尝试添加 xpath 断言时 groovy 脚本中出现 Nullpointer 错误

Question

我收到一个错误

java.lang.NullPointerException: Cannot invoke method getAssertionByName() on null object error at line: 5

但是我可以在测试用例中添加 xpath 断言。因为，我是 groovy 的新手，所以想知道：-

我收到此错误的原因是什么。
如何从 xpath 断言中的当前选项实现 select 的代码，以便我可以添加 xpath 而不是打印一些垃圾值（我已经打印了 "hello" 截至目前）。

log.info("Testing Start") def project = context.testCase.testSuite.project TSName = "ManagePostpayInsurance_1_0" StepName = "getInsuranceDetails_FC_004" project.getTestSuiteList().each { if(it.name == TSName) { TS = it.name it.getTestCaseList().each { TC =it.name def asserting = project.getTestSuiteByName(TS).getTestCaseByName(TC).getTestStepByName(StepName).getAssertionByName("XPath Match") log.info(asserting) if (asserting instanceof com.eviware.soapui.impl.wsdl.teststeps.assertions.basic.XPathContainsAssertion){ project.getTestSuiteByName(TS).getTestCaseByName(TC).getTestStepByName(StepName).removeAssertion(asserting) } def assertion = project.getTestSuiteByName(TS).getTestCaseByName(TC)getTestStepByName(StepName).addAssertion("XPath Match") assertion.path = "declare namespace cor='http://soa.o2.co.uk/coredata_1';\ndeclare namespace man='http://soa.o2.co.uk/managepostpayinsurancedata_1';\ndeclare namespace soapenv='http://schemas.xmlsoap.org/soap/envelope/';\n//man:getInsuranceDetails_1Response" assertion.expectedContent = "hello" } } } log.info("Testing Over")

我附上了下面的错误日志。

我被上面的问题困住了，非常感谢快速帮助！！！！非常感谢

给你：

由于您是分层进行的，因此不需要参考从 project 开始的完整方法链。
相反，您可以在浏览到步骤级别后直接访问步骤对象。这样就可以避免NPE了。

这里是固定脚本，见内联相关评论。

import com.eviware.soapui.impl.wsdl.teststeps.assertions.basic.XPathContainsAssertion
log.info("Testing Start")
def project = context.testCase.testSuite.project
def suiteName = "ManagePostpayInsurance_1_0"
def stepName = "getInsuranceDetails_FC_004"
project.testSuiteList.each { suite ->
    if(suiteName == suite.name) {
        suite.testCaseList.each { kase ->
            kase.testStepList.each { step ->
                if (stepName == step.name) {
                    //Note the change here, directly getting the object from step object
                    def asserting = step.getAssertionByName("XPath Match")
                    log.info(asserting)
                    if (asserting instanceof XPathContainsAssertion){
                        step.removeAssertion(asserting)
                    }
                    def assertion = step.addAssertion("XPath Match")
                    assertion.path = "declare namespace cor='http://soa.o2.co.uk/coredata_1';\ndeclare namespace man='http://soa.o2.co.uk/managepostpayinsurancedata_1';\ndeclare namespace soapenv='http://schemas.xmlsoap.org/soap/envelope/';\n//man:getInsuranceDetails_1Response"
                    assertion.expectedContent = "hello"            
                }
            }
        }
    }
}
log.info 'Testing Over'
