Hello guys!

I am doing this experiment on Code Review on GitLab. The idea is that I have created a tool to enhance the GitLab UI, and I want to test out whether it's actually useful and helpful.
It would really mean a lot to me if you could participate in this experiment. I leave you here the link and the details:

The experiment should require around 15 minutes (it's a code review of 6 Java files).

Please let me know if you have further questions!

PS: by participating, it's not sure you're gonna end up in the test group (the one with the new GitLab UI), you might end up in the control group (the one with the normal UI).
Please send me a message if you want further details

Thank you,

Hi guys,
I am investigating the order in which we start reviewing files (namely from test or production files), and why.

I created a 2 minutes survey with these question.
Here is the link:

Thank you for the attention, and if you want to be updated with the results, write me your email

Hey guys,
I was interviewing developers, and it appears to me that some developers prefer to start reviewing from the test and then look at the real code (production code), and other developers do vice-versa.
I am trying to write a sort of tutorial (kind of best practices among developers), and I wanted to know your opinion.

Question 1: Which order do you prefer? And why?
Question 2: Are there occasions in which you prefer one over the other?
Question 3: Main advantages of starting with tests?

Thank you for your opinion!

Sorry for that! I had to restart the server due to a network failure. So a couple of experiments were gone. Now everything should be ok!

For the "Toggle button":
I divided the review in 2 parts, and you can see only 1 part at the time.
I can't reveal the rationale behind (otherwise I bias you ;) ).
With that button you can look at the other part of the review. Small things to say is that some reviews do not contains a "second part" (still part of the experiment and I can't say why), so if you press it nothing happens!

Thanks for participating and if you have further questions, I am here!

Hi guys! I am Davide, a PhD student at TU Delft (NL) and I am investigating in best practices in code review.
It would be very helpful if you could participate in my experiment, in which you have to review 2 small changes,
it's funny and it won't take a lot of time! The experiment is online, so you can do it whenever you prefer!

The link to the experiment is:

And if you know other people who could participate, please send them the link!
Thank you very much for your help!
