一、Unit Testing

• 适合单元测试的代码

1.1 创建X unit 测试项目

1. 创建项目目录

• 创建测试
  
• 目录
  

2. 管理包

1. 修改Packages.props
   
2. 修改项目本身的包，并且添加项目引用到api项目

<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的项目配置中添加，我们就可以引用internal 类型在Unitest里
   

1.2 创建CreateEntryDtoValidator测试

• 创建CreateEntryDtoValidatorTests用来测试
  

namespace DevHabit.UnitTests.Validators;
public class CreateEntryDtoValidatorTests
{private readonly CreateEntryDtoValidator _validator = new();[Fact] // 用来定义不带参数的独立测试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); //通过验证，错误列表为空}[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); //验证失败ValidationFailure validationFailure = Assert.Single(validationResult.Errors); //检查错误列表里应该有且只有一个错误Assert.Equal(nameof(CreateEntryDto.HabitId), validationFailure.PropertyName); //验证这个错误是针对 HabitId 字段的}
}

1.3 创建CreateEntryDtoValidator测试

• 为加密服务创建测试

public sealed class EncryptionServiceTests
{private
