Organizing Test Source Sets

Q: What is a Claude Code skill and how does the Organizing Test Source Sets skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Organizing Test Source Sets is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Use this skill to organize Android test source sets — `src/test/`, `src/androidTest/`, the community `src/sharedTest/` convention, and the modern KMP-style `androidHostTest` / `androidDeviceTest` split that Compose itself adopted after AGP 7.2 broke the classic `sourceSets` wiring. Includes the `testImplementation` / `androidTestImplementation` / `debugImplementation` configuration matrix per Google's `/training/testing/local-tests` and `/training/testing/instrumented-tests` pages. Use when the user asks "where do I put my tests", "test or androidTest", "sharedTest setup", "AGP 7.2 broke my sourceSets", "androidHostTest vs androidDeviceTest", "testImplementation vs androidTestImplementation vs debugImplementation", or "why is my Robolectric test in androidTest".

About this skill (catalog notes)

Organizing Test Source Sets includes explicit scope boundaries (an explicit 'when not to use' or 'out of scope' section); a dedicated installation section; 16 code blocks for direct copy-paste. At roughly 2,063 words the SKILL.md is on the longer end of the catalog distribution.

From the source SKILL.md

Where a test file lives determines which JVM runs it, which dependencies it sees, and whether it ships in the test APK. Most modules need only src/test/ and src/androidTest/. Modules that share helpers between host and device tests historically used src/sharedTest/ (a Codelab convention, not Google-documented as such), which broke on AGP 7.2+ and pushed Compose itself to the KMP-style androidHostTest / androidDeviceTest split. This skill encodes the matrix so the agent can place a test file with confidence.

What this skill does

Organizing Test Source Sets is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/organizing-test-source-sets/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks "where do I put my tests", "test or androidTest", "sharedTest setup", "AGP 7.2 broke my sourceSets", "androidHostTest vs androidDeviceTest", "testImplementation vs androidTestImplementation vs debugImplementation", or "why is my Robolectric test in androidTest".

Who uses this skill

The Organizing Test Source Sets Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 93,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
