Expose ReactN and use it from Cypress.

I was able to do it.

https://gyazo.com/4555d5f590786e4b4d2a4982ddf31aec

code:App.tsx

function App() {

return (...);

}

code:index.tsx

setGlobal(INITIAL_GLOBAL_STATE);

const movidea = {

getGlobal,

setGlobal,

};

const debug = {};

declare global {

interface Window {

debug: any;

movidea: typeof movidea;

}

}

window.movidea = movidea;

window.debug = debug;

I have setGlobal, etc. in movidea (app name) to make it easier for users (mainly me) to hack when the app is released, but I think it is also possible to design it in the debug and remove it in the release build.

test code

code:cypress/.../adjust_font_size.js

/// <reference types="cypress" />

describe('adjust font size', () => {

beforeEach(() => {

cy.visit('/')

let a = 1;

let b = 1;

const fusens = [];

for (let i = 0; i < 11; i++) {

fusens.push({

text: ">" + "a".repeat(a),.

x: 50 * i,

y: 50 * i,

});

}

cy.window().its('movidea').then(movidea => {

setTimeout(() => {

movidea.setGlobal({ fusens });

})

});

})

it('fusen sizes', () => {

cy.get('.fusen').should('have.length', 12).first()

.should("have.css", "font-size", "66px")

.should("not.have.css", "align-items", "flex-start")

cy.get('.fusen').eq(1).should("have.css", "font-size", "53px")

cy.get('.fusen').eq(2).should("have.css", "font-size", "38px")

cy.get('.fusen').eq(10)

.should("have.css", "font-size", "10px")

.should("have.css", "align-items", "flex-start")

})

})
