According to the docs importing pychecker only checks modules that are imported *after* the module containing the import. If you have a single-file program try using pychecker from the command line.

When you insert errors as a test, of course you have to use errors that are more subtle than syntax errors - things that would cause runtime errors. For example:

def f():
  x = y
