runtime-verification

To verify development server readiness before running end-to-end tests, you can launch the server with configurable startup timeouts, validate health and readiness endpoints, and then execute your test suite automatically once the server is confirmed healthy and reachable.

Yes, you can run Playwright or Cypress smoke tests automatically in CI pipelines by discovering dev-server commands, starting the server, and executing browser-based checks to validate UI behavior and catch runtime issues early in feature blocks or pre-PR checks.

Runtime verification is the process of confirming code actually runs in a real environment by launching dev servers and executing smoke tests, e2e tests, and browser checks. You need it in CI pipelines, feature blocks, and pre-PR checks to catch runtime issues early.

Yes, runtime verification works with health and readiness endpoints by validating them during server startup. It monitors the dev server, applies configurable startup timeouts, and confirms the server becomes healthy and reachable before executing any test suites or browser checks.

End-to-end tests fail when the dev server is not fully started because the application is not yet reachable. Runtime verification solves this by applying configurable startup timeouts and validating health endpoints to ensure the server is ready before executing tests.

The best way to catch runtime issues before creating a pull request is to run automated pre-PR checks that launch dev servers, validate readiness endpoints, and execute smoke tests alongside Playwright or Cypress suites to confirm runtime viability in a real environment.
