Curated by Skill Harbor: a comprehensive testing skill for .NET built on the modern stack: xUnit as the framework, FluentAssertions for readable assertions, NSubstitute or Moq for mocking, Testcontainers for real infrastructure in integration tests, and WebApplicationFactory for ASP.NET Core. It covers the Arrange-Act-Assert structure, test organization, realistic data generation with Bogus, and the eternal enemies: flaky and slow tests. The examples are real test classes, so you see the substitute setup and assertion style instead of theory. By @affaan-m, listed here with credit to its creator. From the affaan-m/ECC repository (MIT). Honest caveats: pure guidance, nothing to install; assumes a .NET project with xUnit referenced; Testcontainers sections need Docker available. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseThe install prompt below already includes the vetting steps: your agent follows the community checklist before installing anything with executable code. Want more?
Use "C# Testing" with your Muse. Prerequisites: a .NET project with xUnit available (Docker needed for Testcontainers parts). Pure guidance skill, nothing to install. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/csharp-testing/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Review these xUnit tests against these patterns: Arrange-Act-Assert, assertion readability, mock usage." 3. For new tests, ask: "Write xUnit tests for this service with FluentAssertions and NSubstitute, following Arrange-Act-Assert." Tip: use Bogus for realistic test data; it beats hand-written fixtures. Safety: a skill is plain-text instructions; it runs nothing by itself. Never paste secrets into a chat, and review anything Muse proposes before it changes your code.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
