JUnit ClassRules in Spock

[grze...@gmail.com]

Hi all

I can't find information if @ClassRule is respected bu spock during execution.

I try to write some class rule which can do some @BeforeClass initializations, but I can't make spock to respect it.

I came up with this :

class SputnikWithParametersTest extends Specification {

    @ClassRule

    @Shared

    public static ClassParameters<int[]> PARAMETERS = ClassParameters.withParameters([[2, 2], [-2, 2]])

    static int a;

    static int b;

    @BeforeClass

    void before() {

        int[] parameter = PARAMETERS.getParameter()

        println("Parameters : ${parameter}")

        a = parameter[0]

        b = parameter[1]

    }

    def 'some'() {

        when:

            int abs = Math.abs(a)

        then:

            abs == b

    }

    def 'second'() {

        when:

            int abs = Math.abs(a)

        then:

            abs == b

    }

}

but spock didn't catch Class Rule.

When I change it to normal rule :

class SputnikWithParametersTest extends Specification {

    @Rule

    ClassParameters<int[]> PARAMETERS = ClassParameters.withParameters([[2, 2], [-2, 2]])

    int a;

    int b;

    def 'some'() {

        setup:

            int[] parameter = PARAMETERS.getParameter()

            println("Parameters : ${parameter}")

            a = parameter[0]

            b = parameter[1]

        when:

            int abs = Math.abs(a)

        then:

            abs == b

    }

    def 'second'() {

        setup:

            int[] parameter = PARAMETERS.getParameter()

            println("Parameters : ${parameter}")

            a = parameter[0]

            b = parameter[1]

        when:

            int abs = Math.abs(a)

        then:

            abs == b

    }

}

it started to process rule (so it support normal rules)

Have anyone successfully used Class Rules with Spock ?

Hi,

actually mechanism is working, but I have some issue in my class rule, I need to debug it. Sorry for spamming,

it seems that help change :

    static int a;

    static int b;

to 

    @Shared

    int a;

    @Shared

    int b;

it is probably of my leak of knowledge in groovy/spock beahvior.

Cheers,

we need remove public static modifier and just keep   @ClassRule @Shared ClassParameters<int[]> ...
