dev-flaky 0.9.1

Flaky test detection for Rust. Runs cargo test N times and classifies each test as stable / flaky / broken with a reliability score in [0.0, 1.0]. Part of the dev-* verification collection.
Documentation
//! Run the test suite a few times and print the resulting `Report`.
//!
//! ```text
//! cargo run --example basic
//! ```
//!
//! **Important:** invoking this from inside `cargo test` (or from a
//! working directory where another `cargo` invocation already holds
//! the target-dir lock) will deadlock. Run it from a checkout of the
//! crate you actually want to scan for flakiness, e.g.:
//!
//! ```text
//! cd /path/to/your-crate
//! CARGO_TARGET_DIR=/tmp/flaky-target cargo run --manifest-path /path/to/dev-flaky/Cargo.toml --example basic
//! ```
