了解SOAP和Spock测试，No Such Property错误

Question

所以我遇到以下代码的麻烦，我看不出是什么问题。我已经多次尝试，如注释掉的代码所示，但它似乎没有缓解这个问题。 每次我尝试运行测试时，我都会收到错误：“没有这样的属性：exp为类：SpockTestSOAP”。任何帮助将不胜感激。

@Test
@Unroll
public void 'Web service generateSolution correctly truncates integer division: (#exp) is #expectedResult'() {
    /*when: 'the an integer division expression is evaluated'
    String result = generateSolution(exp);
    then: 'the result correctly truncates the exact expression'
    result == expectedResult*/
    expect:
    generateSolution(exp) == expectedResult
    where:
    exp || expectedResult
    "1/3" || "0"
    "5/2" || "2"
    "13/8" || "1"
    "126/5" || "25"
}
