function expectOutput()

Returns an assertion for the elements matching the provided filters.

function expectOutput(
  select: OutputSelectFilter & {
    timeout?: number;
  },
  ...nested: OutputSelectFilter[]
): OutputAssertion;

Notes

• This function returns the same result as expectOutputAsync but without waiting for (new) rendering to complete.
• This function uses TestRenderer.expectOutputAsync(), refer to its documentation for details.

Parameters

• select — A set of output filters to match, including optional timeout (defaults to 200ms)
• nested — Further output filters to match, if any

Return value

A promise that’s resolved to an OutputAssertion instance for matching output, or rejected when a timeout occurs.
