Fundamentals of Software Testing and Quality Assurance

Posted on Apr 1, 2026 in Software Engineering

What is Software Testing?

Software Testing is the process of checking a software application to find errors (bugs) and ensure that it works correctly according to the requirements.

Simple Definition

Software testing means verifying and validating that a program does what it is supposed to do and is free from defects.

Key Points

  • Helps find mistakes or bugs
  • Ensures quality and reliability
  • Checks if software meets user requirements
  • Improves performance and security

Example

If you create a login page, software testing will check:

  • Whether the username and password work correctly
  • Whether wrong inputs show proper error messages
  • Whether the system is secure

Types of Software Testing

  1. Manual Testing – Done by humans without tools
  2. Automation Testing – Done using software tools
