GO REST ASSURED - CMD

Go Rest Assured can be used from the command line to spin up a mock rest api. The rest assured application will take in some arguments to configure configure a server to mock rest calls.

Running

1. go get github.com/jesse0michael/go-rest-assured/cmd/go-assured

Usage of go-assured:
  -host string
        a host to use in the client's url. (default "localhost")
  -port int
        a port to listen on. default automatically assigns a port.
  -preload string
        a file to parse preloaded calls from.
  -tlsCert string
        location of tls cert for serving https traffic. tlsKey also required, if specified.
  -tlsKey string
        location of tls key for serving https traffic. tlsCert also required, if specified
  -track
        a flag to enable the storing of calls made to the service. (default true)

To load in a default set of stubbed endpoints from a file, follow the Preload API Reference guide.

You can specify a TLS cert/key to mock out HTTPS traffic using mkcert self signed certs and mock HTTPS traffic.

Stubbing

To stub out an assured call hit the following endpoint /given/{path:.*}

The HTTP Method you use will be stored in the Assured Call unless you specify a "Assured-Method": "[a-zA-Z]+" HTTP Header.

The Request Body, if present, will be stored in the Assured Call

The stored Status Code will be 200 OK unless you specify a "Assured-Status": "[0-9]+" HTTP Header

You can also set a response delay with the HTTP Header Assured-Delay with a number of seconds

If your stubbed endpoint needs to return a different call on a subsequent request, then try stubbing that Method/Path again. The first time you intercept that endpoint the first call will be returned and then moved to the end of the list.

Intercepting

To use your assured calls hit the following endpoint with the Method/Path that was used to stub the call /when/{path:.*}

Go-Rest-Assured will return 404 NotFound error response when a matching stub isn't found

As requests come in, the will be stored

Callbacks

To include callbacks from Go-Rest-Assured when a stubbed endpoint is hit, create them by hitting the endpoint /callbacks To create a callbacks you must include the HTTP header Assured-Callback-Target with the specified endpoint you want your callbacks to be sent to You must also include the HTTP header Assured-Callback-Key with a key with the call to the /callbacks endpoint as well as the /given/{path:.*} endpoint that for the stubbed call you want the callback to be associated with You can also set a callback delay with the HTTP Header Assured-Callback-Delay with a number of seconds

Verifying

To verify the calls made against your go-rest-assured service, use the endpoint /verify/{path:.*}

This endpoint returns a list of assured calls made against the matching Method/Path

[
  {
    "path": "test/assured",
    "method": "GET",
    "status_code": 200,
    "delay": 0,
    "response": "eyJhc3N1cmVkIjogdHJ1ZX0=",
    "headers": {
      "Content-Length": "17",
      "User-Agent": "Go-http-client/1.1",
    },
    "query": {
      "assured": "max"
    }
  },
  {
    "path": "test/assured",
    "method": "GET",
    "status_code": 409,

    "headers": {
      "Content-Length": "5",
      "User-Agent": "Go-http-client/1.1",
    }
  }
]

Clearing

To clear out the stubbed and made calls for a specific Method/Path, use the endpoint DELETE /clear/{path:.*} Including the HTTP Header Assured-Callback-Key will clear all callbacks associated with that key (independent of path)

To clear out all stubbed calls on the server, use the endpoint /clear
