csharp-mstest SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
csharp-mstest from github/awesome-copilot is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add github/awesome-copilot/csharp-mstest@git:20260224.caab1f6Pins git:20260224.caab1f6 in mdr.lock. Pin the fingerprint instead.

Get best practices for MSTest 3.x/4.x unit testing, including modern assertion APIs and data-driven tests.
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
# MSTest Best Practices (MSTest 3.x/4.x)
Your goal is to help me write effective unit tests with modern MSTest, using current APIs and best practices.
## Project Setup
- Use a separate test project with naming convention `[ProjectName].Tests`
- Reference MSTest 3.x+ NuGet packages (includes analyzers)
- Consider using MSTest.Sdk for simplified project setup
- Run tests with `dotnet test`
## Test Class Structure
- Use `[TestClass]` attribute for test classes
- **Seal test classes by default** for performance and design clarity
- Use `[TestMethod]` for test methods (prefer over `[DataTestMethod]`)
- Follow Arrange-Act-Assert (AAA) pattern
- Name tests using pattern `MethodName_Scenario_ExpectedBehavior`
```csharp
[TestClass]
public sealed class CalculatorTests
{
[TestMethod]
public void Add_TwoPositiveNumbers_ReturnsSum()
{
// Arrange
var calculator = new Calculator();
// Act
var result = calculator.Add(2, 3);
// Assert
Assert.AreEqual(5, result);
}
}
```
## Test Lifecycle
- **Prefer constructors over `[TestInitialize]`** - enables `readonly` fields and follows standard C# patterns

How to install
mdr add github/awesome-copilot/csharp-mstest@sha256:325e70e82f3edecbThe line at the top of this page pins the label git:20260224.caab1f6, 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.
