Javascript Protractor - Seeing Outside Functions As Undefined

In specs/Test.js is a test definition: 'regex2' In pages/TablePage.js is a page object in regex2 there is a try to use a function from TablePage.js it('regex2', function(){

Solution 1:

The error comes from TablePage.js, it should be.

var TablePage = (function () {

  function TablePage() {
    this.workingBalanceField = element(By.xpath('//*[@id="root"]/main/section/div/div/div[5]/div/div[1]'));
  }

  TablePage.prototype.matchPriceRegex = function (locator) {
    this.text = locator.getText();
    expect(this.text).toMatch("\d{0,3}?,?\d{0,3}?\.?\d{0,3}?");
  };

  return TablePage; // return the class as outer function return value
})(); 
// `(function(...){})` return a function, you should use `()` to execute the
// return function to get the returned class: TablePage.

module.exports = TablePage;
