What problem does it solve?

This Skill helps charm developers update their unit tests from the deprecated ops.testing.Harness framework to the modern, event-driven state-transition tests, ensuring compatibility with current Juju releases.

Core Features & Use Cases

  • Harness Detection: Identifies all usages of ops.testing.Harness and related helpers within your test suite.
  • Guided Migration: Provides step-by-step instructions and recipes for rewriting tests to model Juju events and states accurately.
  • Use Case: You have a charm with many unit tests still using Harness. This Skill will guide you through systematically replacing them with state-transition tests, ensuring your charm's test suite remains functional and maintainable.
