+OONI, the Open Observatory of Network Interference, is a global observation

+using Free and Open Source Software (FL/OSS) to share observations and data
+about the various types, methods, and amounts of network tampering in the world.

-*The "hard" way*
-
-This involves installing the dependencies installable via easy_install/pip and

+Installing OONI
+===============
+
+Currently no installation documentation is present, since OONI is not meant to
+be installed and should be handled with care.
+
+Dependencies
+************
+
+OONI depends on the following pieces of software.
+
+* Twisted: http://twistedmatrix.com/trac/
+* PyYAML: http://pyyaml.org/
+* Scapy: http://www.secdev.org/projects/scapy/
+ * pypcap: http://code.google.com/p/pypcap/
+ * libdnet: http://code.google.com/p/libdnet/
+
+*Optional*
+
+* BeautifulSoup: http://www.crummy.com/software/BeautifulSoup/
+
+Manual installation of scapy
+----------------------------
+
+It is optimal to install scapy, libdnet and pypcap from source. This can be
+done with the following code snippets.
+
+libdnet::
+
+ wget http://libdnet.googlecode.com/files/libdnet-1.12.tgz
+ tar xzf libdnet-1.12.tgz

-==================
Writing OONI tests
==================
-OONIProbe tests can be written in two modes: blocking or non-blocking.
-Going the blocking route is not advised and all tests in the end should end up
-being written in the non-blocking way.
+The OONI testing API is heavily influenced and partially based on the python
+:class:`unittest` module and :class:`twsted.trial`.
+
+
+Test Cases
+----------
+
+The atom of OONI Testing is called a Test Case. A test case class may contain
+multiple Test Functions.
+
+.. autoclass:: ooni.nettest.TestCase
+
+:class:`ooni.nettest.TestCase` is a subclass of :class:`unittest.TestCase` so
+the assert methods that apply to :class:`unittest.TestCase` will also apply to
+:class:`ooni.nettest.TestCase`.
+
+If the test you plan to write is not listed on the `Tor OONI trac page
+<https://trac.torproject.org/projects/tor/wiki/doc/OONI/Tests>`_, you should
+add it to the list and following the `test template
+<https://trac.torproject.org/projects/tor/wiki/doc/OONI/Tests/TestTemplate>`_
+write up a description about it.
+
+
+Inputs
+------
+
+Inputs are what is given as input to every iteration of the Test Case. You have
+100 inputs, then every test case will be run 100 times.
+
+To configure a static set of inputs you should define the
+:class:`ooni.nettest.TestCase` attribute ``inputs``. The test will be run ``len(inputs)`` times. Any iterable object is a valid ``inputs`` attribute.
+
+If you would like to have inputs be determined from a user specified input
+file, then you must set the ``inputFile`` attribute. This is an array that
+specifies what command line option may be used to control this value.
+
+By default the ``inputProcessor`` is set to read the file line by line and
+strip newline characters. To change this behavior you must set the
+``inputProcessor`` attribute to a function that takes as arugment a file
+descriptor and yield the next item. The default ``inputProcessor`` looks like
+this::
+
+
+ def lineByLine(fp):
+ for x in fp.readlines():
+ yield x.strip()
+ fp.close()
+
+
+Test Functions
+--------------
+
+These shall be defined inside of your :class:`ooni.nettest.TestCase` subclass.
+These will be class methods.
-A good way to understand how to write a test is also to take a look at the OONI
-Test Interface in the following files:
+To add data to the test report you may write directly to the report object like
+so::
-* ooni/plugoo/interface.py
+ def my_test_function():
+ result = do_something()
+ self.report['something'] = result
-* ooni/plugoo/tests.py
+OONI will then handle the writing of the data to the final test report.
-Writing non-blocking tests
---------------------------
+To access the current input you can use the ``input`` attribute, for example::
-To bootstrap the process of creating a new tests you can run the scaffolding
-script in ooni/scaffolding.py.
+ def my_test_with_input():
+ do_something_with_input(self.input)
-This will create a new plugin with the specified name inside of ooni/plugins/.
+This will at each iteration over the list of inputs do something with the
+input.

-= Writing OONI Tests =
-
-There are two modes of writing tests. The first way is by making the Test
-blocking and have each instance of a test run in a separate thread. The other
-is by making them non-blocking using the twisted deferred non blocking pattern.
-
-The first kind of mechanism relied of writing a test that uses blocking code
-and each instance of it is run inside of a separate thread. Beware that your
-blocking code must be thread safe to run properly (as is obvious :P)
-
-The other menthod invloves having some knowledge about twisted. The test you
-will write will be written in twisted and should implement async style non
-blocking architecture.
-
-It is recommended that tests are written using the second pattern and the first
-should only be used for runnign tests that have been previously written.
