Playing with it I discovered a couple cool pytest plugins
- pytest-deepassert - Enhanced pytest assertions with detailed diffs powered by DeepDiff
  - cool readable diffs of deep data structures
- pytest-plus - some extended pytest functionality
  - I like the “Avoiding duplicate test function names” and “Avoiding problematic test identifiers” features
