dotnet-test-frameworksReference data for .NET test framework detection patterns, assertion APIs, skip annotations, setup/teardown methods, and common test smell indicators across MSTest, xUnit, NUnit, and TUnit.
Dotnet Test Frameworks is an agent skill from runceel/ReactiveProperty. Reference data for .NET test framework detection patterns, assertion APIs, skip annotations, setup/teardown methods, and common test smell indicators across MSTest, xUnit, NUnit, and TUnit. DO NOT USE directly — loaded by test analysis skills (test-anti-patterns, exp-test-smell-detection, exp-assertion-quality, exp-test-maintainability, exp-test-tagging) when they need framework-specific lookup tables.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Unit testing. It works with .NET. The repository describes itself as: ReactiveProperty provides MVVM and asynchronous support features under Reactive Extensions. Target frameworks are .NET 6+, .NET Framework 4.7.2 and .NET Standard 2.0. The licence is MIT.
Read from SKILL.md and the folder at commit e7e6474. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Dotnet Test Frameworks loads about 1.4k tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 293 words of instructions outside code blocks.
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.
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.

.claude/skills/dotnet-test-frameworks/SKILL.md (or your agent's skills folder).Language-specific detection patterns for .NET test frameworks (MSTest, xUnit, NUnit, TUnit).
| Framework | Test class markers | Test method markers |
|---|---|---|
| MSTest | [TestClass] | [TestMethod], [DataTestMethod] |
| xUnit | (none — convention-based) | [Fact], [Theory] |
| NUnit | [TestFixture] | [Test], [TestCase], [TestCaseSource] |
| TUnit | [ClassDataSource] | [Test] |
| Category | MSTest | xUnit | NUnit |
|---|---|---|---|
| Equality | Assert.AreEqual | Assert.Equal | Assert.That(x, Is.EqualTo(y)) |
| Boolean | Assert.IsTrue / Assert.IsFalse | Assert.True / Assert.False | Assert.That(x, Is.True) |
| Null | Assert.IsNull / Assert.IsNotNull | Assert.Null / Assert.NotNull | Assert.That(x, Is.Null) |
| Exception | Assert.Throws<T>() / Assert.ThrowsExactly<T>() | Assert.Throws<T>() | Assert.That(() => ..., Throws.TypeOf<T>()) |
| Collection | CollectionAssert.Contains | Assert.Contains | Assert.That(col, Has.Member(x)) |
| String | StringAssert.Contains | Assert.Contains(str, sub) | Assert.That(str, Does.Contain(sub)) |
| Type | Assert.IsInstanceOfType | Assert.IsAssignableFrom | Assert.That(x, Is.InstanceOf<T>()) |
| Inconclusive | Assert.Inconclusive() | skip via [Fact(Skip)] | Assert.Inconclusive() |
| Fail | Assert.Fail() | Assert.Fail() (.NET 10+) | Assert.Fail() |
Third-party assertion libraries: Should* (Shouldly), .Should() (FluentAssertions / AwesomeAssertions), Verify() (Verify).
| Pattern | Example |
|---|---|
| Thread sleep | Thread.Sleep(2000) |
| Task delay | await Task.Delay(1000) |
| SpinWait | SpinWait.SpinUntil(() => condition, timeout) |
| Framework | Annotation | With reason |
|---|---|---|
| MSTest | [Ignore] | [Ignore("reason")] |
| xUnit | [Fact(Skip = "reason")] | (reason is required) |
| NUnit | [Ignore("reason")] | (reason is required) |
| TUnit | [Skip("reason")] | (reason is required) |
| Conditional | #if false / #if NEVER | (no reason possible) |
When a test uses try/catch to verify exceptions, suggest the framework-native alternative:
MSTest:
// Instead of try/catch (matches exact type):
var ex = Assert.ThrowsExactly<InvalidOperationException>(
() => processor.ProcessOrder(emptyOrder));
Assert.AreEqual("Order must contain at least one item", ex.Message);
// Or (also matches derived types):
var ex = Assert.Throws<InvalidOperationException>(
() => processor.ProcessOrder(emptyOrder));
Assert.AreEqual("Order must contain at least one item", ex.Message);xUnit:
var ex = Assert.Throws<InvalidOperationException>(
() => processor.ProcessOrder(emptyOrder));
Assert.Equal("Order must contain at least one item", ex.Message);NUnit:
var ex = Assert.Throws<InvalidOperationException>(
() => processor.ProcessOrder(emptyOrder));
Assert.That(ex.Message, Is.EqualTo("Order must contain at least one item"));| Smell indicator | What to look for |
|---|---|
| File system | File.ReadAllText, File.Exists, File.WriteAllBytes, Directory.GetFiles, Path.Combine with hard-coded paths |
| Database | SqlConnection, DbContext (without in-memory provider), SqlCommand |
| Network | HttpClient without HttpMessageHandler override, WebRequest, TcpClient |
| Environment | Environment.GetEnvironmentVariable, Environment.CurrentDirectory |
| Acceptable | MemoryStream, StringReader, InMemory database providers, custom DelegatingHandler |
Recognize these as integration tests (adjust smell severity accordingly):
Integration, E2E, EndToEnd, or Acceptance[TestCategory("Integration")] (MSTest)[Trait("Category", "Integration")] (xUnit)[Category("Integration")] (NUnit).IntegrationTests or .E2ETests| Framework | Setup | Teardown |
|---|---|---|
| MSTest | [TestInitialize] or constructor | [TestCleanup] or IDisposable.Dispose / IAsyncDisposable.DisposeAsync |
| xUnit | constructor | IDisposable.Dispose / IAsyncDisposable.DisposeAsync |
| NUnit | [SetUp] | [TearDown] |
| MSTest (class) | [ClassInitialize] | [ClassCleanup] |
| NUnit (class) | [OneTimeSetUp] | [OneTimeTearDown] |
| xUnit (class) | IClassFixture<T> | fixture's Dispose |

Reference data for .NET test framework detection patterns, assertion APIs, skip annotations, setup/teardown methods, and common test smell indicators across MSTest, xUnit, NUnit, and TUnit. Dotnet Test Frameworks is an agent skill from runceel/ReactiveProperty.NET test framework detection patterns, assertion APIs, skip annotations, setup/teardown methods, and common test smell indicators across MSTest, xUnit, NUnit, and TUnit.
Dotnet Test Frameworks fits situations like: tasks that involve Unit testing.
Run `npx skills add runceel/ReactiveProperty --skill dotnet-test-frameworks -a claude-code`. Or copy the skill folder (.agents/skills/dotnet-test-frameworks in runceel/ReactiveProperty) into .claude/skills/dotnet-test-frameworks in your project. Claude Code loads it when a task matches its description.
Run `npx skills add runceel/ReactiveProperty --skill dotnet-test-frameworks -a codex`. Or copy the skill folder (.agents/skills/dotnet-test-frameworks in runceel/ReactiveProperty) into .agents/skills/dotnet-test-frameworks in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add runceel/ReactiveProperty --skill dotnet-test-frameworks -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/dotnet-test-frameworks, .gemini/skills/dotnet-test-frameworks, .github/skills/dotnet-test-frameworks and .opencode/skills/dotnet-test-frameworks in your project.
SKILL.md names no scripts, command-line tools or credentials: Dotnet Test Frameworks is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Dotnet Test Frameworks is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
