Ninja Forms renders forms entirely in JavaScript, making them uniquely tricky to test. FormsCheck waits for client-side rendering, auto-detects all fields, and tests the form like a real user.
Ninja Forms' client-side rendering architecture creates unique failure modes:
Unlike other form plugins, Ninja Forms renders the entire form in JavaScript. Any JS error — from a conflicting plugin or theme — can prevent the form from appearing at all.
Ninja Forms relies on Backbone.js and Underscore.js. Plugins that modify or dequeue these libraries can silently break form rendering.
Ninja Forms uses an action pipeline for email notifications, redirects, and integrations. A broken action can stop emails while the form shows success.
Aggressive page caching can serve stale Ninja Forms nonces, causing all submissions to fail with a generic error that's hard to debug.
FormsCheck knows that Ninja Forms renders client-side. It waits for the .nf-form-layout to fully render before detecting fields — handling the async nature that trips up other testing tools.
Fills every field and clicks the submit input. Waits for .nf-response-msg to confirm successful submission.
Verifies email delivery to a real inbox. Instant email or Slack alerts when anything fails.
