Many assertions compare two objects or properties of these objects. Passing twice the same argument is likely to be a bug due to developer’s
carelessness.
This rule raises an issue when a Chai assertion is given twice the same argument.
Noncompliant Code Example
const assert = require('chai').assert;
describe("test the same object", function() {
it("uses chai 'assert'", function() {
const expected = '1'
const actual = (1).toString()
assert.equal(actual, actual); // Noncompliant
});
});
Compliant Solution
const assert = require('chai').assert;
describe("test the same object", function() {
it("uses chai 'assert'", function() {
const expected = '1'
const actual = (1).toString()
assert.equal(actual, expected);
});
});
