This folder contains the Regression tests suite for Falco.

You can find instructions on how to run this test suite on the Falco website here.

• falco_tests
• falco_traces
• falco_tests_package
• falco_k8s_audit_tests
• falco_tests_psp

This step assumes you already built Falco.

Note that the tests are intended to be run against a release build of Falco, at the moment.

Also, it assumes you prepared falco_traces (see the section below) and you already run the following command from the build directory:

make test-trace-files

It prepares the fixtures (json and scap files) needed by the integration tests.

Requirements

• Python 3.x
• Virtualenv
• grpcurl

Setup and execution

Using virtualenv the steps to locally run a specific test suite are the following ones (from this directory):

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
BUILD_DIR="../build" avocado run --mux-yaml falco_tests.yaml --job-results-dir /tmp/job-results -- falco_test.py
deactivate

The name of the specific test suite to run is falco_tests.yaml in this case. Change it to run others test suites.

In case you want to only execute a specific test case, use the --mux-filter-only parameter as follows:

BUILD_DIR="../build" avocado run --mux-yaml falco_tests.yaml --job-results-dir /tmp/job-results --mux-filter-only /run/trace_files/program_output -- falco_test.py

To obtain the path of all the available variants for a given test suite, execute:

avocado variants --mux-yaml falco_tests.yaml

The falco_traces.yaml test suite gets generated through the falco_traces.yaml.in file and some fixtures (scap files) downloaded from the web at execution time.

1. Ensure you have unzip and xargs utilities

2. Prepare the test suite with the following command:

   bash run_regression_tests.sh -p -v

The falco_tests_package.yaml test suite requires some additional setup steps to be succesfully run on your local machine.

In particular, it requires some runners (ie., docker images) to be already built and present into your local machine.

1. Ensure you have docker up and running

2. Ensure you build Falco (with bundled deps)

   The recommended way of doing it by running the falcosecurity/falco-builder docker image from the project root:

   docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder cmake
   docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder falco

3. Ensure you build the Falco packages from the Falco above:

   docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder package

4. Ensure you build the runners:

   FALCO_VERSION=$(./mybuild/release/userspace/falco/falco --version  | head -n 1 | cut -d' ' -f3 | tr -d '\r')
   mkdir -p /tmp/runners-rootfs
   cp -R ./test/rules /tmp/runners-rootfs
   cp -R ./test/trace_files /tmp/runners-rootfs
   cp ./mybuild/release/falco-${FALCO_VERSION}-x86_64.{deb,rpm,tar.gz} /tmp/runners-rootfs
   docker build -f docker/tester/root/runners/deb.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-deb /tmp/runners-rootfs
   docker build -f docker/tester/root/runners/rpm.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-rpm /tmp/runners-rootfs
   docker build -f docker/tester/root/runners/tar.gz.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-tar.gz /tmp/runners-rootfs

5. Run the falco_tests_package.yaml test suite from the test directory

   cd test
   BUILD_DIR="../mybuild" avocado run --mux-yaml falco_tests_package.yaml --job-results-dir /tmp/job-results -- falco_test.py

In case you want to run all the test suites at once, you can directly use the run_regression_tests.sh runner script.

cd test
./run_regression_tests.sh -v

Just make sure you followed all the previous setup steps.
