Please assume the normal "newbie" appologies.
I'm using scala 2.12.10; In build.sbt I added ScalaTest:
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.8" % "test"
I'm adding some scala.js to an existing java project so my scala source paths are normal but I made some empty directories for java and resources and use a different target so there would be no collision with existing code:
javaSource in Compile := baseDirectory.value / "src/main/scalajs_java"
javaSource in Test := baseDirectory.value / "src/test/scalajs_java"
resourceDirectory in Compile := baseDirectory.value / "src/main/scalajs_resources"
resourceDirectory in Test := baseDirectory.value / "src/test/scalajs_resources"
target := baseDirectory.value / "scalajs_target"
I put the ScalaTest example file ExampleSpec.scala in src/test/scala/ExampleSpec.scala. The example ran fine using org.scalatest.run as described in http://www.scalatest.org/.
The test classpath looks reasonable, I thought:
sbt:RedsPro-ScalaJS> show test:fullClasspath

After compiling, the test is where I would expect it:
> ls scalajs_target/scala-2.12/test-classes/
ExampleSpec.class ExampleSpec.sjsir JS_DEPENDENCIES org/
However, sbt apparently isn't convinced there are any tests:

A point in the right direction would be greatly appreciated.
You need to use %%% instead of %% when depending on ScalaTest. In general, you always need to use %%% in Scala.js.

How do I can specify the test from the build.sbt file , I wanted to run one test only and I used the filter as in the sbt docs, but it doesn't work with me, this is my code I have two test classes and in my sbt I specify test1 to be rub but it seems that the two test are running at the same time any one know what I should do ?
Test1Demo.scala
import org.scalatest.{FlatSpec, Matchers}
class Test1Demo extends FlatSpec with Matchers{
"value of x " should " be 9 " in { assert(my.App.x == 9) }
}
Test2Demo.scala
import org.scalatest.{FlatSpec, Matchers}
class Test2Demo extends FlatSpec with Matchers{
"value of y " should " be 8 " in { assert(my.App2.y == 8) }
}
build.sbt
version := "0.1"
scalaVersion := "2.12.8"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.5" % Test
testOptions in Test := Seq(Tests.Filter(s => s.startsWith("Test1")))
the output :

If you want to run value of x test from Test1Demo:
testOnly *Test1Demo -- -z value
This sbt command will run only the tests whose name includes the substring "value".
For exact match rather than substring, use -t instead of -z.
Pay attention to -- (two -, not one)
I'm using an build.sbt which has cross compile settings and basically is an adapted version of "Play with scala-js example" and having some trouble getting a clean setup for my tests. Specifically, when running my server tests, my client tests also get executed (which is something that I want to avoid).
I followed the instructions from Cannot get uTest to see my tests
and added
libraryDependencies += "com.lihaoyi" %%% "utest" % "0.3.0"
My tests for some reason didn't get executed until I added
testFrameworks += new TestFramework("utest.runner.Framework")
to every project definition. Also not adding
"com.lihaoyi" %% "utest" % "0.3.1" % "test"
to the server side triggers a series of
not found: object utest [error] import utest._
-style errors.
To my impression I shouldn't have to add these additional settings at all if having a clean setup. Here's my sbt file:
import sbt.Project.projectToRef
lazy val clients = Seq(client)
lazy val scalaV = "2.11.7"
lazy val server = (project in file("server")).settings(
scalaVersion := scalaV,
scalaJSProjects := clients,
pipelineStages := Seq(scalaJSProd/*, gzip*/),
resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases",
libraryDependencies ++= Seq(
"com.vmunier" %% "play-scalajs-scripts" % "0.3.0",
"be.doeraene" %% "scalajs-pickling-play-json" % "0.4.0"
),
testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(PlayScala).
aggregate(clients.map(projectToRef): _*).
dependsOn(sharedJvm)
lazy val client = (project in file("client")).settings(
scalaVersion := scalaV,
persistLauncher := true,
persistLauncher in Test := false,
libraryDependencies ++= Seq(

