SSDT Unit Test - How to mock GETDATE()?

Question

Some of our procedures/triggers returns values basing on current date, i.e.: GETDATE(), GETUTCDATE()
In such case a unit test will produce different result every time it is executed.
I found an article that one embeds GETDATE() into user defined function, and then at test runtime alters the function to return hardcoded date instead of current date.
http://pmichaels.net/2014/06/22/mock-current-date-and-time-in-sql-server/
What I don't like in such approach is that I will be forced to use custom user functions to get current date, change a lot of existing stored procedures and finally it can have negative impact on performance.
Is there a good method to handle such cases?

Hi, are you trying to just capture the day, month and year; something like '24-Apr-2015'?  If so try this code: -
Declare
@DateStr nvarchar(11)
Declare
@MonthNum int
Declare
@TempStr nvarchar(2)
Set
@Tempstr =(Select
Cast
(DatePart(dd,GetDate())
As
VarChar(2)))
IF
len(@Tempstr)=1
BEGIN
Set @Tempstr
=(Select
'0'+@Tempstr)
END
Set
@DateStr=(Select
(@TempStr+'-'))
Set
@MonthNum=(Select
DatePart(mm,GetDate()))
If
@MonthNum=1
Begin
Set @DateStr=(Select
(@DateStr+'Jan-'))
End
If
@MonthNum=2
Begin
Set @DateStr=(Select
(@DateStr+'Feb-'))
End
If
@MonthNum=3
Begin
Set @DateStr=(Select
(@DateStr+'Mar-'))
End
If
@MonthNum=4
Begin
Set @DateStr=(Select
(@DateStr+'Apr-'))
End
--Repeat above for all months
Set
@DateStr=(Select
(@DateStr+Cast
(DatePart(yyyy,GetDate())
As
VarChar(4))))
Print
@DateStr
