Moq设置返回一些硬编码的POCO

Question

我正在尝试使用此链接来获取moq中的一些对象以传递给我的服务。 http://allen-conway-dotnet.blogspot.com/2014/01/creating-unit-test-using-moq-to-stub.html

我在返回（）函数上遇到错误，说没有满足这个的重载函数。 全部，返回一个IQueryable对象。

Mock<IGroupsRepository> groupRepo;

groupRepo.Setup(m => m.All).Returns(new List<GROUPS>()
                {
                    new GROUPS { ID = 0, GROUP_NAME = "TEST1", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test1" },
                    new GROUPS { ID = 1, GROUP_NAME = "TEST2", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test2" }
                });

Answer 1

全部，返回一个IQueryable对象。

List<GROUPS>没有实现IQueryable<T> ，因此All永远不会返回这样的列表。

您可以在列表上调用AsQueryable来获取列表的IQueryable<T>表示。

var queryable = new List<GROUPS>()
                {
                    new GROUPS { ID = 0, GROUP_NAME = "TEST1", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test1" },
                    new GROUPS { ID = 1, GROUP_NAME = "TEST2", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test2" }
                }.AsQueryable();


groupRepo.Setup(m => m.All).Returns(queryable);

Answer 2

new List<GROUPS>()
                {
                    new GROUPS { ID = 0, GROUP_NAME = "TEST1", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test1" },
                    new GROUPS { ID = 1, GROUP_NAME = "TEST2", CREATED_DATE = DateTime.Now, CREATED_BY = "Joe Blow", DESCRIPTION = "Test2" }
                }
        .AsQueryable()

AsQueryable()应该使它与IQueryable返回类型兼容
