DoNotDiscover

Annotation used to indicate that an otherwise discoverable test class should not be discovered.

Note: This is actually an annotation defined in Java, not a Scala trait. It must be defined in Java instead of Scala so it will be accessible at runtime. It has been inserted into Scaladoc by pretending it is a trait.

ScalaTest will discover any class that either extends Suite and has a public, no-arg constructor, or is annotated with a valid WrapWith annotation. If you wish to prevent a class from being discovered, simply annotated it with DoNotDiscover, like this:

import org.scalatest._
@DoNotDiscover
class SetSpec extends FlatSpec {
  "An empty Set" should "have size 0" in {
    assert(Set.empty.size === 0)
  }
  it should "produce NoSuchElementException when head is invoked" in {
    intercept[NoSuchElementException] {
      Set.empty.head
    }
  }
}

ScalaTest will run classes annotated with DoNotDiscover if asked to explicitly, it just won't discover them.
