[sanchit121]

• @testing-library/react version: 11.2.2
• Testing Framework and version: Jest 26.6.3
• DOM Environment: jsdom

Relevant code or config:

export type RenderResult<Q extends Queries = typeof queries> = {
  container: Element
  baseElement: Element
  debug: (
    baseElement?:
      | Element
      | DocumentFragment
      | Array<Element | DocumentFragment>,
    maxLength?: number,
    options?: prettyFormat.OptionsReceived,
  ) => void
  rerender: (ui: React.ReactElement) => void
  unmount: () => boolean
  asFragment: () => DocumentFragment
} & {[P in keyof Q]: BoundFunction<Q[P]>}
