Hypothesis strategies for GraphQL schemas, queries and data.

NOTE This package is experimental, some features are not supported yet.

There are two strategies for different use cases.

1. Schema generation - hypothesis_graphql.strategies.schema()
2. Query - hypothesis_graphql.strategies.query(schema).

Lets take this schema as an example:

type Book {
  title: String
  author: Author
}

type Author {
  name: String
  books: [Book]
}

type Query {
  getBooks: [Book]
  getAuthors: [Author]
}

Then strategies might be used in this way:

from hypothesis import given
from hypothesis_graphql import strategies as gql_st

SCHEMA = "..."  # the one above

@given(query=gql_st.query(SCHEMA))
def test_query(query):
    ...
    # This query might be generated:
    #
    # query {
    #   getBooks {
    #     title
    #   }
    # }
