Aya Integration Tests

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

Prerequisites

Linux

To run locally all you need is:

  1. Rust nightly
  2. libelf
  3. A checkout of libbpf
  4. cargo install bpf-linker
  5. bpftool

Other OSs

  1. A POSIX shell
  2. A checkout of libbpf
  3. rustup target add x86_64-unknown-linux-musl
  4. cargo install bpf-linker
  5. Install qemu and cloud-init-utils package - or any package that provides cloud-localds

Usage

From the root of this repository:

Native

cargo xtask integration-test --libbpf-dir /path/to/libbpf

Virtualized

./test/run.sh /path/to/libbpf

Writing a test

Tests should follow these guidelines:

  • Rust eBPF code should live in integration-ebpf/${NAME}.rs and included in integration-ebpf/Cargo.toml
  • C eBPF code should live in integration-test/src/bpf/${NAME}.bpf.c. It's automatically compiled and made available as ${OUT_DIR}/${NAME}.bpf.o.
  • Any bytecode should be included in the integration test binary using include_bytes_aligned!
  • Tests should be added to integration-test/src/test
  • You may add a new module, or use an existing one
  • Integration tests must use the #[integration_test] macro to be included in the build
  • Test functions should return anyhow::Result<()> since this allows the use of ? to return errors.
  • You may either panic! when an assertion fails or bail!. The former is preferred since the stack trace will point directly to the failed line.
