Notes on writing new test files:
--------------------------------

A test file can contain anything, but usually it is similar to a regular input
file (defining a test problem), with a mandatory Test class. This class holds
all the test_* functions, as well as the from_conf(), which serves to
initialize the test (conf is in fact the test file itself, options are
command-line options).

All variables defined in a test file are collected in 'conf' variable passed to
a Test.__init__(). For example, 'input_name' in test_input_*.py files is
accessible as 'conf.input_name'. This is usefull if the test class is defined
outside the test file, as the classes in tests_basic.py are.

The test_* functions are collected automatically by run_tests.py, with one
exception: if a certain order of their evaluation is required, a class
attribute 'test' of the Test class with a list of the test function names
should be defined (example: test_meshio.py)."""
