Scala and Mockito: keyword “then” is deprecated

Question

Future versions of Scala may use then as a keyword, as stated in SIP-12 .

The compiler already shows a warning for it:

Usage of then as identifier is deprecated. It can be used as a keyword in future versions of scala. Word then is reserved as a possible keyword in future versions of scala. It's usage as identifier is deprecated. See SIP-12.

I'm using Mockito and have many occurrences of then methods called.

BDDMockito.then(entityService).should(Mockito.times(2)).findBy(any)

Does anyone know if there's an alternative to replace it?

Answer 1

In scala, wrapping any identifier in backticks "`" prevents it from being treated as a keyword.

BDDMockito.`then`(entityService).should(Mockito.times(2)).findBy(any)

This has most commonly been used to allow fields/variables/methods to be named type , but it should work for then as well. It's also sometimes used to embed spaces into identifiers.

case class Bar(`class`: Int, `type`: String) {
  def `class with type`: String = s"${`class`}_${`type`}"
}

Bar(42, "skidoo").`class with type` == "42_skidoo"

Answer 2

Have you tried mockito-scala ? its API is tailored for Scala and it caters for all the language features that the Java version doesn't
