Hardware Testing

Hardware Testing is the methodical process of inspecting a device's physical components to confirm their reliability, performance, and durability. Unlike software testing, which checks the code, hardware testing focuses on the tangible parts — from the circuit board to the user interface. Its goal is to find and resolve any physical defects or design flaws that could affect the user's experience.

Example: A company is developing a new biometric security scanner for corporate offices. Before the product is sold, the team performs extensive hardware testing. They would:

  1. Conduct a durability test by simulating thousands of user touches on the scanner's screen to ensure it doesn't wear out or break.
  2. Perform a performance test on the fingerprint sensor to measure how quickly it can scan a finger and grant access, ensuring a smooth user flow.
  3. Run a reliability test by leaving the device on and scanning thousands of fingerprints over several weeks to check for any failures.

This process ensures that the physical device is robust and dependable for daily use.
