Test results should be logged as they are invoked, just like what happens in a regular TTY-based shell.

Test results are only logged after all the tests have run.

Regression:
N/A.

Notes:
N/A.

Simple workaround

Here is a very simple workaround, just set the NSUnbufferedIO environment variable to YES:

env NSUnbufferedIO=YES xcodebuild test

Apple Response

There are no plans to address this based on the following:

Jean-Pierre, you can install your own logging mechanism for XCTest by using the APIs in XCTestObservationCenter and then have to do any kind of logging you wish. To do so:

1) Register an NSPrincipalClass in your test bundle’s Info.plist
2) This class should conform to XCTestObservation
3) In the -init for your principal class, it should register with XCTestObservationCenter.
4) Implement the observation methods for test start, fail, finish, etc. and log the results however you want.

We are now closing this report.

If you have questions about the resolution, or if this is still a critical issue for you, then please update your bug report with that information.
