Mock Data Adapter

The VoltMX Mock Data adapter capability helps you to continue to develop apps when the back-end services that an app connects to are not ready to be leveraged.

There are several instances in an app development life-cycle when back-end systems and app development happen in parallel and only the contract or interface for the app to communicate to a backend is finalized. In this scenario, you can create a response template to stub the response that is expected from the actual backend. The response template can have hard-coded values or use pre-built functions such as concat, firstName, lastName, gender, random, email, and phone, and options to randomize the output within the required criteria.

For example, in the scenario mentioned earlier, a Volt MX app developer can create the service based on a stub template. The stub response template can be set for each operation of a service. The app developers can continue to develop apps based on a sample back-end response from the stub template.

Important: Services built with Mock Data adapter will always give you mock data and cannot be switch between live backend and mock data like Stub backend response feature.

Configure Mock Data Adapter

To configure your Mock Data Adapter, provide the following details:

1. In the Name field, provide a unique name for your service.

2. From the Service Type list, select Mock Data.

   

3. For additional configuration of your service definition, provide the following details in the Advanced section:

Field	Description
Custom Code	Custom Code enables you to specify dependent JAR. To specify dependent JAR, select the JAR containing preprocessor or postprocessor libraries from the drop-down list, or click Upload New to browse the JAR file from your local system. This step allows you to further filter the data sent to the back end. Important: Make sure that you upload a custom JAR file that is built on the same JDK version used for installing Volt MX Foundry Integration. For example, if the JDK version on the machine where Volt MX Foundry Integration is installed is 1.6, you must use the same JDK version to build your custom jar files. If the JDK version is different, an unsupported class version error will appear when a service is used from a device. You can download the uploaded jars to your local system.
Throttling	API throttling enables you to limit the number of request calls within a minute. If an API exceeds the throttling limit, it will not return the service response. 1. To specify throttling in Volt MX Foundry Console, follow these steps: i. In the Total Rate Limit text box, enter a required value. With this value, you can limit the number of requests configured in your Volt MX Foundry console in terms of Total Rate Limit. ii. In the Rate Limit Per IP text box, enter a required value. With this value, you can limit the number of IP address requests configured in your Volt MX Foundry console in terms of Per IP Rate Limit. 2. To override throttling in App Services Console, refer to Override API Throttling Configuration.

Note: All options in the Advanced section are optional.

1. In the Description field, provide a suitable description for the service.

2. Click Save to save your service definition.

Create Operations for Mock Data

The Operations List tab appears only after the service definition is saved.

Note: Click Operations List tab > Configure Operation. The Configured Operations list appears.

To create an operation, follow these steps:

Authenticated App User – It restricts the access to clients who have successfully authenticated using an Identity Service associated with the app. ii. Anonymous App User – It allows the access from trusted clients that have the required App Key and App Secret. Authentication through an Identity Service is not required. iii. Public – It allows any client to invoke this operation without any authentication. This setting does not provide any security to invoke this operation and you should avoid this authentication type if possible. iv. Private - It blocks the access to this operation from any external client. It allows invocation either from an Orchestration/Object Service, or from the custom code in the same run-time environment.

1. Configure your Mock data template in the Mock Data JSON Template text field. By default this field is enabled with a sample mock response template.

Five different options are available in Volt MX Foundry under Request Input > Headers > VALUE during configuration of any operation. When you start editing this field, dependent identity services are auto populated. These options primarily determine the source of the value of the header.Request: If this option is selected, the Integration Server picks the value pairs from the client's request during run time and forwards the same to the back-end.User has the option to configure the default value. This default value is taken if the request does not have the header.Session: If this option is selected, the value of header is picked from session context based on the user configuration.Constant: Constant is used to configure the value that is picked and sent to back-end by the Integration Server during the run-time.Expression: Select this option to configure the velocity template expressions for the header values.You cannot edit the default value for expression.Identity: If this is selected, you can filter the request parameters based on the response from the identity provider. For more details to configure identity filters, refer to Enhanced Identity Filters - Integration Services.> Note: If the header value is scoped as a Request (or) Session and the same header is accessed under the Expression header value, then the expression must be represented as $request.header (or) $session.header.Example: If a header 1 value is a request and header 2 value is an expression, then the value of the expression must be $Request.header1.
      TEST VALUE	Enter a value. A test value is used for testing the service.
      DEFAULT VALUE	Enter the value, if required. The default value will be used if the test value is empty.

Advanced Parameters in Mock Data

How to Configure a Request Input and Request Header Parameters in Mock Data

You can access input parameters in a Stub template by using the { {requestBody("<request_param_name>")} } function. Additionally, you can access headers by using the { {requestHeader("<header_name>")} } function.

For example, you want to send the testUser request input parameter to the Stub template and the value of the parameter is defined in the Input Parameters section of Console. You can access the input parameter in the stub template as "inputtest": "{ {requestBody("testUser")} }".

The following sample Stub template has been configured with the testUser request input parameter.

 [
  '{ {repeat(30,40)} }',
  {
    "locationID": "{ {index()} }",
    "company": "{ {toUpperCase(company())} }",
    "phone": "+1 { {phone()} }",
    "address": "{ {integer(100, 999)} } { {street()} }, { {city()} }, { {state()} }, { {integer(100, 10000)} }",  
   ``"`inputtest": "{ {requestBody("testUser")} }"`,``
    "latitude": "{ {float(-90.000001, 90)} }",  
    "longitude": "{ {float(-180.000001, 180)} }",
    "office":"{ {random("HR Head Office","Sales Head Office","Marketing Head Office","Development Center")} }"
  }
]

Note: Volt MX functions for request input and header are as follows:

-  To access any header with name, requestHeader: Syntax: { {requestHeader("<header_name>")} }
-  To access a request parameter, requestBody: Syntax: { {requestBody("<request_param_name>")} }

##Escape braces

Description	If you want to escape braces from within a function use a single escape character as seen in the example below:
Syntax	"{ {concat("\{", "test", "\}")} }

##Nesting functions

Description	Mock Data service supports nesting functions as well. For example, if you wanted to create results that looked like dollar amounts, you can do the following:
Syntax	"{ {concat("$",float(0.90310, 5.3421, "%.2f"))} } or something like this if you wanted a capitalized F or M: { {toUpperCase(substring(gender(),0,1))} }
