Question

我收到错误

java.lang.NullPointerException：无法在第5行的null对象错误上调用方法getAssertionByName（）

但是我能够在测试用例中添加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。
如何在xpath断言中为选择当前选项实现代码，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”）。

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")

我已附上以下错误日志。

我很难坚持上述问题，快速帮助真的很感激!!!! 非常感谢你

你走了：

由于您要通过层次结构，不需要从project开始引用完整的方法链。
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。

这是固定脚本，请参阅内联相关评论。

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'

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