ReqCassette v0.3.0 – Safer Recording & Better Filtering

What’s New

Safer :record mode (breaking change)

• Fixed dangerous behavior where multi-request tests would lose interactions
• Simplified API: 4 recording modes → 3
• Migration: just replace :record_missing with :record

Better filtering

• New filter_request and filter_response options
• Comprehensive filtering guide for protecting API keys

Quick Example

with_cassette "api_test",
  [filter_request_headers: ["authorization"]],
  fn plug ->
    Req.get!("https://api.example.com", plug: plug)
  end
