A quick way to make unittests for your code

let rich = require("noderich.js");

class TestResults {
    constructor(examples) {
        this.total = 0;
        this.passed = 0;
        this.examples = examples;
        this.answers = [];
        this.computed = false;
        this.percent = 0.0;
    }

    add_results(expected, result) {
        if (expected === result) {
            this.passed++;
        }
        this.total++;
        this.answers.push(result);
    }

    compute() {
        this.percent = Math.round(this.passed / this.total * 100 * 100) / 100;
        this.computed = true;
    }

    print_results(show_succeded = false) {
        if (!this.computed) {
            this.compute();
        }
        if (this.percent === 100) {
            console.log(`${rich.Style.BRIGHT}${rich.Fore.GREEN}All tests passed! (100%)${rich.Style.RESET_ALL}`);
            return;
        }
        for (let i = 0; i < this.examples.length; i++) {
            let expected = this.examples[i][1];
            let result = this.answers[i];
            if (result !== expected || show_succeded) {
                console.log(`Test ${i + 1} [${result === expected ? 'SUCCEEDED' : 'FAILED'}]: ${this.examples[i][0]} -> ${expected} (got ${result})`);
            }
        }
        console.log(`\n${rich.Style.BRIGHT}${rich.Fore.GREEN}Failed ${this.total - this.passed} tests (${this.percent}%)${rich.Style.RESET_ALL}`)
    }
}
