Disposing resource inside spock feature method at arbitrary places

Inside a spock test we want to create a resource and make sure its disposed correctly regardless of the outcome of the test result.

We tried the approach below. But spock is not executing tests when the test code is wrapped inside a closure.

import spock.lang.Specification

class ExampleSpec extends Specification {

    def wrapperFunction(Closure cl) {
        try {
            cl()
        } finally {
            // do custom stuff
        }
    }

    def "test wrapped in closure"() {
        wrapperFunction {
            expect:
            1 == 1
            println "will not execute!"
        }
    }
}

What is the best approach on creating and disposing a resource inside a spock test.

setup() and cleanup() are not viable solutions since creating and disposing should be possible at arbitrary points inside the feature method.

You can use setup and cleanup block inside of the test case (feature method) like this:

class ReleaseResourcesSpec extends Specification {
    void 'Resources are released'() {
        setup:
        def stream = new FileInputStream('/etc/hosts')

        when:
        throw new IllegalStateException('test')

        then:
        true

        cleanup:
        stream.close()
        println 'stream was closed'
    }
}

Code from the cleanup block is always executed although the test fails or if there is any exception. See the result of the above example: enter image description here

So it is similar to setup() and cleanup() methods but in this case you can have different setup and clean up code for each feature method.
