Unexpected HTTP Server Testing Plugin

unexpected-http is a plugin for the `unexpected` assertion library, specifically designed for testing HTTP servers and clients. It extends `unexpected`'s declarative syntax, allowing developers to write expressive assertions against HTTP requests and responses, mimicking the style of `unexpected-express`. As of version 9.0.0, it supports `unexpected` versions 10 through 13. The library enables fluent testing of server-side applications by asserting on status codes, headers, and body content of HTTP interactions. While its release cadence often aligns with its core `unexpected` dependency, it receives updates to maintain compatibility and introduce features relevant to HTTP testing. Its primary differentiator is its deep integration into the `unexpected` ecosystem, providing a consistent assertion experience across various testing scenarios, including frontend, backend, and API testing, by leveraging `unexpected`'s powerful diffing and introspection capabilities for failed assertions.
