System Testing

The process of testing the complete and integrated software product to meet specified requirements is said to be System Testing. The main aim of this testing is to test the whole software product which is already integrated. It is the third level of software testing. Independent software testers will perform this testing.

Working Process of System Testing

• Initially, it will perform testing on fully integrated applications to verify that the interaction is made perfect with the application.
• To Optimize each and every input of the application or product to get the expected output
• Finally, make sure that the application got the desired output which will be ready for the final level of testing

Types of System Testing

It is broadly divided into two types namely Functional Testing and Non-Functional Testing

Again Functional Testing is divided into many types

• Acceptance Testing
• Beta Testing
• Integration Testing
• Interface Testing
• Regression Testing
• System Testing
• Sanity Testing
• Smoke Testing
• Unit Testing

Non-Functional Testing is also divided into many types

• Compatibility Testing
• Compliance Testing

• Performance Testing
• Recovery Testing
• Reliability Testing
• Security Testing
• Usability Testing

Among the above testing types, this testing mainly involves for following types

• Usability Testing
• Load Testing

Methods of System Testing

According to software testing, there are 3 methods of testing available namely

• Black Box Testing
• White Box Testing
• Grey Box Testing

Among these three methods, this testing will come under the Black Box Testing Technique

Advantages

• It performs testing on end-to-end scenarios of the system
• This testing helps to determine the errors or bugs before the product goes live
• It helps in testing both application and business requirements

Disadvantages

• As it needs to test the whole system it requires a lot of time
• Depending on the business requirements and application architecture cost may also increase
