+Introduction
+============
+
+PyHamcrest is a framework for writing matcher objects, allowing you to
+declaratively define "match" rules. There are a number of situations where
+matchers are invaluable, such as UI validation, or data filtering, but it is in
+the area of writing flexible tests that matchers are most commonly used. This
+tutorial shows you how to use PyHamcrest for unit testing.
+
+When writing tests it is sometimes difficult to get the balance right between
+overspecifying the test (and making it brittle to changes), and not specifying
+enough (making the test less valuable since it continues to pass even when the
+thing being tested is broken). Having a tool that allows you to pick out
+precisely the aspect under test and describe the values it should have, to a
+controlled level of precision, helps greatly in writing tests that are "just
+right." Such tests fail when the behavior of the aspect under test deviates
+from the expected behavior, yet continue to pass when minor, unrelated changes
+to the behaviour are made.
+
+Installation
+============
+
+Hamcrest can be installed using the usual Python packaging tools. It depends on
+distribute, but as long as you have a network connection when you install, the
+installation process will take care of that for you.
+
+My first PyHamcrest test
+========================
+
+We'll start by writing a very simple PyUnit test, but instead of using PyUnit's
+``assertEqual`` method, we'll use PyHamcrest's ``assert_that`` construct and
+the standard set of matchers:
+
+.. code:: python
+
+ from hamcrest import *
+ import unittest
+
+ class BiscuitTest(unittest.TestCase):
+ def testEquals(self):
+ theBiscuit = Biscuit('Ginger')
+ myBiscuit = Biscuit('Ginger')
+ assert_that(theBiscuit, equal_to(myBiscuit))
+
+ if __name__ == '__main__':
+ unittest.main()
+
+The ``assert_that`` function is a stylized sentence for making a test
+assertion. In this example, the subject of the assertion is the object
+``theBiscuit``, which is the first method parameter. The second method
+parameter is a matcher for ``Biscuit`` objects, here a matcher that checks one
+object is equal to another using the Python ``==`` operator. The test passes
+since the ``Biscuit`` class defines an ``__eq__`` method.
+
+If you have more than one assertion in your test you can include an identifier
+for the tested value in the assertion:
+
+.. code:: python
+
+ assert_that(theBiscuit.getChocolateChipCount(), equal_to(10), 'chocolate chips')
+ assert_that(theBiscuit.getHazelnutCount(), equal_to(3), 'hazelnuts')
+
+As a convenience, assert_that can also be used to verify a boolean condition:
+
+.. code:: python
+
+ assert_that(theBiscuit.isCooked(), 'cooked')
+
+This is equivalent to the ``assert_`` method of unittest.TestCase, but because
+it's a standalone function, it offers greater flexibility in test writing.
+
+
+Predefined matchers
+===================
+
+PyHamcrest comes with a library of useful matchers:
+
+* Object
+
+ * ``equal_to`` - match equal object
+ * ``has_length`` - match ``len()``
+ * ``has_property`` - match value of property with given name
+ * ``has_properties`` - match an object that has all of the given properties.
+ * ``has_string`` - match ``str()``
+ * ``instance_of`` - match object type
+ * ``none``, ``not_none`` - match ``None``, or not ``None``
+ * ``same_instance`` - match same object
+ * ``calling, raises`` - wrap a method call and assert that it raises an exception
+
+* Number
+
+ * ``close_to`` - match number close to a given value
+ * ``greater_than``, ``greater_than_or_equal_to``, ``less_than``,
+ ``less_than_or_equal_to`` - match numeric ordering
+
+* Text
+
+ * ``contains_string`` - match part of a string
+ * ``ends_with`` - match the end of a string
+ * ``equal_to_ignoring_case`` - match the complete string but ignore case
+ * ``equal_to_ignoring_whitespace`` - match the complete string but ignore extra whitespace
+ * ``matches_regexp`` - match a regular expression in a string
+ * ``starts_with`` - match the beginning of a string
+ * ``string_contains_in_order`` - match parts of a string, in relative order
+
+* Logical
+
+ * ``all_of`` - ``and`` together all matchers
+ * ``any_of`` - ``or`` together all matchers
+ * ``anything`` - match anything, useful in composite matchers when you don't care about a particular value
+ * ``is_not`` - negate the matcher
+
+* Sequence
+
+ * ``contains`` - exactly match the entire sequence
+ * ``contains_inanyorder`` - match the entire sequence, but in any order
+ * ``has_item`` - match if given item appears in the sequence
+ * ``has_items`` - match if all given items appear in the sequence, in any order
+ * ``is_in`` - match if item appears in the given sequence
+ * ``only_contains`` - match if sequence's items appear in given list
+ * ``empty`` - match if the sequence is empty
+
+* Dictionary
+
+ * ``has_entries`` - match dictionary with list of key-value pairs
+ * ``has_entry`` - match dictionary containing a key-value pair
+ * ``has_key`` - match dictionary with a key
+ * ``has_value`` - match dictionary with a value
+
+* Decorator
+
+ * ``calling`` - wrap a callable in a deffered object, for subsequent matching on calling behaviour
+ * ``raises`` - Ensure that a deferred callable raises as expected
+ * ``described_as`` - give the matcher a custom failure description
+ * ``is_`` - decorator to improve readability - see `Syntactic sugar` below
+
+The arguments for many of these matchers accept not just a matching value, but
+another matcher, so matchers can be composed for greater flexibility. For
+example, ``only_contains(less_than(5))`` will match any sequence where every
+item is less than 5.
