This question asks how to get an html report with sbt and ScalaTest. The answers reference Scala test 2.0 and do not appear to work for me with ScalaTest 3.0
I declare ScalaTest by
lazy val scalaTest = Seq("org.scalatest" %% "scalatest" % "3.0.8" % "test",
"org.scalactic" %% "scalactic" % "3.0.8",
"org.scalamock" %% "scalamock" % "4.4.0" % Test)
and then use it by
ThisBuild / Test / testOptions += Tests.Argument(TestFrameworks.ScalaTest, "-h", "target/test-reports")
and
lazy val foo = (project in file("foo")).
settings(libraryDependencies ++= scalaTest)
This fails with
[error] java.lang.NoClassDefFoundError: org/pegdown/PegDownProcessor

The question suggests using "test->*" for the test declaration. Trying
lazy val scalaTest = Seq("org.scalatest" %% "scalatest" % "3.0.8" % "test->*" excludeAll (
ExclusionRule(organization="org.junit", name="junit")),
"org.scalamock" %% "scalamock" % "4.4.0" % Test
)
instead fails with

followed by errors that look like the implicit conversions for FlatSpec are not present and are probably follow-on errors from the above.
Is there a way to do this with ScalaTest 3.0?
Try adding pegdown dependency like so
libraryDependencies += "org.pegdown" % "pegdown" % "1.6.0" % Test
Note in ScalaTest 3.1.x pegdown is replaced with flexmark-java as per resolve #1201 replace pegdown with flexmark-java #1229
