Hi,
Not sure how you are doing.
Here is possible way assuming that 5 xml to be requested on after other sequencially.
Create a TestCase as following:
1. groovy script step with following code(this setting a project level properties, you may change it to test case level if you need)
testRunner.testCase.testSuite.project.setPropertyValue("UNIQUEID_1", System.currentTimeMillis().toString())
testRunner.testCase.testSuite.project.setPropertyValue("UNIQUEID_2", System.currentTimeMillis().toString())
testRunner.testCase.testSuite.project.setPropertyValue("UNIQUEID_3", System.currentTimeMillis().toString())
testRunner.testCase.testSuite.project.setPropertyValue("UNIQUEID_4", System.currentTimeMillis().toString())
testRunner.testCase.testSuite.project.setPropertyValue("UNIQUEID_5", System.currentTimeMillis().toString())
2. Define 5 request steps. In each request, use the above id instead of a constant element value with ${#Project#UNIQUEID_#} , replace # value 1..5 in each request.
Now you can try running TestCase, and see you are achieving what is required.
Then define a load test, and run for 100 times.
Hope this helps.
