c# - 模拟 IOptionsMonitor

Question

如何在构造函数中为需要 IOptionsMonitor 的类手动创建类实例？

我的类(class)

private readonly AuthenticationSettings _authenticationSettings;

public ActiveDirectoryLogic(IOptionsMonitor<AuthenticationSettings> authenticationSettings)
{            
   _authenticationSettings = authenticationSettings.CurrentValue;
}

我的测试

AuthenticationSettings au = new AuthenticationSettings(){ ... };
var someOptions = Options.Create(new AuthenticationSettings());
var optionMan = new OptionsMonitor(someOptions);  // dont work.           
ActiveDirectoryLogic _SUT = new ActiveDirectoryLogic(au);

我试图手动创建一个 IOptionsMonitor 对象，但不知道怎么做。

Answer 1

您正在调用 OptionsMonitor<TOptions> 的构造函数类错误。

在这种情况下，我只会 mock IOptionsMonitor<AuthenticationSettings>界面

例如使用 Moq

AuthenticationSettings au = new AuthenticationSettings() { ... };
var monitor = Mock.Of<IOptionsMonitor<AuthenticationSettings>>(_ => _.CurrentValue == au);
ActiveDirectoryLogic _SUT = new ActiveDirectoryLogic(monitor);
