Erroneous assertion not breaking the Scenario

What are you trying to achieve?

I’m trying to do an assertion in a test Scenario with 2 values taken from two different pages on a website

What do you get instead?

Even forcing the assertion to fail, test keeps outputting that it PASSED.

A snippet of the assertion part:

        let assert = require('assert');
        I.say('Assertion...');
        assert.true(value1 == (value2 + value3));

I need like a I.assertThat(expression) in order for the test to fail when values don’t match. Right now I’m researching about assertions on codecept and trying to figure out a solution for that.

Details

• CodeceptJS version: 1.1.1
• NodeJS Version: 9.4.0
• Operating System: Linux Mint
• WebDriverIO

I looked at the package.json and found no dependency to ‘assert’, so they must be using the node assert library. https://nodejs.org/api/assert.html

As per the node js docs, there is no .true property, so unless you’re using another assert library (or I’m reading the docs wrong).

Though I’ve been using the chai (http://chaijs.com/api/bdd/) expect/should module in my project with success. Here’s an example.

const { expect } = require('chai');
expect(true).to.be.true;

I would suggest looking at the source code for the Helpers i.e. in ./lib/helper/WebDriverIO.js. They provide great examples on how to do it.

i.e. this is from the WebDriverIO.js Helper

  async seeInTitle(text) {
    const title = await this.browser.getTitle();
    return stringIncludes('web page title').assert(text, title);
  }
