dd� Zdd� ZdS )�Plugina� Base class for nose plugins. It's recommended but not *necessary* to
subclass this class to create a plugin, but all plugins *must* implement
`options(self, parser, env)` and `configure(self, options, conf)`, and
must have the attributes `enabled`, `name` and `score`. The `name`
attribute may contain hyphens ('-').
Plugins should not be enabled by default.
Subclassing Plugin (and calling the superclass methods in
__init__, configure, and options, if you override them) will give
your plugin some friendly default behavior:
* A --with-$name option will be added to the command line interface
to enable the plugin, and a corresponding environment variable
will be used as the default value. The plugin class's docstring
will be used as the help for this option.
* The plugin will not be enabled unless this option is selected by
the user.

:type test: :class:`nose.case.Test`
Nr )r r8 r r r � afterTest� s zIPluginInterface.afterTestc C s dS )a� Called before a context (generally a module) is
examined. Because the context is not yet loaded, plugins don't
get to know what the context is; so any context operations
should use a stack that is pushed in `beforeContext` and popped
in `afterContext` to ensure they operate symmetrically.
`beforeContext` and `afterContext` are mainly useful for tracking
and restoring global state around possible changes from within a
context, whatever the context may be. If you need to operate on
contexts themselves, see `startContext` and `stopContext`, which
are passed the context in question, but are called after
it has been loaded (imported in the module case).

be some crazy name of your own devising, in which case, do
whatever you want.

:param parser: options parser instance
:type parser: :class:`ConfigParser.ConfigParser`
:param env: environment, default is os.environ
Nr )r r r r r r r � s zIPluginInterface.optionsc C s dS )a� Called before the test is run by the test runner. Please
note the article *the* in the previous sentence: prepareTest
is called *only once*, and is passed the test case or test
suite that the test runner will execute. It is *not* called
for each individual test case. If you return a non-None value,
that return value will be run as the test. Use this hook to
wrap or decorate the test with another function. If you need
to modify or wrap individual test cases, use `prepareTestCase`
instead.
:param test: the test case
:type test: :class:`nose.case.Test`
Nr )r r8 r r r � prepareTest s z IPluginInterface.prepareTestc C s dS )a� Prepare or wrap an individual test case. Called before
execution of the test. The test passed here is a
nose.case.Test instance; the case to be executed is in the
test attribute of the passed case. To modify the test to be
run, you should return a callable that takes one argument (the
test result object) -- it is recommended that you *do not*
side-effect the nose.case.Test instance you have been passed.
Keep in mind that when you replace the test callable you are
replacing the run() method of the test case -- including the
exception handling and result calls, etc.
:param test: the test case
:type test: :class:`nose.case.Test`
Nr )r r8 r r r �prepareTestCase s z IPluginInterface.prepareTestCasec C s dS )ah Called before tests are loaded. To replace the test loader,
return a test loader. To allow other plugins to process the
test loader, return None. Only one plugin may replace the test
loader. Only valid when using nose.TestProgram.
:param loader: :class:`nose.loader.TestLoader`
(or other loader) instance
Nr )r �loaderr r r �prepareTestLoader) s z"IPluginInterface.prepareTestLoaderc C s dS )ab Called before the first test is run. To use a different
test result handler for all tests than the given result,
return a test result handler. NOTE however that this handler
will only be seen by tests, that is, inside of the result
proxy system. The TestRunner and TestProgram -- whether nose's
or other -- will continue to see the original result
handler. For this reason, it is usually better to monkeypatch
the result (for instance, if you want to handle some
exceptions in a unique way). Only one plugin may replace the
result, but many may monkeypatch it. If you want to
monkeypatch and stop other plugins from doing so, monkeypatch
and return the patched result.
:param result: :class:`nose.result.TextTestResult`
(or other result) instance
Nr )r rK r r r �prepareTestResult5 s z"IPluginInterface.prepareTestResultc C s dS )a2 Called before tests are run. To replace the test runner,
return a test runner. To allow other plugins to process the
test runner, return None. Only valid when using nose.TestProgram.
:param runner: :class:`nose.core.TextTestRunner`
(or other runner) instance
Nr )r �runnerr r r �prepareTestRunnerI s z"IPluginInterface.prepareTestRunnerc C s dS )a2 Called after all error output has been printed. Print your

other plugins to print reports, any other value to stop them.
:param stream: stream object; send your output here
:type stream: file-like object
Nr )r �streamr r r �reportT s zIPluginInterface.reportc C s dS )ad Called before test output begins. To direct test output to a
new stream, return a stream object, which must implement a
`write(msg)` method. If you only want to note the stream, not
capture or redirect it, then return None.
:param stream: stream object; send your output here
:type stream: file-like object
Nr )r re r r r �setOutputStream^ s z IPluginInterface.setOutputStreamc C s dS )a3 Called before context setup and the running of tests in the
context. Note that tests have already been *loaded* from the
context before this call.
:param context: the context about to be setup. May be a module or
class, or any other object that contains tests.
Nr )r �contextr r r � startContexth s z IPluginInterface.startContextc C s dS )z�Called before each test is run. DO NOT return a value unless
you want to stop other plugins from seeing the test start.
:param test: the test case
:type test: :class:`nose.case.Test`
Nr )r r8 r r r � startTests s zIPluginInterface.startTestc C s dS )z�Called after the tests in a context have run and the
