Debug With Assert

noreply@example.com (AG Sayyed) — Thu, 13 Nov 2025 13:46:44 +0000

This document explores debugging Python programs using assert statements as sanity checks to catch bugs early in development. Assertions validate assumptions, check preconditions, verify intermediate states, and provide clear error messages when conditions fail, enabling proactive bug detection throughout the coding process.

Introduction

A developer’s worst nightmare is spending hours developing code only to discover multiple bugs right before deployment. Instead of waiting until the last minute to check code correctness, developers should test and validate throughout the development process. Assert statements provide a mechanism for these continuous sanity checks.

Working with Someone Else's Code

This document provides strategies for understanding and fixing problems in code written by others, covering techniques for reading unfamiliar code, leveraging comments and tests, navigating large codebases, and building skills through practice with open-source projects.

Introduction

In IT roles, fixing problems in code written by others is a common task. Whether working with open-source software or internal company projects, understanding unfamiliar code requires specific strategies and approaches. Developing these skills enables effective troubleshooting and maintenance of codebases regardless of original authorship.

Component Testing

This document covers the fundamentals of testing React components, including the advantages and disadvantages, testing approaches, Arrange-Act-Assert pattern, and popular tools like Jest and React Testing Library.

Introduction to Component Testing

Testing is the process of reviewing how code executes, either line-by-line or through suites that verify application behavior. It ensures that applications work as intended and helps prevent regressions.

Advantages and Disadvantages of Testing

Advantages:

Prevents unexpected regressions
Allows developers to focus on current tasks
Enables modular construction of complex applications
Reduces the need for manual verification

Disadvantages:

This document details the seven phases of the application development lifecycle, including requirements gathering, analysis, design, coding, testing, production, and maintenance. It also explains the importance of organizing code into multiple files for efficient development and maintenance.

Application Development Lifecycle

The application development lifecycle is a structured process that guides the creation of software from initial concept to ongoing maintenance. Each phase ensures the application meets user, business, and technical needs while remaining reliable and maintainable.

Why don't Developers want to test?

noreply@example.com (AG Sayyed) — Mon, 21 Jul 2025 00:00:00 +0000

This module examines why developers often avoid writing tests, the consequences of skipping testing, and how a strong test suite supports future development, code safety, and collaboration in open source and enterprise environments.

Introduction

Testing is frequently neglected by developers for reasons such as overconfidence in their code, lack of time, or the belief that testing is unnecessary. However, skipping tests can lead to undetected bugs, compatibility issues, and future maintenance challenges.

SCSS Styling System - Quick Reference Guide

🚀 Quick Start Testing (5 minutes)

1. Verify Tests Pass

1npm run test:anki

✅ Expected: 52 tests passing

2. Verify CSS Files Exist

1npm run anki:styles:list

✅ Expected: psychology.css (16 KB), devops.css (17 KB)

3. Generate Test APKG from Real Data

 1conda activate ags-anki
 2
 3python3 << 'PYTHON'
 4import json
 5from pathlib import Path
 6from scripts.anki.apkg_generator import APKGGenerator
 7import tempfile, shutil
 8
 9# Load real psychology data
10with open("data/course/psychology-l2/01/01m/001/anki/01-counselling-skills.json") as f:
11 data = json.load(f)
12
13# Ensure course metadata exists
14if 'course' not in data['metadata']:
15 data['metadata']['course'] = 'psychology'
16
17# Generate APKG with styling
18with tempfile.TemporaryDirectory() as tmpdir:
19 gen = APKGGenerator(verbose=True)
20 apkg = gen.generate_from_data(data, tmpdir, data['metadata'].get('deck_name'))
21 
22 # Copy to Desktop
23 shutil.copy(apkg, Path.home() / "Desktop" / "psychology-real-data.apkg")
24 print(f\n✅ APKG copied to ~/Desktop/psychology-real-data.apkg")
25
26 print(f" Size: {apkg.stat().st_size / 1024:.1f} KB (includes psychology CSS)")
