Pros

  • helps very fast to cover complex test cases
  • saves a lot of typing (generally worth to test generated structures)

Cons

  • renaming of files, functions or describes leads to changes that are hard to verify
    • snapshots with old names are deprecated
    • snapshots with new names are generated
    • you don't have a diff between the two
  • first run of the tests generates snapshot, so it's impossible to do red-green-refactor properly
    • you can fake it out by saving first snapshot empty, but you have to think about it