).enablePlugins(ScalaJSPlugin, ScalaJSPlay).
dependsOn(sharedJs)
lazy val shared = (crossProject.crossType(CrossType.Pure) in file("shared")).
settings(scalaVersion := scalaV,
libraryDependencies ++= Seq(
"com.lihaoyi" %%% "utest" % "0.3.1",
"be.doeraene" %%% "scalajs-pickling-core" % "0.4.0",
"com.lihaoyi" %%% "pprint" % "0.3.6"
),
testFrameworks += new TestFramework("utest.runner.Framework")
).
jsConfigure(_ enablePlugins ScalaJSPlay)
lazy val sharedJvm = shared.jvm
lazy val sharedJs = shared.js
// loads the Play project at sbt startup
onLoad in Global := (Command.process("project server", _: State)) compose (onLoad in Global).value
And here a summary of my problems:
when I run client/test, only client tests are executed
when running play-with-scalajs-example/test, client + shared tests are executed
and strangely when running server/test my server AND client tests are executed
How could I modify my project setup to
find my server tests when running server/test
running all tests when running play-with-scalajs-example/test
and additionally including the shared tests when running server/test or client test?
And on another node, is there a way to disable scalatest? It leads to a rather unreadable testoutput:

Thanks a bunch and kind regards
sjrd's comment about removing aggregate pointed me to right path.
Removing it stopped
server/test
from executing both server and client tests. As sjrd pointed out, the aggregate function used also runs every task that is run on server on the client.
Aggregation means that running a task on the aggregate project will
also run it on the aggregated projects.
(See: sbt doc)
As I also wanted to run shared tests on both client and server project when running test, I modified the aggregate function for the server project definition and added an additional aggregate to the client project definition. :
Server def.:
lazy val server = (project in file("server")).settings(
scalaVersion := scalaV,
scalaJSProjects := clients,
pipelineStages := Seq(scalaJSProd/*, gzip*/),
resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases",
libraryDependencies ++= Seq(
"com.vmunier" %% "play-scalajs-scripts" % "0.3.0",
"be.doeraene" %% "scalajs-pickling-play-json" % "0.4.0",
"com.lihaoyi" %% "utest" % "0.3.1" % "test"
),
testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(PlayScala).
/*
* Executes shared tests compiled to JVM with server/test
*/
aggregate(projectToRef(sharedJvm)). // Former: aggregate(clients.map(projectToRef): _*). before
dependsOn(sharedJvm)
Client def.:
lazy val client = (project in file("client")).settings(
scalaVersion := scalaV,
persistLauncher := true,
persistLauncher in Test := false,
libraryDependencies ++= Seq(
"org.scala-js" %%% "scalajs-dom" % "0.8.0"
),
testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(ScalaJSPlugin, ScalaJSPlay).
/*
* Executes shared tests compiled to JS with client/test
*/
aggregate(projectToRef(sharedJs)).
dependsOn(sharedJs)
When running tests with play-with-scalajs-example/test now runs all tests, including the shared tests both compiled seperately for JS and JVM.
As for having to explicitly include the utest dependencies, it seems that client and server projects don't derive from crossProject and are thus disconnected - will look into finding a better way of handling that.
I'm trying to get uTest to work with ScalaJS and SBT. SBT is compiling the files, and uTest is running, but it simply ignores my tests. Try as I might I cannot find any difference between my code and the tutorial examples.
build.sbt:
enablePlugins(ScalaJSPlugin)
name := "Scala.js Stuff"
scalaVersion := "2.11.5" // or any other Scala version >= 2.10.2
scalaJSStage in Global := FastOptStage
libraryDependencies += "com.lihaoyi" %% "utest" % "0.3.0"
testFrameworks += new TestFramework("utest.runner.Framework")
src/test/scala/com/mysite/jovian/GeometryTest.scala:
package com.mysite.jovian
import utest._
object GeometryTest extends TestSuite {
def tests = TestSuite {
'addPoints {
val p: Point = new Point(3,4)
val q: Point = new Point(4,3)
val expected: Point = new Point(8,8)
assert(p.plus(q).equals(expected))
throw new Exception("foo")
}
'fail {
assert(1==2)
}
}
}
Output:

