Getting an error TypeError: describe is not a function

Question

I started creating a base test case using Mocha and Selenium Webriver. I get the following error when I try and run

> mocha test

TypeError: describe is not a function

My code sample:

var webdriver = require('selenium-webdriver'),
{describe, before, after, it} = require('selenium-webdriver/testing');
By = webdriver.by,
until = webdriver.until;

describe('scenarios', function(){
  beforeEach(function(){
    var driver = new webdriver.Builder().forBrowser('chrome').build();
    driver.get('http://google.com');
  });

  afterEach(function(){
    driver.quit();
  });

  it('find google', function(){

  });

});

I am not sure how to take care of this error since I tried all 1) globally and locally installing selenium-webdriver

Answer 1

   var Page = require ('../lib/home_page.js');
   var webdriver = require('selenium-webdriver');
  { describe , before , after , it }  require('selenium-webdriver/testing');

    var page;
   describe('library app scenarious', function() {
      beforeEach(function(){
          page = new Page();
          page.CheckOut();
      });

      afterEach(function(){
          page.quit();
      });

      it('Test1',function(){
        console.log('1testpass');
      });

      it('Test2',function(){
        console.log('2testpass');
      })
    });

Answer 2

I suppose it is not an issue with Selenium webdriver, it is a part of mocha that might be causing error. please look at it and that should solve

Answer 3

You need to install mocha globally.

$ npm install --global mocha
