What is the difference between testing and quality assurance (QA)?

This question is surprisingly popular. However, the answer is quite simple. The goals of both are different: The goal of testing is to find the errors. The goal of QA is to prevent the errors in the program.

Testing means QC. i.e. It measures the quality of the product. 
QA measures the quality of processes involved in creating a quality product.

If testing and Quality assurance are different, then why we call a tester as Quality assurance tester.

testing is done by tester to find the errors in the project hre we check the build product is correct or not. it is validation

quality assurance is done by the developer while they are in the developing  the project (bug free product) here we check whether we are building the right product. it is verification

QA is more a preventive thing, ensuring quality in the company and therefore the product rather than just testing the product for software bugs

* TESTING means "quality control"
* QUALITY CONTROL measures the quality of a product
* QUALITY ASSURANCE measures the quality of processes used to create a quality product.

Quality assurance is creating or streamlining existing testing techniques/protocols/procedures to create a quality product. Quality assurance will make sure correct and apt quality guidelines and procedures are set for the QC department to test a product.

Testing is the act of performing some checks or tests to make sure the product under test adheres to the quality standards and requirements (shape, size, colors etc).

The product can be anything a toothpaste, gold bangle, or even a software application.
