Why We Test Software?

Imagine using a mobile app that crashes every time you click a button or a website that gives you the wrong information. This would be frustrating, right? That’s where software testing comes into play. It ensures that the software you use works smoothly, efficiently, and correctly. For beginners, understanding why testing is necessary is a crucial step in learning about software development.

What is Software Testing?

Software testing is the process of checking a software application to find and fix errors before it is released to users. It helps make sure the software does what it’s supposed to do without breaking or behaving unexpectedly. Testing can be done manually or using automated tools.

Why Do We Test Software?

Some of the reasons are as follows:

• To ensure the software meets user requirements
• To find and fix bugs before the software is released
• To check if the software performs well under different conditions
• To avoid costly failures after release
• To maintain user trust and satisfaction
• To ensure compatibility with various devices and systems
• To validate security, performance, and reliability
• Developers are not good testers
• Independent third party verification

 

Developers Are Not Good Testers

Developers focus on building the software and may overlook issues that others might catch. They tend to assume the software works as intended and may miss unexpected behaviors or edge cases.

Third Party Verification

Independent testers provide an unbiased view of the software. Their fresh perspective helps identify issues that the development team might have missed, ensuring better quality and reliability.
