Verified Agent Skill record

Test Smell Detection

Deep-dive audit using the full testsmells.org 19-smell academic catalog for tests in any language. Every finding maps to a named, citable smell from the research literature (Assertion Roulette, Duplicate Assert, Mystery Guest, Eager Test, Sensitive Equality, Conditional Test Logic, Sleepy Test, Magic Number Test, etc.) with research-backed severity. Polyglot: .NET (MSTest/xUnit/NUnit/TUnit), Python (pytest/unittest), TS/JS (Jest/Vitest/Mocha/node:test), Java (JUnit/TestNG), Go, Ruby (RSpec/Minitest), Rust, Swift, Kotlin (JUnit/Kotest), PowerShell (Pester), C++ (GoogleTest/Catch2).

Tasks

Audit test code across supported languages and frameworks for the testsmells.org 19-smell academic catalog, mapping findings to named, citable smells with severity rankings
Call the test-analysis-extensions skill to load and read the matching language extension file (e.g., extensions/dotnet.md, extensions/python.md) containing framework-specific test markers, sleep APIs, and skip annotations

Inputs

Test code (required: one or more test files or a test project directory to analyze)
Production code (optional: the code under test, for context on whether patterns are justified)

Outputs

Severity-ranked report with specific locations and actionable fixes

Limitations and checks

Do not use for general or pragmatic audits (use test-anti-patterns instead)
Do not use for writing new tests (use code-testing-agent or writing-mstest-tests for MSTest)
Do not use for running tests (use run-tests)
Do not use for framework migration
Verify that the target language and test framework are supported (e.g., .NET MSTest/xUnit/NUnit/TUnit, Python pytest/unittest, TS/JS Jest/Vitest/Mocha/node:test, Java JUnit/TestNG, Go, Ruby RSpec/Minitest, Rust, Swift, Kotlin JUnit/Kotest, PowerShell Pester, C++ GoogleTest/Catch2)
Ensure this skill is only invoked when explicitly asked for the testsmells.org 19-smell academic catalog or citable smell names from the literature
Confirm the test-analysis-extensions skill was called and the matching extension file was loaded to map framework-specific markers before scanning for smells
