Excluding a ScalaTest test when calling my tests from within sbt

Question

I want to write a test that calls a remote server and validates the response because the server may change (it's not under my control). To do this I figure I'd give it a tag (RemoteTest) and then exclude it when calling the runner:

sbt> test-only * -- -l RemoteTest

However, when doing this all my tests are run, including RemoteTest. How do I call the runner from within sbt so that it is excluded?

Answer 1

If you have the following:-

package com.test

import org.scalatest.FlatSpec
import org.scalatest.Tag

object SlowTest extends Tag("com.mycompany.tags.SlowTest")
object DbTest extends Tag("com.mycompany.tags.DbTest")

class TestSuite extends FlatSpec {

  "The Scala language" must "add correctly" taggedAs(SlowTest) in {
      val sum = 1 + 1
      assert(sum === 2)
    }

  it must "subtract correctly" taggedAs(SlowTest, DbTest) in {
    val diff = 4 - 1
    assert(diff === 3)
  }
}

To exclude DbTest tag, you would do:-

test-only * -- -l com.mycompany.tags.DbTest

Note that you'll need to include the full tag name. If it's still not working for you, would you mind sharing part of source code that's not working?
