Return to Question

I am trying to run the full set of standard integration tests, which I want to run before deployments on an continuous integration server. (Whilst developing I will run just for my own module using the methodology from here.)

P.S. I have read @Fabian-Schmengler question but whilst the thrown error obscuring the root cause is similar, I'm not sure how to apply that knowledge to tracking down the problem with data installation.

I noticed that it is running a comand line installation of:

&MAGE_MODE=developer' 2>&1

so I ran this actually at the command line... weirdly even though the verbosity level -vvv is set to debug, the above produces no output and just quits out...

Edit: Doh... just noticed it's redirecting standard output - trying again without the 2>&1

What are my steps for debugging, namely:

1. How does Magento produce the SQL that it is trying to install
2. Is it cached anywhere as a physical file I can read
3. How can I find more useful information tracking the problem down
