Exact Difference between System Testing and Acceptance Testing

Distinction between System Testing and Acceptance Testing

               System Testing
           Acceptance Testing
1. System Testing does not include any thing means it is not known by any other name.
1. Acceptance Testing Include Alpha Testing means it is also sometimes known as alpha testing.
2. User is not involved in System Testing.
2. User is completely involved in Acceptance Testing.
3. It is performed before Acceptance Testing.
3. It is performed after System Testing.
4. It is not the final stage of Validation.
4. It is the final stage of Validation.
5. System testing of software or hardware is testing conducted on a whole, integrated system to estimate the systems compliance with its specified set of requirements?
5. Acceptance Testing of software or hardware is testing conducted to evaluate the system compliance with its specified set of user requirements.
6. The only things Tester should be testing at the System Test stage are things that he and she couldn’t test before.
6. The only things Developer and User should be testing at the Acceptance Test stage are things that developer and tester couldn’t test before.
7. It is done to check how the system as a whole is functioning. Here the functionality and performance of the system is validated.
7. It is done by the developer before releasing the product to check whether it meets the requirements of user or not and it is also done by the user to check whether I have to accept the product or not.
8. It is used to check whether the system meets the defined Specifications or not.
8. It is used to check whether it meets the defined User Requirements or not.
9. System Testing refers to the testing of complete system as a whole that is carried out by testers and sometimes by developers to check whether it meets the system specifications or not.
9. Acceptance Testing is carried out by the users to determine whether they accept the delivery of the system or not. It is normally performed by users and sometimes developers are also involved in it.
10. System Testing determine the developer and tester for satisfaction with system specifications.
10. Acceptance Testing determine the customer for satisfaction with software product.
11. System Testing involves both Functional and Non- Functional Testing.
11. Acceptance Testing only involves the Functional Testing based on the requirement given by client/user.

Note

System Testing: The process of testing an integrated system to verify that it meets specified requirements is known as system testing. [Hetzel]

Acceptance Testing: After the system testing is over, the software/application is tested by the client/user to check whether it meets the requirements given by him or not. This is known as acceptance testing.


Acceptance testing can be performed either at the developer’s site (premises) or client site.

Difference Between Verification And Validation With Example?

Verification and Validation example is also given just below to this table.                Verification               Validation 1. Verification is a static practice of verifying documents, design, code and program. 1. Validation is a dynamic mechanism of validating and testing the actual product. 2. It does not involve executing the code. 2. It always involves executing the code. 3. It is human based checking of documents and files. 3. It is computer based execution of program. 4.  Verification uses methods like inspections, reviews, walkthroughs, and Desk-checking etc. 4.  Validation uses methods like black box (functional)  testing, gray box testing, and white box (structural) testing etc. 5.  Verification  is to check whether the softwar...

Regression Testing with Example and Strategies

Regression Testing is done to ensure that fixed bug does not affect the remaining functionality of the modules and also the functionality of the same module. In short you can say regression testing  is always done to verify that modified code does not break the existing functionality of the application and works within the requirements of the system. Regression Testing Example  For Example there are three Modules in the Project named Admin Module, Personal Information, and Employment Module and suppose bug occurs in the Admin Module like on Admin Module existing User is not able to login with valid login credentials so this is the bug.  Now Testing team sends the above - mentioned Bug to the Development team to fix it and when development team fixes the Bug and hand over to Testing team than testing team checks that fixed bug does not affect the remaining functionality of the other modules (Admin, PI, Employment) and also the functionality of ...

What Is Functional Testing Explain It with Example?

Functional testing means testing the application against business requirements. Functional testing is executed using the functional specifications given by the client or by the design specifications according to use cases given by the design team. Role of functional testing is to validating the behavior of an application. Functional testing is more important because it always verifies that your system is fixed for release. The functional tests define your working system in a useful manner. In functional testing tester has to validate the application to see that all specified requirements of the client whatever we have said in SRS or BRS have been incorporated or not. Functional testing  is always concentrating on customer requirements and whereas the Non-Functional testing is always concentrating on customer expectations. Functional and Non Functional Test Cases Functional test cases target business goals and non functional test cases target performance, resource...
