Testing Gatsby Sites Built with AI

AI-generated Gatsby sites frequently contain GraphQL queries that work in development but fail in production. Queries may reference fields that do not exist in the schema, use incorrect filter syntax, or fail to handle null values in source data.

Gatsby's image processing pipeline is another common failure point. AI tools generate image queries with incorrect transformations, broken lazy loading, or missing alt attributes. The result is pages with broken images, placeholder images that never resolve, or images that load at the wrong dimensions.

Testers on DidItWork.app visit every page of your Gatsby site, verifying that content displays correctly, images load properly, and data-driven pages contain all expected information. They catch the gaps that automated build checks miss.

Gatsby's plugin ecosystem is extensive, and AI tools frequently configure plugins with incorrect options, incompatible versions, or conflicting settings. Source plugins may fail to fetch data, transformer plugins may produce incorrect output, and SEO plugins may generate malformed meta tags.

AI-generated gatsby-config files sometimes include plugins that are deprecated or no longer maintained, leading to build warnings that hide genuine errors. Plugin ordering matters in Gatsby, and AI tools rarely get this right, causing data transformation pipelines to break.

Testers verify the end result: that all pages render, that meta tags are correct, that images are optimized, and that third-party integrations like CMS content and analytics work properly.

Testers evaluate your production Gatsby build comprehensively. They test page navigation, link prefetching behavior, dynamic client-only routes, and any server-side rendered or deferred static generation pages. They verify that the site works correctly with and without JavaScript.

Client-only routes in Gatsby are a frequent source of bugs. AI tools generate client-only routes that flash a 404 page before rendering, lose state on refresh, or fail to handle direct URL access. Testers check all of these scenarios.
