Unit Testing

   A Must-Know for Every Programmer Unit testing is one of the most crucial topics that every programmer should be familiar with. It ensures the correctness of individual components of a program by testing them in isolation. In this blog, we will focus on unit testing in Python and explore five popular libraries that can be used for this purpose: Pytest PyUnit Robot Framework Splinter Behave Why Do We Need Unit Testing? The primary purpose of unit testing is to validate that each part of your application works as expected. Let’s break it down with an example: As a developer, you might build an application or write a piece of code for a specific task. Unit testing ensures that your application functions correctly from every perspective. By storing test cases in a separate test file and importing your code’s functions, you can efficiently run tests using a library like Pytest to verify the correctness of your code. The terminal output will indicate whether the tests pass or...

RISC vs. CISC: Which Powers Your Devices?

  RISC vs. CISC: Understanding the Core of Computer Architecture In today's world, almost everyone uses a computer in some form—whether it’s a smartphone, laptop, or desktop. Yet, as students or professionals, very few people stop to think about how instructions are processed inside these devices . As a layman, it might seem like magic, but as a Computer Science student , it’s essential to understand what happens behind the scenes. Have you ever wondered how the lines of code in your program are translated into actions? What instruction set is used to process these tasks?    CISC and RISC First, let’s understand what a processor is. A processor is the brain of the computer. It receives instructions and data, telling it what to do and what not to do. Essentially, it manipulates data to perform tasks. Every processor has an instruction set , which is a collection of instructions or operations that the processor can perform. Computer architecture is classified into...

The Building Blocks of Modern Computing

What is a Thread? Before diving into the concept of threads, let’s consider a common example. Imagine a company named X with four employees. Each employee is assigned their own task, and they upload their completed work to a shared database. These tasks might range from creating an entire application to completing a small part of it. At the end of the day, all their contributions combine to form the final application. In this analogy, each employee represents a thread , while the company represents the process .   Key Terms in Threading Single-threaded Process : In a single-threaded process, one thread executes the entire sequence of operations sequentially. Multi-threaded Process : In a multi-threaded process, multiple threads work together, with each thread handling a specific part of the sequence of operations. The combined effort of these threads results in the completion of the task. Shared Resources in Threads All threads within the same process share certain resources, such...
