Assertion Chaining
==================

Assertions can be combined with chaining options ``and`` and ``or``. In
the following assertion payload, we’re extending the assertion we tried
previously, asserting that our endpoint was called with the
``{"foo":"bar"}`` JSON payload.

.. code:: json

   {
     "route": "hello/world",
     "assert": {
       "type": "method_match",
       "value": "post",
       "and": {
         "type": "json_body_match",
         "key_values": {
           "foo": "bar"
         }
       }
     }
   }

In plain-english: assert that ``hello/world`` was requested with the
``POST`` method, **and** the ``{"foo":"bar"}`` JSON payload.

``or`` can also be used for chaining assertions.

As shown in the example, chaining options are nested within a parent
assertion. There’s no limit to how many assertion chains you can make:

.. code:: json

   {
     "route": "hello/world",
     "assert": {
       "type": "...",
       "value": "...",
       "and": {
         "type": "...",
         "value": "...",
         "and": {
           "type": "...",
           "value": "...",
           "or": {
             "type": "...",
             "value": "...",
             "and": {
               "type": "...",
               "value": "..."
             }
           }
         }
       }
     }
   }
