The test creates a table and runs a number of queries on it to judge whether
the selected column types can hold the data they are expected to contain.
Additional test methods check the auto increment feature and a few of the
basic commands of db_tools. This is only a starting point. Plenty more
tests need to be added.

sql_buffer_nested_transactions to signal that buffering of the outer
results and closing of the outer transaction is required to open the
inner transaction.

Due to the usage of `__DIR__` for the file includes the tests can't
be ran on systems with PHP < 5.3. Replace all occurances of
`__DIR__` with `dirname(__FILE__)`.
