Swagger supports response and schema examples as can be seen from their documentation on adding examples. If your API description contains response or schema examples, then the exported Swagger file will be populated with these examples.
Details
Many API description formats support response or schema examples e.g. a RAML 1.0 file can contain a schema example as follows:
Email:
type: object
properties:
subject: string
body: string
example:
subject: My Email 1
body: This is the text for email 1.
When exporting to Swagger 2.0, this example will look like:
"Email": {
"title": "Email",
"example": {
"subject": "My Email 1",
"body": "This is the text for email 1."
},
"type": "object",
"properties": {
"subject": {
"description": "",
"type": "string"
},
"body": {
"description": "",
"type": "string"
}
},
"required": [
"subject",
"body"
]
}
