[SoapUI] 通过Groovy写文本文件

如果文件已经存在，先删除，然后向文件中追加失败信息

if(maxRecordFail>0){

    def testResultFile = new File(projectDir+"\\TestResult\\PA_Integration Testing\\"+ currentStepName+".txt")  

     if (testResultFile.exists()) {

         testResultFile.delete()

     }

    for(j=0; j<maxRecordFail; j++){

        String currentFailMessage = failMessageList.get(j)

        log.error currentFailMessage

        testResultFile.append(currentFailMessage+"\n" )

    }

    assert false,failMessageList.get(0)

}
