What it does

Dotnet Testing is an agent skill from novotnyllc/dotnet-artisan. Defines .NET test strategy and implementation patterns across xUnit v3 (Facts, Theories, fixtures, IAsyncLifetime), integration testing (WebApplicationFactory, Testcontainers), Aspire testing (DistributedApplicationTestingBuilder), snapshot testing (Verify, scrubbing), Playwright E2E browser automation, BenchmarkDotNet microbenchmarks, code coverage (Coverlet), mutation testing (Stryker.NET), UI testing (page objects, selectors), and AOT WASM test compilation. Spans 13 topic areas. Do not use for production API…

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including reference files (for example `agents/openai.yaml`, `references/add-testing.md` and `references/aot-wasm.md`).

It sits in Testing & QA, covering Integration testing, Test coverage and Unit testing. It works with .NET, Playwright and WebAssembly. The repository describes itself as: Comprehensive .NET development skills for modern C and .NET. The licence is MIT.

When your agent uses it

  • Production API architecture
  • CI workflow authoring

Example prompts

  • “Use the dotnet-testing skill to define .NET test strategy and implementation patterns across xUnit v3 (Facts, Theories, fixtures, IAsyncLifetime)…”
  • “/dotnet-testing”

What it can do on your machine

Read from SKILL.md and the folder at commit 3db3ae6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dotnet Testing loads about 972 tokens when it runs, and up to ~44k if it reads all its reference files. Until then it costs about 143 tokens; SKILL.md has 333 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~143
When it runs · the whole SKILL.md, loaded when a task matches
~972
With references · SKILL.md plus every file in references/, read only if the agent opens them
~44k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Overview

Testing strategy, frameworks, and quality tooling for .NET applications. This consolidated skill spans 13 topic areas. Load the appropriate companion file from references/ based on the routing table below.

Baseline dependency: references/testing-strategy.md defines the unit vs integration vs E2E decision tree and test doubles selection that inform all testing decisions. Load it by default whenever a testing approach needs to be chosen.

Most-shared companion: references/xunit.md covers xUnit v3 framework features used by integration, snapshot, and UI testing companions.

Scope

  • Test strategy and architecture (unit, integration, E2E)
  • xUnit v3 test authoring
  • Integration testing (WebApplicationFactory, Testcontainers)
  • E2E browser testing (Playwright)
  • Snapshot testing (Verify)
  • Benchmarking (BenchmarkDotNet, CI gating)
  • Quality (coverage, mutation testing)
  • Cross-framework UI testing patterns
  • Test scaffolding

Out of scope

  • UI framework-specific testing (bUnit, Appium) -> dotnet-ui
  • CI/CD pipeline configuration -> dotnet-devops
  • Performance profiling -> dotnet-tooling
