C# and .NET testing patterns with xUnit, FluentAssertions, mocking, integration tests, and test organization best practices. Use when writing or reviewing xUnit tests, mocks, or integration tests in a C# / .NET project.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# C# Testing Patterns
Comprehensive testing patterns for .NET applications using xUnit, FluentAssertions, and modern testing practices.
## When to Activate
- Writing new tests for C# code
- Reviewing test quality and coverage
- Setting up test infrastructure for .NET projects
- Debugging flaky or slow tests
## Test Framework Stack
| Tool | Purpose |
|---|---|
| **xUnit** | Test framework (preferred for .NET) |
| **FluentAssertions** | Readable assertion syntax |
| **NSubstitute** or **Moq** | Mocking dependencies |
| **Testcontainers** | Real infrastructure in integration tests |
| **WebApplicationFactory** | ASP.NET Core integration tests |
| **Bogus** | Realistic test data generation |
## Unit Test Structure
### Arrange-Act-Assert
```csharp
public sealed class OrderServiceTests
{
private readonly IOrderRepository _repository = Substitute.For<IOrderRepository>();
private readonly ILogger<OrderService> _logger = Substitute.For<ILogger<OrderService>>();
private readonly OrderService _sut;
public OrderServiceTests()
{
_sut = new OrderService(_repository, _logger);
}

How to install
mdr add wankimmy/bossku-superpowers/csharp-testing@sha256:ee93aae975fa9d44The line at the top of this page pins the label git:20261012.feb2361, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
