Runt is a lightweight, parallel snapshot testing framework. It aims to enable snapshot testing with minimal configuration.
Runt is most useful when you have the following test setup: - One command that needs to run on many input files. - Test suites grouped by commands run on the files. - Test outputs are sent to IO streams (stdout and stderr).
Runt is not useful when you want to do: - Rich introspective testing of data structures. - Test suites with complex setups, dependencies, and teardowns.
cargo build --release. The runt executable is generated
under target/release/runt.runt.toml
file contains all the configuration and explanation for various options.
