clap-validator

A validator and automatic test suite for CLAP plugins. Clap-validator can automatically test one or more plugins for common bugs and incorrect behavior.

Download

Prebuilt binaries can be found on the releases page. Development builds can be found here. The macOS builds are unsigned and may require Gatekeeper to be disabled or the quarantine bit to be removed (instructions).

Usage

Simply pass the path to one or more .clap plugins to clap-validator validate to run the validator on those plugins. The --only-failed option can be used to hide the output from all successful and skipped tests. Running clap-validator validate --help lists all available options:

clap-validator validate /path/to/the/plugin.clap
clap-validator validate /path/to/the/plugin.clap --only-failed
clap-validator validate --help

Debugging

clap-validator runs tests in separate processes by default so plugin crashes can be treated as such instead of taking down the validator. If you want to attach a debugger to debug the plugin's behavior during a specific test, you can tell the validator to run the that test in the current process. Use clap-validator list tests to list all available tests.

clap-validator validate --in-process --test-filter <test-case-name> /path/to/the/plugin.clap

Building

After installing Rust, you can compile and run clap-validator as follows:

cargo run --release -- validate /path/to/the/plugin.clap
