Specifying global document overrides for tests?

[johnrengelman]

I have a situation where I have a project that generates a bundle and in that bundle I want to include a skeleton data document (using data.json file in the root) that will be patched at runtime by a bundle service. The difficulty I'm running into is what to do with the local test fixtures.
I can't put them into data.json as they would be bundled in and I want to avoid that.
Specifying them in each test rule is cumbersome and would be very repetitious. So that leaves me with 2 options:

1. Put the test fixtures into directories (eg applications/data.json) that map to each top-level document. Downside, is that I have to make sure if any developer adds a top-level document, that they update the opa build command to add --ignore <path> so that it isn't included in the bundle.
2. Put the data into a single folder (eg fixtures/data.json). Downside is that each test rule has to specify a with data.applications as data.fixtures.applications which is very repetitious.

Ideally, if I could specify a global document override to the opa test command, I could avoid this situation Or, better yet, if there was a special path that was always automatically remapped only under opa test. So fixtures/applications/data.json would be automatically mapped to data.applications instead of data.fixtures.applications.

(coming from a java background, this is similar to how src/test/resources will override anything in src/main/resources in standard project formats.

Would a feature like this be something that would be considered? Any other alternatives?

Maybe I'm missing something but what is the need to include tests in your final bundle? I would imagine you test all your rules and then build the bundle w/o tests in it.

Not sure you'd need that. If you run the tests without the --bundle flag, like:

opa test bundle/ fixtures/

you could just have a data.json file in the fixtures dir where the path was provided in the file rather than by directory structure, e.g.

{
  "applications": {
    "...": "..."
  }
}

Ah, that's what I was missing. Specifying an additional path, puts it on the root of the tests.
Thanks @anderseknert
