Difference between System Testing and Acceptance Testing

The foremost purpose of leading a test on a Software or application is to verify whether it is carrying out its functions, which it was designed to do and to ensure that it is free from any sort of unwanted errors, defects and bugs. Software Performance Testing is an extensive selection of essential testing services based on several factors such as the stage of testing (early or final), type of product, its characteristics and usage, load, target audience etc.

There are a number of testing phases and Tests involved such as White Box Testing, Black Box Testing, Regression testing, Performance testing, Mobile testing, User Experience Testing, Unit testing, Integration Testing, System testing, Acceptance Testing or Manual testing and Automated Testing.

This Blog will mainly focus on the basic Difference between the System testing and the User Acceptance testing (UAT).

System Testing

System Testing is a level of Software Testing where the finished product or a fully integrated application/ Software is tested to check and evaluate its compatibility with the requirements. So, it can be defined as a procedure of Testing a cohesive system to validate its functional requirements.

It is the third level of Software Testing that is done on a completely developed product after successfully running the Unit Tests, and the Integration Tests.

  • It is done to confirm and check the functionality of the developed product.
  • It can be either done by the Software developers or the Quality Assurance testers both.
  • System testing is done after performing Unit testing and Integration testing.
  • It contains larger number of negative test cases.
  • It covers the behavioral and functional aspect of the software or application.
  • The defects and errors found at System Testing stage are rectified and fixed as soon as possible.
  • It can be done either manually or automated by preparing Test cases in advance.

 

User Acceptance Testing (UAT)

It is done by the end user or client to check whether the final product is completely fit and accepted with respect to the requirements and their needs. It is essential to determine if the end result of the developed software or application passes the acceptance criteria of the end user or customer.

It is the final level of Software Testing that is done after successfully running the Unit Tests, Integration Tests and the System Tests.

  • It is done to assess whether the developed product meet all the client requirements.
  • Acceptance tests are conducted by the testers or end users and customers.
  • It contains larger number of positive test cases.
  • It covers only the acceptance criteria and requirements provided by the clients.
  • The defects and errors noticed at the Acceptance testing stage are considered to be a failure of the product.
  • It is done randomly by using Black Box testing method without using any defined set of Test cases.
