Aya Regression Tests

The aya regression test suite is a set of tests to ensure that common usage behaviours work on real Linux distros

Prerequisites

This assumes you have a working Rust and Go toolchain on the host machine

1. rustup target add x86_64-unknown-linux-musl
2. Install rtf: go install github.com/linuxkit/rtf@latest
3. Install rust-script: cargo install rust-script
4. Install qemu and cloud-init-utils package - or any package that provides cloud-localds

It is not required, but the tests run significantly faster if you use sccache

You may also use the docker image to run the tests:

docker run -it --rm --device /dev/kvm -v/home/dave/dev/aya-rs/aya:/src -w /src/test ghcr.io/aya-rs/aya-test-rtf:main

Usage

To read more about how to use rtf, see the documentation

Run the tests with verbose output

rtf -vvv run

Run the tests using an older kernel

AYA_TEST_IMAGE=centos8 rtf -vvv run

Writing a test

Tests should follow this pattern:

• The eBPF code should be in a file named ${NAME}.ebpf.rs
• The userspace code should be in a file named ${NAME}.rs
• The userspace program should make assertions and exit with a non-zero return code to signal failure
• VM start and stop is handled by the framework
• Any files copied to the VM should be cleaned up afterwards

See ./cases for examples
