I have an interesting problem with testing using the WithApplication scope from Play 2.1.1.
Here is my code:
import play.api.test.{FakeApplication, WithApplication}
import org.specs2.mutable.Specification
class TestSpec extends Specification {
"Test" should {
"fail" in {
true === false
}
"fail as well" in new WithApplication() {
true === false
}
"fail with extreme prejudice" in new WithApplication(FakeApplication()) {
true === false
}
}
}
I would expect all 3 of these to fail but in this case only the first one failed.
[info] Total for specification TestSpec
[info] Finished in 21 ms
[info] 3 examples, 1 failure, 0 error
[info]
[error] Failed: : Total 4, Failed 1, Errors 0, Passed 3, Skipped 0
[error] Failed tests:
[error] TestSpec
Is there some trick I'm missing here?
I'm using Scala 2.10.2, sbt 0.12.2, Play 2.1.1 and runnning on Java 7 U40.
Thanks in advance.
You should try a latest version of Play or the latest version of specs2 (2.2.3) where this issue has been fixed.

I'm using Scala Play 2.7.x (the project is available here Play-Silhouette-Seed) and would like to test my daos. I have put together this simple one first to check what's the "new pattern" for testing play + slick + guice in 2.7.x:
package models.daos
import java.util.UUID
import org.specs2.mock._
import org.specs2.mutable._
import utils.AwaitUtil
import javax.inject.Inject
import models.generated.Tables.LoginInfoRow
class LoginInfoDaoSpec #Inject() (loginInfoDao: LoginInfoDao) extends Specification with Mockito with AwaitUtil {
"Creating a new LoginInfo" should {
"save it in the empty database" in {
loginInfoDao.create(LoginInfoRow(0, UUID.randomUUID().toString, UUID.randomUUID().toString))
loginInfoDao.findAll.size should beEqualTo(1)
}
}
}
Unfortunately, the guice dependency LoginInfoDao is not being provided to my test and then I get the error:
[play-silhouette-seed] $ testOnly models.daos.LoginInfoDaoSpec
[info] Done compiling.
[error] Can't find a suitable constructor with 0 or 1 parameter for class models.daos.LoginInfoDao
[info] ScalaTest
[info] Run completed in 1 second, 966 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.
[error] Error: Total 1, Failed 0, Errors 1, Passed 0
How do I get guice loading the needed modules for my test-cases?
A module is defined as:
class SilhouetteModule extends AbstractModule with ScalaModule {
override def configure() {
// ...
bind[LoginInfoDao].to[LoginInfoDaoImpl]
// ...
}
}
and I have an application.test.conf available defined as:
include "application.conf"
slick.dbs {
default {
profile="slick.jdbc.MySQLProfile$"
db.driver="com.mysql.cj.jdbc.Driver"
db.url="jdbc:mysql://localhost:3306/mytestdb?useUnicode=true&searchpath=public&serverTimezone=CET"
db.user="dev"
db.password="12345"
}
}
You should use another database for testing, H2 is the common choice.
class Module extends AbstractModule with ScalaModule {
...
}
With that name you need to let play know there is a Module to load, if you call it Module, it automatically know what to load and should work just fine (if you only need 1 module in testing)
If that doesn't work let me know
I have hello world scala native app and wanted to run small scala test to this app I use the usual test command but it's throw an exception :
NativeMain.scala
object NativeMain {
val p = new Person("xxxx")
def main(args: Array[String]): Unit = {
println("Hello world")
}
}
class Person(var name: String)
}
NativeTest.scala
import org.scalatest.{FlatSpec, Matchers}
class NativeTest extends FlatSpec with Matchers {
"name" should "the name is set correctly in constructor" in {
assert(NativeMain.p.name == "xxxx")
}
}
I run test command in the sbt shell and got this error

