tsqlt和动态SQL

Question

我想测试它使用动态SQL这样一个存储过程：

DECLARE @Sql NVARCHAR(MAX) 

-- create @Sql 

EXEC sp_executesql @Sql 
,N'@NumberOfRollingMonths INT, @FromDate DATETIME, @ToDate DATETIME' 
,@NumberOfRollingMonths = @NumberOfRollingMonths 
,@FromDate = @FromDate 
,@ToDate = @ToDate 

无论我做什么，我没有得到测试通过。我正在使用

EXEC tSQLt.FakeTable 

虚假底层数据库的数据。 tsqlt不适用于动态sql是否是已知的事实？

PS：

更多的代码：

IF OBJECT_ID('TestDetails', 'U') IS NOT NULL 
    DROP TABLE TestDetails 

CREATE TABLE TestDetails

    Year INT, 
    Period INT,

    SELECT 2004, 1, 10000 UNION ALL 
    SELECT 2004, 2, 100 

IF OBJECT_ID('TestMonthsAndYears', 'U') IS NOT NULL 
    DROP TABLE TestMonthsAndYears 

CREATE TABLE TestMonthsAndYears

正如其他人评论说，动态SQL确实与tSQLt工作。如果没有您遇到问题的代码/测试，很难确定问题可能出在哪里。

为了帮助你一起，并帮助恢复tSQLt你的信心，这是一个使用动态SQL一个SP，并调用它的测试，而假表的例子，单元测试的过程：

USE tSQLt_Example 
GO 
--Example table in which we will manipulate data 
CREATE TABLE dbo.DynamicDemo (a INT) 
GO 
INSERT dbo.DynamicDemo (a) VALUES (5) -- This value will be removed by FakeTable 
GO 
--Example proc which uses Dynamic SQL 
CREATE PROC dbo.DynamicAdd (@NoToAdd int) as 
DECLARE @s NVARCHAR(MAX) 
SET @s = 'update dbo.DynamicDemo set a=a+@NoToAdd' 
EXEC sp_executesql @s,N'@NoToAdd int',@NoToAdd = @NoToAdd 
GO 
--create tSQLt class 
exec tSQLt.NewTestClass @ClassName = N'DynamicTest' -- nvarchar(max) 
GO 
--Create test on proc which uses dynamic SQL 
CREATE PROC DynamicTest.[test dynamic sql] 
as 
--Assemble 
EXEC tSQLt.faketable 'dbo.DynamicDemo' 
SELECT TOP 0 * into DynamicTest.Expected FROM dbo.DynamicDemo 
INSERT dbo.DynamicDemo (a) VALUES (4) --Start position 
INSERT DynamicTest.Expected (a) VALUES (7) -- Expected end position 
--Act 
EXEC dbo.DynamicAdd 3 --call proc under test 
--Assert 
EXEC tSQLt.AssertEqualsTable @Actual='dbo.DynamicDemo', @Expected = 'DynamicTest.Expected' 
GO 
--Run Tests 
EXEC tSQLt.Run 'DynamicTest' 
GO 
--Clearup 
DROP TABLE dbo.dynamicDemo 
DROP PROC dbo.DynamicAdd 

这个简单的例子应该有助于让你放心，tSQLt本身能够使用动态SQL就好 - 也许还有另一个依赖性会导致你的问题？如果（如其他人所说的）你可以发布一个（可运行的）你的问题的例子，我们可以帮助你找出造成你这种痛苦的原因。
