arrays - Conditional Json Schema validation based on property value -

i have input json below,

{   "results": [     {       "name": "a",       "testa": "testavalue"     }   ] } 

the condition is, if value of 'name' 'a', 'testa' should required field , if value of 'name' 'b', 'testb' should required field.

this json schema tried , not working expected,

{   "$schema": "http://json-schema.org/draft-04/schema#",   "type": "object",   "required": [     "results"   ],   "properties": {     "results": {       "type": "array",       "oneof": [         {           "$ref": "#/definitions/person"         },         {           "$ref": "#/definitions/company"         }       ]     }   },   "definitions": {     "person": {       "type": "object",       "required": [         "name",         "testa"       ],       "properties": {         "name": {           "type": "string",           "enum": [             "a"           ]         },         "testa": {           "type": "string"         }       }     },     "company": {       "type": "object",       "required": [         "name",         "testb"       ],       "properties": {         "name": {           "type": "string",           "enum": [             "b"           ]         },         "testb": {           "type": "string"         }       }     }   } } 

tried "dependecies" in json schema wasn't able find correct solution.

any / workaround sample json schema achieve above use case appreciated.

your're close. oneof needs in items keyword.

{     "type": "array",     "items": {         "oneof": [             { "$ref": "#/definitions/person" },             { "$ref": "#/definitions/company" }         ]     } }
