Fix broken tests

JaniAnttonen opened this issue · comments

commented

There's a bunch of tests that don't work, mostly because the fixtures in ./test/fixtures.json are invalid. This is because there's less data processing happening in 6.0.0 before sending than before. Logs in this version only get formatted and stringified just before sending out for easier processing.

Step 2: ⌨️ Coding

Modify ./test/fixtures.json with contents:
• Update the structure of log entries in `fixtures.json` to reflect the simplified log formatting and stringification process introduced in winston-loki 6.0.0-rc.1. This includes adjusting the `logs`, `logs_mapped_before`, and `logs_mapped_after` arrays to match the expected format just before sending to Grafana Loki.
• Ensure that the `incorrect_mapping` entry is updated or removed based on its relevance to the new processing logic.
