Difference between Test and test in sbt

Question

For example i can write in my build:

name in Test := "some name"
name in test := "some name"

and both would perfectly work. So what's the difference between them?

Answer 1

In the first case Test is of type configuration. As it is sad in the official docs to sbt:

A configuration defines a flavor of build, potentially with its own classpath, sources, generated packages, etc. 

and the second test is just a simple task defined in the global scope. If you call inspect test in sbt it will show that test just executes all tests and is provided by global scope *:test , it's like an aggregator of all test tasks. The whole task tree under test you can see with inspect tree task command. To inspect Test configuration you should call inspect test:configuration , as you can see it just provides configuration for test scope in your project. So name in test and name in Test have the same result
