What code coverage should I target?

80% for business logic is a good target. 100% coverage is rarely worth the cost. Focus on testing critical paths and complex logic rather than chasing a coverage number.

What tools do you use for testing?

Vitest or Jest for unit tests, Supertest for API integration tests, and Playwright or Cypress for e2e tests. The choice depends on the project stack.

Automated Testing Explained

Unit tests, integration tests, and e2e tests that run on every commit — catching regressions before they reach users.

Automated Testing

The practice of using software tools to execute pre-scripted tests on an application automatically, verifying that code behaves as expected without manual intervention.

Explanation

Automated testing includes multiple levels: unit tests (testing individual functions), integration tests (testing component interactions), and end-to-end tests (testing full user workflows). Automated tests run in CI pipelines on every code change, catching regressions before they reach production. A well-designed test suite runs in minutes and provides confidence that changes do not break existing functionality. The testing pyramid suggests having many unit tests, fewer integration tests, and even fewer e2e tests.

Bookuvai Implementation

Every Bookuvai project includes automated testing as a non-negotiable quality standard. We target 80%+ code coverage for business logic, write integration tests for every API endpoint, and include critical-path e2e tests. Tests run in CI on every pull request, and the AI PM tracks coverage trends.
