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

What is Integration Testing? Types, Tools and Strategies – W3Softech

Integration Testing

The process of testing the combination of units or integrated units of a system or product is called Integration Testing. It is the second level of software testing and helps to test the multiple modules of software written by different level of programmers. It is also said to be String Testing or Thread Testing. Also one of the levels of testing usually performed by developers or software testers.

Working Process of Integration Testing

• The initial step is to prepare the tests plan
• To design the test cases, test scenarios and test scripts
• To execute the test cases
• Optimize the test cases
• To perform re-testing to ensure that the system is defect-free

Integration Testing Types/Strategies/Approaches

There are 4 different testing approaches namely

• Big Bang Approach
• Top-Down Approach
• Bottom-Up Approach
• Hybrid/Sandwich Approach

Integration Testing Approaches – W3Softech

Big Bang Approach:

Big Bang Approach is nothing but testing by combining all the functional units at the group. This approach will take place after receiving the software at once.

Top-Down Approach

Here top-level units are going to be tested first later lower level units will be tested one by one. This approach takes help of Test Stubs to perform testing on lower level units

Bottom-Up Approach

It is quite opposite to the Top-Down Approach. This approach takes help of Test Drivers to perform testing on top level units

Hybrid/Sandwich Approach

This approach is the combination of both Top-Down and Bottom-Up Approaches. Here top-level units and lower level units are tested. It takes the help of both test stubs and test drivers

What is Unit Testing? Unit Testing Tools and Types | W3Softech

Unit Testing

The process of testing the individual units of software is called Unit Testing. It will be done during the development of a software application. According to the programming procedure, a unit may be an individual function of the software.

Unit Testing is one of the levels of software testing and usually done by the developer. It is the first level of testing. Developers or QA Engineers will handle this testing.

Working Process of Unit Testing

• With the help of this testing, we can fix bugs or errors during the development cycle
• It enables developers to make changes quickly and saves cost
• It helps to get a good quality software product

Unit Testing Types

It is of two types namely Manual or Automated.

Most probably performed by manually but developers always prefer to do automation testing. It is a white box testing technique comes under following test coverage techniques

• Branch Coverage
• Condition Coverage
• Decision Coverage
• Statement Coverage

Using White box testing methods

• Test cases can be derived that all independent paths within a module have been exercised at least once.
• Exercise all logical decisions on their true and false sides.
• Executes all loops at their boundaries.
• Exercise internal data structures to assure their validity.

Unit Testing Tools

• JTest
• JUnit
• NUnit
• JMockit
• EMMA
• PHPUnit
• xUnit.net
• TestNG
• QuiltHTTP
• HTMLUnit
• EmbUnit
• SimpleTest
• ABAPUnit
• TypeMock
• LRDA
• Cantata
• Karma
• Jasmine
• Mocha
• Parasoft

Advantages

• Developers will be able to understand the functionality of the Unit API
• It helps the developers to rewrite and modify the code anytime and ensure the unit works as usual
• It helps to test each and every unit of the software application so that named as Unit Testing

Disadvantages

• It is very complicated to test each and every unit in large scale programs as it takes a lot of time
• There may be a chance of missing units or paths of code in trivial programs
• It allows testing only certain units or paths of code so that we are unable to grab the integration errors

What is Agile Testing? Agile Testing Methodology and Life Cycle | W3Softech

Agile Testing

          Agile Testing is a process of software testing which follows the agile software development principles. It is non-sequential but to start with continuous integration between testing and development. The main aim of agile testing is to achieve high-quality product within a short period of time. It consists of short time frames called iterations so that it is also called delivery driven approach.

Agile Model vs. Waterfall Model:

          Agile Model is used while working with an agile methodology and the waterfall model is adopted from a waterfall development approach. Both are different methods of software development process even though they are different but both are important based on the requirements and type of project. The major differences between the agile model and waterfall model are listed below

Agile Model	Waterfall Model
Testing process of agile model is unstructured compared to the waterfall model	Waterfall Model Testing process is structured with maximum planning
It is best suitable for small projects	It can handle all kind of projects
Agile Model helps to fix errors in the middle of the project as it starts with the beginning of the project	In the waterfall model, errors need to fix from the beginning of the project as it tests at the end of the project
As agile testing contains short time frames it requires less documentation for the testing process	Whereas waterfall testing requires big data of documentation for the testing process
Agile testing can take place at every stage of project development	Waterfall testing is able to begin only after completion of project development
Here testers can work along with developers	Here testers and developers need to work separately
To analyze the project requirements testers need to maintain communication with developers	Here there is no need for any communication between developers and testers as they work separately
In the agile model, acceptance is able to perform at the end of every sprint	In the waterfall model, user acceptance can perform only at the end of the project

Agile Testing Methodology:

As there are a number of methods available for agile testing, these two plays a major role in the development process

Test Driven Development:

• It uses tests to direct and drive the development process to write an automated test before writing the code. There are two levels of testing available here namely Unit Testing and Acceptance Testing
• Unit Testing comes under white-box tests which confirm developers expectation of developing the code with the help of tools usually xUnit Framework tool
• Whereas Acceptance testing comes under black-box testing which confirms the customer’s expectation of system capability with the help of tools usually FIT Tool
• It helps to run all the tests whenever new code is checked-in at all the time

Continuous Integration:

• It keeps the main development code-line clean to ensure that the whole product works correctly on the whole time to provide a high quality product
• Both tests such as Unit and Acceptance Tests are going to execute whenever any new code is checked-in to build 100% defect-free code-line
• TDD helps to make sure that your own code is correct whereas CI make sure that code-line is defect-free without any regression

Advantages and Disadvantages of Agile Model:

Advantages	Disadvantages
It helps to make good communication between testers and developers	Need highly skilled testers and developers to analyze the project requirements
Agile Model consumes less money and time	Only suitable for small projects
It is very flexible to use and easily adaptable to changes	This Testing process required unstructured data with minimum planning
Any changes can be made in the middle of the development process	Sometimes it may get failed due to lack of software deliverables

Agile Testing Life Cycle:

Requirements:

Gathering basic requirements for a project to move it into an agile development process. It helps to make perfect planning to start a project

High-level planning:

Make perfect planning to begin a project with the help of testers and developers

Designing:

Make sure to establish perfect communication between testers and developers so that we get the best design of a project

Development:

After successful completion of designing, we need to move the project into development for better output

Test:

Here is the major step takes place which is Test. The complete project needs to be tested to make it defect-free

Deliver:

Need to deliver the project to the customer within the required period of time

Review:

After successful delivery once review the working practices of the project and make sure it is fine

Feedback:

Finally, take feedback from the customer to improve the next deployment cycle
