scalatest/scalatest

Hi all. I'm trying to write a set of tests that are not run by default but can be run when desired. I've created a custom config (and looked at everything I can find on this problem on Google) that allows me to select or disselect tests with the tag IELE but I'm still running into an issue. This is my SBT project definition:

val node = {
  val node = project
    .in(file("node/instance"))
    .dependsOn(
      ...
    )
    .settings(commonSettings("node"): _*)
    .settings(
      libraryDependencies ++= ...
    )
    .settings(
      buildInfoKeys := BuildInfoKey.ofN(
        name,
        version,
        scalaVersion,
        sbtVersion,
        gitHeadCommit,
        gitCurrentBranch,
        gitCurrentTags,
        gitDescribedVersion,
        gitUncommittedChanges,
        libraryDependencies in Compile
      ),
      buildInfoPackage := "...",
      buildInfoObject := "NodeBuildInfo",
      buildInfoOptions in Compile += BuildInfoOption.ToMap
    )
    .settings(
      (soliditySources in Compile) ++= Seq(
        baseDirectory.value / "src" / "evmTest" / "resources" / "solidity",
        baseDirectory.value / "src" / "test" / "resources" / "solidity",
        baseDirectory.value / "src" / "precompiledContracts" / "resources" / "solidity"
      )
    )
    .settings(
      executableScriptName := name.value,
      mainClass in Compile := Some("io.iohk.ethereum.App"),
      discoveredMainClasses in Compile := Seq(),
      // Requires the 'ant-javafx.jar' that comes with Oracle JDK
      // Enables creating an executable with the configuration files, has to be run on the OS corresponding to the desired version
      jdkPackagerType := "image",
      mappings in Universal += (resourceDirectory in Compile).value / "blockchain" / "development-genesis.json" -> "conf/development-genesis.json",
      mappings in Universal += (resourceDirectory in Compile).value / "logback.xml" -> "conf/logback.xml"
    )

  val Integration = config("it") extend Test
  scalastyleSources in Test ++= { (unmanagedSourceDirectories in Integration).value }
  val Benchmarks = config("benchmarks") extend Test
  val EvmTest = config("evmTest") extend Test
  val PrecompiledContracts = config("precompiledContracts") extend Test

  coverageExcludedPackages := "io\\.iohk\\.ethereum\\.extvm\\.msg.*"

  Test / testOptions += Tests.Argument("-l", "iele")
  val Iele = config("iele") extend Test
  Iele / testOptions -= Tests.Argument("-l", "iele")
  Iele / testOptions += Tests.Argument("-n", "iele")

  node
    .configs(Integration, Benchmarks, EvmTest, PrecompiledContracts, Iele)
    .settings(
      inConfig(Integration)(
        Defaults.testSettings ++ BloopDefaults.configSettings ++ Seq(parallelExecution in Test := false)
      ): _*
    )
    .settings(inConfig(Benchmarks)(Defaults.testSettings ++ BloopDefaults.configSettings): _*)
    .settings(inConfig(EvmTest)(Defaults.testSettings ++ BloopDefaults.configSettings): _*)
    .settings(inConfig(PrecompiledContracts)(Defaults.testSettings ++ BloopDefaults.configSettings): _*)
    .settings(inConfig(Iele)(Defaults.testSettings ++ BloopDefaults.configSettings): _*)

When I run iele:test in SBT console it returns immediately saying no tests were run. Any ideas?
