SBT setup

You can enable snapshot4s for a variety of SBT project layouts.

• For single project SBT builds follow these instructions.
• For multi-project SBT builds follow these instructions
• For sbt-projectmatrix follow these instructions.
• For sbt-crossproject and sbt-typelevel follow these instructions.

Single project builds

For single project builds, follow the quick start.

Multi-project builds

If you have a multi-project setup, you must enable the plugin in each project containing snapshot tests.

Add the plugin to plugins.sbt.

addSbtPlugin("com.siriusxm" % "sbt-snapshot4s" % "0.1.6")

Enable it for each project in build.sbt.

val core = (project in file("core")).enablePlugins(Snapshot4sPlugin)

val utils = (project in file("utils")).enablePlugins(Snapshot4sPlugin)

val root = (project in file(".")).aggregate(core, utils)

Finally, add the integration library for your test framework.

sbt-projectmatrix

If you use sbt-projectmatrix, you can enable the plugin for a matrix.

Add the plugin to plugins.sbt.

addSbtPlugin("com.siriusxm" % "sbt-snapshot4s" % "0.1.6")

Enable it for each matrix in build.sbt.

val core = (projectMatrix in file("core")).enablePlugins(Snapshot4sPlugin)

Finally, add the integration library for your test framework.

sbt-crossproject and sbt-typelevel

You can enable the plugin for all cross types, for both JVM and JS.

Add the plugin to plugins.sbt.

addSbtPlugin("com.siriusxm" % "sbt-snapshot4s" % "0.1.6")

Enable the plugin.

val core = crossProject(JVMPlatform, JSPlatform)
  .crossType(CrossType.Dummy)
  .in(file("core"))
  .enablePlugins(Snapshot4sPlugin)

If you use the Pure or Full cross types, set the snapshot4sResourceDirectory to the shared test resource directory.

val core = crossProject(JVMPlatform)
  .crossType(CrossType.Pure)
  .in(file("core"))
  .settings(
    snapshot4sResourceDirectory := CrossType.Pure
      .sharedResourcesDir(baseDirectory.value, "test")
      .get / "snapshot",
  )
  .enablePlugins(Snapshot4sPlugin)

Finally, add the integration library for your test framework.
