Testing with Spock

Old Forum Archive

Given: gradle version is 2.2.1

Task example:

class TestTask extends DefaultTask {
 PegDownProcessor markdown =
new PegDownProcessor(Extensions.ALL);
   @TaskAction
 private void generateDocs() {
  String str = markdown.markdownToHtml '##Hello'
  println str
 }
}

I have written task like that and added by plugin. Plugin just adds task with some name with current type of task.

void apply(Project project) {
  project.tasks.create('generateDocs', TestTask)
 }

When have I written test with JUnit all was fine but when I have tried to use spock, I had a lot of problem.

dependncies for spock in buildSRC:

compile gradleApi()
compile localGroovy()
compile group: 'org.pegdown', name: 'pegdown', version: '1.4.2'
testCompile 'org.spockframework:spock-core:0.7-groovy-2.0'

Doesn’t work even with empty spec:

class TestPluginSpec extends Specification {
  }

and produce next stacktrace:

com.test.gradle.plugin.TestPluginSpec > initializationError FAILED
    org.spockframework.util.InternalSpockError
        Caused by: java.lang.ExceptionInInitializerError at TestPluginSpec.groovy:-1
            Caused by: groovy.lang.GroovyRuntimeException at TestPluginSpec.groovy:-1

When I have changed spock version to:

testCompile 'org.spockframework:spock-core:1.0-groovy-2.3-SNAPSHOT'

and add repositories:

repositories{
 maven { url 'http://repo1.maven.org/maven2' }
 maven { url 'http://oss.sonatype.org/content/repositories/snapshots' }
}

I couldn’t instantiate my task and as I understood this problem related to pegdown processor instantiation, because for another type of fields(String, List) all works fine. I can move ‘new PegDownProcessor(Extensions.ALL)’ to method and test will pass too. As example:

lass TestTask extends DefaultTask {
 PegDownProcessor markdown
   @TaskAction
 private void generateDocs() {
  markdown =
=
new PegDownProcessor(Extensions.ALL)
  String str = markdown.markdownToHtml '##Hello'
  println str
 }
}

For both cases Junit and Spock I have used one setup method of tests with body:

void setup() {
  project = ProjectBuilder.builder().build()
  project.apply plugin: TestPlugin
 }

if I use gradle 1.9 and ‘testCompile ‘org.spockframework:spock-core:0.7-groovy-1.8’’ in both cases everything is good. So I think this problem depends on version of spock and groovy in gradle. Can you help me how I should use spock with gradle version 2.0 and higher?

As I have tested this problem related to all version of gradle 2.x and last release candidate gradle 2.3-rc-3**
