How to resolve "TypeError: Cannot read property 'equal' of undefined" in Mocha
When I run the following two files of code with mocha test/test.js:
// index.js const count = (string) => { if (string === "") { return {}; } else { return 1; } }; module.exports = count; // test/test.js const { expect } = require("chai"); const count = require("../index"); describe("count characters in string", () => { it("should return empty object literal when string is empty", () => { expect(count("")).to.eql({}); }); it("returns an object with a count of 1 for a single character", () => { expect(count("a").to.equal(1)); }); }); Test 1 passes, but for test 2 I get the following error:
1) count characters in string returns an object with a count of 1 for a single character: TypeError: Cannot read property 'equal' of undefined at Context.<anonymous> (test/test.js:10:25) at processImmediate (internal/timers.js:456:21) Please could you advise on what I should do to resolve this error and get my second test to pass?
Thank you.
expect(count("a").to.equal(1)); should be expect(count("a")).to.equal(1);. Wrong parenthesis placement.
