Moxy

Moxy is a simple mocker and proxy application server. Here you can create mock endpoints as well as proxy requests in case no mock exists for the endpoint.

How it works

Features

Small, Pragmatic and Easy to Use

Dockerized
Compiled
Easily configurable via Environment Variables
Self-contained, does not require Go or any other dependency, just run the binary or the container

File-based Persistence

No heavy database involved.
Saves the mock endpoints in files.

Security

TLS can be enabled by providing your own SSL/TLS Certificates.

Reliability

Uses Go Actuator
Fully Tested, Unit, Functional & Linted & 0 Race Conditions Detected.

Customizations

Mock endpoints created are highly customizable.
Application port can be configured via the environment variable.
Database file path can be configured via the environment variable.

Project Versioning

Moxy uses semantic versioning. No API changes will be introduced in the minor and patch version changes. New minor versions might add additional features to the API.

Getting Started(standalone application)

You can download a pre-compiled package for Linux or MAC OSX here.

You can also pull the latest docker image for Moxy from Docker Hub.

docker pull ghcr.io/sinhashubham95/moxy:latest

Create an empty directory, change into it and run the following to start Moxy:

docker run --rm --user $(id -u):$(id -g) -v $PWD:/data -p 9091:9091 sinhashubham95/moxy -host 0.0.0.0

The container will have access to the current local directory and all sub-folders.

Usage

Mock - POST /moxy/mock

This is used to create a new mock endpoint. Each mock endpoint created can be tagged, which means you can create multiple mocks for the same endpoint.

POST /moxy/mock

{
    "tag": "",
    "method": "",
    "path": "",
    "responseDelayInMillis": 0,
    "responseStatus": 0,
    "responseBody": {}
}

Tag: This is used to tag the created mock endpoint. It is used to set the context for this endpoint. You can have many instances of the same endpoint.
Method: This is the request method for this endpoint. It can either be GET, POST, PUT or DELETE.
Path: This is the request path for this endpoint. Note that the request path should not start with either /actuator or /moxy.
Response Delay In Millis: This is the delay added before actually returned the mocked response. Note that this delay is over and above the delay added over the network. In other words, this is the server side delay. It can be useful in testing the resiliency of the applications using this endpoint and testing the timeout functionality.
Response Status: This is the status code for the mocked response. It should be in the range of a valid HTTP status code which is >=100 and <= 599.
Response Body: This is the response body for the mocked response. If it is a JSON, it can be provided as a JSON body itself, but anything apart from JSON has to be converted to a string and sent. Don't worry the mocked response will be returned with the correct type, that will be taken care of automatically.

Remove Mock - DELETE /moxy/unMock

This is used to remove the existing mock endpoint.

DELETE /moxy/unMock

{
    "tag": "",
    "method": "",
    "path": ""
}

Tag: This is used to tag the created mock endpoint. It is used to set the context for this endpoint. You can have many instances of the same endpoint.
Method: This is the request method for this endpoint. It can either be GET, POST, PUT or DELETE.
Path: This is the request path for this endpoint. Note that the request path should not start with either /actuator or /moxy.

Calling any Endpoint

This is used to call any endpoint. If any mock exists for that endpoint, then the mocked response will be returned, otherwise the actual endpoint will be called.

The following 2 mandatory headers should be passed with any such request.

Tag(X-Tag): This is the tag used while creating the mock endpoint, to query the mock for the current context.
Actual Base Url(X-Url): This is the actual url that will be used to call the actual endpoint, or basically proxy to the actual server, in case no mock exists.

Example(Using the following actual endpoint - https://www.google.co.in/imghp)

Create a mock endpoint as follows.

POST /moxy/mock

{
    "tag": "1234",
    "method": "GET",
    "path": "/imghp",
    "responseDelayInMillis": 200,
    "responseStatus": 200,
    "responseBody": {
        "naruto": "rocks"
    }
}

Create another mock endpoint with the same request method and path but a different context(tag).

POST /moxy/mock

{
    "tag": "5678",
    "method": "GET",
    "path": "/imghp",
    "responseDelayInMillis": 200,
    "responseStatus": 200,
    "responseBody": "naruto always rocks"
}

Try calling this endpoint with the first tag.

GET /naruto

X-Tag 1234
X-Url https://www.google.co.in

You will get the following response.

{
  "naruto": "rocks"
}

Now if you call this with the second tag.

GET /naruto

X-Tag 5678
X-Url https://www.google.co.in

You will get the following response.

naruto always rocks

Now try deleting the mock for the first tag.

DELETE /moxy/unMock

{
    "tag": "1234",
    "method": "GET",
    "path": "/imghp"
}

Now again try calling the endpoint with the first tag.

GET /naruto

X-Tag 1234
X-Url https://www.google.co.in

The actual endpoint will be called, and the following response you could see.
