VistasCypress test if input field value has multiple lines
I want to check with a cypress test if the value is correct in a single-line text fields and multi-line text area.
I here have a single line box where I use the code down below to add an input:
cy.followLabel("When did the incident happen?").type("single \nline");
Same thing for the multi line text area
cy.followLabel("Deenter code herescribe what happened").type("multiple \nlines");
I tried to validate it with .should() but haven't found any chainers that would suit my need.
Is there something like .contains("\n")?

Chai Assertion Library has a singleLine assertion in the chai-string module.
singleLine
assert.singleLine('abcdef');
expect('abcdef').to.be.singleLine();
To use assertions from other libraries, see Cypress recipe Adding Chai Assertions
Simple example
Install
yarn add -D chai-string
//or
npm install -D chai-string
Test
chai.use(require('chai-string'));
it('tests for singleLine', () => {
cy.get('input')
.type("single \nline")
.invoke('val')
.should('be.singleLine') // passes
cy.get('textarea')
.type("multiple \nlines")
.invoke('val')
.should('not.be.singleLine') // passes
})

You can directly check that the innerText has the new line character \n.
cy.get('selector').then(($ele) => {
expect($ele).to.contain('\n')
})
In case your inner text doesn't have the newline characters, you assert the style tag containing overflow-wrap: break-word
cy.get('selector').should('have.attr', 'style').and('include', 'overflow-wrap: break-word')

I know there is an assertion "match" for regex.
match(RegExp)
Aliases: matches
expect('testing').to.match(/^test/)
(from https://docs.cypress.io/guides/references/assertions)
So in your case the regex could be match(/.*\n.*/gm)
