Cypress runs commands twice when no baseUrl defined

Current behavior:

Right now, whenever you start Cypress it will kick off some of the commands twice.

This isn’t a problem most of the time as tests should be self contained anyway, but if you are using before hooks (for instance, to login and store cookies, as suggested by the docs) it becomes quite detrimental.

Desired behavior:

Cypress should only run once.

Steps to reproduce:

//__bug.spec.js
describe('Bug?', ()=>{
    before(() =>{
        cy.task('message', 'I\'m running!');
    });

    it('Should only log once', () => {
        cy.visit('https://www.google.com');
    });
});

//index.js
module.exports = (on) => {
    on('task', {
        message (args) {
            console.log(args);

            return null;
        }
    });
};

Note: this isn’t exclusive to hooks! The below spec will also print unwanted results:

describe('Bug', ()=>{

    it('Should only log once', () => {
        cy.task('message', 'I\'m running!');
        cy.visit('https://www.google.com');
    });
    it('Should only log once', () => {
        cy.task('message', 'I\'m running!');
        cy.visit('https://www.google.com');
    });
    it('Should only log once', () => {
        cy.task('message', 'I\'m running!');
        cy.visit('https://www.google.com');
    });
    it('Should only log once', () => {
        cy.task('message', 'I\'m running!');
        cy.visit('https://www.google.com');
    });

});

Results:

Running: __bug.spec.js...                                                                (1 of 1)

If the commands are inverted (i.e., if you visit() before logging) then the results are fine, so maybe Cypress waits for visit then reboots?

@jennifer-shehane I see that you have labeled this as the intended workaround. However, have you seen occasions where this workaround does not work? It seems like I am not the only one who is unable to get this duplicate behavior to stop even when setting a baseUrl in the cypress.json file

[dawidkostyszak]

@jennifer-shehane same behaviour is when baseUrl is defined but I want to visit other page. Ie. I set baseUrl='https://www.google.com/' and in my test will do cy.visit('https://duckduckgo.com/') then all before commands will run twice.
