What is Acceptance Testing? Types and Examples – W3Softech

Acceptance Testing

Acceptance Testing is the final level of software testing. The main aim of this testing is to determine the working process of the system by satisfying the required specifications and it is acceptable for delivery. It is also known as End-User Testing. It also works under the Black Box Testing Method.

Types of Acceptance Testing

The most important seven types of this testing are

User Acceptance Testing (UAT)

The name itself says that it is from the user point of view. It helps to determine whether the system is working for the user with the given specific requirements. Here, the user refers to whom the system is going to handle after completion of all the testing levels. Usually, customers or customer’s customers will perform this testing.

Business Acceptance Testing (BAT)

It helps to check whether the system satisfies the business requirements and specifications. The main aim of this testing is to help in increasing business profits by considering market strategies and technologies.

Contract Acceptance Testing (CAT)

The name itself says that it helps to test the product with all acceptance test cases within the contract period of time. The contract may be like payment will be done before the product goes live or after the product goes live.

Regulation Acceptance Testing (RAT)

If testing undergoes all the rules and regulations that are released by the government then it is said to be RAT. Not even a single violation has not to be found while performing this testing if any occurs then the whole product will be going under failure. So, it is the most important and complicated testing type.

Operational Acceptance Testing (OAT)

This testing mainly used to determine the product’s compatibility, reliability, stability, etc., before it is going to live.

Alpha Testing

Specialized Testers will perform this testing to check any bugs have occurred. Also, they help to give suggestions to improve product usability in a controlled manner.

Beta Testing

Beta Testing helps to grab the bugs or any issues of a product. End-Users will perform this testing with an uncontrolled manner.

Best Example to understand this testing

• During the process of manufacturing a mobile phone, there are so many parts like a camera, speakers, flashlight, buttons, display, headset, charger, etc., will be produced separately by different manufacturers.
• All these parts will first go under unit testing
• After unit testing, they go for integration testing.
• Later, system testing will be performed
• Finally, acceptance testing will be performed before it is out for delivery.

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 system.
• 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
• Install Testing
• Localization 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
• Regression Testing
• Recovery Testing
• Migration Testing

Types of System 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

Methods of Software Testing | Advantages and Disadvantages | W3Softech

Methods of Software Testing:

There are three methods of software testing available namely Black Box Testing, White Box Testing and Grey Box Testing.

Black Box Testing:

Black Box Testing is a method of Software Testing also called Behavioral Testing. The main function of black box testing is to test the interior design/implementation of an item which cannot be known to the tester. The name itself says that the tester who is going to test the product will give input and examine the output results without having the prior knowledge of source code.

Black Box Testing helps to determine the following aspects:

• Finding errors at the initial and final stage
• Optimizing the interface errors
• Checking errors or missing functions
• To check and verify the errors in the external database

Advantages of Black Box Testing:

• More Efficient and Suitable for large code segments
• No need for any Coding or Programming knowledge
• A large number of testers can test the software application without prior knowledge on programming or operating system
• Design of Test Cases

Disadvantages of Black Box Testing:

• Only limited coverage of application as the tester cannot target specific code segment
• Test cases are difficult to design as the tester doesn’t have prior knowledge on specifications and coding
• Some possible inputs will only be tested

White Box Testing:

White Box Testing is one of the methods of software testing also known as Open Box Testing, Transparent Box Testing or Glass Box Testing. It is defined as a testing method in which the tester can able to test the internal functions of a product with prior programming knowledge under specific conditions. The major role of this testing is to study the whole internal structure of a software product and need to find out the inappropriate unit code.

Advantages of White Box Testing:

• It helps to optimize the whole internal source code as the tester is having programming knowledge
• Almost all paths of a software product will be covered
• As the tester is having programming knowledge it will be easy to find out the inappropriate unit code

Disadvantages of White Box Testing:

• Requires highly skilled testers and debugging tools
• Results will be more efficient but according to resources it may become expensive
• Even though all paths of the source code will be covered there may be a chance of missing to find out hidden errors

Methods of Software Testing

Grey Box Testing:

It comes from the combination of the black box and white box testing. Grey Box Testing is also one of the methods of software testing. It helps to test the partial or limited paths of the internal structure of a software application. It is known as Gray Box or semi-transparent box testing. The name itself says that the tester can access limited paths of the application.

Advantages of Grey Box Testing:

• The main advantage is that the tester can perform either black box technique or white box technique even both
• Testers don’t need to rely on the source code
• As there is a limitation of software testing, the tester can able to design perfect test cases or scenarios

Disadvantages of Grey Box Testing:

• As there is no full access of source code, the tester can able to cover a limited area of the software application
• There may be a chance of occurring redundant if the designer already starts the test case
• The major disadvantage is that software product cannot be tested fully as there are limitations
