8 Allow intuitive and extensible framework for mocking REST calls towards VID external peers,
9 both for dev and testing purposes.

23 High-level description:
24 ************************************************************************************
26 The Simulator uses MockServer instance running "under the hood" listening to its own HTTP port.
27 the Simulator allows to register the expected request and response to the MockServer instance
28 with an exposed REST call (see details below), and all other requests are automatically redirected to MockServer.
29 If a request was properly registered, the MockServer will reply with an expected response, which will be in turn
30 returned by the Simulator to the caller.
32 The Simulator supports both dynamic and preset (static) registration, looking for JSON files in correct registration format and
33 registrating them on startup - see details below under "Preset registration"
35 Note that the behaviour is generic, and no additional code is expected to be added when there are new
36 MSO/AAI/any other component APIs to be mocked. They will just need to be properly registered using the existing API.
39 Simulator can be used in both test and dev modes. You can change the server root of any of VID external REST peers
40 to the one of the simulator (see details in "Usage"), and either register the expected request/response dynamically or preset it
41 to be loaded during startup. That's it - you're ready to use the simulator either in dev mode, or in test mode by running integration tests vs VID.
44 ***********************************************************************************
45 Simulator configuration:
46 ************************************************************************************
48 Under src/main/resources/:
50 1) simulator.properties - currently allows to configure the connection details of MockServer, preset registration mode, and other simulator-related props.
52 2) mockserver.properties - TBD (MockServer logging, SSL etc.)
55 ************************************************************************************
57 ************************************************************************************
59 If enabled in the properties, the Simulator will also run preset registration, looking for JSON files in correct registration format and
60 registrating them on startup.
62 The files must be placed under src/main/resources/preset_registration.
64 If preset registration is enabled, the simulator will run the scheduler "schedulerDetails" API registration, and any other JSON file which it will find under the folder.

83 *************************************************************************************
84 If you need dynamic registration, register API for dynamic registration:
86 POST {protocol}://{Tomcat host}:{Tomcat port}/vidSimulator/registerToVidSimulator
88 To unregister and clear *all* expectations, use DELETE action:
90 DELETE {protocol}://{Tomcat host}:{Tomcat port}/vidSimulator/registerToVidSimulator
93 ***********************************************************************************
94 Registration body JSON specification (see and copy/paste examples below):
95 ***************************************************************************************
98 "simulatorRequest" - request wrapper.
100 Note that from the below fields, it's mandatory to populate at least one.
101 No field is mandatory by itself.
103 "id" - String, will be expected as a value in an X-header with a key "x-simulator-id"
104 "method" - String, HTTP method of the request.
105 "path" - String, relative path of the request, MUST be WITH leading slash and WITHOUT trailing slash.
106 "queryParams" - Map<String, List<String>>, query params of key-->list of values.
107 "body" - String, body of the request in case of POST/PUT.
108 Note that JSON String should be properly escaped.
110 "simulatorResponse" - response wrapper.
112 Note that from the below fields, it's mandatory to populate at least "responseCode".
114 "responseCode" - integer, HTTP response code.
115 "responseHeaders" - Dictionary Object with HTTP headers and values.
116 "body" - String, body of the response.
117 Note that JSON String should be properly escaped.
118 "file" - String, a filename of the file sitting in "vid-ext-services-simulator\src\main\resources\download_files"
119 Used for simulating file download requests.
121 "misc" - optional configurations.
122 "numberOfTimes" - Integer. Limit this expectation to fire only a
123 given amount of times. Values like -1 or less are
124 treated as "unlimited". Default is unlimited.
125 "replace" - Boolean. If there is already a registered expectation with
126 same simulatorRequest, remove the old registered expectation.
127 If set to 'False' -- the result will be appended to fire
128 after the old registered expectation(s) will fulfill their
129 numberOfTimes. Default is 'True'.
131 ************************************************************************************
133 ************************************************************************************
135 1) In system.properties, change the API you want to mock - set server root to be
136 {protocol}://{Tomcat host}:{Tomcat port}/vidSimulator (for example http://localhost:7080/vidSimulator)
138 Example of mocking the scheduler:
140 scheduler.server.url=http://localhost:7080/vidSimulator/scheduler
143 2) Check the simulator.properties file under /resources to verify the desired properties of the inner MockServer instance.
144 * Default MockServer URI is http://localhost:1080
146 3) Build VID and VID Simulator WARs
148 4) Deploy the Simulator WAR under Tomcat, either same as VID or another instance.
149 * Application context path of the Simulator is /vidSimulator
