Use Relative Path in model_file in Tests

[RichardWhitfield]

When defining the location of the model_file in a test yaml file, the expected behaviour is that the path to the model_file is relative to the test file where it is referenced but seems to be relative to the directory where the command originated.

For example: I have a folder structure as below:

• src
  • schema.fga
• tests
  • tests.yaml
  • data.yaml

In my tests.yaml file I define the location of the model_file as ../src/schema.fga.

If I execute this command:
fga model test --tests .\tests\tests.fga.yaml
from the root directory of the repo I get the below error:
Error: failed to read file ../src/schema.fga due to open ../src/schema.fga: The system cannot find the path specified.

If I execute the similar command:
fga model test --tests .\tests.fga.yaml then the command successfully executes.

Hi! I’m interested in taking on this issue. Can I go ahead and work on it?

Yes, I'm assigning it to you! Thanks!

Subject: Issue with CLI behavior – Unable to reproduce

Hi @aaguiarz ,

I’ve tested the issue by forking the repository, building and running the CLI as described.
After reproducing the steps in a clean environment, I found that the behavior
aligns with the expected output and the issue appears to be non-existent.

Here are the details I tested:

• downloaded your sample data with git clone https://github.com/openfga/sample-stores.git openfga-sample-stores
• reproduced the directory structure in the issue using your sample data (see below)

tree
.
├── src
│   ├── github.model.fga
│   └── model.fga
└── tests
    ├── github.store.fga.yaml
    └── store.fga.yaml

2 directories, 4 files

• renamed the location of model files as described in the issue, i.e. relative
  to the test file

grep "model_file" tests/store.fga.yaml
model_file: ../src/model.fga

grep "model_file" tests/github.store.fga.yaml
model_file: ../src/github.model.fga

• ran the command as described in the issue (ran multiple times from different locations
  showing only two different files as examples)

• first example of expected/desired behaviour (works)

fga model test --tests ./tests/store.fga.yaml
# Test Summary #
Tests 3/3 passing
Checks 6/6 passing
ListObjects 1/1 passing
ListUsers 1/1 passing

• second example of expected/desired behaviour (works)

fga model test --tests ./tests/github.store.fga.yaml
# Test Summary #
Tests 4/4 passing
Checks 6/6 passing
ListObjects 1/1 passing
ListUsers 3/3 passing

• undesired behaviour (get error as expected)

fga model test --tests ./store.fga.yaml
Error: failed to read file ./store.fga.yaml due to open ./store.fga.yaml: no such file or directory

Please let me know if I misunderstood the issue or perhaps
if there’s any additional context I should be aware of.

Best regards,

Denis
