如何使用cypress在网页上运行javascript

Question

I'm writing a cypress test and following javascript works in the chrome console

$.event.trigger({
type: "Scan",
message: "scanned",
time: new Date()
});

Is there a way I can run the command above in cypress when I get to the specific page?

Answer 1

I believe you can do this within a .then() block. Since cy commands run asynchronously and get queued up with all the other cy commands, .then() will delay the execution of the JavaScript within until the cy command actually does its thing.

So like this...

cy.visit('/my-special-page').then(() => {
   // Do your JavaScript here
})

Answer 2

Try this:

Cypress.$.event.trigger({ type: "Scan", message: "scanned", time: new Date() });
