Hello Hackers,
We reviewed the PR, and there are a lot of new lines of code in this patch, are we sure that we can have a good coverage of the functionality just by doing feature tests?
Adding more code to a 3.5k+ lines file doesn't look like a good option, do you think it is possible to extract some of the functionality to their own files and have test around those functionalities?
Do we really need to have an epicRandomString function in our code? Would it be better to use a library that would provide us that functionality out of the box?
The functions this.applyValue in slick.pgadmin.editors.js that were change in this patch are exactly the same, can we extract that code into a single function instead of repeating the code?
Using feature tests is a good option to ensure that the integration of all the components of the application is working as expected, but in order to tests behaviors that are edge cases the Unit Tests are much cheaper to run and create.
Thanks
Joao & Shruti

Now copied row will add to grid instead of re-rendering all rows again.5) Moved the common logic into functions.This patch pass the feature test cases and jasmine test case.Also I will add the test cases for copy row and send an updated patch.Please find attached patch and review.Looks good. I saw the following issues:- The "new" row is not available once I've created the first new row, or pasted some.Fixed.- Rows are pasted in reverse order.Fixed.- If I copy/paste a new row that has yet to be saved, none of the values are actually copied.Fixed.- Attempting to save a row that contains all null/default values results in an invalid query:INSERT INTO public.defaults () VALUES ();I think the only answer here is to explicitly insert NULL into any columns *without* a default value.I could not reproduce, However #3 might have fixed it too.Apart from this, I noticed epicRandomString(...) function doesn't generate unique number always, due to this save and delete rows was affected. Not all rows saved or deleted. The new function always returns a unique random number.Fixed.--Thanks.Dave Page
