Testing & QA

dotnet Skill

Analyzes production code to find gaps in existing tests by reasoning about hypothetical mutations and checking whether tests would catch them.

dotnet Bundle

Generates and writes unit tests for any programming language using a multi-agent pipeline that researches, plans, and implements tests with build and verification steps.

dotnet Skill

Detects the test platform (VSTest vs Microsoft.Testing.Platform) and test framework (MSTest, xUnit, NUnit, TUnit) from .NET project files.

dotnet Skill

Audits test files for anti-patterns and quality issues, producing a severity-ranked report across multiple languages and frameworks.

dotnet Bundle

Audits test code in any language using the academic testsmells.org 19-smell catalog, producing a severity-ranked report with specific locations and actionable fixes.

dotnet Skill

Write, create, modernize, or fix comprehensive MSTest unit tests with MSTest 3.x/4.x APIs, covering assertions, data-driven tests, lifecycle, and async patterns.

dotnet Bundle

Parse source files to find which ones have no test file referencing their declared types, producing a prioritized worklist of untested files.

dotnet Bundle

Provides file paths to language-specific extension files for the code-testing pipeline, enabling discovery of guidance for .NET, Python, TypeScript, and other languages.

dotnet Bundle

Provides file paths to language-specific reference files for polyglot test analysis skills, enabling framework-aware detection of test markers, assertions, and patterns across .NET, Python, TypeScript, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, and C++.

dotnet Skill

Generate wrapper interfaces, default implementations, and DI registration code to make hard-to-test static dependencies in C# testable, using built-in abstractions like TimeProvider or custom wrappers.

dotnet Skill

Validates custom dotnet new templates for correctness before publishing, catching missing fields, parameter bugs, shortName conflicts, constraint issues, and common authoring mistakes.

dotnet Skill

Audits .NET test mock usage by tracing each mock setup through the production code's execution path to find dead, unreachable, redundant, or replaceable mocks.

dotnet Skill

Migrates .NET test projects from VSTest to Microsoft.Testing.Platform (MTP), updating project files, CLI arguments, and CI/CD pipelines for MSTest, NUnit, and xUnit.net.

dotnet Skill

Analyzes .NET test suites for duplicated boilerplate, copy-paste tests, and structural maintainability issues, producing a report with concrete before/after refactoring suggestions.

dotnet Skill

Fix build errors and breaking changes when upgrading MSTest from v3 to v4, or plan a complete migration.

dotnet Bundle

Migrate .NET test projects from xUnit.net (v2 or v3) to MSTest v4, converting attributes, assertions, fixtures, and project configuration.

dotnet Skill

Migrate test projects from MSTest v1 (assembly references) or v2 (NuGet 1.x-2.x) to MSTest v3, handling breaking changes like assertion overloads, DataRow constructors, .testsettings replacement, and target framework updates.

dotnet Skill

Migrates .NET test projects from xUnit.net v2 to xUnit.net v3, updating package references, project files, and code to compile and pass tests.

expo Bundle

Evaluates Expo skills end-to-end: trigger accuracy, generated code quality, and runtime screenshots on iOS simulator and Android emulator via Expo Go.

adobe Bundle

Generate and run Jest tests for Adobe App Builder actions and React Spectrum UI components, including unit, integration, contract, and component tests with mock helpers for Adobe SDKs.

adobe Bundle

Guide for testing code changes in AEM Edge Delivery projects including blocks, scripts, and styles. Use this skill after making code changes and before opening a pull request to validate functionality. Covers unit testing, browser testing with Playwright, and linting.

angular Bundle

Generates Angular code and provides architectural guidance for projects, components, services, reactivity, forms, dependency injection, routing, SSR, accessibility, animations, styling, testing, and CLI tooling.

github Bundle

Upgrades PowerShell Pester test suites across major versions (v3→v4, v4→v5, v5→v6) with structured workflows, reference guides, and safety rules.

github Bundle

Runs a complete quality engineering audit on any codebase, deriving behavioral requirements, generating spec-traced tests, performing multi-pass code review, and producing a consolidated bug report with verified patches.

github Skill

Enforce code quality with Ruff in a controlled, iterative workflow: run checks with optional scope and rule overrides, apply safe and unsafe autofixes, review diffs, and resolve remaining findings.

github Bundle

Provides expert guidance for testing Spring Boot 4 applications with modern patterns, test slices, and best practices.

github Bundle
