How to use electron.getElectronNodeVersion method in Cypress

All the code and referenced modules in index.js are loaded before your test file. So you need to refer(require) commands.js in your index.js file. You can however import commands.js module directly in your test file but then you need to include it every test file. Recommended approach is to include it in index.js file and you are not worried about explicitly refer in your test files.

If you move the class .title into command .contains() it will focus solely on the element you wish to test, i.e two criteria will be tested in one command call and it will find the specific element.

cy.contains('.title', 'Hello').should('be.visible')

Tracking through the error in the console, it's clear that Cypress is not handling the export const getInternationals construct correctly, but cannot tell why at a glance.

NOTE: re-basing the import doesn't work, left for continuity of discussion

You can dodge the problem by spying like this in your test

const spyBase = {
  getInternationals: internationals.getInternationals
}
cy.spy(spyBase, "getInternationals");

expect(spyBase.getInternationals).to.be.called;

If you can alter the source code, add a default export to the module

export const getInternationals = ...

export default {
  getInternationals
}

and import it like so

import internationals from "../../../src/api/Internationals";

This answer provides most of the information needed (thanks CRayen for pointing me to another question (which was a duplicate of another)).

Basically you can put a .eslintrc file into any subfolder in which you want to override rules. Then you need to add a section like the one in the answer:

"overrides": [{
  "files": [ "*.spec.js" ],
  "rules": {
    "no-unused-expressions": 0
  }
}]

where you explicitly turn off the rules you don't want to be used to check the files listed by setting them to 0.

cy.task() needs to use .then() to get the value, like this example.

cy.task("connectDB", "select user_id from user_details where first_name='XYZ'")
  .then(user_id => {
    cy.request({
      method: 'DELETE',
      url: 'localhost:8080/user/' + user_id
    }).then((res) => {
      expect(res.status).to.eq(200)                // passes
    })
  })

If you try to assign the return to a variable let user_id = cy.task("connectDB"... you will get a chainer object, but it's not much use without a .then() to extract the value.

Cypress exec task needs to be executed from it context which is synchronous so I wouldn't say it's possible as it's not compatible with Cypress test building model.

Have you considered orchestrating everything from JMeter instead? For example you can use setUp Thread Group for spinning up the environment, one Thread Group for creating the load and another Thread Group for checking the frontend via Cypress Tests. By the way, there is JMeter integration with Selenium browser automation framework via WebDriver Sampler.

Issue resolved by reverting back cypress version to 7.6.0.

Solved by adding custom chainable interface to support folder

declare namespace Cypress {
  interface Chainable {
    createInbox(): Chainable<any>;
    waitForLatestEmail(inboxId: number): Chainable<any>;
  }
}

Now cy.server is deprecated, you can use cy.intercept instead:

cy.intercept('http://api.company.com/', (req) => {
  req.headers['authorization'] = `token ${token}`
})
