+Some tips for the developer
+===========================
+
+This document exists so developers can write tips for other developers
+who need to add or fix tests to this environment.
+
+In a nutshell
+-------------
+
+The script `maas-package-test` calls nosetest3, which, in turn, runs
+`maas-integration.py`.
+
+
+Pausing the test
+----------------
+
+The `utils.py` file contains a handy function, `pause_until_released`,
+that writes a message to `/tmp/paused` and waits until the file is
+deleted. It can be used to pause the test program at any given time so
+you can ssh into the machine and inspect it. Another neat trick you can
+do is to stop the program before any test runs. You can then run the
+tests (and change the test-integration.py file to suit your needs). From
+a folder named like `/tmp/adt-run.Ezz1tN/build.mM6/real-tree`, run
+`nosetests3 --verbose --stop debian/tests/maas-integration.py` to start
+it.
