How to pass arguments to ScalaTest runner in Eclipse?

[patrick...@gmail.com]

I'm using ScalaTest with the ScalaTest Eclipse plugin in ScalaIde in Eclipse, and I'd like to use tags for my tests. In the docs for ScalaTest tags (http://doc.scalatest.org/3.0.1/#org.scalatest.Tag), it says that after you've set up the tags:

"When you run ScalaTest and want to either include or exclude DbTests (for example), you'd give the fully qualified name of the tag annotation (which is also the name passed to the corresponding Tag constructor) to Runner"

But I'm not invoking the runner from the command line or via the Scala "run" method - I'm using the @RunWith annotation ie - "@RunWith(classOf[JUnitRunner])". What's the best way for me to pass tags to the runner?

Hi Patrick,

I think if you are using JUnitRunner you might be out of luck.
Essentially JUnitRunner delegates the running to JUnit, and we don't
do anything with the tags. It may be that we could try and use a JUnit
Filter to filter out tests, but currently we don't:

Thank you Bill.  Wow that was a really fast response!

I don't have any reason to use the JUnit runner except that was how I learned to set up ScalaTest when I first started with it, and I wanted to stick with something that was working unless there's an advantage to changing it.  Looks like now I have a reason to change.
