then
▸ then(subject
): Assertable
<unknown
>
Wraps Cypress.Chainable and returns Assertable, decoupling test code form cypress 'should' assertions. This way you can add assertions of your own, by extending Assertable class.
Parameters
Name | Type |
---|---|
subject |
any |
Returns
Assertable

}

public when = {
