+BIND10 system testing with Lettuce
+or: to BDD or not to BDD
+
+In this directory, we define a set of behavioral tests for BIND 10. Currently,
+these tests are specific for BIND10, but we are keeping in mind that RFC-related
+tests could be separated, so that we can test other systems as well.
+
+Prerequisites:
+- Installed version of BIND 10 (but see below how to run it from source tree)
+- dig
+- lettuce (http://lettuce.it)
+
+To install lettuce, if you have the python pip installation tool, simply do
+pip install lettuce
+See http://lettuce.it/intro/install.html
+
+Most systems have the pip tool in a separate package; on Debian-based systems
+it is called python-pip. On FreeBSD the port is devel/py-pip.
+
+Running the tests
+-----------------
+
+At this moment, we have a fixed port for local tests in our setups, port 47806.
+This port must be free. (TODO: can we make this run-time discovered?).
+Port 47805 is used for cmdctl, and must also be available.
+(note, we will need to extend this to a range, or if possible, we will need to
+do some on-the-fly available port finding)
+
+The bind10 main program, bindctl, and dig must all be in the default search 
+path of your environment, and BIND 10 must not be running if you use the 
+installed version when you run the tests.
+
+If you want to test an installed version of bind 10, just run 'lettuce' in
+this directory.
+
+We have provided a script that sets up the shell environment to run the tests
+with the build tree version of bind. If your shell uses export to set
+environment variables, you can source the script setup_intree_bind10.sh, then
+run lettuce.
+
+Due to the default way lettuce prints its output, it is advisable to run it
+in a terminal that is wide than the default. If you see a lot of lines twice
+in different colors, the terminal is not wide enough.
+
+If you just want to run one specific feature test, use
+lettuce features/<feature file>
+
+To run a specific scenario from a feature, use
+lettuce features/<feature file> -s <scenario number>
+
+We have set up the tests to assume that lettuce is run from this directory,
+so even if you specify a specific feature file, you should do it from this
+directory.
+
+What to do when a test fails
+----------------------------
+
+First of all, look at the error it printed and see what step it occurred in.
+If written well, the output should explain most of what went wrong.
+
+The stacktrace that is printed is *not* of bind10, but of the testing
+framework; this helps in finding more information about what exactly the test
+tried to achieve when it failed (as well as help debug the tests themselves).
+
+Furthermore, if any scenario fails, the output from long-running processes
+will be stored in the directory output/. The name of the files will be
+<Feature name>-<Scenario name>-<Process name>.stdout and
+<Feature name>-<Scenario name>-<Process name>.stderr
+Where spaces and other non-standard characters are replaced by an underscore.
+The process name is either the standard name for said process (e.g. 'bind10'),
+or the name given to it by the test ('when i run bind10 as <name>').
+
+These files *will* be overwritten or deleted if the same scenarios are run
+again, so if you want to inspect them after a failed test, either do so
+immediately or move the files.
+
+Adding and extending tests
+--------------------------
+
+If you want to add tests, it is advisable to first go through the examples to
+see what is possible, and read the documentation on http://www.lettuce.it
+
+There is also a README.tutorial file here.
+
+We have a couple of conventions to keep things manageable.
+
+Configuration files go into the configurations/ directory.
+Data files go into the data/ directory.
+Step definition go into the features/terrain/ directory (the name terrain is 
+chosen for the same reason Lettuce chose terrain.py, this is the place the 
+tests 'live' in).
+Feature definitions go directly into the features/ directory.
+
+These directories are currently not divided further; we may want to consider 
+this as the set grows. Due to a (current?) limitation of Lettuce, for 
+feature files this is currently not possible; the python files containing 
+steps and terrain must be below or at the same level of the feature files.
+
+Long-running processes should be started through the world.RunningProcesses
+instance. If you want to add a process (e.g. bind9), create start, stop and
+control steps in terrain/<base_name>_control.py, and let it use the
+RunningProcesses API (defined in terrain.py). See bind10_control.py for an
+example.
+
+For sending queries and checking the results, steps have been defined in
+terrain/querying.py. These use dig and store the results split up into text
+strings. This is intentionally not parsed through our own library (as that way
+we might run into a 'symmetric bug'). If you need something more advanced from
+query results, define it here.
+
+Some very general steps are defined in terrain/steps.py.
+Initialization code, cleanup code, and helper classes are defined in
+terrain/terrain.py.
+
+To find the right steps, case insensitive matching is used. Parameters taken
+from the steps are case-sensitive though. So a step defined as
+'do foo with value (bar)' will be matched when using
+'Do Foo with value xyz', but xyz will be taken as given.
+
+If you need to add steps that are very particular to one test, create a new 
+file with a name relevant for that test in terrain. We may want to consider 
+creating a specific subdirectory for these, but at this moment it is unclear 
+whether we need to.
+
+We should try to keep steps as general as possible, while not making them to
+complex and error-prone.

