how to make scalatest generate html report through sbt

Question

The way to do this for specs2 based test in sbt is

(testOptions in Test) += Tests.Argument(TestFrameworks.Specs2, "html")

but how about scalatest? I've done lots of Google search, but cannot find a good explanation/solution.

Answer 1

so two things I need to do...

I. use any scalatest artifact after 2.0.M5b. For me, I added this dependency,

org.scalatest" %% "scalatest" % "2.0.M6" % "test->*" excludeAll ( ExclusionRule(organization="org.junit", name="junit") )

"test->*" is necessary, otherwise dependencies needed to generate the html wont be downloaded. (There must be a better way than this)

II. In build.sbt, add

(testOptions in Test) += Tests.Argument(TestFrameworks.ScalaTest, "-u", "target/report")

Answer 2

beware with that setting.

org.scalatest" %% "scalatest" % "2.0.M6" % "test->*

It pulls out some junit:junit:3.8.1 dependency which ivy fails to resolve. see this bug

this is a better way to do it in ScalaTest 2.0

testOptions in Test += Tests.Argument(TestFrameworks.ScalaTest, "-u", "target/test-reports")

This works well in Jenkins
