Mock data generator for swagger api
npm install swagmock-specificNote: Swagmock version 1.0.0 onwards requires Node.js v6+ ("engines": {"node": ">=6.x"}). Please use v0.0.x (say 0.0.5), if you want to run this module on any previous node.js versions.

`javascriptthenable
let Swagmock = require('swagmock');
let Mockgen = Swagmock(api, options);
// api Can be one of the following.
// 1) A relative or absolute path to the Swagger api document.
// 2) A swagger api Object.
// 3) A promise (or a ) that resolves to the swagger api Object.validated
// Set the : true in options, if the api Object is already validated`
// and dereferenced ($ref are resolved ).
Promise response:
`javascript`
let responseMock = Mockgen.responses({}); //returns a promise that resolves to response mock
responseMock.then(mock => {
//Use mock here
}).catch(error => {
Assert.ifError(error);
});
Callback style:
`javascript
Mockgen.responses({ path: '/somepath'}, (error, mock) => {
Assert.ifError(error);
//Use mock here
});
`
Check the API for more details.
Initialize the mock generator
`javascript`
const apiPath = 'http://petstore.swagger.io/v2/swagger.json';
let Assert = require('assert');
let Swagmock = require('swagmock');
let Mockgen = Swagmock(apiPath);
Response mock generation:
`javascript`
mockgen.responses({
path: '/pet/findByStatus',
operation: 'get',
response: 200
}).then(mock => {
console.log(mock); // This would print:
// {
// "responses": [{
// "id": 2530624032210944,
// "category": {
// "id": 8200505595527168,
// "name": "r($vA&"
// },
// "name": "doggie",
// "photoUrls": ["p0x1", "6O)3*kO"],
// "tags": [{
// "id": 4590764340281344,
// "name": "WCTA6f!"
// }, {
// "id": -4614156653166592,
// "name": "e"
// }],
// "status": "pending"
// }]
// }
}).catch(error => {
Assert.ifError(error);
});
Parameters mock generation:
`javascript
mockgen.parameters({
path: '/pet/findByStatus',
operation: 'get'
}).then(mock => {
console.log(mock);//This would print:
// {
// "parameters": {
// "query": [{
// "name": "status",
// "value": [ 'available', 'pending' ],
// "separator": "multi"
// }]
// }
// }
}).catch(error => {
Assert.ifError(error);
})
`
Check Examples for more details on mock generators.
You can set the following formats in your swagger parameters and responses to get a better mock data:
- date
- date-time
- uri
- url
- name
- email
- phone
- address
- boolean
- gender
- sentence
- zip
- uuid
- guid
- ipv4
- ipv6
- hostname
Swagger example:
`json`
...
"properties": {
"name": {
"type": "string",
"format": "name",
},
"email": {
"type": "string",
"format": "email",
}
}
...
Swagmock(api, [options])
api - (Object) or (String) or (Promise*) - (required) - api can be one of the following.
- A relative or absolute path to the Swagger api document.
- A URL of the Swagger api document.
- The swagger api Object
- A promise (or a thenable) that resolves to the swagger api Object
options - (Object*) - (optional) - Additional options to create the mock generator.
- validated - Set this property to true if the api is already validated against swagger schema and already dereferenced all the $ref. This is really useful to generate mocks for parsed api specs. Default value for this is false and the api will be validated using swagger-parser validate.
mockgen.responses(options, [callback])
This generates the mock response objects based on the options
options - (Object*) - (required) - Options to control the mock generation.
callback - (Function*) - (optional) - function (error, mock). If a callback is not provided a Promise will be returned.
path - (String*) - (optional) - The path for which the response mock need to be generated. For example /pet/findByStatus, /pet etc. If a path is not specified, mock response will be generated for all the paths defined by the swagger api.
operation - (String*) - (optional) - The operation for which the response mock need to be generated. For example get, post etc. If operation is not specified, mock response will be generated for all the operations defined by the swagger api.
response - (String*) - (optional) - The response for which the response mock need to be generated. For example 200, 400, default etc. If response is not specified, mock response will be generated for all the responses defined by the swagger api.
mockgen.parameters(options, [callback])
This generates the mock parameters objects based on the options
options - (Object*) - (required) - Options to control the mock generation.
callback - (Function*) - (optional) - function (error, mock). If a callback is not provided a Promise will be returned.
path - (String*) - (optional) - The path for which the parameters mock need to be generated. For example /pet/findByStatus, /pet etc. If a path is not specified, mock parameters will be generated for all the paths defined by the swagger api.
operation - (String*) - (optional) - The operation for which the parameters mock need to be generated. For example get, post etc. If operation is not specified, mock parameters will be generated for all the operations defined by the swagger api.
mockgen.requests(options, [callback])
This generates the mock request object based on the options. requests API resolves the parameters mock data to generate the request mock object useful for unit tests.
options - (Object*) - (required) - Options to control the mock generation.
callback - (Function*) - (optional) - function (error, mock). If a callback is not provided a Promise will be returned.
path - (String*) - (optional) - The path for which the parameters mock need to be generated. For example /pet/findByStatus, /pet etc. If a path is not specified, mock parameters will be generated for all the paths defined by the swagger api.
operation - (String*) - (optional) - The operation for which the parameters mock need to be generated. For example get, post etc. If operation is not specified, mock parameters will be generated for all the operations defined by the swagger api.
request Object will have following possible properties query, header, pathname, path, formData or body based on the parameters defined for the path and operation.
Mock request Path templates are resolved using path parameters.
`javascript
mockgen.requests({
path: '/pet/findByStatus',
operation: 'get'
}, function (error, mock) {
assert.ifError(error);
console.log(mock);
//This would print:
// {
// "request": {
// "query": "status=available&status=pending"
// }
// }
});
