Test coverage for your riskiest code

Cover the riskiest paths first

Coverage reports show the gaps. Nobody has time to close them. Agents rank untested code by business risk, write tests in your style, and run them green before your refactor or your audit.

Riskiest first

Review and reorder the risk-based test plan

Chasing a coverage number wastes tests on getters. The planner ranks files by how often they change and how little is tested, then proposes a plan your QA lead can reorder before a single test is written.

01Tax rounding across 12 regions

02Refund after a partial payment

03Invoice totals with credits applied

04Proration on mid-cycle plan change

Tests that look like yours

New tests follow your team’s existing conventions

Agents read your existing tests first: the framework, the fixtures, how you name things, what you assert. New tests follow the same conventions, so they get maintained instead of deleted.

invoices.spec.tsWritten by your team, 2023

describe('InvoiceTotals', () => { const inv = buildInvoice({ lines: 3 })1 it('applies credit before tax', () => {2 expect(totals(inv).due) .toBeCloseTo(84.15, 2)3 })})

describe('Refunds', () => { const inv = buildInvoice({ paid: 0.5 })1 it('refunds only the paid share', () => {2 expect(refund(inv, 100).amount) .toBeCloseTo(50.00, 2)3 })})

For the audit

Coverage history you can hand an auditor

Every run records coverage before and after, per module, with the approved plan and the passing suite attached. Export it when the auditor asks, instead of rebuilding it from memory.

Frequently asked questions

Which code do agents add test coverage to first?

Agents rank untested code by business risk, using churn, complexity, and incidents, and start with the code most likely to break. You approve the spec, including the cases to test, before any tests are written.

Will the new tests match our existing ones?

Yes. Agents read your existing tests first, including the framework, fixtures, naming, and assertions, then write unit, integration, and end-to-end tests that follow the same conventions.

Do test coverage pull requests change application code?

No. Tests land as test-only pull requests, grouped by behavior, with the cases listed in plain language. They pass in an isolated sandbox before the pull request opens.

What record do I get for an audit?

Every run records coverage before and after, per module, with the approved plan and the passing suite attached, ready to export when the auditor asks.
