!> Implementation of the meta data for a test.
!>
!> The test data structure is effectively a decorated version of an executable
!> and shares most of its properties, except for the defaults and can be
!> handled under most circumstances just like any other executable.
!>
!> A test table can currently have the following fields
!>
!>```toml
!>[[ test ]]
!>name = "string"
!>source-dir = "path"
!>main = "file"
!>link = ["lib"]
!>[test.dependencies]
!>```
