C# Unit Testing Guidelines (NUnit + NSubstitute) 1. Follow the **Arrange-Act-Assert (AAA)** pattern: - **Arrange**: Prepare inputs, dependencies and mocks. - **Act**: Execute the method under test. - **Assert**: Validate the expected results or interactions. 2. Use `[Test]` for individual test cases. Prefer `[TestCase(...)]` for parameterized scenarios: - `[Test]` – single specific scenario. - `[TestCase]` – when testing same logic with different inputs. 3. Naming convention: MethodName_Scenario_ExpectedOutcome Example: `CalculateTotal_WithValidInput_ReturnsCorrectSum` 4. Use **NSubstitute** to create fake dependencies: ```csharp var repository = Substitute.For<IRepository>(); repository.GetAll().Returns(new[] { ... });
