Improve system test coverage and practices for KubeArmor

[DelusionalOptimist]

Description

Currently our Ginkgo based test suite for running system tests is lacking behind. We are not testing all of KubeArmor's features in different important supported environments.

Goals

The main goals of this are going to be as given below, please see attached issues for more details

• Calculate code coverage in CI - CI Test Coverage Calculation #845
• Add test suite for host protection capabilities of KubeArmor in Kubernetes and Non-Kubernetes mode - CI(tests): ginkgo tests for host security capabilities of KubeArmor #1625
• Extend existing container protection test suite to Non-Kubernetes mode
• Test on ARM based machines - Automated Tests for BPF LSM, Unorchestrated Workloads and ARM #1228
• Automate running post-release tests for certain, frequently used environments - v1.3.1 release checklist #1675
• Improvise the existing test suites -
  • Reduce completion time (30 minutes for each enforcer/runtime currently)
    • Using a common workflow for building images
    • Only build the component which actually changed
  • Reduce flakiness
  • Suggestions welcome...
• Improve docs on writing tests

Extended Goals (to be pursued only if enough time left)

• Understand and implement fuzz testing in context of KubeArmor (any one of the modules)

Test Matrix Tracker

Provider	Environment	Type	AppArmor	BPF LSM	Arch	Runtime	Frequency
Onprem	k3s	Kubernetes	Container ✔️, Host ❌	Container ✔️, Host ❌	amd64 ✔️, arm ❌	Docker ✔️ , Containerd ✔️, CRI-O ✔️,	Push, PRs, Release
Linux	Ubuntu, Fedora	Non-k8s	Container ❌, Host ❌	Container ❌, Host ❌	amd64 ❌	Docker ❌ , Systemd ❌	Push, PRs, Release
Onprem	KinD/Minikube, kubeadm	Kubernetes	Container ❌, Host ❌	Container ❌, Host ❌	amd64 ❌	Virtualbox ❌, Containerd ❌	Release
Managed	TBD	Kubernetes	Container ❌, Host ❌	Container ❌, Host ❌	amd64 ❌ arm64 ❌	TBD	Release

NOTES

• Non-k8s test suite would work with both KubeArmor running in container mode as well as systemd mode.
• For each of the above testing of the below aspects will be considered to mark it as complete
  • Observability
  • Enforcement
  • Alerts

Prerequisite Task

Create at least one new and unique test case for KubeArmor (can be in any mode) using the ginkgo framework and show the total improvement in coverage. The test coverage tool doesn't have to be run as part of the CI.

Deadline - 31 May 2024 11:59 PM UTC

Please don't share your task solutions publicly, prefer e-mailing a link to your fork/branch to mentors.
