How to delete unapproved app from iTunes Connect?

I'm using now the new Apple service for testing apps. I know that the process to send an app for test is:

Create an ID
Create the certificates
Create an app in iTunesConnect
Archive, upload and invite internal or external test.

But not all apps that I create in my account (iTunesConnect) go to be public; because a lot of my app finish published in the accounts of my costumers. In this way in my iTunesConnect I have a lot of: (for example)

App1 Test
App2 Test
App3 test ....

I want to delete these, is there a way?

If what I wrote is wrong, so there is another way more intelligent to follow, tell me please!

Solution

Unfortunately, you cannot delete apps from iTunes Connect unless one or more versions of the app have been approved by Apple's review team. According to their documentation:

You can delete your app if there is at least one approved version of the app

Honestly, aside from the annoyance of seeing old unused apps there, there isn't much of a problem with what you're doing. What you could do to reduce the number of "junk" apps in your portal is to re-use app identifiers after the TestFlight testing time of 30 days expires (and, of course, you'll have to clear out those beta testers).
