Reproducing and isolating issues and debugging tools and libraries

In this section, you will learn how to reproduce and isolate issues and how to use debugging tools and libraries.

Reproduce and isolate issues

Reproducing and isolating issues are important steps in software testing and debugging. They help you identify the root cause and the scope of a problem and provide clear and actionable feedback to developers.

Let’s learn how to reproduce and isolate issues:

• Unit tests: Write comprehensive unit tests that cover various scenarios and edge cases. Unit tests help reproduce issues in controlled environments, making it easier to identify problems within specific functions or modules.

  Here’s an example of performing a simple unit test using the assert module in Node.js:

  const assert = require('assert');

  function add(a, b) { return a + b; }

  // Unit test for the add function

  function testAdd() {

  const result = add(2, 3);

  assert.strictEqual(result, 5...