+Quick tutorial and overview
+---------------------------
+
+Lettuce is a framework for doing Behaviour Driven Development (BDD).
+
+The idea behind BDD is that you first write down your requirements in
+the form of scenarios, then implement their behaviour.
+
+We do not plan on doing full BDD, but such a system should also help
+us make system tests. And, hopefully, being able to better identify
+what exactly is going wrong when a test fails.
+
+Lettuce is a python implementation of the Cucumber framework, which is
+a ruby system. So far we chose lettuce because we already need python
+anyway, so chances are higher that any system we want to run it on
+supports it. It only supports a subset of cucumber, but more cucumber
+features are planned. As I do not know much details of cucumber, I
+can't really say what is there and what is not.
+
+A slight letdown is that the current version does not support python 3.
+However, as long as the tool-calling glue is python2, this should not
+cause any problems, since these aren't unit tests; We do not plan to use
+our libraries directly, but only through the runnable scripts and
+executables.
+
+-----
+
+Features, Scenarios, Steps.
+
+Lettuce makes a distinction between features, scenarios, and steps.
+
+Features are general, well, features. Each 'feature' has its own file
+ending in .feature. A feature file contains a description and a number
+of scenarios. Each scenario tests one or more particular parts of the
+feature. Each scenario consists of a number of steps.
+
+So let's open up a simple one.
+
+-- example.feature
+Feature: showing off BIND 10
+    This is to show BIND 10 running and that it answer queries
+
+    Scenario: Starting bind10
+        # steps go here
+--
+
+I have predefined a number of steps we can use, as we build test we
+will need to expand these, but we will look at them shortly.
+
+This file defines a feature, just under the feature name we can
+provide a description of the feature.
+
+The one scenario we have no has no steps, so if we run it we should
+see something like:
+
+-- output
+> lettuce
+Feature: showing off BIND 10
+  This is to show BIND 10 running and that it answer queries
+
+  Scenario: Starting bind10
+
+1 feature (1 passed)
+1 scenario (1 passed)
+0 step (0 passed)
+--
+
+Let's first add some steps that send queries.
+
+--
+        A query for www.example.com should have rcode REFUSED
+        A query for www.example.org should have rcode NOERROR
+--
+
+Since we didn't start any bind10, dig will time out and the result
+should be an error saying it got no answer. Errors are in the
+form of stack traces (trigger by failed assertions), so we can find
+out easily where in the tests they occurred. Especially when the total
+set of steps gets bigger we might need that.
+
+So let's add a step that starts bind10.
+
+--
+        When I start bind10 with configuration example.org.config
+--
+
+This is not good enough; it will fire of the process, but setting up
+b10-auth may take a few moments, so we need to add a step to wait for
+it to be started before we continue.
+
+--
+        Then wait for bind10 auth to start
+--
+
+And let's run the tests again.
+
+--
+> lettuce
+
+Feature: showing off BIND 10
+  This is to show BIND 10 running and that it answer queries
+
+  Scenario: Starting bind10
+    When I start bind10 with configuration example.org.config
+    Then wait for bind10 auth to start
+    A query for www.example.com should have rcode REFUSED
+    A query for www.example.org should have rcode NOERROR
+
+1 feature (1 passed)
+1 scenario (1 passed)
+4 steps (4 passed)
+(finished within 2 seconds)
+--
+
+So take a look at one of those steps, let's pick the first one.
+
+A step is defined through a python decorator, which in essence is a regular
+expression; lettuce searches through all defined steps to find one that
+matches. These are 'partial' matches (unless specified otherwise in the
+regular expression itself), so if the step is defined with "do foo bar", the
+scenario can add words for readability "When I do foo bar".
+
+Each captured group will be passed as an argument to the function we define.
+For bind10, i defined a configuration file, a cmdctl port, and a process
+name. The first two should be self-evident, and the process name is an
+optional name we give it, should we want to address it in the rest of the
+tests. This is most useful if we want to start multiple instances. In the
+next step (the wait for auth to start), I added a 'of <instance>'. So if we 
+define the bind10 'as b10_second_instance', we can specify that one here as 
+'of b10_second_instance'.
+
+--
+        When I start bind10 with configuration second.config
+        with cmdctl port 12345 as b10_second_instance
+--
+(line wrapped for readability)
+
+But notice how we needed two steps, which we probably always need (but
+not entirely always)? We can also combine steps; for instance:
+
+--
+@step('have bind10 running(?: with configuration ([\w.]+))?')
+def have_bind10_running(step, config_file):
+    step.given('start bind10 with configuration ' + config_file)
+    step.given('wait for bind10 auth to start')
+--
+
+Now we can replace the two steps with one:
+
+--
+    Given I have bind10 running
+--
+
+That's it for the quick overview. For some more examples, with comments, 
+take a look at features/example.feature. You can read more about lettuce and
+its features on http://www.lettuce.it, and if you plan on adding tests and
+scenarios, please consult the last section of the main README first.

+    The first scenario is to show what a simple test would look like, and
