Test the manifest parser
========================

You must have ManifestDestiny installed before running these tests.
Run ``python manifestparser.py setup develop`` with setuptools installed.

Ensure basic parser is sane::

    >>> from manifestparser import ManifestParser
    >>> parser = ManifestParser()
    >>> parser.read('mozmill-example.ini')
    >>> tests = parser.tests
    >>> len(tests) == len(file('mozmill-example.ini').read().strip().splitlines())
    True
    
Ensure that capitalization and order aren't an issue:

    >>> lines = ['[%s]' % test['name'] for test in tests]
    >>> lines == file('mozmill-example.ini').read().strip().splitlines()
    True

Show how you select subsets of tests:

    >>> parser.read('mozmill-restart-example.ini')
    >>> restart_tests = parser.get(type='restart')
    >>> len(restart_tests) < len(parser.tests)
    True
    >>> import os
    >>> len(restart_tests) == len(parser.get(manifest=os.path.abspath('mozmill-restart-example.ini')))
    True
    >>> assert not [test for test in restart_tests if test['manifest'] != os.path.abspath('mozmill-restart-example.ini')]
    >>> parser.get('name', tags=['foo'])
    ['restartTests/testExtensionInstallUninstall/test2.js', 'restartTests/testExtensionInstallUninstall/test1.js']
    >>> parser.get('name', foo='bar')
    ['restartTests/testExtensionInstallUninstall/test2.js']

Illustrate how include works::

    >>> parser = ManifestParser(manifests=('include-example.ini',))

All of the tests should be included, in order::

    >>> parser.get('name')
    ['crash-handling', 'fleem', 'flowers']
    >>> [(test['name'], os.path.basename(test['manifest'])) for test in parser.tests]
    [('crash-handling', 'bar.ini'), ('fleem', 'include-example.ini'), ('flowers', 'foo.ini')]

The manifests should be there too::

    >>> len(parser.manifests())
    3

We're already in the root directory::

    >>> os.getcwd() == parser.rootdir
    True

DEFAULT values should persist across includes, unless they're
overwritten.  In this example, include-example.ini sets foo=bar, but
its overridden to fleem in bar.ini::

    >>> parser.get('name', foo='bar')
    ['fleem', 'flowers']
    >>> parser.get('name', foo='fleem')
    ['crash-handling']

Passing parameters in the include section allows defining variables in
the submodule scope:

    >>> parser.get('name', tags=['red'])
    ['flowers']

However, this should be overridable from the DEFAULT section in the
included file and that overridable via the key directly connected to
the test::

    >>> parser.get(name='flowers')[0]['blue']
    'ocean'
    >>> parser.get(name='flowers')[0]['yellow']
    'submarine'

You can query multiple times if you need to::

    >>> flowers = parser.get(foo='bar')
    >>> len(flowers)
    2
    >>> roses = parser.get(tests=flowers, red='roses')

Using the inverse flag should invert the set of tests returned::

    >>> parser.get('name', inverse=True, tags=['red'])
    ['crash-handling', 'fleem']

All of the included tests actually exist::

    >>> [i['name'] for i in parser.missing()]
    []

Write the output to a manifest:

    >>> from StringIO import StringIO
    >>> buffer = StringIO()
    >>> parser.write(fp=buffer, global_kwargs={'foo': 'bar'})
    >>> buffer.getvalue().strip()
    '[DEFAULT]\nfoo = bar\n\n[fleem]\n\n[include/flowers]\nblue = ocean\nred = roses\nyellow = submarine'

Test our ability to convert a static directory structure to a
manifest. First, stub out a directory with files in it::

    >>> import shutil, tempfile
    >>> def create_stub():
    ...     directory = tempfile.mkdtemp()
    ...     for i in 'foo', 'bar', 'fleem':
    ...         file(os.path.join(directory, i), 'w').write(i)
    ...     subdir = os.path.join(directory, 'subdir')
    ...     os.mkdir(subdir)
    ...     file(os.path.join(subdir, 'subfile'), 'w').write('baz')
    ...     return directory
    >>> stub = create_stub()
    >>> os.path.exists(stub) and os.path.isdir(stub)
    True

Make a manifest for it::

    >>> from manifestparser import convert
    >>> print convert([stub])
    [bar]
    [fleem]
    [foo]
    [subdir/subfile]
    >>> shutil.rmtree(stub)

Now do the same thing but keep the manifests in place::

    >>> stub = create_stub()
    >>> convert([stub], write='manifest.ini')
    >>> sorted(os.listdir(stub))
    ['bar', 'fleem', 'foo', 'manifest.ini', 'subdir']
    >>> parser = ManifestParser()
    >>> parser.read(os.path.join(stub, 'manifest.ini'))
    >>> [i['name'] for i in parser.tests]
    ['subfile', 'bar', 'fleem', 'foo']
    >>> parser = ManifestParser()
    >>> parser.read(os.path.join(stub, 'subdir', 'manifest.ini'))
    >>> len(parser.tests)
    1
    >>> parser.tests[0]['name']
    'subfile'
    >>> shutil.rmtree(stub)

Test our ability to copy a set of manifests::

    >>> tempdir = tempfile.mkdtemp()
    >>> manifest = ManifestParser(manifests=('include-example.ini',))
    >>> manifest.copy(tempdir)
    >>> sorted(os.listdir(tempdir))
    ['fleem', 'include', 'include-example.ini']
    >>> sorted(os.listdir(os.path.join(tempdir, 'include')))
    ['bar.ini', 'crash-handling', 'flowers', 'foo.ini']
    >>> from_manifest = ManifestParser(manifests=('include-example.ini',))
    >>> to_manifest = os.path.join(tempdir, 'include-example.ini')
    >>> to_manifest = ManifestParser(manifests=(to_manifest,))
    >>> to_manifest.get('name') == from_manifest.get('name')
    True
    >>> shutil.rmtree(tempdir)

Test our ability to update tests from a manifest and a directory of
files::

    >>> tempdir = tempfile.mkdtemp()
    >>> for i in range(10):
    ...     file(os.path.join(tempdir, str(i)), 'w').write(str(i))

First, make a manifest::

    >>> manifest = convert([tempdir])
    >>> newtempdir = tempfile.mkdtemp()
    >>> manifest_file = os.path.join(newtempdir, 'manifest.ini')
    >>> file(manifest_file,'w').write(manifest)
    >>> manifest = ManifestParser(manifests=(manifest_file,))
    >>> manifest.get('name') == [str(i) for i in range(10)]
    True

All of the tests are initially missing::

    >>> [i['name'] for i in manifest.missing()] == [str(i) for i in range(10)]
    True

But then we copy one over::

    >>> manifest.get('name', name='1')
    ['1']
    >>> manifest.update(tempdir, name='1')
    >>> sorted(os.listdir(newtempdir))
    ['1', 'manifest.ini']

Update that one file and copy all the "tests"::
   
    >>> file(os.path.join(tempdir, '1'), 'w').write('secret door')
    >>> manifest.update(tempdir)
    >>> sorted(os.listdir(newtempdir))
    ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'manifest.ini']
    >>> file(os.path.join(newtempdir, '1')).read().strip()
    'secret door'

Clean up::

    >>> shutil.rmtree(tempdir)
    >>> shutil.rmtree(newtempdir)

You can override the path in the section too.  This shows that you can
use a relative path::

    >>> manifest = ManifestParser(manifests=('path-example.ini',))
    >>> manifest.tests[0]['path'] == os.path.abspath('fleem')
    True
