Is Software Quality Assurance same as Software Testing?
August 17, 2017
Software development is a complex process where we need to ensure that the end product matches the client's needs. In addition, it also needs to provide an enhanced customer experience. That's where software quality assurance and software testing comes into the picture.
On surface, the two appear similar; however, there is a thin line of demarcation between Software Quality Assurance (QA) and Testing.
They have different goals, features and methods to apply. Software Quality Assurance is based on a logical plan to deliver a bug free application including Software Requirements Specification (SRS) document. Software QA also creates and implements methods and procedures to improve the overall development cycle, whereas Software Testing concentrates on verifying and validating the product to discover bugs and locate defects.

Software Quality Assurance is an approach which is designed to ensure that the application meets the specific requirement. It is a planning strategy for testing process of an application aimed at quality product yield. QA is all about preparing a proper plan or strategy followed by testers to execute various test cases and make the application bug free.
On the other hand, software testing is an activity to check whether the actual result matches with the expected result or not. It also executes various test cases to check the software. It identifies gaps, errors and missing requirements and try to fix them all. It can either be done by manual or automated testing.
There can be an overlap between quality assurance and testing in projects, especially small scale ones. Testing might provide important quality related information about the product, but quality assurance is what uses this information to improve the quality related processes. In some projects, an external Quality Assurance might be engaged to conduct an audit of the quality related processes.
Software Quality Assurance is not equal to Software testing. Why?
- Software QA is all about management staff, it prepares a proper documented plan which is to executed by tester for testing an application or software.
- Its focus is on Quality Control and meeting the requirements. Software QA is process oriented as it prevents errors from occurring.
- The main aim of Software QA is to assure the quality of the software which is to be delivered.
- Software Testing, the other hand, is simply the process of finding bugs or defects in a software using test cases.
- It’s a product-oriented approach unlike the process-oriented QA that focuses on making the software bug free.
- It ultimately focuses on the overall quality of the Software just like Software QA.
QA makes it easy for a tester to find bugs as he has to follow a particular pattern. The main aim of Quality Assurance and Testing is to deliver an error free product which meets functional and nonfunctional requirements with improvised quality.
Software development or product engineering is incomplete without QA and Testing. It is crucial to ensure that the end product is that of superior quality.
