## What it is
Transpec is a command-line tool that automatically converts RSpec test code to the latest RSpec syntax using static and dynamic code analysis. It is officially recommended by the RSpec team for upgrading RSpec 2 specs to RSpec 3.

## Use cases
- convert rspec should syntax to expect syntax
- upgrade rspec 2 specs to rspec 3
- automatically migrate test suite to modern rspec
- convert stub and mock syntax in ruby specs
- bulk rewrite spec files preserving code style

## When to choose
- you are upgrading a Ruby project from RSpec 2 to RSpec 3
- you have a large spec suite using the old should/stub syntax
- you want syntax conversion that preserves formatting and honors your code style

## When to avoid
- your project already uses modern RSpec 3+ expect syntax
- you need a general-purpose Ruby refactoring tool rather than RSpec-specific conversion
- you need actively developed tooling for the newest RSpec versions
