一、Unit Testing

• 適合單元測試的代碼

1.1 創建X unit 測試項目

1. 創建項目目錄

• 創建測試
  
• 目錄
  

2. 管理包

1. 修改Packages.props
   
2. 修改項目本身的包，并且添加項目引用到api項目

<Project Sdk="Microsoft.NET.Sdk"><PropertyGroup><IsPackable>false</IsPackable></PropertyGroup><ItemGroup><PackageReference Include="coverlet.collector" /><PackageReference Include="Microsoft.NET.Test.Sdk" /><PackageReference Include="xunit" /><PackageReference Include="xunit.runner.visualstudio" /></ItemGroup><ItemGroup><ProjectReference Include="..\DevHabit\DevHabit.Api\DevHabit.Api.csproj" /></ItemGroup><ItemGroup><Using Include="Xunit" /></ItemGroup></Project>

3. 在api的項目配置中添加，我們就可以引用internal 類型在Unitest里
   

1.2 創建CreateEntryDtoValidator測試

• 創建CreateEntryDtoValidatorTests用來測試
  

namespace DevHabit.UnitTests.Validators;
public class CreateEntryDtoValidatorTests
{private readonly CreateEntryDtoValidator _validator = new();[Fact] // 用來定義不帶參數的獨立測試public async Task Validate_ShouldSucceed_WhenInputDtoIsValid(){// Arrangevar dto = new CreateEntryDto{HabitId = Habit.NewId(),Value = 1,Date = DateOnly.FromDateTime(DateTime.UtcNow)};// ActValidationResult validationResult = await _validator.ValidateAsync(dto);// AssertAssert.True(validationResult.IsValid);Assert.Empty(validationResult.Errors); //通過驗證，錯誤列表為空}[Fact]public async Task Validate_ShouldFail_WhenHabitIdIsEmpty(){// Arrangevar dto = new CreateEntryDto{HabitId = string.Empty,Value = 1,Date = DateOnly.FromDateTime(DateTime.UtcNow)};// ActValidationResult validationResult = await _validator.ValidateAsync(dto);// AssertAssert.False(validationResult.IsValid); //驗證失敗ValidationFailure validationFailure = Assert.Single(validationResult.Errors); //檢查錯誤列表里應該有且只有一個錯誤Assert.Equal(nameof(CreateEntryDto.HabitId), validationFailure.PropertyName); //驗證這個錯誤是針對 HabitId 字段的}
}

1.3 創建CreateEntryDtoValidator測試

• 為加密服務創建測試

public sealed class EncryptionServiceTests
{private
