Automating test creation and execution for Next.js apps involves planning test scope, writing Vitest unit/integration tests and Playwright E2E tests, executing them, and applying automated fixes to failures.

Fixing failing tests and enforcing linting during CI is achieved by running automated workflows that execute tests, validate results with regression checks, and apply auto-fixes to ensure code passes linting.

To mock external services when writing integration tests, you should use a mandatory planning phase to analyze the test scope, identify dependencies, and generate a robust test plan that mocks external services before execution.

Yes, this automated testing workflow supports both Vitest for unit and integration tests, and Playwright for end-to-end tests, allowing comprehensive coverage across different testing levels in Next.js applications.

A planning phase is required before writing and running tests to analyze the scope, mock dependencies, and generate a robust test plan, ensuring that the tests effectively verify features and prevent regressions.

To generate test coverage reporting and validate regression checks, execute your Vitest and Playwright tests through an automated workflow that validates results, enforces linting, and produces coverage reports to prevent regressions.
