Swagger-Dredd: specifying more than one type for a parameter

I am trying to implement API testing in my project and i am using Dredd. Now some of my response parameters return 'null' value and that is okay according to logic. In my yml file, how do i specify that null can be a valid value apart from the normal expected value, say, string.

cdeOutageUpdateType: {type: string}, txtDesc: {type: string},

In the above parameter, it is okay if cdeOutageUpdateType is empty. But my Dredd test fails because of it.

body: At '/19/cdeOutageType' Invalid type: null (expected string)

Solution

  • I found out the solution for this situation. Swagger specification can be modified with an attribute "x-nullable"

    cdeOutageUpdateType: {type: string, x-nullable: true}, txtDesc: {type: string},

    The above will ignore cdeOutageUpdateType if it is null.
