Question

我正在尝试使用Moq模拟以下方法：

public interface IGenericRepository<TEntity> where TEntity : class
{
    ...

    IEnumerable<TEntity> Get(Expression<Func<TEntity, bool>> filter = null,
        Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "");

}

它以这种方式初始化：

_invoiceRepository = new SqlGenericRepository<InvoiceEntity>(Context);

无论参数如何，该方法都应该始终返回一个列表。

我试过

_invoiceRepositoryMock.Setup(m => m.Get(It.IsAny<>()).Returns(...)

和

_invoiceRepositoryMock.Setup(m => m.Get(It.IsAny<Expression<Func<InvoiceEntity, bool>>>())).Returns(...)

但两者都不起作用。

Answer 1

如果你的方法是：

IEnumerable<TEntity> Get(
    Expression<Func<TEntity, bool>> filter = null,
    Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null,    
    string includeProperties = "");

你的模拟必须是这样的：

_invoiceRepositoryMock.Setup(m => m.Get(
    It.IsAny<Expression<Func<InvoiceEntity, bool>>>(),
    It.IsAny<Func<IQueryable<InvoiceEntity>, IOrderedQueryable<InvoiceEntity>>>(),
    It.IsAny<string>())).Returns(...)

Answer 2

假设

var _invoiceRepositoryMock = new Mock<InvoiceEntity>();

然后设置

_invoiceRepositoryMock
    .Setup(m => m.Get(
        It.IsAny<Expression<Func<InvoiceEntity, bool>>>(),
        It.IsAny<Func<IQueryable<InvoiceEntity>, IOrderedQueryable<InvoiceEntity>>>(),
        It.IsAny<string>()))
    .Returns(...);

或更具体的

_invoiceRepositoryMock
    .Setup(m => m.Get(It.IsAny<Expression<Func<InvoiceEntity, bool>>>(), null, string.Empty))
    .Returns(...);

Answer 3

你可以尝试这样尝试，因为该方法有4个参数，尝试在模拟中给出4个参数_invoiceRepositoryMock.Setup(m => m.Get(It.IsAny<>(),It.IsAny<>(),It.IsAny<>(),It.IsAny<>()).Returns(...

通用存储库的模拟方法
