Play! framework: customize which tests are run

Question

I have a Play! 2 for Scala application, and I am using Specs2 for tests. I can run all tests with the test command, or a particular specification with test-on

Answer 1

First, following the specs2 guide one must add tags to the specifications, like this

class MySpec extends Specification with Tags {
  "My spec" should {
    "exclude this test" in {
      true
    } tag ("foo")

    "include this one" in {
      true
    }
  }
}

The command line arguments to include are documented here

Then one can selectively include or exclude test with

test-only MySpec -- exclude foo
test-only MySpec -- include foo
