SuperDiff is a Ruby gem that provides an intelligent diff engine for comparing complex data structures in RSpec tests. It replaces RSpec's default string-based diffing with readable, structured output showing exactly what differs between objects like hashes, arrays, and custom objects.
Use cases
- readable diffs for complex data structures in RSpec tests
- compare nested hashes and arrays in test failures
- improve RSpec eq/match/include matcher output
- diff API response data in specs
- diff database records and custom objects in tests
When to choose
- you use RSpec and struggle to interpret default diff output for hashes, arrays, or objects
- your tests compare nested API or database data structures
- you want color-coded, line-by-line insight into test failures
When to avoid
- you don't use RSpec or Ruby
- you only diff simple multi-line strings, where built-in RSpec diffing suffices
- you need diffs outside a testing context
