Run just a specific scalatest test from sbt

问题:

sbt's test-only command can be used to run the tests found in a specific test class. With JUnit tests you can use test-only to run specific methods on a test class e.g. test-only mypackage.MyTestClass.test1Equals1 to run just that method.

Is such a thing possible with scalatest's more free-form test syntax, presumably by working out the name it uses internally to reference a specific test? If it isn't possible in FreeSpec (which is easy to imagine given its nature) is there a way to do it with a simpler testing approach like FunSuite?

回答1:

For a general solution we need to wait for sbt#911, but apparently ScalaTest 2.1.3 has a support for running a specific test. Seth says:

This is now supported in ScalaTest 2.1.3 with:

test-only *MySuite -- -z foo

to run only the tests whose name includes the substring "foo". For exact match rather than substring, use -t instead of -z.

回答2:

To run a test:

sbt test-only com.path.to.UnitTestSpec

To run a particular integration test:

sbt it:test-only com.path.to.IntegrationTestSpec
