ESLint - Getting error - 'expect' is assigned a value but never used

Question

const supertest = require('supertest-as-promised');  
const expect = require('chai').expect;  

const request = supertest(process.env.BASE_URI);`

I am getting this ESLint error:

'expect' is assigned a value but never used'

for expect statement. What changes could I make to get rid of these errors from my all .js files?

Answer 1

You are encountering the no-unused-vars rule from ESLint. You can read more about that from their documentation.

The reason ESLint is warning about you about this is that you've declared expect and assigned a value to it.

const expect = require('chai').expect; 

However you haven't used it anywhere.

To get rid of the error you need to use expect somewhere.

describe('A test', () => {
  it('should do something', () => {
    expect(something).to.be.true;
  });
});
