Sbt will not run ScalaTest tests

Question

I run Scala 2.10.3 and sbt 0.13.5 and faintly follow Twitter scala sbt tutorial I came across a minor issue. unit test will not run at all.

my build.sbt:

 libraryDependencies += "org.scalatest" % "scalatest_2.10" % "2.1.7" % "test" 

my test class:

 package com.twitter.sample import collection.mutable.Stack import org.scalatest._ object SimpleParserSpec extends FlatSpec with Matchers { "SimpleParser" should "work with basic tweet" in { val parser = new SimpleParser val tweet = """{"id":1, "text":"foo"}""" parser.parse(tweet) match { case Some(parsed) => { parsed.text should be ("foo") parsed.id should be (1) } case _ => fail("didn't parse tweet") } } } 

and this is the result of running sbt test in the project folder:

 [info] Loading global plugins from C:\Users\Slench\.sbt\0.13\plugins [info] Set current project to twitter-sbt (in build file:/C:/Users/Slench/Desktop/twitter-sbt/) [info] Run completed in 36 milliseconds. [info] Total number of tests run: 0 [info] Suites: completed 0, aborted 0 [info] Tests: succeeded 0, failed 0, canceled 0, ignored 0, pending 0 [info] No tests were executed. [success] Total time: 0 s, completed 05-06-2014 20:19:11 

I'm not sure what is going wrong, all the files are in the correct folders, everything compiles without errors or warnings, but it will not run my test ... Any help?

Answer 1

Change SimpleParserSpec from object to class and it should work.

In particular, change the line

 //bad object SimpleParserSpec extends FlatSpec with Matchers 

to

 //good class SimpleParserSpec extends FlatSpec with Matchers
