software teseting (wb/ios/android)

Verification vs. Validation: Verification involves checking if the software is being built the right way (e.g., meeting technical specifications), while validation confirms that the software actually meets the customer's needs and requirements (building the right product).

Manual Testing: Human testers interact with the application to find bugs without automation tools, which is especially useful for exploratory and usability testing.

Automated Testing: Testers use scripts and tools to automatically execute tests, which is beneficial for repetitive tasks and large systems, ensuring consistency and efficiency.

Shift-Left Testing: A modern practice where testing begins earlier in the development cycle, even at the design phase, to uncover issues sooner and reduce costs.
