The FileDecoratorBase injects a new setUp & tearDown function. These new
functions would call the old setUp & tearDown in an inconvenient order: e.g. the
child class CopyFiles would at first call the user provided setUp and then copy
the files. This makes it impossible to perform some action on the file copy in
setUp.
=> This commit changes the call order, so that setUp & tearDown always "see" the
finished environment after file copies are in place and before any cleanup took
place.
- Refactor FileDecoratorBase to use an arbitrary property in the decorated
class where the list of files is saved
- Add DeleteFiles decorator which deletes all files passed to it after the test
finished
commands, retval, stdout & stderr are lists
if they don't have the same length, they are truncated to the smallest list
thereby silently dropping test cases
=> now a ValueError is raised preventing that
The testsuite now uses python's template module for string substitutions which
allows for a more natural substitution syntax known from the shell. Also, it
allows to run the substitutions multiple times, which is not possible with
string.format().
The heavy-lifting is now performed via a metaclass, which expands all variables
on the class creation.
