isPresent

Validates if any element matching the target selector is rendered in the DOM.

isPresent vs. isVisible:

  • Both validate that an element matching the target selector can be found in the DOM
  • isVisible additionally validates that all matching elements are visible

Some uses cases for isPresent over isVisible:

  • To check for the presence of a tag that is never visible in the DOM (e.g. <meta>).
  • To validate that, even though an element may not currently be visible, it is still in the DOM.
  • To validate that an element has not merely been hidden but has in fact been removed from the DOM.

  • options Object Additional options
    • options.scope string Nests provided scope within parent’s scope
    • options.at number Reduce the set of matched elements to the one at the specified index
    • options.resetScope boolean Override parent’s scope
    • options.multiple boolean Check if all elements matched by selector are visible
    • options.testContainer string Context where to search elements in the DOM
