oneOf matcher does not work for property with data types string | empty (“”) | null

[asub927]

I need to validate an api which has a response property which returns string or empty or null values based on the data in the backend.

• Initially tried with string() matcher which fails when the property value returns empty or null
• then tried oneOf() matcher which also fails when the property value returns string()
• works when I use any() but I want to match specific to the allowed data types

Code sample for reference. Any help to handle this condition is greatly appreciated.

_spec
.get(/api)
.expectStatus(200)
.expectJsonMatch({
property: oneOf([string(), "", null])}

With the current implementation of oneOf, it only supports strings. Ex:

{ "gender": oneOf(["male", "female"]) }

Marking this as a feature request.

For a workaround, please use expression matcher.
