Set timeout for Cypress expect assertion

Question

My issue is that I'd like to have a timeout on the expect assertion from Cypress's library but can't seem to figure out a method to do so.

I've tried greatly increasing the global timeout in cypress.conf; however, that didn't work.

if ($widget.find('report-widget')) {
  SVGCount++;
  expect(barGraphsChange[index]).to.not.equal(undefined)
  console.log(barGraphsChange, index)
  cy.getBarGraphTotal(SVGCount, barGraphsChange[index])
}

If not a timeout then a reasonable workaround would be nice as well, Thanks!

Also a note: barGraphsChange[index] is in the process of getting calculated and assigned from a called custom Cypress command earlier on during this phase.

You can customise your expectations with should(), and this will automatically retry your assertions for either the specified timeout, or the global defaultCommandTimeout if none provided. In your case I could probably imagine wrapping your object, specify a timeout and then passing your logic to should:

cy.wrap(someFunction, {timeout: 25000}).should(someFunction => expect(someFunction()).to.eq(someValue))
