It allows for very quick and +iterative development cycles, and supports several platforms. + +To run the test suite on your current platform in QEMU: + + $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc) + +To run it with KASAN and such turned on: + + $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc) + +To run it emulated for another platform in QEMU: + + $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc) + +At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k, +mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64. + +The system supports incremental rebuilding, so it should be very fast to +change a single file and then test it out and have immediate feedback. + +This requires for the right toolchain and qemu to be installed prior. +I've had success with those from musl.cc. + +This is tailored for WireGuard at the moment, though later projects +might generalize it for other network testing. + +Signed-off-by: Jason A.
