testland/xunit-tests

Configures and runs xUnit.net (xUnit v2 + v3) - current de facto .NET test framework with `[Fact]` for single tests + `[Theory]` + `[InlineData]`/`[ClassData]`/`[MemberData]` for parametrized; collection fixtures (`[Collection]`) + class fixtures (`IClassFixture`) for shared setup; output via `ITestOutputHelper`; parallel test config via assembly attribute. Use when working with .NET (C# / F# / VB.NET) on the modern test stack.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable skill body with a clear step sequence, a genuine verify→fix→re-run checkpoint, and proper offloading of detail to a single reference file. The only weakness is time-sensitive version/license information embedded inline rather than isolated in a deprecated/old-patterns section.

Suggestions

Move version-sensitive facts (e.g. 'v3 released 2024; v2 still widely used', the FluentAssertions 2024 license change and 'v6 is the last fully-free version') into a dedicated 'Versions / deprecations' or 'Old patterns' section so the main steps stay evergreen.

Add a brief validation checkpoint after Step 1 (install) mirroring Step 2's verify step — e.g. confirm `dotnet test` discovers 0 tests due to missing packages before writing the first test.

Consider tightening the Overview paragraph ('xUnit.net is the current .NET test standard …') since Claude already knows xUnit's role; keep only the v2/v3 coexistence fact that affects action.

DimensionReasoningScore

Conciseness

The body is largely lean and code-heavy, but time-sensitive version/license statements ('v3 released 2024; v2 still widely used' and 'FluentAssertions changed license in 2024 … v6 is the last fully-free version') appear inline rather than in a deprecated/old-patterns section, which the rubric penalizes.

2 / 3

Actionability

Every step ships executable, copy-paste-ready code and concrete commands (`dotnet new xunit`, `dotnet add package …`, `dotnet test --filter …`), matching the fully-executable anchor.

3 / 3

Workflow Clarity

Steps 1–7 are clearly sequenced, and Step 2 includes an explicit validation checkpoint with a feedback loop ('Verify … if it exits non-zero or discovers 0 tests, confirm the class is public … then re-run'), plus a Worked example tying the steps together.

3 / 3

Progressive Disclosure

The body is an overview that offloads fixtures and parallelism to a real one-level-deep `references/fixtures-and-parallelism.md`, clearly signaled and referenced multiple times, with content appropriately split.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A high-quality description: third-person voice, dense with concrete xUnit constructs, and pairing a clear capability list with an explicit 'Use when' trigger. It is distinctive and unlikely to conflict with sibling test skills.

DimensionReasoningScore

Specificity

Enumerates many concrete actions and constructs (`[Fact]`, `[Theory]` with `[InlineData]`/`[ClassData]`/`[MemberData]`, `[Collection]`/`IClassFixture` fixtures, `ITestOutputHelper`, assembly parallel config), matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Clearly states what it does (configures and runs xUnit v2/v3 with the listed features) and gives an explicit 'Use when working with .NET (C# / F# / VB.NET) on the modern test stack' trigger, satisfying both what and when.

3 / 3

Trigger Term Quality

Uses natural terms a user would say — 'xUnit', 'xUnit.net', '.NET', 'C# / F# / VB.NET', '[Fact]', '[Theory]', 'parametrized' — giving good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Scoped tightly to xUnit.net on the .NET stack with xUnit-specific attribute triggers, making it unlikely to fire for nunit/mstest or non-.NET skills.
