Summary

Generates NUnit 3 tests in C#. Covers Assert.That constraint model, parameterized tests, setup/teardown, and Moq mocking. Use when user mentions "NUnit", "[TestFixture]", "[Test]", "Assert.That", "C# unit test". Triggers on: "NUnit", "[Test]", "Assert.That", "C# test", "NUnit3".

1	# NUnit 3 Testing Skill
2
3	## Core Patterns
4
5	### Basic Test
6
7	```csharp
8	using NUnit.Framework;
9
10	[TestFixture]
11	public class CalculatorTests
12	{
13	private Calculator _calculator;
14
15	[SetUp]
16	public void SetUp() => _calculator = new Calculator();
17
18	[Test]
19	public void Add_TwoPositiveNumbers_ReturnsSum()
20	{
21	Assert.That(_calculator.Add(2, 3), Is.EqualTo(5));
22	}
23
24	[Test]
25	public void Divide_ByZero_ThrowsException()
26	{
27	Assert.Throws<DivideByZeroException>(() => _calculator.Divide(10, 0));
28	}
29
30	[TearDown]
31	public void TearDown() { /* cleanup */ }
32	}
33	```
34
35	### Constraint Model (Assert.That)
36
37	```csharp
38	Assert.That(actual, Is.EqualTo(expected));
39	Assert.That(actual, Is.Not.EqualTo(unexpected));
40	Assert.That(value, Is.GreaterThan(5));
41	Assert.That(value, Is.InRange(1, 10));
42	Assert.That(str, Does.Contain("hello"));
43	Assert.That(str, Does.StartWith("He").IgnoreCase);
44	Assert.That(collection, Has.Count.EqualTo(3));
45	Assert.That(collection, Has.Member("item"));
46	Assert.That(collection, Is.All.GreaterThan(0));
47	Assert.That(obj, Is.Null);
48	Assert.That(obj, Is.Not.Null);
49	Assert.That(obj, Is.InstanceOf<MyClass>());
50	Assert.That(actual, Is.EqualTo(3.14).Within(0.01));
51	Assert.That(() => Method(), Throws.TypeOf<ArgumentException>()
52	.With.Message.Contains("invalid"));
53	```
54
55	### Parameterized Tests
56
57	```csharp
58	[TestCase(2, 3, 5)]
59	[TestCase(-1, 1, 0)]
60	[TestCase(0, 0, 0)]
61	public void Add_ReturnsCorrectSum(int a, int b, int expected)
62	{
63	Assert.That(_calculator.Add(a, b), Is.EqualTo(expected));
64	}
65
66	[TestCaseSource(nameof(DivisionCases))]
67	public void Divide_ReturnsCorrectQuotient(int a, int b, double expected)
68	{
69	Assert.That(_calculator.Divide(a, b), Is.EqualTo(expected).Within(0.01));
70	}
71
72	private static IEnumerable<TestCaseData> DivisionCases()
73	{
74	yield return new TestCaseData(10, 2, 5.0).SetName("10/2=5");
75	yield return new TestCaseData(7, 3, 2.33).SetName("7/3=2.33");
76	}
77	```
78
79	### Mocking with Moq
80
81	```csharp
82	using Moq;
83
84	[TestFixture]
85	public class UserServiceTests
86	{
87	private Mock<IUserRepository> _mockRepo;
88	private Mock<IEmailService> _mockEmail;
89	private UserService _service;
90
91	[SetUp]
92	public void SetUp()
93	{
94	_mockRepo = new Mock<IUserRepository>();
95	_mockEmail = new Mock<IEmailService>();
96	_service = new UserService(_mockRepo.Object, _mockEmail.Object);
97	}
98
99	[Test]
100	public void CreateUser_SavesAndSendsEmail()
101	{
102	_mockRepo.Setup(r => r.Save(It.IsAny<User>())).Returns(new User { Id = 1 });
103
104	var result = _service.CreateUser("alice@test.com", "Alice");
105
106	Assert.That(result.Id, Is.EqualTo(1));
107	_mockRepo.Verify(r => r.Save(It.IsAny<User>()), Times.Once);
108	_mockEmail.Verify(e => e.SendWelcome("alice@test.com"), Times.Once);
109	}
110	}
111	```
112
113	### Lifecycle
114
115	```
116	[OneTimeSetUp] → Before all tests in fixture
117	[SetUp] → Before each test
118	[Test] → Test method
119	[TearDown] → After each test
120	[OneTimeTearDown] → After all tests in fixture
121	```
122
123	### Categories and Attributes
124
125	```csharp
126	[Test, Category("Smoke")]
127	public void QuickTest() { }
128
129	[Test, Ignore("Bug #123")]
130	public void SkippedTest() { }
131
132	[Test, Timeout(5000)]
133	public void TimeLimitedTest() { }
134
135	[Test, Retry(3)]
136	public void FlakyTest() { }
137	```
138
139	### Anti-Patterns
140
141	\| Bad \| Good \| Why \|
142	\|-----\|------\|-----\|
143	\| `Assert.AreEqual(a, b)` (classic) \| `Assert.That(a, Is.EqualTo(b))` \| Constraint model is richer \|
144	\| No `[SetUp]` \| Proper lifecycle \| Resource management \|
145	\| Testing private methods \| Test public API \| Encapsulation \|
146	\| No categories \| `[Category("Smoke")]` \| Run subsets \|
147
148	## Setup: `dotnet add package NUnit NUnit3TestAdapter Microsoft.NET.Test.Sdk`
149	## Run: `dotnet test` or `dotnet test --filter TestCategory=Smoke`
150
151	## Deep Patterns
152
153	For advanced patterns, debugging guides, CI/CD integration, and best practices,
154	see `reference/playbook.md`.
