testing - スポック MissingMethodException

Question

私は同様の仕様のように見えるものを持っています:

def "my spec"(Record record) {
    given: 
        Something something = getSomething()
    and: 
        otherThing = getOtherThing()

    doFlow(something, record)
    if (record.someType = Types.SOME_SPECIFIC_TYPE) {
        doFlow(something, record)
    } 
}

def doFlow(Something something, Record record) {
    when:
         //code
    then:
         //asserts

    when:
         //code
    and: 
         //mode code
    then:
         //code
}

ただし、実行時に次のようになりますgroovy.lang.MissingMethodException: No signature of method doFlow() is applicable for arguments Something, Record values: [given values]。
