Stuck on an issue?

Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.

And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

Reproducibility of results broken between Faker-0.7.18 and (Faker-0.8.0, 0.8.7)

See original GitHub issue

Faker-0.8.0 and Faker-0.7.18 generate different values when given the same random source.

Is the deterministic generation a goal of the project or not? I assumed that it is before… because the README specifically says that it’s useful for unit testing, which is how I use it.

I think it’s fine to use semver, just add a notice that the data inside the providers is subject to change between versions, and that the only guarantee of reproducibility is when using the same faker version.

@sp-1234 Since we keep updating data in the providers pretty much at every release, we’ll keep breaking the reproducibility at every release.

Maybe we should just stop using semver entirely and switch to date-based versioning.
