Refactored tests to use a documented and, hopefully, sane, testing 

API. This allowed the tests to be simplified somewhat.

Testing Support
===============
The zc.buildout.testing module provides an API that can be used when
writing recipe tests. This API is documented below. Many examples of
using this API can be found in the zc.buildout, zc.recipe.egg, and
zc.recipe.testrunner tests.
zc.buildout.testing.buildoutSetUp(test)
---------------------------------------
The buildoutSetup function can be used as a doctest setup function.
It performs adds a number of names to the test namespace:
sample_buildout
This is the name of a buildout with a basic configuration.
ls(*path)
List the contents of a directory. The directory path is provided as one or
more strings, to be joined with os.path.join.
cat(*path)
Display the contents of a file. The file path is provided as one or
more strings, to be joined with os.path.join.
On Windows, if the file doesn't exist, the function will try
adding a '-script.py' suffix. This helps to work around a
difference in script generation on windows.
mkdir(*path)
Create a directory. The directory path is provided as one or
more strings, to be joined with os.path.join.
rmdir(*path)
Remove a directory. The directory path is provided as one or
more strings, to be joined with os.path.join.
tmpdir(name)
Create a temporary directory with the given name. The directory
will be automatically removed at the end of the test. The path of
the created directory is returned.
Further, if the the normalize_path normlaizing substitution (see
below) is used, then any paths starting with this path will be
normalized to::
/name/restofpath
No two temporary directories can be created with the same name. A
directory created with tmpdir can be removed with rmdir and recreated.
Note that the sample_buildout directory is created by calling this
function.
write(*path_and_contents)
Create a file. The file path is provided as one or more strings,
to be joined with os.path.join. The last argument is the file contents.
system(command, input='')
Execute a system command with the given input passed to the
command's standard input. The output (error and regular output)
from the command is returned.
get(url)
Get a web page.
cd(*path)
Change to the given directory. The directory path is provided as one or
more strings, to be joined with os.path.join.
The directory will be reset at the end of the test.
join(*path)
A convenient reference to os.path.join.
register_teardown(func)
Register a tear-down function. The function will be called with
no arguments at the end of the test.
start_server(path)
Start a web server on the given path. The server will be shut
down at the end of the test. The server URL is returned.
sdist(setup, dest)
Create a source distribution by running the given setup file and
placing the result in the given destination directory. If the
setup argument is a directory, the thge setup.py file in that
directory is used.
bdist_egg(setup, executable, dest)
Create an egg by running the given setup file with the given
Python executable and placing the result in the given destination
directory. If the setup argument is a directory, the thge
setup.py file in that directory is used.
find_python(version)
Find a Python executable for the given version, where version is a
string like "2.4".
This function uses the following strategy to find a Python of the
given version:
- Look for an environment variable of the form PYTHON%(version)s.
- On windows, look for \Pythonm%(version)s\python
- on Unix, try running python%(version)s or just python to get the
executable
zc.buildout.testing.buildoutTearDown(test)
------------------------------------------
Tear down everything set up by zc.buildout.testing.buildoutSetUp. Any
functions passed to register_teardown are called as well.
install(project, destination)
-----------------------------
Install eggs for a given project into a destination. If the
destination is a test object, then the eggs directory of the
sample buildout (sample_buildout) defined by the test will be used.
Tests will use this to install the distributions for the packages
being tested (and their dependencies) into a sample buildout. The egg
to be used should already be loaded, by importing one of the modules
provided, before calling this function.
install_develop(project, destination)
-------------------------------------
Like install, but a develop egg is installed even if the current egg
if not a develop egg.
Output normalization
--------------------
Recipe tests often generate output that is dependent on temporary file
locations, operating system conventions or Python versions. To deal
with these dependencies, we often use
zope.testing.renormalizing.RENormalizing to normalize test output.
zope.testing.renormalizing.RENormalizing takes pairs of regular
expressions and substitutions. The zc.buildout.testing module provides
a few helpful variables that define regular-expression/substitution
pairs that you can pass to zope.testing.renormalizing.RENormalizing.
normalize_path
Converts tests paths, based on directories created with tmpdir(),
to simple paths.
normalize_script
On Unix-like systems, scripts are implemented in single files
without suffixes. On windows, scripts are implemented with 2
files, a -script.py file and a .exe file. This normalization
converts directory listings of Windows scripts to the form
generated on UNix-like systems.
normalize_egg_py
Normalize Python version and platform indicators, if specified, in
egg names.
