c# - 在c#中运行单元测试时如何处理InvalidoperationException

Question

我使用 MOQ 编写了单元测试。设置模拟时，我试图在 Linq 查询中创建类的对象。之后，我尝试运行单元测试，但收到以下错误消息。

"When called from 'VisitMemberInit', rewriting a node of type 'System.Linq.Expressions.NewExpression' must return a non-null value of the same type. Alternatively, override 'VisitMemberInit' and change it to not visit children of this type."

我写了如下代码-

    _mockLdapAuthenticatorService.Setup(x => x.Authenticate(
                        new LoginRequest { 
                                Username = It.IsAny<string>(), 
                                Password = It.IsAny<string>() })).
                                Returns(new     AuthenticationResult { Success = true });

更新设置。以下可能是您想要实现的目标。

_mockLdapAuthenticatorService
   .Setup(x => x.Authenticate(It.IsAny<LoginRequest>()))
   .Returns(new AuthenticationResult { Success = true });
