Generate robust, zero-flakiness Playwright E2E tests following OpenMetadata patterns. Creates comprehensive test files with proper waits, API validation, multi-role permissions, and complete entity lifecycle management.
test-anti-patterns
by dotnet
Audit an existing test file or suite and produce a severity-ranked diagnostic report. ALWAYS USE for findings about tests that verify nothing, missing or tautological assertions, swallowed/broad exceptions, flaky or order-dependent tests, duplication, or magic values. Polyglot. DO NOT USE for direct edits: use writing-mstest-tests for supplied MSTest assertions, attributes, or lifecycle, and code-testing-agent for new tests. Do not use for running tests, migration, assertion metrics (assertion-quality), coverage/CRAP metrics, or the testsmells.org catalog (test-smell-detection).
test-gap-analysis
by dotnet
Find or close verified gaps in existing tests. USE FOR: "add missing edge cases", "would tests catch this bug?", weak tests, survived boundaries/guards/ errors, or pseudo-mutation analysis. Polyglot. DO NOT USE FOR: a new suite (code-testing-agent), smells/assertion audits, or an actual mutation tool.
grade-tests
by dotnet
Grades a specified set of test methods individually and produces a concise table mapping each test (fully-qualified name) to a letter grade (A–F), a score band, and a one-line note — designed to be posted as a PR comment. Use when the caller wants per-test feedback on a curated list of methods (for example, the new or modified tests in a pull request), not a suite-wide audit. Polyglot: .NET, Python, TS/JS, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, C++. Input is a list of test methods (or method bodies / file+line spans); output is a compact markdown table plus a short summary. DO NOT USE FOR: full suite audits (use test-quality-auditor agent or test-anti-patterns), writing new tests (use code-testing-generator agent or writing-mstest-tests), fixing failures, or measuring code coverage.
code-testing-extensions
by dotnet
Provides file paths to language-specific extension files for the code-testing pipeline. Call this skill to discover available extension guidance files (e.g., dotnet.md for .NET, cpp.md for C++). Do not use directly — invoked by code-testing agents and skills that need language-specific references.
migrate-vstest-to-mtp
by dotnet
Migrates .NET test projects from VSTest to Microsoft.Testing.Platform (MTP). Use when user asks to "migrate to MTP", "switch from VSTest", "enable Microsoft.Testing.Platform", "use MTP runner", set OutputType=Exe only for test projects in Directory.Build.props, or mentions EnableMSTestRunner, EnableNUnitRunner, or UseMicrosoftTestingPlatformRunner. USE FOR: MTP behavioral differences vs VSTest (exit code 8, zero tests discovered, --ignore-exit-code, TESTINGPLATFORM_EXITCODE_IGNORE); centralizing MTP properties and OutputType=Exe on test projects via MSBuildProjectName, not IsTestProject. Supports MSTest, NUnit, xUnit.net v2 (via YTest.MTP.XUnit2), and xUnit.net v3. Covers runner enablement, CLI argument and filter translation (--filter-class/--filter-trait/--filter-query), global.json config, CI/CD updates, and extension packages. DO NOT USE FOR: migrating between test frameworks (MSTest/xUnit/NUnit), xUnit.net v2 to v3 API migration, MSTest version upgrades, TFM upgrades, or UWP/WinUI test projects.
agentic-workflows
by dotnet
Route gh-aw workflow design/create/debug/upgrade requests to the right prompts.
test-smell-detection
by dotnet
Audits existing tests in any language using formal, research-backed test smell names and the testsmells.org 19-smell academic taxonomy. Use when the caller asks for an academic or citable test-smell review, named smell categories, or a formal severity-ranked smell assessment. Covers Assertion Roulette, Conditional Test Logic, Mystery Guest, Eager Test, Sleepy Test, Unknown Test, Sensitive Equality, and the rest of the catalog across .NET, Python, JavaScript/TypeScript, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, and C++. DO NOT USE FOR a quick pragmatic test review (use test-anti-patterns), writing or running tests, framework migration, coverage, or assertion-diversity metrics.
run-tests
by dotnet
Run or recommend the exact .NET test command. ALWAYS USE when asked to run, filter, or troubleshoot .NET tests or provide precise flags/argument order. Supports SDK-style dotnet test and classic non-SDK projects using MSBuild plus vstest.console/MSTest or repository scripts. USE FOR: all tests or subsets by class/category/trait; multi-TFM --framework; TRX reports; crash/hang dumps; VSTest vs Microsoft.Testing.Platform; bridged vs native MTP argument syntax; --filter, --filter-class, --filter-trait, --filter-query, and --treenode-filter. Detects MSTest/xUnit/NUnit/TUnit and packages.config/classic project constraints. DO NOT USE FOR: writing tests (use code-testing-agent), MTP hot-reload iteration, CI/CD configuration, or debugging test logic.
find-untested-sources
by dotnet
MANDATORY for static requests to find, identify, or list untested source files or modules, sources without tests, source-to-test pairing, test-gap worklists, or suggested test locations. Invoke even for a tiny package; do not substitute manual globbing. Uses Roslyn for C#/.NET and tree-sitter for Python, TS/JS, Go, Java, Rust, and Ruby. DO NOT USE FOR: line/branch coverage, CRAP risk, or grading existing tests.
maui-dependency-injection
by dotnet
Guidance for configuring dependency injection in .NET MAUI apps — service registration in MauiProgram.cs, lifetime selection (Singleton / Transient / Scoped), constructor injection, Shell navigation auto-resolution, platform-specific registrations, and testability patterns. USE FOR: "dependency injection", "DI setup", "AddSingleton", "AddTransient", "AddScoped", "service registration", "constructor injection", "IServiceProvider", "MauiProgram DI", "register services", "BindingContext injection". DO NOT USE FOR: data binding (use maui-data-binding), Shell route configuration (use maui-shell-navigation), unit-test mocking frameworks (use standard xUnit and NSubstitute patterns).
