Issue/Introduction

The VS has all of below request data as arguments in VSI and during playback getting a META match (which has Match Style=Operation) instead of a specific match because of the null values for DateIn and DateOut.

The JSON request with null values for the data are captured during recording and playback and causing issue in 10.8.4.

{
  "Name": "Test",
  "Number": "1234.123",
  "DateIn": null,
  "DateOut": null,
  "Guests": 2,
  "radius": "80",
  "desc": "Reservation"

}

 For example, the above JSON request is parsed with different arguments as below in different versions.

In 10.7.2:

{
  "Name": "Test",
  "Number": "1234.123",
  "Guests": 2,
  "radius": "80",
  "desc": "Reservation"

}

 

In 10.8.4:

{
  "Name": "Test",
  "Number": "1234.123",
  "DateIn": null,
  "DateOut": null,
  "Guests": 2,
  "radius": "80",
  "desc": "Reservation"

}

It appears null/optional data are getting added during transformation by the DevTest framework itself. This is impacting both record & playback features.

Environment

DevTest 10.8.4

Cause

The request to parse all arguments including the one's have null values are implemented in the latest versions of DevTest. With the change, now DateIn & DateOut arguments are parsed and showing during and in playback in VSE-->Inspection View.

Resolution

If the JSON request doesn't need to parse the null values, please open a support case and ask for patch patch_DE646815_10.8.4_GA.jar.
