C# 使用Bogus创建模拟数据

很多时候测试方法的时候需要创建一些测试数据,平时我都是自己手写的,

今天发现了一个可以创建模拟数据的轮子Bogus,下面看看怎么使用的

首先引用Nuget包 

github : bchavez/Bogus: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js. (github.com)

测试代码在这里,更多用法可以看Git的案例

using Bogus.DataSets;

using System.Text;

        Male,

        Female

    {
        public int Id { get; set; }

        public string Name { get; set; }

        public int Age { get; set; }

        public Gender Gender { get; set; }

        public Sect Sect { get; set; }

        public override string ToString()
        {
            return $"{Id}  {Name}  {Age}  {Gender}  {Sect.Name}";
        }
    }

    public class Sect : IEquatable<Sect>
    {
        public string Address { get; set; }

        public string Name { get; set; }

        public DateTime Create { get; set; }

        public string Skill { get; set; }

        public bool Equals(Sect other)
        {
            return other.Name == Name;
        }

        public override string ToString()
        {
            return $"{Name}  {Address}  {Skill}  {Create.ToString("yyyy:MM")}";
        }

        public override bool Equals(object obj)
        {
            if (obj is Sect sect)
            {
                return sect.Equals(this);

                .RuleFor(o => o.Name, (f, o) => f.Name.FirstName())//使用Bogus自带的名称
                .RuleFor(o => o.Gender, f => f.PickRandom<Gender>())//从枚举中随机选择
                .RuleFor(o => o.Age, f => f.Random.Number(18, 54))//设定年龄
