HTTP/gRPC Mocking tool

What is Camouflage?

Camouflage is a service virtualization tool inspired by namshi/mockserver. As the original description says, the mocking/service virtualization works on a file based structure where you simply organize your mocked HTTP responses in a bunch of mock files and it will serve them like they were coming from a real API; in this way you can write your frontends without caring too much whether your backend is really ready or not.

Features

• Mocking support for HTTP, HTTPS, HTTP2, gRPC and websockets. (graphql mocking support development ongoing)
• Dynamic/realistic responses without having to write any code.
• Conditional responses based on request parameters.
• Delay Simulation.
• Inbuilt monitoring.
• Inbuilt backup and restore mechanism.
• Quick start with camouflage init and camouflage restore modules.

Getting Started

1. Camouflage is an NPM package, therefore to install Camouflage, you'd need to install NodeJS (>v14) first, if you haven't already done so.
2. Install Camouflage: npm install -g camouflage-server
3. Run camouflage --version to validate the installation was successful.
4. Create an empty directory anywhere in your machine and navigate to it in your terminal.
5. Execute command camouflage init. This creates a basic skeleton of the folders you'd need in order to get started. You can modify these folders as per your requirements.
6. Start the Camouflage server by initializing it with a config.yml file: camouflage --config config.yml

Create your first mock

Camouflage follows the same convention as mockserver to create mocks. For example,

1. You start by creating a directory ${MOCKS_DIR}/hello-world
2. Create a file GET.mock under ${MOCKS_DIR}/hello-world
3. Paste following content:

HTTP/1.1 200 OK
X-Custom-Header: Custom-Value
Content-Type: application/json

{
    "greeting": "Hey! It works!"
}

Navigate to http://localhost:8080/hello-world

Building from source

Camouflage is still in its early development and has a long way to go before it reaches v1.0.0. Which means there might be some bugs, missed use cases, incorrect implementations of some functionalities. This is to be expected. But, the good news is that we are constantly evolving.

There might be times when latest changes have not gone to release yet, such changes exist in the develop branch, which is the most updated version of Camouflage. If you'd like to get your hands on the upcoming release of Camouflage at any point, you can build it from the source. However, since this source might contain changes that are not tested yet and are not ready for use, you might want to proceed with caution.

1. Clone the repository: git clone https://github.com/testinggospels/camouflage.git
2. Checkout develop branch: git checkout develop
3. Install dependencies: npm install
4. Build the project: npm build
5. At this point you can run Camouflage using: node bin/camouflage.js --config ./config.yml
6. However if you'd like to install Camouflage globally, execute: npm pack
7. Install by running command: npm install -g camouflage-server-0.0.0-development.tgz or npm install -g camouflage-server-0.0.0-development.zip
