test-coverage

To increase test coverage to 90%, this Skill automates iterative test generation and refactoring by analyzing a target code zone to identify untested paths, continuously generating and executing tests until the threshold is achieved.

Automating unit test generation for untested branches is best handled by analyzing the target area and delegating execution to a test-runner subagent. This approach iteratively generates, runs, and refactors tests to ensure deterministic results and expand coverage.

Yes, you can use Jest to reach a 90% coverage threshold. This Skill requires coverage measurement tooling like Jest or PNPM to orchestrate test creation, measure results, and guide the iterative refactoring needed to cover edge cases.

You can generate tests from a Jira ticket by providing the ticket or local path as scope input. The Skill analyzes the specified work item, targets the relevant local code zone, and initiates the automated testing loop to cover untested paths.

Yes, a deterministic test runner is required to automate code coverage expansion. The Skill delegates test execution to this subagent to ensure consistent, deterministic results across multiple iterative test runs during the refactoring loop.

Iterative test generation stops before reaching the 90% coverage target when untested paths cannot be resolved without further code refactoring. The loop measures, refactors, and extends tests, but complex edge cases may require manual intervention to achieve deterministic results.
