Unit test

For more details, look at the full example from test file.

Assuming you're using a module-compatible system (like webpack), start MockRestServer on top of your unit test file:

import MockRestServer from 'mock-rest-server'
 
describe('MockRestServer', function () {
  it('Start server', async () => {
    const server = await MockRestServer.start(3000, true, 0)
    server.populate('articles', 30, {
      title: String,
      body: String,
      userId: Number,
      created: Date,
      private: Boolean
    })
 
    // ...
    // ...
    // ...
 
    // don't forget to stop!
    // If you work with `--watch` param that reload your unit test, don't forget to stop server at the end of your tests.
    // It'll try to launch server again when refresh, and port will already in use.
    await server.stop()
  })
})

MockRestServer come with (optional) awesome feature that fill database with random typed data: populate(collection, length, schema)

Param name	Description	Type
collection	Collection name to create/populate	String
length	Number of resource to create in collection	Number
schema	Object send to create a resource. Values are replaced by random value based on JS type String, Number, Date or Boolean.	Object

Example

Start MockRestServer, open a new shell and run some curl on api /v1/:

curl -X POST -d '{"title":"Awesome news!","body":"Some content."}' http://localhost:3000/v1/articles
# {"title":"Awesome news!","body":"Some content.","id":1} 

Now, get your articles with:

curl http://localhost:3000/v1/articles
# [{"title":"Awesome news!","body":"Some content.","id":1},{"title":"Awesome news!","body":"Some content.","id":2}] 
curl http://localhost:3000/v1/articles/1
# {"title":"Awesome news!","body":"Some content.","id":1} 

Use api /v[xxx]/ to mock HTTP status codes (403, 404, 500...) from server response:

curl http://localhost:3000/v403/articles
