## Description
|
|
|
|
Test fixtures use non-deterministic random values, which can make test failures harder to reproduce:
|
|
|
|
- `test/support/fixtures/music_library/records.ex:74` — `Enum.random(@artists)`
|
|
- `test/support/fixtures/music_library/records.ex:86` — `Enum.take_random(@genres, :rand.uniform(3))`
|
|
- `test/support/fixtures/music_library/records.ex:91` — `Enum.random(@titles)`
|
|
- `test/support/fixtures/music_library/records.ex:93` — `Enum.random(Record.formats())`
|
|
- `test/support/fixtures/music_library/records.ex:95` — `Enum.random(1969..2024)`
|
|
- `test/support/fixtures/scrobbled_tracks_fixtures.ex:16` — `Enum.random(0..86_400)`
|
|
|
|
Previously tracked in #85 (closed) but the randomness remains.
|
|
|
|
## Expected behavior
|
|
|
|
Use deterministic sequences (e.g., based on `System.unique_integer`) or seeded randomness for reproducible tests.