There is an open issue to add Add support for Scala Native #1112 and according to cheeseng:
3.1.0-SNAP6 and 3.2.0-SNAP10 are the only 2 versions (as of the time of writing) that supports scala-native
Try importing scalatest_native0.3_2.11 like so
libraryDependencies += "org.scalatest" % "scalatest_native0.3_2.11" % "3.2.0-SNAP10"
scalatest-native-example is a working example showing how to use scalatest with scala-native.
versions:
http4s: 0.18.1
specs2: 4.0.0
I'm using http4s and writing unit test for routers, but there are little documents about headers assertion.
When code below is executed, it can be compiled, but fails.
code:
import cats.effect.IO
import org.http4s._
import org.http4s.dsl.io._
import org.http4s.headers._
import org.http4s.testing.Http4sMatchers
import org.specs2.mutable.Specification
class RedirectSpec extends Specification with Http4sMatchers {
"testing" >> {
val response: IO[Response[IO]] = Found(Location(Uri.unsafeFromString("")))
response must returnStatus(Found)
response must returnValue(
haveHeaders(
Headers(
`Content-Length`.zero,
Location(Uri.unsafeFromString(""))
)
)
)
}
}
output:
$ sbt "testOnly RedirectSpec"
...
[info] RedirectSpec
[error] x testing
[error] the headers 'Headers(Content-Length: 0, Location: )' is not the same as Headers(Content-Length: 0, Location: ) (RedirectSpec.scala:13)
[info] Total for specification RedirectSpec
[info] Finished in 655 ms
[info] 1 example, 1 failure, 0 error
[error] Failed: Total 1, Failed 1, Errors 0, Passed 0
[error] Failed tests:
[error] RedirectSpec
[error] (test:testOnly) sbt.TestsFailedException: Tests unsuccessful
What is difference between actual and expected value? If it's wrong, please tell me how to make assertion about headers.
This is almost certainly a bug, since one of Http4s's own tests does something similar and fails when I run it with Http4sMatchers with a similar error. I've reported a bug.
I've created and am also using some external Scalacheck generators from Lists and appropriate types, using Gen.oneOf(List[T]) . I think it would be occasionally useful to return a placeholder for an empty value. Currently the lists are populated. How should I go about this? Do I try to append an empty type to the end of the list? If so how do I go about that? If not, how else can I get my generators to add an empty value. It seems straightforward, but I am having trouble figuring it out right now.
import org.scalatest.FlatSpec
import org.scalacheck.Gen
import org.scalacheck.Prop.exists
import org.scalatest.prop.PropertyChecks
class EventFieldGeneratorTest extends FlatSpec with PropertyChecks {
behavior of "Gen.option"
it should "occasionally return None" in {
val colors = Gen.oneOf("Blue", "Red", "Green", "Yellow")
val opt = Gen.option(colors)
val list = Gen.listOfN(20, opt)
val p1 = exists(list)(_ == None)
p1.check
}
}
Can anybody explain why my test is giving up?
Testing started at 10:31 AM ... ! Gave up after only 0 passed tests. 501 tests were discarded.
Process finished with exit code 0
How can I mark that as a failed result for ScalaTest? Is it a bad idea for me to use Flatspec?
Maybe I should be using something other than check...
Here's the documentation I used to sort it on. On the Scalatest page:
http://www.scalatest.org/user_guide/writing_scalacheck_style_properties
I don't think there's anything flawed with trying to use lists with optional values. There are just a few issues you're running in to that are giving you trouble.
It's confusing, but if you're using the Scalatest framework, you need to use the Scalatest infrastructure to use Scalacheck. So you'll need to use Scalatest matchers, and write Scalatest-flavored properties (using it's forAll), but you'll still use Scalacheck's generators directly.
For some reason the type inference between lists and Option type is giving you trouble. If you use the shouldBe matcher,
x shouldBe(None)
you'll get a relevant runtime error from Scalatest:
[info] - should occasionally return None *** FAILED ***
[info] TestFailedException was thrown during property evaluation.
[info] Message: List() was not equal to None
[info] Location: (GenTest.scala:13)
[info] Occurred when passed generated values (
[info] arg0 = List() // 5 shrinks
[info] )
[info] Run completed in 1 second, 621 milliseconds.
[info] Total number of tests run: 1
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 0, failed 1, canceled 0, ignored 0, pending 0
You shouldn't be matching a list with an Option type. You need to be matching with the Scalatest "container" matcher should contain
import org.scalatest.FlatSpec
import org.scalatest.Matchers
import org.scalacheck.Gen
import org.scalatest.prop.PropertyChecks
class EventFieldGeneratorTest extends FlatSpec with Matchers with PropertyChecks {
behavior of "Gen.option"
it should "occasionally return None" in {
val colors = Gen.oneOf("Blue","Red","Green","Yellow")
val opt = Gen.option(colors)
val list = Gen.listOfN(20,opt)
forAll(list) { (xs: List[Option[String]]) =>
xs should contain (None)
}
}
}
This gives you a successful property check:
[info] EventFieldGeneratorTest:
[info] Gen.option
[info] - should occasionally return None
[info] ScalaTest
[info] Run completed in 1 second, 9 milliseconds.

I currently testing a web service, and I keep on running into an error where the web service test is failing because it is timing out. I'm trying to extends that timeout to be 5 seconds long. I'm trying to mimic a solution that some one posted on the Scala Spray google groups forum to no avail. Here is the code I am trying to use in my test:

playerScore.playerId must be ("00-0031237")

can anyone provide any insight as what to what I can do to extend the time timeout time on Scala Spray?
Here is the solution
implicit def default(implicit system: ActorSystem) = RouteTestTimeout(new DurationInt(5).second.dilated(system))
I have to explicitly pass for system parameter to the dilated method because of implicit conflicts in Scala.
Similar to the previous answer, but a bit shorter
implicit def default(implicit system: ActorSystem) = RouteTestTimeout(5.seconds)
Here is the change which you will need to make -
implicit def default(implicit system: ActorSystem): RouteTestTimeout = RouteTestTimeout(new DurationInt(8).second.dilated(system))