+
+
+Syntactic sugar
+===============
+
+PyHamcrest strives to make your tests as readable as possible. For example, the
+``is_`` matcher is a wrapper that doesn't add any extra behavior to the
+underlying matcher. The following assertions are all equivalent:
+
+.. code:: python
+
+ assert_that(theBiscuit, equal_to(myBiscuit))
+ assert_that(theBiscuit, is_(equal_to(myBiscuit)))
+ assert_that(theBiscuit, is_(myBiscuit))
+
+The last form is allowed since ``is_(value)`` wraps most non-matcher arguments
+with ``equal_to``. But if the argument is a type, it is wrapped with
+``instance_of``, so the following are also equivalent:
+
+.. code:: python
+
+ assert_that(theBiscuit, instance_of(Biscuit))
+ assert_that(theBiscuit, is_(instance_of(Biscuit)))
+ assert_that(theBiscuit, is_(Biscuit))
+
+*Note that PyHamcrest's ``is_`` matcher is unrelated to Python's ``is``
+operator. The matcher for object identity is ``same_instance``.*
+
+
+Writing custom matchers
+=======================
+
+PyHamcrest comes bundled with lots of useful matchers, but you'll probably find
+that you need to create your own from time to time to fit your testing needs.
+This commonly occurs when you find a fragment of code that tests the same set
+of properties over and over again (and in different tests), and you want to
+bundle the fragment into a single assertion. By writing your own matcher you'll
+eliminate code duplication and make your tests more readable!
+
+Let's write our own matcher for testing if a calendar date falls on a Saturday.
+This is the test we want to write:
+
+.. code:: python
+
+ def testDateIsOnASaturday(self):
+ d = datetime.date(2008, 04, 26)
+ assert_that(d, is_(on_a_saturday()))
+
+And here's the implementation:
+
+.. code:: python
+
+ from hamcrest.core.base_matcher import BaseMatcher
+ from hamcrest.core.helpers.hasmethod import hasmethod
+
+ class IsGivenDayOfWeek(BaseMatcher):
+
+ def __init__(self, day):
+ self.day = day # Monday is 0, Sunday is 6
+
+ def _matches(self, item):
+ if not hasmethod(item, 'weekday'):
+ return False
+ return item.weekday() == self.day
+
+ def describe_to(self, description):
+ day_as_string = ['Monday', 'Tuesday', 'Wednesday', 'Thursday',
+ 'Friday', 'Saturday', 'Sunday']
+ description.append_text('calendar date falling on ') \
+ .append_text(day_as_string[self.day])
+
+ def on_a_saturday():
+ return IsGivenDayOfWeek(5)
+
+For our Matcher implementation we implement the ``_matches`` method - which
+calls the ``weekday`` method after confirming that the argument (which may not
+be a date) has such a method - and the ``describe_to`` method - which is used
+to produce a failure message when a test fails. Here's an example of how the
+failure message looks:
+
+.. code:: python
+
+ assert_that(datetime.date(2008, 04, 06), is_(on_a_saturday()))
+
+fails with the message::
+
+ AssertionError:
+ Expected: is calendar date falling on Saturday
+ got: <2008-04-06>
+
+Let's say this matcher is saved in a module named ``isgivendayofweek``. We
+could use it in our test by importing the factory function ``on_a_saturday``:
+
+.. code:: python
+
+ from hamcrest import *
+ import unittest
+ from isgivendayofweek import on_a_saturday
+
+ class DateTest(unittest.TestCase):
+ def testDateIsOnASaturday(self):
+ d = datetime.date(2008, 04, 26)
+ assert_that(d, is_(on_a_saturday()))
+
+ if __name__ == '__main__':
+ unittest.main()
+
+Even though the ``on_a_saturday`` function creates a new matcher each time it
+is called, you should not assume this is the only usage pattern for your
+matcher. Therefore you should make sure your matcher is stateless, so a single
+instance can be reused between matches.
