To avoid such problems, use HamcrestSupport.that:
...

gradle int-n:

repositories {
    mavenCentral()
    maven { url "http://oss.sonatype.org/content/repositories/snapshots/" }
}
dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.4.11'

    testCompile 'org.spockframework:spock-core:1.0-groovy-2.4'
    testCompile 'org.spockframework:spock-spring:1.0-groovy-2.4'
    testRuntime 'cglib:cblib-nodep:3.1'
    testRuntime 'org.objenesis:objenesis:2.1'

    Indicates which objects/classes are the subjects of a specification.
    If applied to a field, indicates that the field holds the subject of the specification.
    If applied to a class, indicates that the classes listed as
    annotation arguments are the subjects of the specification.
    Currently, this annotation has only informational purposes.

Interaction/Mocking

feature method blocks:
setup/given
expect
    no side-effects, just inputs and results, contains only conditions and variable definitions
when
then
    tests code with side effects
cleanup
    always invoked even if previous exceptions
where
    must be the last block, contains table-like data
    can use | or || as separator

@Unroll
def "crew member name: '#name' length: #length"() {
    expect:
        name.length() == length
    where:
        name     | length
        "Spock"  | 5
        "Kirk"   | 4
        "Scotty" | 6
}
...
    where:
        name << ["Spock", "Kirk", "Scotty"]
        length << [5, 4, 6]
...
        name << sql.execute("select name, age, sex from customer")
        length = name.length() // derived value
...
        [name,length] << [["Spock",5],["Kirk",4],["Scotty",6]]
...

Fields:
simple fields are new for each feature method.
@Shared
    shared


Fixture methods:
def setup() {...}
def cleanup() {...}

def setupSpec() {...}
def cleanupSpec() {...}
- may only access @Shared and static fields


Configuration:

~/.spock/SpockConfig.groovy or on CP or with -Dspock.configuration

runner {
    filterStackTrace false
    include Fast
    exclude Slow
    optimizeRunOrder true
}

@Fast
class MyFastSpec extends Specification {
    def "I'm really fast!"() { expect: true }
    @Slow
    def "sorry but I'm slow"() { expect: false }
}


Interesting:
Spock (at settings.gradle) change the "build.gradle" names to "spring.name" i.e.

Conditions:
PollingConditions
AsyncConditions


Deep Collections Comparison:

    def collectMaps(e) {
        e.with{
            if (it instanceof Map) {
                [it] + it.values().collect{ collectMaps(it) }
            } else if (it instanceof Collection) {
                it.collect{ collectMaps(it) }
            } else {
                []
            }
        }.flatten()
    }
