Can I have cy.task retry until assertion passes?

cy.task is great but does not retry its action, even if it is idempotent code. In situations like “checking if the database has been updated” (see https://github.com/cypress-io/cypress-example-recipes/commit/e6f3b4c2cc7731c1ec9936426bb71b5ecb9af9ae#diff-11f8d1f12b6eb04ff4abd710d5e9d786) it would be perfect NOT to implement “retry until my assertion passes” logic in Node, but instead have cy.task behave like a regular Cypress command.

Something like this

cy.taks('find item in the database').should('deep.equal', {id: 1, text: 'something'})

better formatting

cy.task('reset:db').then(...)
// "reset:db" runs once
cy.task('db:select', title, {timeout: 5000, idempotent: true}).should('deep.equal', ...)
// "db:select" is retried until the assertion passes or 5 seconds timeout reached

Closing as resolved since there is a workaround outlined.

If you’re experiencing a bug similar to this in Cypress, please open a new issue with a fully reproducible example that we can run. There may be a specific edge case with the issue that we need more detail to fix.
