regurgitator-extensions-yml

regurgitator is a lightweight, modular, extendable java framework that you configure to ‘regurgitate’ canned or clever responses to incoming requests; useful for quickly mocking or prototyping services without writing any code. simply configure, deploy and run.

extension steps in yml

json-parameter

a json-parameter creates a parameter, extracting its value from within a json document, using json-path:

json-parameter:
 name: book-name
 source: book-catalogue
 json-path: $.catalogue.book.name

xml-parameter

an xml-parameter creates a parameter, extracting its value from within an xml document, using xpath:

xml-parameter:
 name: book-name
 source: book-catalogue
 xpath: /bk:catalogue/bk:book/bk:name
  namespaces:
   bk: http://books.com

extension constructs in yml

freemarker-builder

a freemarker-builder aggregates parameter values together using a freemarker template.

freemarker-builder:
 source: template-param
freemarker-builder:
 file: classpath:/template.ftl
freemarker-builder:
 value: This is a ${descriptive} day

a freemarker-builder can use the same value source properties as other steps, such as create-parameter, getting its template text from a source parameter, a file or an explicit value.

a freemarker-builder builds from just the parameters context by default. if the all-contexts property is true, all context data is made available to the builder, with dashes replaced by underscores in context names, and the colon separating context and parameter names replaced with a period, e.g. request-metadata:method becomes request_metadata.method when referenced in the template.

freemarker-builder:
 all-contexts: true
 value: <response><payload>${response_payload.text}</payload><status-code>${response_metadata.status_code}</status-code><content-type>${response_metadata.content_type}</content-type></response>

json-path-processor

a json-path-processor processes a parameter value, extracting a value from it using json path.

create-parameter:
 name: book-name
 source: book-catalogue
 processor:
  json-path-processor:
   json-path: $.catalogue.book.name

xpath-processor

an xpath-processor processes a parameter value, extracting a value from it using xpath.

create-parameter:
 name: book-name
 source: book-catalogue
 processor:
  xpath-processor:
   xpath: /cat:atalogue/bk:book/@name
   namespaces: cat=http://catalogues.com,bk=http://books.com

namespaces for an xpath-processor can also be declared as an object property of the processor:

create-parameter:
 name: book-name
 source: book-catalogue
 processor:
  xpath-processor:
   xpath: /cat:atalogue/bk:book/@name
   namespaces:
    cat: http://catalogues.com
    bk: http://books.com

freemarker-processor

a freemarker-processor processes a parameter value, formatting the value using a freemarker template.

create-response:
 source: unformatted-response
 processor:
  freemarker-processor:
   file: classpath:/template.ftl
create-response:
 source: unformatted-response
 processor:
  freemarker-processor:
   value: The response was: ${value}

the parameter value is made available to the template as simply value. the template text can be specified in a value property or drawn in from a file.

json-schema-validator

a json-schema-validator is a value-processor that validates a parameter value against a json schema file.

create-response:
 source: response
 processor:
  xml-schema-validator:
   file: classpath:/response_schema.json

validating a parameter value can be useful in ensuring that your configured logic and processing always returns valid responses. if the value fails validation, an exception is thrown; if it passes, the value is passed through unchanged.

xml-schema-validator

an xml-schema-validator is a value-processor that validates a parameter value against an xml schema file.

create-response:
 source: response
 processor:
  xml-schema-validator:
   file: classpath:/response_schema.xsd

validating a parameter value can be useful in ensuring that your configured logic and processing always returns valid responses. if the value fails validation, an exception is thrown; if it passes, the value is passed through unchanged.

contains-json-path

a contains-json-path is a condition-behaviour that checks whether a parameter’s contents contains a sub-value that can be extracted using an json-path expression. if a sub-value can be extracted from the starting value using the json-path expression provided then the condition passes.

...
conditions:
  - source: parameters:json
    contains-json-path: $.catalog.book.name
...
...
conditions:
  - source: parameters:json
    value: $.catalog.book.name
    behaviour: contains-json-path
...

the examples above show both ways in which the contains-json-path condition-behaviour can be used, either in the short form of "behaviour-name" : "value" or with separate value and behaviour attributes.

contains-xpath

a contains-xpath is a condition-behaviour that checks whether a parameter’s contents contains a sub-value that can be extracted using an xpath expression. if a sub-value can be extracted from the starting value using the xpath expression provided then the condition passes.

...
    conditions: 
    - source: parameters:xml
      contains-xpath: /catalog/book/@name
...
...
    conditions:
    - source: parameters:xml
      value: /catalog/book/@name
      behaviour: contains-xpath 
...
...
    conditions:
    - source: parameters:xml
      value: /catalog/book/@name
      behaviour: 
        contains-xpath:
          namespaces: cat=http://catalog.com,book=http://book.com
...
...
    conditions:
    - source: parameters:xml
      value: /catalog/book/@name
      behaviour: 
        contains-xpath:
          namespaces: 
            cat: http://catalog.com
            book: http://book.com
...

the examples above shows 3 ways in which the contains-xpath condition-behaviour can be used: in the short form of "behaviour-name" : "value"; with separate value and behaviour attributes; or with a child object. When using a child object, you can either specify namespaces for the xpath expression using a namespaces attribute, or a namespaces object.

meets-json-schema

a meets-json-schema is a condition-behaviour that checks whether a parameters’ content passes validation against a json schema.

...
    conditions: 
    - source: parameters:json
      meets-json-schema: classpath:/schema.json
...
...
conditions:
  - source: parameters:json
    value: classpath:/schema.json
    behaviour: meets-json-schema
...

the examples above show both ways in which the meets-json-schema condition-behaviour can be used, either in the short form of "behaviour-name" : "value" or with separate value and behaviour attributes.

meets-xml-schema

a meets-xml-schema is a condition-behaviour that checks whether a parameters’ content passes validation against an xml schema.

...
    conditions: 
    - source: parameters:xml
      meets-xml-schema: classpath:/schema.xsd
...
...
conditions:
  - source: parameters:xml
    value: classpath:/schema.xsd
    behaviour: meets-xml-schema
...

the examples above show both ways in which the meets-xml-schema condition-behaviour can be used, either in the short form of "behaviour-name" : "value" or with separate value and behaviour attributes.
