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
