我正在尝试验证我测试的方法是否已使用特定表达式调用。我花了几个小时没有得到我想要的结果。
这是被测系统
public class sut
{
private IEntityUtil _ew;
public sut(IEntityUtil ew)
{
_ew = ew;
}
public void Search()
{
Guid id = Guid.Parse("CB594050-3845-4EAF-ABC5-34840063E94F");
var res = _ew.SelectSingle<Post>(w => w.Id == id, new PersonalSiteEntities());
}
}
这是依赖
public interface IEntityUtil
{
TEntity SelectSingle<TEntity>(Expression<Func<TEntity, bool>> predicate, System.Data.Objects.ObjectContext ctx)
where TEntity : EntityObject;
List<TEntity> SelectList<TEntity>(Expression<Func<TEntity, bool>> predicate, System.Data.Objects.ObjectContext ctx)
where TEntity : EntityObject;
bool Insert<TEntity>(TEntity entity, System.Data.Objects.ObjectContext ctx)
where TEntity : EntityObject;
}
这就是我试图测试它的方式
public class tst
{
[TestMethod]
public void tst1()
{
var cwMock = new Mock<ConsoleApplication1.IEntityUtil>();
Guid id = Guid.Parse("CB594050-3845-4EAF-ABC5-34840063E94F");
//cwMock.Setup(x => x.SelectSingle<ConsoleApplication1.Post>(w => w.Id == id, It.IsAny<System.Data.Objects.ObjectContext>())).Returns(new ConsoleApplication1.Post()).Verifiable();
//cwMock.Setup(x => x.SelectSingle(It.IsAny<Expression<Func<ConsoleApplication1.Post, bool>>>(), It.IsAny<System.Data.Objects.ObjectContext>())).Returns(new ConsoleApplication1.Post()).Verifiable();
Expression<Func<ConsoleApplication1.Post, bool>> func = (param) => param.Id == id;
cwMock.Setup(x => x.SelectSingle<ConsoleApplication1.Post>(func, It.IsAny<System.Data.Objects.ObjectContext>())).Returns(new ConsoleApplication1.Post());
var sut = new ConsoleApplication1.sut(cwMock.Object);
sut.Search();
//cwMock.VerifyAll();
cwMock.Verify(x => x.SelectSingle(func, It.IsAny<System.Data.Objects.ObjectContext>()));
}
}
请注意,第二个注释设置将使测试通过,但它不会让我验证是否已传入特定表达式。
提前致谢。
