httpexpect
A concise, declarative Go library for end-to-end HTTP and REST API testing with chainable request builders and assertions.
What is httpexpect?
httpexpect is a Go testing library for end-to-end HTTP and REST API testing. It provides a fluent, chainable interface for building HTTP requests and making assertions on responses, making API tests more readable and maintainable. The library supports testing via real HTTP clients or by directly invoking HTTP handlers, and includes features like WebSocket testing, JSON Schema validation, and detailed error reporting.
Go developers writing integration or end-to-end tests for HTTP servers, REST APIs, and WebSocket services. It is particularly useful for teams needing expressive, declarative test syntax that integrates with Go's standard testing tools.
Developers choose httpexpect for its comprehensive feature set, including WebSocket support, JSONPath queries, and JSON Schema validation, combined with a fluent API that improves test readability. Its flexibility in testing approaches—via real HTTP or direct handler invocation—and detailed, configurable error output make it stand out from simpler assertion libraries.
