"""Generic testing tools that do NOT depend on Twisted.
|
|
|
|
|
|
In particular, this module exposes a set of top-level assert* functions that
|
|
|
can be used in place of nose.tools.assert* in method generators (the ones in
|
|
|
nose can not, at least as of nose 0.10.4).
|
|
|
|
|
|
Note: our testing package contains testing.util, which does depend on Twisted
|
|
|
and provides utilities for tests that manage Deferreds. All testing support
|
|
|
tools that only depend on nose, IPython or the standard library should go here
|
|
|
instead.

"""Make full paths for all the listed files, based on startPath.
|
|
|
|
|
|
Only the base part of startPath is kept, since this routine is typically

|
|
used with a script's __file__ variable as startPath. The base of startPath
|
|
|
is then prepended to all the listed files, forming the output list.

|
Parameters
|
|
|
----------
|
|
|
startPath : string
|
|
|
Initial path to use as the base for the results. This path is split
|
|
|
using os.path.split() and only its first component is kept.

|
|
|
|
|
files : string or list
|
|
|
One or more files.

|
Examples
|
|
|
--------
|
|
|
|
|
|
>>> full_path('/foo/bar.py',['a.txt','b.txt'])
|
|
|
['/foo/a.txt', '/foo/b.txt']

|
|
|
|
|
>>> full_path('/foo',['a.txt','b.txt'])
|
|
|
['/a.txt', '/b.txt']
|
|
|
|
|
|
If a single file is given, the output is still a list:

|
