Using payload type as Map throws compile time error

[shashank singh]

Hi All

My spec json looks like this 

{

  "tests": {

    "trendTest": {

      "buckets": {

        "control": 0,

        "experimental": 1

      },

      "fallbackValue": 0,

      "payload": {

      "type": "map"                                // working for type = stringValue

      }

    }

  }

}

Ran - mvn proctor:generate -e  

[ERROR] Failed to execute goal com.indeed:proctor-maven-plugin:1.1.39:generate (default-cli) on project core: Execution default-cli of goal com.indeed:proctor-maven-plugin:1.1.39:generate failed. NullPointerException -> [Help 1]

Basically for my buckets I plan to have have payload as json object basically using map type.

Also how it should look in bucket

"buckets": [

    {

      "name": "control",

      "value": 0,

      "description": "default behavior",

      "payload": {

        "stringValue": "controlPayload"        // how to use map here ?

      }

    }

  ]

dependency pom - 

proctor-common        : 1.1.39

proctor-consumer      : 1.1.39

proctor-codegen       : 1.1.39

proctor-maven-plugin  : 1.1.38

Hi, shashank.

Thanks for reaching out to us!

If you want to use map payload type, please specify a schema of a payload you are going to use in specification json file.

This is a example of specification file.

 {
  "tests": {
    "trendTest": {
      "buckets": {
        "control": 0,
        "experimental": 1
      },
      "fallbackValue": 0,
      "payload": {

        "type": "map",
        "schema": {
          "fieldname1" : "stringValue",
          "fieldname2" : "stringValue"
        }
      },
    }
  }
}

Then, you can describe a content of payloads with the specification in test matrix file as follows

"buckets": [
    {
        "name": "control",
        "value": 0,
        "description": "default behavior",
        "payload" : {

            "map" : {
                "fieldname1": "controlPayload",
                "fieldname2": "value2",
            }
        }
    }
]

If you want to see more example of specification and proctor matrix with map payload type, proctor-codegen-test module might be useful.
