Greenlight is a BDD style testing framework for Scala and Scala.js, which provides an extensible matcher API with fluent syntax.
The project is at a very early stage of development, so it should be used with caution.
Add the following lines to your sbt build definition:
libraryDependencies += "com.greencatsoft" %%% "greenlight" % "0.3"And override the default testing framework like below:
testFrameworks := Seq(new TestFramework("com.greencatsoft.greenlight.Greenlight"))If you want to test the latest snapshot version instead, change the version to
0.4-SNAPSHOT and add Sonatype snapshot repository to the resolver as follows:
resolvers +=
"Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"Or more simply as,
resolvers += Resolver.sonatypeRepo("snapshots")object FrameworkTest extends TestSuite {
"The framework" should "be able to test equality" in {
(1 + 1) must be (2)
("A" + "B") should be ("AB")
"Scala.js" must not be ("overlooked!")
}
It should "be able to check if a collection is empty" in {
List(1, 2, 3) must not be (empty)
Seq.empty must be (empty)
}
It can "check if an option is defined or not" in {
val value = Some("value")
value must be (defined)
value should not be (empty)
None must be (empty)
None should not be (defined)
}
It can "also check if a string value is empty" in {
val emptyValue = ""
emptyValue must be (defined)
emptyValue must be (empty)
val nullValue: String = null
nullValue should be (empty)
nullValue should not be (defined)
val value = "Scala"
value must not be (empty)
value should be (defined)
}
It can "also check if a collection contains an item or not" in {
val collection = Seq("a", "b", "c", "d")
collection must contain ("a")
collection must contain ("b")
collection must not contain ("e")
}
// You can skip a test case by using 'might' instead of 'should/must/can'.
It might "not be ready for prime time" in {
"You" should be ("joking!")
}
It can "be used to test if an exception is thrown" in {
A_[NullPointerException] should be_thrown_in {
(null).toString
}
A_[NullPointerException] should not be_thrown_in {
println("Scala.js rocks!")
}
}
}
object LifeCycleTest extends TestSuite with BeforeAndAfter {
var specification: Option[String] = None
before { (s: Statement) =>
this.specification = Some(s.description)
}
after {
this.specification = None
}
"BeforeAndAfter trait" can "be used to be notified before and after a specification" in {
specification should not be (empty)
specification foreach { it =>
it should be ("BeforeAndAfter trait can be used to be notified before and after a specification")
}
}
}
