truefix-at

Maintainer-facing black-box acceptance suite for the TrueFix FIX engine. It starts a real truefix-transport acceptor, drives scripted client steps, and reports each scenario/version run. Applications normally do not depend on this crate.

Independent use

Yes, this crate can be used independently to embed TrueFix black-box scenarios in a maintainer or downstream compatibility test suite. It is not needed by production FIX applications.

Public surface

The crate exports Scenario, Step, ExpectMsg, ScenarioResult, run_scenario, run_report, and start_acceptor. Scenarios cover framing, session behavior, dictionaries, configuration, and transport behavior across the versions declared by each scenario.

Verify

cargo test -p truefix-at
cargo test -p truefix-at --test conformance
