SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the creation of robust testing infrastructure for eBPF-based Cloud-Native Functions (CNFs), ensuring their reliability and performance.

Core Features & Use Cases

  • Test Infrastructure Generation: Sets up network namespaces, virtual interfaces, and traffic generation tools.
  • Validation: Verifies eBPF map operations, event generation, and packet processing logic.
  • Use Case: When developing a new eBPF-based network filter for a CNF, use this Skill to automatically generate a comprehensive test suite that validates packet drop/forwarding logic under various traffic conditions.

Quick Start

Use the ebpf-test-harness skill to generate unit tests for validating eBPF map operations.

Frequently Asked Questions about ebpf-test-harness

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate eBPF CNF testing for packet processing logic?▼

To automate eBPF CNF testing, you can generate test infrastructure that sets up network namespaces, creates virtual interfaces, and injects traffic to validate packet forwarding or dropping logic under various conditions.

What is the best way to validate eBPF map operations in a CNF?▼

Validating eBPF map operations involves generating automated unit tests that interact with your eBPF programs to verify state changes, event generation, and data retrieval within the CNF environment.

Do I need Go to set up a test harness for eBPF network functions?▼

Yes, you need the Go programming language and specific libraries for network manipulation and eBPF interaction to generate and run the test infrastructure for your Cloud-Native Network Functions.

Can I generate traffic to test an eBPF network filter in isolated namespaces?▼

Yes, you can generate traffic by setting up isolated network namespaces and virtual interfaces, allowing you to safely inject packets and verify the processing logic of your eBPF network filter.

Why does my eBPF CNF test suite fail to verify event generation?▼

Test suites may fail to verify event generation if the automated test infrastructure lacks proper virtual interface configuration or traffic generation setup required to trigger the eBPF program events.

Does ebpf-test-harness support automated testing for Cloud-Native Functions?▼

The ebpf-test-harness specifically supports automated testing for Cloud-Native Functions by generating comprehensive test suites that validate packet processing, map operations, and event generation.
