Across the industry, many express an interest in testing. Yet, when push comes to shove and we run into tricky situations, it's quite easy to throw up our hands and shout, This is too hard!
Spring Boot aims to help!
JUnit, all by itself, gives us the power to declare tests and assert pass/fail scenarios. But in reality, not everything works straight out of the box. For example, parts of our code will easily come to rely upon Boot autoconfiguring various beans as well as having that powerful property support.
A keen example is the need to do some MongoDB operations. It would be quite handy if we could ask Spring Boot to autoconfigure just enough beans to support MongoDB for our tests but nothing else.
Well, today's our lucky day.
Spring Boot 1.5 introduced slice testing. This is where a subset of Spring Boot's autoconfiguration power can be switched...
