C# 如何在abp框架中使用nSubstitute模拟依赖关系,
在Abp框架中,我试图为我的FamilyAppService类编写一个测试(见下文)。我需要在FamilyAppService的构造函数中模拟一个IAutho实例。我尝试模拟IAutho,然后将其添加到FamilyAppService的新实例中(而不是使用GetRequiredService()),但ObjectMapper出现了“System.ArgumentNullException”错误 家庭服务类C# 如何在abp框架中使用nSubstitute模拟依赖关系,,c#,testing,nsubstitute,abp,C#,Testing,Nsubstitute,Abp,在Abp框架中,我试图为我的FamilyAppService类编写一个测试(见下文)。我需要在FamilyAppService的构造函数中模拟一个IAutho实例。我尝试模拟IAutho,然后将其添加到FamilyAppService的新实例中(而不是使用GetRequiredService()),但ObjectMapper出现了“System.ArgumentNullException”错误 家庭服务类 public class FamilyAppService : KmAppSer

Autho类。
我需要使用nSubstitute用模拟类替换IAutho依赖
public class Autho : IAutho, ITransientDependency {
public Autho( ) {
}
public virtual async Task<User> FindUserIdByEmail(string input) {
// Don’t want this code touched in test
// Code ...
}
}
公共类Autho:IAutho,ITransientDependency{
公共作者(){
}
公共虚拟异步任务FindUserIdByEmail(字符串输入){
//不希望在测试中触碰此代码
//代码。。。
}
}
我目前的测试
[Fact]
public async Task ShouldSendEmail() {
var autho = Substitute.For<IAutho>();
autho.FindUserIdByEmail(Arg.Any<string>()).Returns((User)null);
var familyAppService = new FamilyAppService(autho);
// var familyAppService = GetRequiredService<IFamilyAppService>();
// setup input code here..
// get ObjectMapper error here
await familyAppService.SendRequest(input);
// Assert
}
[事实]
公共异步任务应发送电子邮件(){
var autho=替换.For();
autho.FindUserIdByEmail(Arg.Any())。返回((用户)null);
var familyAppService=新的familyAppService(autho);
//var familyAppService=GetRequiredService();
//此处设置输入代码。。
//在此处获取ObjectMapper错误
等待familyAppService.SendRequest(输入);
//断言
}
github abp回购协议的一位成员给了我正确的答案。您需要重写测试类上的AfterAddApplication方法,并将替换项/mock添加到services.AddSingletone
例如
protected override void AfterAddApplication(IServiceCollection services) {
var autho = Substitute.For<IAutho>();
autho.FindUserIdByEmail(Arg.Any<string>()).Returns((User)null);
services.AddSingleton(autho);
}
受保护的override void AfterAddApplication(IServiceCollection服务){
var autho=替换.For();
autho.FindUserIdByEmail(Arg.Any())。返回((用户)null);
服务。AddSingleton(autho);
}
