakes for dependencies. The agent follows step-by-step guidance bundled with the skill, so it does not have to rediscover these conventions each time.
- Analyse existing dependency injection, unit test, mocking and UI test libraries
- Write a Markdown report of the current setup
- Install and configure missing test frameworks and screenshot tools
- Create fakes and test scaffolding such as Hilt or Compose UI test setup
Install the testing-setup skill from ZIP or the Claude apps
Download the ZIP for the skill from this page. Then choose one of the two install routes described in the source material.
For a personal setup, unzip the download into ~/.claude/skills/. To limit the skill to a single project, unzip it into that project's .claude/skills/ folder instead.
In the Claude apps, you can instead upload the ZIP under Settings → Capabilities → Skills.
- Personal install: unzip into ~/.claude/skills/
- Project install: unzip into the project's .claude/skills/
- Claude apps: Settings → Capabilities → Skills, then upload the ZIP
Trigger the skill with natural requests
You do not need a special command. Describe what you want in plain language while working in your Android project, and the agent can use the skill when the request matches its purpose: analysing or creating a test strategy, installing testing libraries, setting up test infrastructure, or creating harnesses for unit, UI, screenshot or end-to-end tests.
Be specific about your app and any preferences. The skill says to respect the current testing stack unless you specify otherwise, and to ask before choosing a dependency injection framework for multiplatform apps.
- "Analyse the testing setup in this Android project and write a Markdown report."
- "Add Hilt testing scaffolding to my ViewModel tests."
- "Set up Compose UI tests and screenshot tests for this app, following the existing libraries."
What the skill does with each kind of test
For unit tests, the skill asks for a task to add or review tests in files that contain business logic, such as ViewModels, Repositories and DAOs. It says not to create unit tests for Activities, Compose layouts or dependency injection configuration files.
For UI tests, Espresso or Compose UI tests go in the test sourceset because they run with Robolectric. Instrumented tests go in androidTest. For screenshot tests, the source distinguishes AGP test suites on 9.5.0-alpha03 or higher, which it recommends, from the legacy standalone plugin on lower AGP versions, which it says is deprecated. The agent should not upgrade AGP as part of this setup.
- Unit tests: ViewModels, Repositories, DAOs
- UI tests: test sourceset (Robolectric) or androidTest for device tests
- Screenshot tests: follow the AGP version check before choosing a setup
- Mockk is installed only if a mocking framework is clearly necessary
Safety notes before the agent changes your build
This skill modifies Gradle dependencies and test configuration. The source says that can break builds if applied blindly, so review every change the agent proposes before accepting it, and run your build afterwards.
The skill runs no scripts and uses no network access, according to the item details. The bundled reference files cover Compose screenshot testing, Hilt testing and common Compose testing patterns.
- Review diffs to build.gradle and libs.versions.toml before committing
- Keep the agent's Markdown report to compare with later changes
- Do not use the skill on non-Android projects; the guidance is specific to Android and Gradle
What people use it for
- Auditing an existing Compose or View-based app to see which testing libraries are already in use
- Adding Hilt testing setup and a test runner to an app with instrumented tests
- Creating Compose UI test scaffolding that follows the project's existing libraries
- Setting up screenshot tests after checking the project's Android Gradle Plugin version
- Writing unit tests for ViewModels and Repositories with fakes for platform dependencies
Frequently asked questions
What is the testing-setup skill for?
It is an agent skill for Android projects that analyses the existing testing setup, produces a Markdown report, and then installs and configures missing test libraries and infrastructure. It covers unit tests, UI tests, screenshot tests and end-to-end tests.
How do I install the Android testing-setup skill?
Download the ZIP from this page and unzip it into ~/.claude/skills/ for personal use, or into a project's .claude/skills/ folder. In the Claude apps, you can upload the ZIP under Settings → Capabilities → Skills.
What do I need before using this skill?
You need an Android project that uses Gradle, with libs.versions.toml or build files. For screenshot testing, the agent checks your Android Gradle Plugin version, so know which version you use.
Does the testing-setup skill run scripts or use the network?
According to the item details, the skill runs no scripts and uses no network access. It does modify Gradle dependencies and test configuration, so review its changes before building.
Can I use this skill for a Flutter, React Native or other non-Android project?
No. The guidance is specific to Android and Gradle builds, so it is not suitable for non-Android projects.
Which libraries can the skill install?
The source names JUnit4, JaCoCo, Espresso, Compose testing APIs, Robolectric, Dropshots, Mockk, UI Automator, and Hilt or Koin for dependency injection. It installs these only when they fit your project's existing stack.

Our verdict
The testing-setup skill suits Android developers who want an agent to audit their test setup and add consistent test scaffolding, especially Hilt or Compose UI tests. Skip it for non-Android projects, or if you are not prepared to review Gradle and test configuration changes before they are applied.
