Commonly assumed

A common v1-era expectation is that rescuing `Faraday::Error::ClientError` is still valid in Faraday 2.

The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.

Contract

• assert !Faraday::Error.const_defined?(:ClientError, false)
• assert_raise NameError when resolving Faraday::Error::ClientError
• assert Faraday::ClientError < Faraday::Error

Files

• Gemfile
• NOTES.md
• csx.json
• test/contract.rb
