The goals of both are different: The goal of QA is to prevent the errors in the program. The goal of testing is to find the errors.
The most brief difference is QA includes testing but vice a versa is not true.
____ JAY _____
QA is responsible 4 monitoring and improving entire S.D.L.C phases nothing but preventing the bug
testing is finding bug.

Testing examining the behaviour of the application by executing on sample data sets.
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: A planned and systematic pattern of actions necessary to provide adequate confidence that the product optimally fulfills customers' expectations.
Testing:between expected and actual behavior.

Definition of Software Quality as defined at NASA (National Aeronautics and Space Administration
at USA) is like:
The function of software quality that assures that the standards, processes, and procedures are appropriate for the project and are correctly implemented.

The difference in QA and Testing can also be stated as under:
Testing involves operation of a system or application under controlled conditions and evaluating the results. It is oriented to 'detection'.

Software QA involves the entire software development process - monitoring and improving the process, making sure that any agreed-upon standards and procedures are followed, and ensuring that problems are found and dealt with. It is oriented to 'prevention'.

Therefore, Remember major shift in QA is PREVENTION of a great killer- BUG rather than to DETECTION of a BUG.

Hello buddy,

Quality Assurance Testing

Quality Assurance analyst tests whether the modules are working properly. They test the software and make sure it meets certain quality standards. They test for bugs and they test that the software works as intended, including integration and data points. They write test cases to test how efficient the software is with different inputs in different conditions, etc.

Testers analyse what the software does and report it on the level of quality. QA testers exercise parts of the software, which according to them may be weak or which may not be interacting well.

QA and Testing both have to make software better, but QA enhances the quality by improving the development process and testing enhances it by finding the bugs in the existing code/software.

Quality Assurance and control are part of software testing :

Quality Assurance

1)Quality Assurance is process oriented

2)It is a staff function.

3)It is done before Quality Control.


Quality Control

1)Quality Control is product oriented

2)It is a line function.

3)It is done only after Quality Assurance activity is completed.

Hi Anna,

I would say that QA has a bigger scope and testing is only one part of it. Today, most of the software testing companies deal in QA rather than testing only. Following are few basic differences between QA and testing:

QA (Quality Assurance) refers to the activities designed to ensure that the software corresponds to the specs. On the other hand, Software Testing refers to exploring a system in order to find problems/defects/bugs.
QA is process oriented, whereas Testing is product oriented.
QA is a preventive activity whereas testing is a corrective activity.
QA's aim is to assure the quality, on the other hand, purpose of testing is to control the quality.

Thanks,
Anand
