If you are using Spring Boot with MongoDB, then a MongoDB connection is required even if you are unit testing a function. 
Spring creates a connection to mongoDB during start up, because of Autowired beans in your code. This slows down your unit tests, and 
also means your unit tests require access to the MongoDB server.

Here is what you need to do:
1. Mock the beans created by org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration:
    @Bean
    public MongoDbFactory mongoDbFactory(){
        return null;
    }

A Makefile for building ruby gems

This Makefile aids in developing a ruby gem. It's pretty opinionated to my workflow, but it might be useful to you, so here it goes.

1. Assumes you use of [gs][gs] (or [gst][gst]) for managing gemsets.
2. Assumes you use [dep][dep] for installing dependencies. Because fuck Bundler.
3. Assumes the directory in which the source code is located is named after the gem. So basename $(dirname $(pwd)) would return foo
