The session was 25 minutes. I couldn't cover every aspect...

To run the local test, simply cd into the directory containing the test, then
	qmake
	make check

You can open the test's .pro file in Qt Creator and run it. Note that some 
tests have subdirs and Creator may not have selected the test itself as the 
default project. The test is itself is usually "test".

My work pattern is
 1) start Creator, load the Qt 5 session (which already has corelib.pro open)
 2) make modifications to QtCore
 3) open the relevant test's .pro file
 4) write unit test
 5) Ctrl+R / F5
 6) rinse and repeat until satisfaction

If you're fixing bugs, you may want to write the unit test before fixing the 
code, so you can confirm that the test was failing before and now passing.

To push things to Gerrit and maintain my tree of changes, I use my own 
scripts.
