# Zombie

## How to run application

```bash
docker-compose run app
```

Or if you have `Go` v1.13 installed locally, then run

```bash
go run cmd/main.go
```

## How to run tests

```bash
docker-compose run app go test ./... -cover
```

## Where to start to read the code

Please read the code from the entry point `cmd/main.go`

### How to application works

* Load input to initialise the application, it will set up the `grid`, `zombie`, `creatures` and `commands`
* Make the zombie to start moving, as well as the transformed zombies. 
* Print out the result.

## Assumptions

* All the input data is valid


## Highlights

* Used `TableDrivenTests`
* Used `interface` and `map` to model the `command` part to avoid `if else` checks
* Built a `First-In-First-Out` structure `nextZombie` in `application` to represent the next zombie to run.     
* Had `docker compose` built in, you don't need to have Go installed locally. One command to bring up the whole application.
