Known limitations

This page is a shortlist of the known limitations of snapshot4s. If you encounter any issues not listed below, we encourage you to report them.

Scala Native is not supported​

snapshot4s doesn't yet support Scala Native.

snapshot4s uses pprint to efficiently generate the source code corresponding to an expected value. This doesn’t add import statements for enum and classes within objects. You may need to add an import statement corresponding to the enum or object in question.

snapshot4s doesn't depend on a formatter, so can’t format its generated code. If you'd like to run scalafmt automatically after promoting your snapshots, you can redefine snapshot4sPromote in your build.sbt:

val root = (project in file("."))
  .settings(
    snapshot4sPromote := {
      snapshot4sPromote.value
      (Test / scalafmt).value
    })
  .enablePlugins(Snapshot4sPlugin)
