In two previous posts (Grails3.0 & Grails2.2) I described how to use Spock-Reports with Grails 3.0 and Grails 2.2.

Now, if you try to use it with Grails 2.5, it seems not to work from the start. The main problem I noticed was that even
when I run a trivial app and all spock tests are auto-created, I got an error message at the end of the tests:

So I tried to get rid of this error message by not forking the VM when running tests. To do that, simply set the fork-configuration
to false for the test environments (in BuildConfig.groovy)

grails.project.fork = [
    test: false,

Now, the rest seems to work the same as with Grails 2.2.4 with the only difference that Grails 2.5 uses Spock out of the box.
So we don't habe to configure it:

just open your grails-app/conf/BuildConfig.groovy file and add

repositories {
  //for spock-reports
  mavenRepo "http://jcenter.bintray.com"

to the repositories section and

dependencies {
  //for spock-reports
  test 'com.athaydes:spock-reports:1.2.5'  

to the dependencies section.

The standard reports are now generated and stored in build/spock-reports/..

Customizing your Reports

In order to store the generated reports in target/test-reports/spock/. you have to customize your reports as described in the documentation, you have to create a file called META-INF/services/com.athaydes.spockframework.report.IReportCreator.properties.
That sounds easier than it is, because it has to be in the classpath and for some Grails projects, it's not easy to find the right folder to put it.

For Grails 2.5, you will succeed by putting it in grails-app/conf/META-INF/services/com.athaydes.spockframework.report.IReportCreator.properties.

Here is a sample file which uses the template based reports:

# Name of the implementation class of the report creator
# Currently supported classes are:
#   1. com.athaydes.spockframework.report.internal.HtmlReportCreator
#   2. com.athaydes.spockframework.report.template.TemplateReportCreator

# Output directory (where the spock reports will be created) - relative to working directory

# If set to true, hides blocks which do not have any description

# Set properties of the report creator

this file specifies that the templates are located in grails-app/conf/spockreporttemplates and the output
will be written to target/test-reports/spock. A good idea is to start with the default templates spec-template.md and summary-template.md
