Configures Storybook's production builds for performance testing purposes by disabling certain features from the build. When running build-storybook, this feature is enabled by setting the --test flag.

The options documented on this page are automatically enabled when the --test flag is provided to the storybook build command. We encourage you to override these options only if you need to disable a specific feature for your project or if you are debugging a build issue.
