Comparing Qlik App Output Before vs. After Development Changes

[newuser]

When making substantial changes to a Qlik app, it is sometimes essential to do compares on the Qlik outputs before vs. after changes. My approaches to such compares has been dumping key data to Excel from key visualizations from "before" vs. "after" copies of the app to verify the impact of the changes.

Has anyone else found a more efficient way to execute such comparisons? Stories don't allow for the data compare that shipping to Excel would ... Another thought was to create an nPrinting report, but these sorts of compares are ad hoc in nature, so creating an Excel nPrinting report that could be reused would take some careful thought.

In the past I've had great success using the Regression Test feature of the Qlik Scalability Tools.  Takes a bit to set it up, but the results are magic. A full report of all output differences.

Does that tool allow for automated DATA compares before vs. after? Seems mainly performance testing driven? Is there a demo available for this? I assume a separate cost/license

It's a free tool.

Yes, it does automated compare of before/after data when you set the test type to regression. In that case it simulates just one user and collects all the data. 

I will say that last time I did this I used the older version of the tool

and it worked very well.  I'm not absolutely sure that the newer version of the tool supports regression tests, but I'm guessing it does.
