How to set a global array and fill it with data?

[thepixelhead]

If I run the following test probably the arrays and / or global variable / array do not work.

In the browser test step log it says "wrap null". So I assume the values and arrays are empty.

i have not found a solution so far. Any idea? What am I doing wrong?

// Global variable for later use
let globalValues;

describe('Cypress Test Global Array', () => {
    it('Read a table row and store the data in an array for further calculations later in the test', () => {

        let valuesArray = [];

    // Run through the table row and save values in an array

        cy.get('.table1 > tbody > tr.table_class3 > td:nth-child(1)').each(($e1, index, $list) => {
            var titletext = $e1.text()
            if (titletext.includes('Amount Summery')) {
                let values = [];
                // Run through the columns 2 to 15
                for (let i = 2; i <= 15; i++) {
                    cy.get(`.table1 > tbody > tr.table_class3 > td:nth-child(${i})`).eq(index).then(function (amount) {
                        values.push(amount.text().trim());
                    });
                }

                valuesArray.push(values);
            }
        });

    // Wait until all values are read and save them into the global variable

        cy.wrap(null).should(() => {
            globalValues = valuesArray;
        });

    // The global variable is ready to use for other tasks in the test

    })
})

Synchron / asynchron issue:

This does not work neither for the wrap part:

cy.get('#anHTMLelement').then(function(wrapfunction){
    cy.wrap(null).should(() => {
            globalValues = valuesArray;
        });
})
