I am trying to run my tests with: sbt and then test.
My build.sbt looks like this
lazy val scalatest = "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
lazy val root = (project in file(".")).
settings(
name := "highlight2pdf",
version := "0.1",
scalaVersion := "2.11.6",
libraryDependencies += scalatest
)
And i just put the example test on test/scala
import collection.mutable.Stack
import org.scalatest._
class ExampleSpec extends FlatSpec with Matchers {
"A Stack" should "pop values in last-in-first-out order" in {
val stack = new Stack[Int]
stack.push(1)
stack.push(2)
stack.pop() should be (2)
stack.pop() should be (1)
}
it should "throw NoSuchElementException if an empty stack is popped" in {
val emptyStack = new Stack[Int]
a [NoSuchElementException] should be thrownBy {
emptyStack.pop()
}
}
}
Still it always show:
[info] No tests were executed.
Any thoughts on why it's not working?
ScalaTest is one of the main testing libraries for Scala projects, and in this lesson you'll see how to create a Scala project that uses ScalaTest. You'll also be able to compile, test, and run the project with sbt.
sbt maps each test class to a task. sbt runs tasks in parallel and within the same JVM by default.
The directory structure isn't the correct convention for sbt
to find ExampleSpec.scala
by default.
├── built.sbt
├── src
│ └── test
│ └── scala
│ ├── ExampleSpec.scala
Change it to the structure above and run sbt test
in the top level directory and it should work. Likewise, scala source would go in src/main/scala
and would get compiled.
