据了解，您需要执行数据 - 驱动测试，其中请求保存在目录中。

以前，提供了一种方法这里来循环数据并保存响应。

全部您现在可能需要的更改是在第一步 - 读取目录，并循环通过您的文件并将文件内容设置为请求并运行soap请求步骤。

 导入groovy.io.FileType 

 //将输入目录名改为
 def dir = new File（'path / to / input / dir'）
 dir.eachFile（FileType.FILES）{file  - > 

 //获取步骤
 def step = context.testCase.getTestStepAt（1）
 //将文件内容设置为测试步骤请求
 step.testRequest。 requestContent = file.text 
 log.info为step2设置新请求：$ {request}
 //运行step2 
 step.run（testRunner，context）
 } 
 //现在所有的订单都被执行了，现在需要退出步骤而不需要另外运行step2 
 //所以，跳转到step2，索引是2 
 testRunner.gotoStep（2） 
 

您可以继续使用上述链接中提到的其余步骤。

Requirement: To read the xml file from the folder and pass the contents of the file to Soap request.

Issue I am trying to read the file saved in the folder using groovy script, But unable to read the contents of the file. I am getting Null pointer exception while trying to print the contents of the xml file.

def fileList = []
new File("C:\\Users\\Documents\\Groovy Scripts\\requests").eachFile
{ f ->
if (f.isFile()&& f.name.endsWith('.xml'))
{
 def filename = f.name[0..-5]
 fileList.add(filename)
 log.info filename

 }
}
if (fileList.size() <1)
{
testRunner.fail("No request files found")
}
context.put('fileList', fileList)

def f = new File("C:\\Users\\Documents\\Groovy Scripts\\requests\\${context.fileList}.last().text")
log.info f

Update based on comments, adding to the question.

My test case contains 3 steps. Step 1: to read the xml file from the folder. Step 2: use the xml file content as soap request input. Step 3: save the response of step 2 in output folder as xml.

It is understand that you need to do the data-driven tests where requests are kept in a directory.

Previously, an approach is provided here to loop thru the data and save responses.

All the change you might need now is in the very first step - which reads the directory, and loops thru your files and set the file content as request and run the soap request step.

Groovy Script for Step1:

import groovy.io.FileType

//change your input directory name below
def dir = new File('path/to/input/dir')
dir.eachFile (FileType.FILES) { file ->  

   //Get the step
   def step = context.testCase.getTestStepAt(1)
   //Set the file content as test step request
   step.testRequest.requestContent = file.text
   log.info "New request is set for step2 : ${request}"
   //Run the step2
   step.run(testRunner, context)
}
//By now all the orders got executed, now need to exit the step without additionally running step2
//So, jump to step2, index is 2
testRunner.gotoStep(2)
