The notes for 1.0.0.-M6 say,

org.scalajs.testinterface.TestUtils was removed (it was deprecated in 0.6.25); use scala.scalajs.reflect.Reflect or portable-scala-reflect instead.

[ashawley]

@sjrd Can you suggest a migration path here?

[sjrd]

As the release notes say, use scala.scalajs.reflect.Reflect instead. The API of Reflect is tiny; it's supposed to be straightforward. Do you need any specific guidance?

[ashawley]

@sjrd I was going to update to 1.0.0-M6, but there isn't a portable-scala-reflect artifact published for 1.0.0-M6.

[sjrd]

Since ScalaCheck already uses a JS-specific Platform.scala for reflective operations, you can directly use scala.scalajs.reflect.Reflect from there, without going through portable-scala-reflect. That will be easier.

[ashawley]

Ah, ok. This is more effort than I expected, then. I have to task switch, so I'll close to let someone else pick it up.
