+title: Muck acceptance tests
+author: Lars Wirzenius / The Ick project
+...
+
+Introduction
+=============================================================================
+
+Muck is a persistent in-memory JSON store with an HTTP API and
+advanced access control using signed JWT access tokens. This document
+presents its automated acceptance tests, using a (for now
+hypothetical) language similar to the Gherkin langauge implemented by
+Cucumber.
+
+A happy path scenario
+=============================================================================
+
+This scenario does some basic resource management via the Muck API.
+
+Start Muck. This also sets up access to it for the user by getting an
+access token, which will be used for all requests.
+
+> **given** a running Muck
+
+Check server status.
+
+> **given** I am _tomjon_  
+> **when** I make request _GET /status_  
+> **then** status code is _200_  
+> **and** response body is `{"resources":0}`
+
+Create a simple resource. Remember its id.
+
+> **when** I make request _POST /res_ with body `{"foo":"bar"}`  
+> **then** status code is _201_  
+> **and** response has header _"Muck-Owner: tomjon"_  
+> **and** resource id is remembered as _ID_  
+> **and** resource revision is remembered as _REV1_  
+>
+> **when** I make request _GET /status_  
+> **then** status code is _200_  
+> **and** response body is `{"resources":1}`
+
+Retrieve the resource.
+
+> **when** I make request _GET /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _200_  
+> **and** response body is `{ "foo": "bar" }`  
+> **and** response has header _"Muck-Id: ${ID}"_  
+> **and** response has header _"Muck-Revision: ${REV1}"_  
+> **and** response has header _"Muck-Owner: tomjon"_
+
+Make sure another user can't retreive, update, or delete the resource.
+
+> **given** I am _verence_  
+> **when** I make request _GET /res with header "Muck-Id: ${ID}"_  
+> **then** status code is _404_
+>
+> **when** I make request _PUT /res_  
+>  with header _"Muck-Id: ${ID}"_ and  
+>  header _"Muck-Revision: ${REV1}"_ and  
+>  body `{"foo": "foobar"}`
+>
+> **then** status code is _404_
+>
+> **when** I make request _DELETE /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _404_
+
+Update the resource.
+
+> **given** I am _tomjon_  
+> **when** I make request _PUT /res_ with header _"Muck-Id: ${ID}"_ and  
+>  header _"Muck-Revision: wrong"_ and  
+>  body `{"foo": "foobar"}`  
+> **then** status code is _400_
+>
+> **when** I make request _PUT /res_ with header _"Muck-Id: ${ID}"_ and  
+>  header _"Muck-Revision: ${REV1}"_ and  
+>  body `{"foo": "foobar"}`  
+> **then** status code is _200_  
+> **and** resource revision is remembered as _REV2_
+
+Check the resource has been updated.
+
+> **when** I make request _GET /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _200_  
+> **and** response body is `{"foo": "foobar"}`  
+> **and** response has header _"Muck-Id: ${ID}"_  
+> **and** response has header _"Muck-Revision: ${REV2}"_  
+> **and** response has header _"Muck-Owner: tomjon"_
+
+Restart Muck. The resource should still exist.
+
+> **when** Muck is restarted  
+> **and** I make request _GET /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _200_  
+> **and** response body is `{"foo":"foobar"}`  
+> **and** response has header _"Muck-Id: ${ID}"_  
+> **and** response has header _"Muck-Revision: ${REV2}"_  
+> **and** response has header _"Muck-Owner: tomjon"_
+
+Search for the resource. First with a condition that is no longer
+true.
+
+> **when** I make request _GET /search_ with body  
+>  `{"cond": [{"where": "data", "field": "foo", "pattern": "bar","op": "=="}]}`  
+> **then** status code is _200_  
+> **and** response body is _{"resources": []}_
+
+Now search for the correct value.
+
+> **when** user _tomjon_ makes request _GET /search_ with body  
+>  `{"cond": [{"where":"data","field":"foo","pattern":"foobar","op":"=="}]}`  
+> **then** status code is _200_  
+> **and** response body is `{"resources": ["${ID}"]}`
+
+Delete the resource.
+
+> **when** user _tomjon_ makes request _DELETE /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _200_  
+>
+> **when** user _tomjon_ makes request _GET /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _404_
+
+Restart Muck again. The resource should not exist.
+
+> **when** Muck is restarted  
+> **and** user _tomjon_ makes request _GET /res_ with header _"Muck-Id: ${ID}"_  
+> **then** status code is _404_
+
+All done.