So it's definitely seeing the code, it just doesn't seem to think that "tests" contains any tests.
Otherwise, in the non-test code, SBT+ScalaJS seems to be working fine...
Thanks for any help, I am mystified.
Your mistake lies in the dependency on uTest:
libraryDependencies += "com.lihaoyi" %% "utest" % "0.3.0"
This is a JVM dependency. To use the Scala.js-enabled dependency, use %%% instead of %%, like this:
libraryDependencies += "com.lihaoyi" %%% "utest" % "0.3.0"
Additionally, you probably want this dependency only in the Test configuration, so add % "test" a the end:
libraryDependencies += "com.lihaoyi" %%% "utest" % "0.3.0" % "test"
I have a multi-module Play! application built with sbt and I have a problem on CI server with parallel tests and evolutions: when sbt starts tests and first starts evolution script, other fails because of "Database 'default' is in inconsistent state" for a while (until evolution script stops).
I know how to execute evolutions manually and how to run them from sbt, but I don't know how can I plug this configuration to sbt to ensure evolutions are applied only once and before all tests from all modules.
For reference I'm using following for running evolutions:
object ApplyEvolutions extends App {
OfflineEvolutions.applyScript(
new File("."),
this.getClass.getClassLoader,
args.headOption.getOrElse("default"))
}
And my sbt settings:
val runEvolution = taskKey[Unit]("Applies evolutions")
lazy val runEvolutionTask = runEvolution := {
val log = streams.value.log
val dbName = "default"
Run.executeTrapExit( {
log.info(s"Applying evolutions for database $dbName")
Run.run("controllers.ApplyEvolutions",
(fullClasspath in Compile).value.map { _.data },
Seq(dbName),
log
)(runner.value)
}, log )
}
lazy val runEvolutionsBeforeTests = Seq(
Tasks.runEvolutionTask,
(test in Test) <<= (test in Test) dependsOn Tasks.runEvolution
)
tl;dr Use alias

Here's an example of a task - sayHelloT - that's executed once before test in all subprojects. I use Specs2 as the testing framework.
import java.util.concurrent._
lazy val a = project
lazy val b = project
lazy val sayHelloT = taskKey[Unit]("Say Hello")
sayHelloT := {
val log = streams.value.log
log.info("Sleeping for 5 secs...")
TimeUnit.SECONDS.sleep(5)
log.info("Hello, my friend")

scalacOptions in Test ++= Seq("-Yrangepos")

I have a project where I want to compile twitter bootstrap as well as to prevent tests to be executed in parallel
def twitterBootstrapEntryPoints(base:File):PathFinder = {
(base / "app" / "assets" / "stylesheets" / "bootstrap" * "bootstrap.less") +++
(base / "app" / "assets" / "stylesheets" / "bootstrap" * "responsive.less") +++
(base / "app" / "assets" / "stylesheets" * "*.less")
}
val common = PlayProject(appName, appVersion,appDependencies, mainLang = SCALA).settings(
organization := appOrganization,
lessEntryPoints <<= baseDirectory(twitterBootstrapEntryPoints),
resolvers ++= commonResolvers).settings( inConfig(Test)(parallelExecution := false) : _* )
Edit:
To build twitter bootstrap, one should only compile bootstrap.less and responsive.less which import all the other files. in Compile everything works fine, when running in Test this does not work anymore, the compiler tries to compile all the .less files
This is what I see on the play console

Parallel execution of tests is set to false by default. You shouldn't have to include it in the configuration.
Documentation here: https://github.com/playframework/Play20/wiki/SBTSettings
In your setup, Play must be compiling all the less files in app/assets/stylesheets in production as well. Is this what you don't want? Or is it compiling everything in app/assets/stylesheets/bootstrap/ ?
