No tests are run

[xanderdunn]

This is the first time I'm attempting to use gradle and scalatest. I have scalatest working with sbt, but I'm attempting to switch over to gradle.

My build.gradle:

repositories {
    mavenCentral()
}
apply plugin: 'scala'
dependencies {
    compile 'org.scala-lang:scala-library:2.11.7'
    testCompile 'org.scalatest:scalatest_2.11:2+'
    testRuntime 'org.pegdown:pegdown:1.1.0'
}

I have my test sources in src/test/scala, as shown in the gradle docs.

gradle --version:

When I run grade test, I get this:

Xanders-MacBook-Pro:reinforcementLearning admin$ gradle test

BUILD SUCCESSFUL

Total time: 0.654 secs

It's successfully compiling the project, but it isn't running any of the tests. I suspect I've simply made an elementary mistake in my build.gradle.

Using gradle 2.6 you can use the plugin syntax to apply this plugin (there should be a link in the readme) - at the moment it looks as though you have only applied the scala plugin which supports junit and testng?

[xanderdunn]

@maiflai Thanks for your help!

I'm sure I'm just being dense with my gradle setup, but I'm still not having luck. I think you're referring to the build scripts shown on the gradle plugins page.

With this, it again builds but runs no tests:

repositories {
    mavenCentral()
}
apply plugin: 'scala'
dependencies {
    compile 'org.scala-lang:scala-library:2.11.7'
    testCompile 'org.scalatest:scalatest_2.11:2+'
    testRuntime 'org.pegdown:pegdown:1.1.0'
}
buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "com.github.maiflai:gradle-scalatest:0.9"
  }
}

apply plugin: "com.github.maiflai.scalatest"

Do you have an example of a working build.gradle that's using scalatest?

[xanderdunn]

Ok, this ended up working fine for me:

repositories {
    mavenCentral()
}
apply plugin: 'scala'
dependencies {
    compile 'org.scala-lang:scala-library:2.11.7'
    testCompile 'org.scalatest:scalatest_2.11:2+'
    testRuntime 'org.pegdown:pegdown:1.1.0'
}
buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "com.github.maiflai:gradle-scalatest:0.9"
  }
}

apply plugin: "com.github.maiflai.scalatest"

The key was that after setting this to my build.gradle, I had to not merely run gradle test, but first I had to gradle clean.

[maiflai]

Ah, yes - gradle caches the results of tasks based on inputs and outputs - if you make changes to the build script it can require a clean to purge existing state.

You shouldn't have to run clean again - tests will re-run automatically if you modify them or the main source that they are based on. Otherwise you will see the task marked as up to date. Sorry for the confusion.

[maiflai]

Sorry - I've been travelling away from a keyboard for the past few days.

Just following up on the modifications to your build script - the plugin syntax I was referring to is the simplified variant at the bottom of the plugins page:

plugins {
  id "com.github.maiflai.scalatest" version "0.9"
}

should be sufficient for a simple project; this automates the manual configuration of repository, dependency and plugin application.

@maiflai

Thanks, this ended up working for me. It just took me some time to figure out that I had to put this plugins{} at the top of my build.gradle, but after any buildscript{} blocks.
