Companion object to class Specs that offers an apply factory method
for creating a Specs instance.
One use case for this object is to run multiple specification-style suites in the Scala interpreter, like this:
scala> Specs(new MyFirstSpec, new MyNextSpec).execute()
Specs has been deprecated and will be removed in a future version of ScalaTest. Please use Suites instead.
Factory method for creating a Suites instance.
