How to test a trigger?

Postby AdamY » Thu Mar 28, 2013 8:19 pm

TableA has Trigger1 that inserts data into TableB. I'd like to test that the trigger works correctly. Can I do that with SQL Test? I haven't been able to find a way yet. Does FakeTable handle triggers?

Hi AdamY,

Thanks for your post. It looks like something simliar has been covered in stackoverflow: ... e-triggers

It looks like there is a workaround solution to make this happen.

kenbroz - the answer Steve (stanori) posted has a link to a work-around solution. tSQLt is working on a permanent solution, I think. The tSQLt Google Group is very helpful and has more info, too.

The latest version of tSQLt (the framework that underpins RedGate's SQL Test) now has an ApplyTrigger method which used in conjunction with FakeTable should allow you to do test your trigger. Not sure of this version is packaged up with SQL test yet though.

I have successfully used SQL Test with a more recent build of tSQLt (based on the SQL script download via but YMMV.
