Claude Code coverage-plan for EF Core extension tests

Map tests to source and prioritize missing public API, complex behavior, and edge case coverage.

Install in Claude Code

Open the CmdScale TimescaleDB extension in Claude Code with the test-coverage-planner project agent and the existing tests.

Review `.claude/skills/coverage-plan/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.claude/skills/coverage-plan/` in your project and save the reviewed file as `.claude/skills/coverage-plan/SKILL.md`.
Start Claude Code from that project's root, then select `/coverage-plan` in the slash menu.

Example task

In cover-18, a public configuration method already has a valid-input test. The rejection branch for {retentionDays: 0, allowed: false} has no test.

What to check

Prioritize the missing public API rejection case {retentionDays: 0, allowed: false}. Note whether a unit test covers it or if a real database integration is needed.

Frequently asked question

Does it write tests directly?

This step returns a testing strategy that a test-writing workflow can implement. It can distinguish unit tests from integration tests that need Testcontainers.
