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 toolcahin 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

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
