Support multiple tuple files in tests

[xtsee]

Scope Allowing multiple tuple files gives you the option to break up your fixtures data (tuples) and reuse them across different tests. For example, you might have a set of tuples that contain all companies and another set of tuples for teams. This should make managing the test data a lot easier.

Example

tests: # required
  - name: test-1
    # tuple_file: ./tuples.yaml # tuples that would apply per test
    # tuple_file: # or multiple
    #   - ./tuples-1.yaml
    #   - ./tuples-2.yaml

Bump on this use case. I have a set of initial tuples to set up global relationships between models. I want to source the initial tuples as an external file and then supply the test tuples in the YAML.

Update - looking through the source code, I found out you can add tuple_files directly on the test. These will be merged with the tuples at the root of the test file:

name: Auditor
model_file: './model.fga'
tuples:
  - user: employee:sbird
    relation: member
    object: auditor:global
  - user: employee:mrapinoe
    relation: member
    object: admin:global
  - user: admin:global#member
    relation: owner
    object: namespace:foo
  - user: auditor:global#member
    relation: observer
    object: namespace:foo
tests:
  - name: "direct relation to auditor:global"
    tuple_file: './initial_tuples.json'
    check:
    - user: employee:sbird
      object: auditor:global
      assertions:
        member: true
  - name: "admin is an auditor"
    tuple_file: './initial_tuples.json'
    check:
    - user: employee:mrapinoe
      object: auditor:global
      assertions:
        member: true
  - name: "global auditor is a workflow observer"
    tuple_file: './initial_tuples.json'
    check:
    - user: employee:sbird
      object: namespace:foo
      assertions:
        observer: true
