I need to access data outside from then.

   function getText() {
    cy.get('#locator')
        .then(function($elem) {
            let aaa = cy.log($elem.text());
            return aaa.toString();
        });
   }

   var returnedValue = getText();
   cy.log(returnedValue);

I get the error: Argument of type 'void' is not assignable to parameter of type 'string', when I try to print the output in the Cypress test runner log.

CodePudding user response：

1. Your getText() does not return anything, hence the argument of type void... error.
2. You're trying to convert a cy.log() command into a string, which is not feasible.

Instead, let's yield the result of your getText() command into a .then() that uses cy.log();

const getText = () => {
  return cy // return the entire chain
    .get('#locator')
    .then(($elem) => {
       return $elem.text(); // return the text of the element
    });
}

getText().then((result) => {
  cy.log(result);
});

If you need to do something besides cy.log() that value, just do the same, and use that result variable.

getText().then((result) => {
  // code that uses result
});

I would not advise declaring a variable and setting it equal to getText(), because that is going to assign the variable a value of type Chainable<string>, and not string, which is not what you want or need.
